Allow folks to put their own image in the splash screen. Also time for a favicon

Hello,
It would seem that the following step in the Requirements.txt file is failing to install through powershell.

pygame==1.9.6; sys_platform != 'darwin'

I attempted to skip it by removing it from the txt file and retrying the install command. The rest of the install continues, but pikaraoke doesn't load.

Loving this app. An awsome option would be to also have another drop down to add regular videos and keep them kinda separated and add them in on the queue as well. Kinda how bars do it where they throw a few videos in between singers.

I have confirmed that the normal audio/video works through the hdmi and even 3.5mm with pikaraoke.

I bought a HiFiBerry Soundcard Hat, however, and after making the changes to use alsa:hw:0,0 vs both, I only get a blank/black screen with no audio. I have confirmed that the sound comes out using the same omxplayer command generated by pikaraoke with no issues without pikaraoke.

Any ideas on what could cause this behavior? If I/we can get this to work, I would be happy to try and make the “output” an argument to app.py.

You can see the change I did here:
master...bennysp:master

Here is a debug output to confirm what I am seeing:

Blank/Black Screen & no audio

have a nice day ;)

In a few drunken party situations, we had the queued songs all disappear. I can't tell if someone did this on accident or if it's a bug. Obviously nobody would 'fess up. If someone finds repro steps, please post them here

Worked fine 2 days ago. I updated the YouTube url deal in the settings but still can no longer search and add songs. Just an empty web page that says server is down or busy. Not sure what to check.

Internal Server Error
The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.

I have a CDG library and would like the ability to incorporate those files into the pikaraoke library. Is there any chance you could add CDG support? I know VLC has some support for the format although it requires selecting both the mp3 and CDG files simultaneously then playing. There's also libCDG in the OpenKJ project that is quite a bit more sophisticated.

I have tried to edit a song with the same "title - artist" filename, it seems it is overwriting the existing file. I'm trying to pull a request to at least allow the same "title - artist" filename but having an index (i.e. "title - artist (2)") filename.

Hi, I would like to use your pikaraoke on my raspberry and I would like to display karaoke on a screen of my parents.
With a confinement I can't see my parents to do karaoke, also I would like to know how I can use karaoke on my raspberry pi in my home and send karaoke link for my parent.

Too easy to skip a track on accident. Best to add a confirmation dialog

When using inverted commas in the search field it just errors out.
Example:
Nothing’s Gonna change my love for you

Internal Server Error

The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.

Search/download fails miserably on foreign language song titles. Special character handling is not python's strong suit, need to research better ways to escape these

It occurs to me that there might be a youtube-dl option we could use to detect videos containing only a static image (implying there are no on-screen lyrics). It feels like more than half of the search-hits claiming to be karaoke tracks are audio-only rips with a screenshot of the cover of the disc instead of lyrics. It would be great to be able to distinguish the search results list to highlight (or rather 'low-light') the titles of such videos, if a method could be found to detect them.

A more complete solution might be to provide a side-search option for a lyrics page to display over such audio-only backing tracks. Not as good as a proper rolling karaoke live-lyric visual, but far better than no lyrics at all. For now, though, I'd be happy with a lyric-less detection method.

Program works fine when using --hide-splash-screen. But when splash screen comes up and you que a song, you see the 'next up' notification in the bottom corner, and then you hear the song playing, but the splash screen doesn't go away.

Noticed this in a few large group sessions: a blank song gets added to the queue. When trying to delete it from the queue, the current song skips.

Not sure how this is happening. Perhaps double-submitting to queue, bad chars in the title, etc.

Is it possible to configure a Raspberry Pi4 for dual-screen video playback (i.e. cloning the karaoke lyrics onto a second monitor) on a Raspberry Pi4 using the second HDMI output)?
I've tried several screen-extension options and while they replicate the desktop background (and in one case even replicated the icons on that desktop), when PiKaraoke is run the logo/QR-code display screen is expanded sideways to fill the two monitors as one super-wide Extended Desktop with the logo divided across their shared boundary, and the karaoke lyrics video still only appears on the primary monitor.

Does anyone know of a way to clone the karaoke visuals to both HDMI outputs?
e.g. maybe as a modification to the omxplayer launch command?

I know there's something 'special' about the way the karaoke visuals are displayed, as I had tried RealVNC to do the cloning and had to apply an Advanced Option in RealVNC Server to get it to render the lyrics video stream at all (otherwise it just VNC'd the logo screen). Does this observation provide any clues to how a cloned video stream might be routed through the second HDMI?
(Even with the advanced mode applied the results with RealVNC were not great - if there's any background graphics movement at all the latency, block-artefacts and frame-dropping made it unusable)

Thanks in anticip...

Trying to install on Lubuntu and followed all the instructions and installed all dependencies. When run the program I get the message:

Youtube-dl path not found! /usr/local/bin/youtube-dl

I have tried manually creating the folder but still didn't fix the issue

Search of content not previously stored has stopped working and updating youtube-dl isn't fixing it.
A bit of digging reveals that the hosting repository at yt-dl.org is currently pointing to a GitHub DMCA take-down notice.

Could you refactor and add the VLC as another supported player? There are a few benefits to it:

• more distros supported by VLC. I couldn't compile omxplayer on manjaro/arch
• VLC has a filter to change pitch via UI. I'm not sure if it could be accessed via cmd, but that is possible for a future version.
  Thanks for this awesome work

probably need some kind of UI to configure wifi. Bringing the device over to a buddy's house and trying to set up wifi via CLI is no fun.

The ability to choose to download higher quality video would be great. Maybe a checkbox? The default works perfectly for karaoke files, but it would be great to be able to choose best available quality for sing-along music videos.

Anyone having an issue where it wont let you search anything? If i type in a search term. The page just refreshes and no search results come up.

The logs shows 'Searching YouTube for: Yellow'

And it just ends there.

I'm able to launch the browser and surf the net if i close out the app. Not sure what I'm doing wrong :(

Hi vic...

When installing the rep on a new RPi 4 last week I found that a fairly recent update to omxplayer appears to have broken queue playback in pikaraoke (error scenario virtually identical to : (popcornmix/omxplayer#736) ).

Search, selection and queue management functionality still works, but the queue aborts each song as soon as it attempts to load for display, selecting instead the next song in the queue, aborting each one until the queue has been exhausted.

I discovered that I'm able to run pikaraoke if the --hide-overlay and --hide-ip CLI options are invoked. This has the effect of removing the display of the QRCode graphic and the IP address:port combo in the splash screen (but somehow the display of the title of the next song along the bottom of the splash screen is unaffected)

I love the software! Very clean and easy to use; but I am running into an issue. I think I've isolated pretty much everything. When I play a video using pikaraoke and have the audio output via the audio port to an external speaker there is a ton of distortion and a whining sound on all the songs. Oddly enough though when I take the same mp4 file and play it directly in VLC Player on the rpi OS (not from within pikaraoke) the audio is perfectly fine (again still coming out of the audio jack to the speaker, NOT via hdmi). Is there some sort of setting that would be distorting audio only via the pikaraoke software?

At first I assumed it was hardware and swapped out power supplies, speakers, different electric outlets, different cables. After all that I finally tried just playing the video from within VLC player and it sounds fine. I'm running on a new raspberry pi 4 (no HAT sound card) and I just installed the OS and pikaraoke today so the codebase is also new. Any thoughts?

Some kind of admin mode would be nice. When not admin, the following features would be disabled:

• Player Control
• Queue editing
• Add 5 random songs
• Clear all
• Edit song name
• Hide all the System Info / Updates / Shutdown features

Think I'm connected to a guest network as the IP4 address is coming out as 10.x.x.x. Can the program still run or does it have to be in the home network? My phone also has the same 10.x.x.x IP but I can't connect to the GUI. I initially was trying to assign a 192.x.x.x static address but was losing internet connection.

System: Linux Mint 19.3 Xfce

If I missed a disclaimer in the instructions, I apologize in advance.

Hi, I'm getting some errors installig the pikaraoke.
When I run the command sudo pip install -r requirements.txt I receive this error:

Can u help me? Thanks

it is not possible, I already did the basic configuration of both analog and bluetooth, I want to project with hdmi but capture the sound in another way

Hi there,

When trying to launch the app, I'm getting the following error. Any thoughts here? Also, does the youtube-dl issue impact the program working completely or just is that for downloading songs in advance or something?

Traceback (most recent call last):
File "app.py", line 9, in
import cherrypy
ImportError: No module named 'cherrypy'

The Usage section defines the command line options as (still) including '--hide-overlay' but the option description has been (correctly) updated as '--show-overlay'.

We have our TV wall mounted and the top of the TV is near the ceiling making it hard to reach to get the QR code from some of the more vertically challenged friends.

Add a start load option to identify the quadrant to place the QR code.

Hi @vicwomg Im not really familiar with cherrypi. Is it possible that the mp4 files can be access through http?

What I wanted to achieve is to be able play/preview the karaoke songs via http (clients phone) and possibly create a basic trim video function using ffmpeg.

Now that VLC is available as the player, pitch change becomes feasible.

I haven't got the Python skills to implement it in code, but I've discovered that the VLC command-line provides for pitch-change using the option sequence
--audio-filter=scaletempo_pitch --pitch-shift=n
where 'n' is the signed number of semitones of transpose to be applied to the audio track. It has a range of -12 to +12 (+/- 1 octave).

VLC does throw some errors when running it from the CLI but it still plays the chosen mp4 with the pitch-change applied.

I have to say it sounds disappointingly 'warbly' but there are some filter config parameters that might provide some adjustment to improve this (I haven't tried to experiment with them yet). These are to be found in the [scaletempo_pitch] section of the file ~/.config/vlc/vlcrc
The parameters provided are Stride Length, Overlap Length, Search Length and Pitch Shift. I notice that in the file Pitch Shift is a float, but at the command line it seems that VLC only accepts certain multiples of 0.1
There's some explanation of these terms here (search for scaletempo)

I'm having audio problems
after doing the volume up on the web view
get the annoying noise

raspberry py 4 B

Thanks to @petemarvin 's update to support VLC we should be able to port pikaraoke over to Linux, OSX, and Windows. While I'm at it, I'd like to make the project python3 compliant, since python 2.7 has reached end-of-life.

I am using a raspberry pi 4 and am coming accross two stumbling blocks

Once I try to install the python dependancies with [sudo pip install -r requirements.txt] I get the message that
"tempora requires Python '>3.6' but the running python is 2.7.16"
I have checked the version of python and python3 running on my pi using [pyton --version] and i get python 2.7.16 and pyton 3.7.3

Continuing to follow the instructions once I try to run the app, the following error message appears:
Traceback (most recent call last):
File "app.py" , line 11 in
import karaoke
File "/home/pi/Desktop/pikaraoke/karaoke.py", line 12, in

Thank you very much for any help that you can offer!

and thank you for an awesome project, I cant wait to get it up and running in time for christmas if you can help me with the set up

i have pikaraoke all set up and working great with the default settings. I would like to save to my shared drive on another PC but im doing something wrong. I have pikaraoke set up in rc.local so it auto starts. My shared drive is \DESKTOP-MKD79SO\Shared Drive\pi\karaoke. I have it setup like this...but its not downloading to the shared drive and im not sure where its going but it is downloading on the pi somewhere. Is this right?

/usr/bin/python /home/pi/pikaraoke/app.py -d "\DESKTOP-MKD79SO\Shared Drive\pi\karaoke" &

exit 0

The search method forces "karaoke" at the end of the search string to return karaoke results. This works most of the time, but may be too limiting, as some karaoke results could show under "lyrics" "instrumental" or "raw". We should allow some way to disable the "karaoke" string and just allow a basic plain text search.

Perhaps a checkbox under the search input "include non-karaoke matches" and a new search mode, like an optional parameter on the search method karaokeOnly=true.

youtube-dl gets out of date pretty quickly. Would be great to give users ability to update it without dropping to the CLI

If there is an active browser trying to fetch from /nowplaying (probably from a previous karaoke session) the app will throw exceptions during start up. Best to catch and handle them.

The pi setup script does a scripted edit to change the gpu_mem:

"You will then probably need to reboot since this changes a boot setting (gpu_mem=128). This is to prevent certain videos from showing visual artifacts (green pixel distortion)?

This was necessary in older pis running omxplayer, but perhaps vlc is better at handling it. Should double check and evaluate whether it can be removed. Don't want to mess with pis in unexpected ways unless it's absolutely necessary. I'm actually pretty sure pi4 doesn't need this at all. So perhaps some board detection would be good too.

Using VLC via --force-vlc on a Raspberry Pi does not allow audio to output to the headphone jack and only works on the HDMI audio output. I have configured the Raspberry Pi to default to audio output to Headphones (raspi-config) and running VLC from the command line plays the output on the headphone jack and HDMI output. When playing a file from pikaraoke, the output is only to the HDMI output with the following logging info:

The difference here being that vlcPulse audio is being pulled in when using pikaraoke and not when using VLC via command line.

VLC has enough benefits (key change, x-platform support) that it should be the default player on pi instead of omxplayer.

We can still support Omxplayer for slower devices, and it would also be great to move it into it's own client library like vlcclient.py to get rid of all the gnarly if logic in handling one or the other.

Hello - I've successfully installed the app on other OS's and I just tried to do so on windows 10.. I ran into a number of issues but finally got through most of them but now I'm getting some stack traces when running the app. The splash screen does in fact load but I'm unable to go to the IP address (while on the network) and debug logging shows a number of errors. I will say this is a new computer so I don't know if I installed the correct visual studio components; there seem to be a ton of option. I installed the C++ redistributable files from 2010, 2012, 2013, 2015-2019. Attached are the errors I'm receiving.

Hi,

If your PI has both an IPv4 address and an IPv6 address, the QR code actually puts both addresses instead of picking one. So you cannot use the QR code.

Thanks for the great work!

In desktop mode, where I suspect the majority of pi users are running this from, sudo is actually not necessary because it has a window server. Sudo is necessary running from a non-desktop CLI because it needs access to the hw screen buffer.

Thus, the only real thing preventing non-sudo operation is that the default download directory is /usr/lib/pikaraoke/songs
If we change this to ~/pikaraoke/songs then it should allow folks to run non-sudo.

Previous users who already have the old dl directory may experience songs "disappearing" after update though. To handle this there should be some detection for this older directory and throw a warning log on launch that they either need to launch with the -d /usr/lib/pikaraoke/songs or move their songs over to ~/pikaraoke/songs

Opened from #65

Running app renders hostfile/dns IP in QR code rather than DHCP IP. Current workaround is to comment out IP information from hostfile

Edit: Specifically, on Lubuntu Linux distro

Hi

Running 3.5.3 on new raspbian (minimal version) and new install. Tried the workaround in the other thread, but this is stopping me.

Good suggestion here:
#54 (comment)

If there is an issue searching for a specific track, a user should be able to override the default search by pasting a YouTube URL directly into the search field and download it. This url can be obtained from a browser or the Youtube app.

Considerations:

• How to reliably detect a YouTube url? (mobile variants, query strings, case sensitivity)
• How to make this clear in the UI? Minimal verbiage below the search input? Already pretty wordy there. Changing the button text to "download" if a url is detected?
