Basic capture and play programs for Blackmagic Design Decklink

BlackMagic devices tools

Initially developed as an example integration between libavformat and the bmd sdk, it ended up being a set of useful tools to use the BlackMagic Devices decklink cards on Linux and macOS.

Thanks to TodoStreaming sponsoring its early development.

Build instructions

In order to build it just clone/unpack this on your Sample directory from the DeckLink SDK and then issue "make". If you have Libav and pkg-config or pkgconf installed it will build fine.

Make sure you are using at least Libav10 otherwise it will not build.

You can build it out of the Sample tree by issuing

make SDK_PATH=/path/to/the/bmd/include

macOS Support

Should work out of box.

Windows Support

The tools do not build on Windows currently, supporting it would either require a working widl support in mingw64 or access to the native tools.

Patch and/or sponsorship welcome.

Usage

./bmdcapture -C 1 -m 2 -F nut -o strict=experimental:syncpoints=none -f pipe:1 | avconv -vsync passthrough -y -i - <your options here>

-C select the capture device if more than one is present.

-F define the container format, I suggest using nut.

-f output file name, any libavformat compatible url is supported.

-m specific modeline, resolution+framerate

-o pass AVFormat AVOptions (expert)

NOTE: make sure you are processing frames capture in real time or be prepared to end up using all your memory quite quickly, HD raw data fills up memory quickly.

avconv -vsync 1 -i <source> -c:v rawvideo -pix_fmt uyvy422 -c:a pcm_s16le -ar 48000 -f nut -f_strict experimental -syncpoints none - | ./bmdplay -f pipe:0

NOTE: The default NUT syncpoint strategy uses additional memory and could consume more memory than expected.

bmdtools's Issues

Latency issue possibly caused by avformat_find_stream_info

Live streaming through Nginx to avconv to bmdplay to Quad SDI card.

Was getting 2x a latency value (5-6s). Once through avconv and once through bmdplay. I was able to almost eliminate the latency through avconv with explicitly setting framerate (since I know it) and also setting the max time that avformat_find_stream_info looks for stream information.

-r 30 -probesize 750000 -analyzeduration 750000

full command:

avconv -r 30 -max_delay 1000 -probesize 750000 -analyzeduration 750000 -fflags nobuffer -i rtmp://localhost:1935/AV2015Local/stream2 -f nut -strict experimental -c:v copy -c:a pcm_s16le - | /home/vidcontrol/Builds/'Blackmagic DeckLink SDK 10.4.1'/Linux/Samples/bmdtools-master/bmdplay -m 10 -C 1 -f pipe:0

I am looking for something similar in bmdplay. Even better, since my format is fixed (I control the encoding and the RTMP streaming), I would like to be able to provide all of these hints up front so that I can reduce start up latency through bmdplay.

In fact, there is a note in the libav code about doing just this

from libav/libavformat/avformat.h @ ln 1445

• @todo Let the user decide somehow what information is needed so that

  •   we do not waste time getting stuff the user does not need.
    

    _/
    int avformat_find_stream_info(AVFormatContext *ic, AVDictionary *_options);

avconv using avformat looks for these supplied by user

nb_audio_sample_rate
nb_audio_channels
nb_frame_rates
nb_frame_sizes
nb_frame_pix_fmts

then picks a codec (decoder) which will have it's own set of parameters and then uses avformat_find_stream_info to fill in the blanks.

In bmdplay I think it would be possible to set these after here:

378 avformat_find_stream_info(ic, NULL);

ic->max_delay = 1000;
ic->framerate = 30;
ic->flags |= AVFMT_FLAG_NOBUFFER;
ic->probesize = 750000;
ic->max_analyze_duration = 750000;
ic->fps_probe_size = ?????;
ic->strict_std_compliance = true;

Of course the right way to do this is through the command line args.

Am I on the right track?

add releases to bmdtools repo

Could you occasionally mark bmdtools with releases in git? https://github.com/lu-zero/bmdtools/releases Would make it a little easier to manage in homebrew (such as here: https://github.com/amiaopensource/homebrew-amiaos/blob/master/bmdtools.rb)

ASI Output

Hi community,

Is there a way to output ASI from Decklink Duo or Quad cards?
Afaik only SDI/HDI outputs are possible with rawvideo.

If output is formatted, can ASI out can be taken from SDI output port?

BR,
Zulu

Detailed Build Instructions missing

Hi all,

I don't know why but i can't install bmdtools correctly.
It says something is missing, apparently libavutil/time.h and i don't know how to fix it. I tried with an ubuntu and a debian but sill the same damn shit. I have ffmpeg, ffmbc, libav.
I just noticed that ffmbc use timer.h instead time.h

If somebody could help me.
Thanks a lot

enhancement request: support pcm_s24le capture

I was very happy to see decklink-ffmpeg add support for 10 bit video capture. Could support for 24 bit audio be added as well?

Support UltraStudio 3d

On Mac the audio timestamps reported aren't in sync with the video. Possibly it is a driver bug.

Unable to capture video in SD/PAL/Composite with a duo/quad decklink

Hello,
SDI capture works fine but I didn't manage to capture SD video :

./bmdcapture -C 0 -m 2 -V 1 -F nut -f pipe:1 | ffmpeg -y -i - -f v4l2 /dev/video10
...
Failed to set video input - result 80000001
pipe:: Invalid data found when processing input

the source seems ok (digtal camera tested on a beamer analog in) and this command works great with SDI video in 1080i with -m 8 -V 4

Issues with newer versions of DeckLink SDK?

I have been trying the last few hours to capture off of a Blackmagic Intensity Pro using bmdcapture.

I am linking against libav-9.3 and Decklink SDK 9.7

I am able to capture with MediaExpress just fine off of HDMI. However when I run this command:

./bmdcapture -m 13 -A 2 -V 3 -C 0 -n 10 -F nut -f test.nut
and in response get:
Frame received (#1) - No input signal detected - Frames dropped 1 - Total dropped 1
Frame received (#2) - No input signal detected - Frames dropped 2 - Total dropped 2
Frame received (#3) - No input signal detected - Frames dropped 3 - Total dropped 3
...

In looking at old issues and PRs, I noticed much older versions of DeckLink sdk being mentioned is 7.3 and 7.9 and wondering if that could be the source of the issue?

When no signal from input use image from file instead of color bars

Nice work with bmdtools. Not as a bug tracker but feature request:
Signal detection works quite nicely with basic decklink card and SDI signaling. It would be nice addition to color bars to load image from file and even update it if file is changed. One could create info screens without any graphics generator from SDI when signal is lost or just shutdown between some events.

Support ClosedCaption

The driver supports ancillary data and there is a pull request about it.

The pull request does the parsing inside bmdtools and tries to output a subtitle stream and a new codec id.

I'd go with a simpler approach and use a data stream and signal its contents as is done for MXF, this way would be possible easily preserve the data across processing and possibly play it back w/out needing additional code to assemble it.

The Decklink driver is using core foundation internally and CFString in the interface while the Linux version uses char* to deliver the same information.

Does anybody try capture 4K videos by bmdtools + ffmpeg?

I have a Decklink 4K Extreme, I use it capture 4K videos and at the same time encode it by ffmpeg, I founed this process can't reach 25 fps. My ffmpeg call libx264 to encode 4K videos, it will reach 85fps on my computer. So I wonder why i Capture by bmdtool and encode by ffmpeg only 13fps.
My command is :
bmdcapture -m 25 -F nut -f pipe:1 | ffmpeg -i - -vcodec libx264 -profile:v high422 -r 25 -f mpegts udp://239.1.1.1:1234

Ffmpeg instead of avconv.

Tested current version of ffmpeg instead of avconv - bmdtools compiling and working (atleast bmdcapture) with it. So i guess readme needs to be updated :)

in case of novideo, color bars does not work with 10 bit

With no video source on 8 bit color bars are shown, but the data is only in uyvy422 (see https://github.com/lu-zero/bmdtools/blob/master/bmdcapture.cpp#L407-L408). I propose adding a version for v210.

Memory usage with bmdplay specifically

I know there is a longish previous thread under "Memory Usage", but also noticed the libav / nut branch that thread refers to appears to no longer be in the repo.

I am seeing bmdplay grow in memory usage - playing a 720P stream over the course of about an hour, it grows to around 1.4 GB.

I know in the previous thread there was some conclusion that the nut container format was the culprit, but also the conclusion that you could not change that option in bmdplay (vs bmdcapture) since in that scenario, you are intputing the format into bmdplay and you can't just randomly try an alternate format.

SO, I wanted to ask: was there every a conclusion on bmdplay? were the changes in the nut / libav branch included in master eventually? anything to try or data I can send you with bmdplay and high memory usage?

Thanks!

Stopping Capture

Hi,
When trying to capture from DeckLink Quad from all 4 channels at once (4 bmdcapture processes) They all except one stop after couple of minutes.

I get "Stopping Capture" message from the bmdcapture.

I'm using Ubuntu 12.04.4 LTS with 10.3.1 SDK and latest version of bmdcapture.

Is this a known issue ? Is there any way to know what is stopping the capture ?

Possible pixel format issue - yuv8

Overview
When used with pixel format (-p) yuv8 or not supplied avconv sees the incoming raw video as rgb555le. This is causing me color issues when generating videos or images from our feed.

I have managed to get around this by using yuv10 - avconv then sees the stream as yuv422p10le.

I am using the latest bmdtools from the repository with the latest firmware, SDK and drivers from Blackmagic. On Ubuntu 14.04.

Hardware used

0:  /dev/blackmagic/io0 [DeckLink Mini Recorder]    0x45    OK

Command used

/usr/bin/bmdcapture -C 0 -m 11 -V 4 -p yuv8 -f pipe:1 -n 1 -F nut -o strict=experimental:syncpoints=none | /usr/local/bin/avconv -vsync passthrough -y -i - -f image2 - > test.jpg

avconv Output

When using yuv8:

Input #0, nut, from 'pipe:':
  Metadata:
    encoder         : Lavf55.12.0
  Duration: N/A, start: 0.000000, bitrate: N/A

    Stream #0.1: Audio: pcm_s16le, 48000 Hz, stereo, s16, 1536 kb/s

When using yuv10:

Input #0, nut, from 'pipe:':
  Metadata:
    encoder         : Lavf55.12.0
  Duration: N/A, start: 0.000000, bitrate: N/A

    Stream #0.1: Audio: pcm_s16le, 48000 Hz, stereo, s16, 1536 kb/s

provide option to select pattern on no video

During the recording of files on unstable analog sources, bmdcapture will insert a pattern if there is no video (since 5a844f9). In 8 bit it is a color bar pattern and in 10 bit it is uyvy422 data rendered in v210 so a green/purple partial frame pattern. When working with unstable analog sources there are times when no frame data is received in the middle of a recording and the pattern is used. I propose that the pattern be selectable with color bars as default but including an option for black. I think an inserted occasional black frame would be less distracting to the current way bmdcapture handles unstable signals. I'm attaching two examples of the current state.

building against a static binary

I'm currently working with a statically linked binary of ffmpeg and I'm attempting to make bmdtools and I'm getting hit with an odd linker issue on ubuntu 14.04 LTS. Are there any known issues with compiling against a static build or am I just not correctly pointing to the dependency locations?

Memory usage issue

I am trying to use bmdcapture to pipe to an instance of ffmpeg segmented streaming for 24/7 recording but I keep running into the same issue, running out of memory. The server it is running on has 6GB of ram but after about 2 and a half days the ram fills up completely and bmdcapture dies then the ram is cleared. I have confirmed that piping bmdcapture to /dev/null still fills up the ram.

Are there any suggestions?

FFMBC - Works with bmdcapture.

I had to compile gstreamer and ffmbc from source in order to get this to work correctly. I tried for a long time to get avconv and ffmpeg working, but they would drop capture after 5-10 mins of recording no matter what I did.

Change behavior on input change

So right now when the input gets dropped, it immediately switches to color bars. I know in the Mac and Windows software there is any option to change this to either black or the last frame of video. I'm not sure if the Linux SDK has something similar that could be tapped into to bring this about.

Decklink mini recorder and bmdcapture modes list

Hi!

The Decklink mini recorder don't have outputs and because of that the modes list fail to load with the IID_IDeckLinkOutput interface. Must be used the IID_IDeckLinkInput interface to this card work.

Something like this fix the code:

// Query the DeckLink for its configuration interface

// Test input modes
result = deckLink->QueryInterface(IID_IDeckLinkInput,
                                  (void **)&deckLinkOutput);
  if (result != S_OK) {
   fprintf(stderr,"Could not obtain the IDeckLinkInput interface - result = %08x\n",result);

   // Input modes test failed lets try the output modes test
   result = deckLink->QueryInterface(IID_IDeckLinkOutput,
                                  (void **)&deckLinkOutput);

   if (result != S_OK) {
    fprintf(stderr,"Could not obtain the IDeckLinkOutput interface - result = %08x\n",
        result);
goto bail;
  } else {
fprintf(stderr,"This card have video output(s) but not have video input(s). You can not use this card with the bmdcapture software.\n");
    goto bail;
  }
}

10th of June, BMD announced an additional card for DeckLink 4K Extreme 12G which supplies 4x3G SDI input. Link: https://www.blackmagicdesign.com/press/release/20150610-01

Does bmdtools supports live raw AV 4K 60fps capture over DeckLink 4K Extreme 12G ?

Memory leak (?) when capturing from certain sources

We're capturing video from phones using Blackmagic Intensity Pro cards and we've noticed that when capturing from a Samsung Galaxy Nexus, bmdcapture's memory usage will grow slowly (after 2 minutes of recording, it gets to about 1GB of resident memory usage).

In comparison, an iPhone 5 will sit at around 120MB of resident memory usage (it does seem to grow, but very slowly and we're talking maybe 1MB a minute).

Is there something with the Galaxy Nexus' HDMI output that would be causing this? They're both outputing at 720p 60 fps.
