Chromecast local files from Linux - supports MKV, subtitles, 5.1 sound and 4K!

Gnomecast

This is a native Linux GUI for casting local files to Chromecast devices. It supports:

• Both audio and video files (anything ffmpeg can read)
• Realtime transcoding (only when needed)
• Subtitles (embedded and external SRT files)
• Fast scrubbing (waiting 20s for buffering to skip 30s ahead is wrong!)
• 4K videos on the Chromecast Ultra!

What's New

• 1.9: Multi video/audio stream support.
• 1.8: 5.1/7.1 surround sound E/AC3 support.
• 1.7: Drag and drop files into the main UI.
• 1.6: Mutiple file / queuing support.

Install

Please run:

$ sudo apt install ffmpeg python3-pip python3-gi
$ pip3 install gnomecast

If installing in a mkvirtualenv built virtual environment, make sure you include the --system-site-packages parameter to get the GTK bindings.

Run

After installing, log out and log back in. It will be in your launcher:

You can also run it from the command line:

$ gnomecast

Or:

$ python3 -m gnomecast

You can also configure the port used for the HTTP server via the environment variable GNOMECAST_HTTP_PORT:

$ GNOMECAST_HTTP_PORT=8010 python3 -m gnomecast

Please report bugs, including video files that don't work for you!

Tests

Run the tests from the commandline:

$ python3 test_gnomecast.py

My File Won't Play!

Chromecasts are picky, and the built in media receiver doesn't give any feedback regarding why it won't play something. (It just flashes and quits on the main TV.) If your file won't play, please click the info button:

And then the "Report File Doesn't Play" button:

So I can fix it!

Thanks To...

And everyone who made this project hit HN's front page and #2 on GitHub's trending list! That's so awesome!!!

Transcoding

Chromecasts only support a handful of media formats. See: https://developers.google.com/cast/docs/media

So some amount of transcoding is necessary if your video files don't conform. But we're smart about it. If you have an .mkv file with h264 video and AAC audio, we use ffmpeg to simply rewrite the container (to .mp4) without touching the underlying streams, which my XPS 13 can at around 100x realtime (it's fully IO bound).

Now if you have that same .mkv file with and A3C audio stream (which Chromecast doesn't support) we'll rewrite the container, copy the h264 stream as is and only transcode the audio (at about 20x).

If neither your file's audio or video streams are supported, then it'll do a full transcode (at around 5x).

We write the entire transcoded file to your /tmp directory in order to make scrubbing fast and glitch-free, a good trade-off IMO. Hopefully you're not running your drive at less than one video's worth of free space!

Subtitles

Chromecast only supports a handful of subtitle formats, .srt not included. But it does support WebVTT. So we extract whatever subtitles are in your video, convert them to WebVTT, and then reattach them to the video through Chomecast's API.

Video files with multiples audio tracks

Hi there! Thank you for the great job!!
But I can't figure out how to select desired audio track from a "dual audio" video file.

Sorry if it's a dumb question.

Chromecast gives up after waiting.

This is basically a re-opening of #60 but I was pretty unresponsive on that issue and it seems like it got sidetracked into an unrelated problem. Feel free to close/reopen as desired.

Link to audio file I was trying to stream

I'm on Gnomecast 1.4.1, and uname -a is

Linux <snip> 4.13.0-38-generic #43~16.04.1-Ubuntu SMP Wed Mar 14 17:48:43 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

The full log of opening Gnomecast from the terminal, and trying to stream the file:

And it just hangs there.

The device is recognised correctly so I am unsure what the problem can be. I also checked the transcoded file saved in /tmp and it seemed to be fine too. Maybe I need to open up some port?

support different subtitle encoding

Due to MS Windows, many (maybe most) non-english subtitles available are not UTF-8 encoded, but instead use a local Windows codepage. In my case, 99% Czech subtitles I can find on the internet are in CP1250. All decent media players (VLC, etc) support this and allow you to set default subtitle encoding. Unfortunately it seems that gnomecast insists the subtitle file must be UTF-8 encoded (I see broken non-ascii characters when casting).

Can you please add support for specifying the subtitle file encoding, so that I don't need to recode all my subtitle files by hand?

Thanks!

Add support to connect directly to chromecast via IP

This is really cool. Thanks for making this!

For some reason I can't get chromecast discovery to work with my network/router, but I can figure out the IP and verify that ports 8008 and 8009 are open and I can query some info about it on port 8008 using curl.

I played around with the https://github.com/balloob/pychromecast library and can successfully build ChromeCast() object just using the IP.

Can you add support for connecting to chromecast via IP? As in something like:

gnomecast -d "192.168.1.100"

Cheers

add OSX support

I know, I know, OSX isn't supported. Guess what; with all of the prereqs installed (and the fix for High Sierra's idiotically broken hostname handling[1]), it starts and runs just fine!

The solution (for now) is:

2. pip install bottle pychromecast pydbus gnomecast (the first three should really be auto-installed)

Share screen and audio playback?

Would it be possible to add support for sharing the screen content and audio playback?

Allow user to specify file in command line arguments

It would be nice to be able to do the following:

$ gnomecast some_song.mp3

It does not appear command line arguments are being used for anything else at the moment.

Shutting down kills other stream

Steps to reproduce:

1. Start streaming with Gnomecast.
2. Stop streaming with Gnomecast, but keep application on.
3. Start streaming with another application towards the same Chromecast.
4. Shut down Gnomecast.

Expected behaviour:
The new stream continues.

Actual behaviour:
The new stream is aborted.

This is the information I see when loading my video:
file.mkv mkv h264 True True False True
['ffmpeg', '-i', '/media/yehuda/folder/file.mkv', '-c:v', 'copy', '-c:a', 'mp3', '/tmp/movie_caster_p81pwax9.mp4']

Thanks.

Videos fail to report conversion rate

Loading a short (<10s) video to investigate other bugs, I got the following in my logs:

Traceback (most recent call last):
  File "/home/jiby/Documents/dev/foss/gnomecast/gnomecast.py", line 312, in f
    self.update_status()
  File "/home/jiby/Documents/dev/foss/gnomecast/gnomecast.py", line 288, in update_status
    notes.append('Converting: %i%%' % (self.transcoder.progress_seconds*100 // self.duration))
TypeError: unsupported operand type(s) for //: 'float' and 'NoneType'

I suspect the video's length is at fault, causing the update_status to be too small == None.

Probably related: after successful video playback on Chromecast, the Gnomecast GUI is frozen to ~80% of video, instead of 100%, which is not neat, and could cause users to worry about missing out a bit of video.
I'll make a PR for that separately if needed.

MKV audio track selection

I have to open up another issue right again :P

In this case, I'd like to be able to choose the audio track, as some movies have them in several languages.

support chromecast audio

Does it support chromecast audio?

Use subtitles in MKV

Hi!

It would be nice if Gnomecast would support selecting amongst the subtitles within the mkv container. As it stands now, one must first separately extract them and then manually select them.

Any plans on making a playlist or the ability to select a folder?

This would be a great feature!

Add the GnomeCast logo to the title?

Would it be cool if we added the GnomeCast logo in the title?

GnomeCast

Should somehow make the image move down to aline with the text.

use /var/tmp

/tmp is on many distributions a tmpfs device, only useful for storing small temporary files. Large temporary files (like a transcoded video) should not go there, but instead go to /var/tmp. Please use /var/tmp by default; or if you insist on /tmp, please detect whether /tmp is a standard dir or a tmpfs dir and adjust the behavior dynamically.

Thanks!

can't cast video after audio

(Sorry for my english)
if you want to cast video after having casted audio, previous audio is casted instead of video

Threads arg in ffmpeg command

You should be careful where you put the -threads arg in the ffmpeg command. Really sure you need 4 threads to decode? See the answer and the prolific Lord Neckbeards comment here:

During handling of the above exception, another exception occurred:

Seems non-standard Screensaver bus location (it's hit me before on this laptop) causes an exception that is not handled.

Investigation

I'll dig into the the issue on my side of why I have no such dbus name available. That seems legitimately important for other people in my unfortunate case to try to get the correct name.
The uncaught exception is for sure an immediate issue, and I'll prepare a PR soon, but I need to understand what kind of fallback mechanism is expected if we legit can't find any Screensaver handle.

I tried casting to my chromecast device (built-in, Android TV) and it seems to succeed in finding the device and connecting to it but the streaming never starts (even when no transcoding is required). Running on a KDE Neon (based on Ubuntu 16.04).

New screenshot with the new title?

Not sure if this necessary, but replacing the screen shot with the title GnomeCast with a new one would be nice because it is not called GnomeCast anymore.

Enqueue multiple video files

It would be pretty neat if I could select a couple of episodes (or an entire season) of a TV show to cast through Gnomecast.

1. The next episode can transcode during the current one for less delay
2. I can play multiple videos in a row without having to touch my laptop

delay reinstating screensaver

if the video is paused we reinstate the screensaver. this has an annoying property of if i pause w/ the tv remote, the screensaver immediately turns on on my laptop. we should prob. have a 10m timer to re-instate the screensaver.

inhibit screensaver?

should we inhibit the screensaver while casting? looking for opinons. the purpose would be to keep the play/pause controls available while watching something.

possible mechanism:

Casting fails with repeated "waiting for transcode to finish" linux mint 18.3

My deepest apologies for being the sort of Linux user that knows barely enough to be dangerous, but I'm very interested in using this tool. I had some trouble with the Python 3 dependencies, but I think I worked through them--though when I finally got a working copy of gnomecast to install, I received a "failed to build wheel" error for gnomecast and several dependencies. Launching gnomecast finds my chromecast device, and I can choose an .mkv file to stream, but transcoding makes no progress (remains at zero percent) and receive endless "waiting for transcode to finish" messages in the command window. Choosing an .m4v file works as expected

Selecting file after successful stream crashes

Hi Mr owner, love your work, was able to use Chromecast natively from Linux for first time in a while!

Today's (second) error is triggered by selecting a file after having successfully streamed through an entire file. In my case I'm looking at a TV series, so I waited till end of one full episode and selected the second one.

I get the following:

Reliably reproduced after watching another episode.

Seems we're closing a session too early somewhere because streaming succeeded, despite the application not being done running.

I'll try to trace the issue more and submit another PR.

automatically find a subtitles file with the same name as the Video

Hello

Thanks for this great tool.

If a video file and a .srt file have the same name, is it possible, after choosing the video file, to offer as default file for the subtitles, the associated subtitle file?

Example

$ ll 800*6*
-rw-r--r-- 1 gg gg 367257633 avril 16 19:30 800_Words_Series_1-_6.Episode_6_b08vl92r_original.mp4
-rw-r--r-- 1 gg gg 88911 avril 16 19:30 800_Words_Series_1-_6._Episode_6_b08vl92r_original.srt

If I select as video file

800_Words_Series_1_-_6._Episode_6_b08vl92r_original.mp4

and

800_Words_Series_1_-_6._Episode_6_b08vl92r_original.srt

exists, then propose this file by default.

Regards

add key bindings

clicking on the button is annoying. need:

• space for play/pause
• left-right arrows for fwd/rev
• up/down for volume?

maybe hardware media keys too?

if the focus is on the button, what should we do? should we blur after click? what does that do to usability? maybe should we blur after a timeout? should we always pass the keyevent up to the parent?

Make a contribution list

Since we've got 5 people contributing to this project, I feel like it is time we put list of the contributers in the README.md

We should use this all contributors method to show the contributors of gnomecast.

implement a max height for the UI

re #59 we want to support screens sized 1024x768, and make sure our UI never grows taller than that. somehow impl a max screen height around 768, cropping the screencap if necessary.

Can't add subtitles

Hey!

I've been having problems with adding subtitles to movies. The file selection dialog opens fine, but clicking either "add" or "cancel" has no effect, and the dialog has to be closed via Alt+F4.

Desktop app name should be GnomeCast not Gnomecast

Here is the app name in the launcher

And here is the app name on the app

Not sure how to change that. But would be nice if you could tell me how so I can learn something new :)

No sound

I'm using Debian testing, I've installed gnomecast as described by a cannot hear any sound while playing a flac file to my Chromecast Audio.

setup.py and MANIFEST.in still reference cast.png

deleting cast.png broke the pip install "error: can't copy 'cast.png': doesn't exist or not a regular file" because it's still referenced.

Consider still including the logo as a file. It's useful to have one for making a .desktop file to add a Gnome shell launcher.

Do not use gtk_dialog_run

gnomecast/gnomecast.py

Line 260 in 039d264

dialog.run()

You should instead connect to the response signal of the dialog and show the dialog. This way you will not block the mainloop. Also you can avoid that idle that you have there.

Progressive transcoding to start streaming immediately

I'd love to be able to make transcoding a file into a chunked process, so that we don't have to wait for the file to be completely transcoded to start streaming.
This would improve usability on big files like movies.

I know VLC has this feature on Android (and maybe even in their 3.0 release desktop), but I suspect they reimplemented completely the Chromecast controls to be able to do it.

Required steps

1. Check the chromecast mediacontrols API for direct support of chunked streaming
2. Change calls to ffmpeg to only transcode chunks of X seconds (one minute sounds like a good first pass)
3. Update the scrubbing system accordingly and any other API.
4. PR and enjoy fame and fortune

I would naturally love to help on that new feature, I'm not just complaining here :)
Any thoughts on this ?

Firewall settings

I'd like to add the appropriate rules for firewall (GUFW) but I have not been able to find any reference to the correct ports. As it currently stands, I have to disable my firewall to cast from Gnomecast or VLC3. Has anyone successfully added rules to their firewall?

Error when installing in a virtual environment: ImportError: No module named 'gi'

Got the error in the title on pip3 install gnomecast.

Traced it down to the following:
Because I first created a virtual environment with mkvirtualenv -p /usr/bin/python3 gnomecastenv, I accidentally excluded the system wide packages, including gtk and gi.
If running inside a virtual environment, system wide packages are not included by default. By building the environment with "--system-site-packages" everything works.

This is already solved, so I'm just putting this here to help any other folks trying to work it in a virtual environment.

add a desktop shortcut so you don't have to run it from the command line

see #10 for my WIP. help getting this working would be much appreciated.

We need a logo for GnomeCast

maybe a mix of the gnome logo and chromecast logo

Converting more than once

I started playback and then stopped, searched network again and started playback again. gnomecast converted my file for the second time. Would be nice to avoid that by storing a temp file with the converted content.

Oh, and thanks for the great work, it's the most convenient chromecast app I've used.

add more cmd line args

outgrowth of #24

should support:

• --subtitles / -s
• --device / -d (friendly name of device, "Bedroom TV", etc.)
• --play / -p (autoplay)
