I currently have Nginx setup with nginx-rtmp-module and I use it to stream into the live application and then do some FFmpeg work on it into our hls application. My goal is to prepend the stream name to all FFmpeg's log output. In the past, I would just use unique log file names to solve this, but with Docker, it is easier to use a single file.
Here is an excerpt from the live application (non-working)
exec_push ffmpeg -i rtmp://127.0.0.1:1935/live/$name -f flv rtmp://127.0.0.1:1935/hls/$name -loglevel repeat+level+debug 2> > (sed -u "s/^/FFMPEG: [${name}] /g" >>/proc/1/fd/1);
When I use an RTMP connection url like:
rtmp://127.0.0.1/live/myTestName
My goal is to generate logs that look like:

Thank you for your help!
I received a .raw frame format (here is a sample) which contains the raw pixel values of a frame. And I've been told I can convert it to an image (.bmp or .png) using FFMpeg using following command. However, when trying, it doesn't work.
dd bs=16 dumpB4EncodeHLSAfterEncodeBuf1200IP_TS/dumpedYuv/image-1140.raw | ffmpeg -f rawvideo -video_size 2160 2160 -pixel_format nv12 -i - yuv.bmp
What is the problem? Is there any ways to avoid use of dd and purely do it from FFmpeg?
Here is the error:
dd: unrecognized operand ‘frame.raw’
Try 'dd --help' for more information.

Updated Answer
Now that we know the correct size and format, we can do the conversion easily with ImageMagick:
magick -depth 8 -size 1920x1080 rgb:frame.raw result.png
Or, as you wanted, with ffmpeg:
ffmpeg -y -f rawvideo -s 1920x1080 -pix_fmt rgb24 -i frame.raw image.bmp
Original Answer
You raw file is either not NV12 or not 2160x2160. NV12 uses 1.5 bytes per pixel, which would mean you should have
2160 * 2160 * 1.5 = 6,998,400 bytes
but you actually have 6,220,800 so there is something wrong with your information - either the file is incomplete, or it is not that format or it is not that size.
If it was NV12, the first 2160x2160 bytes would be the greyscale (or Luminance/Y) channel, but even if we get the first 2160x2160 bytes as greyscale and ignore any trailing colour information, it is still wrong:
head -c $((2160*2160)) frame.raw | magick -depth 8 -size 2160x2160 gray:- image.bmp
Please check and identify the provenance and characteristics of your raw data.
It is possible to play a video file via ffplay in Docker?
I have tried to build this docker:
Dockerfile:
FROM ubuntu:18.04
RUN apt-get update && apt-get install -y ffmpeg
After run this docker with a command:
docker run -v /demo:/demo ffmpeg-test bash -c "ffplay -i /demo/test.mp4"
I got ffplay logs without any player window.
What am I missing?

I'm trying to use mp4 format coding (fourcc=0x21) on OpenCV 3.2 without success. Probably I have a problem with my Ubuntu 18.04 setup but currently I'm running out of ideas how to fix it. First, I recompiled FFMPEG with x264 support. Than, recompiled OpenCV (with contrib and OPENCV_ENABLE_NONFREE=ON, WITH_FFMPEG=ON). It is still not working.
I cannot use fourcc different than 0x21. I mean.. I cannot use another codec.
Example:
>>> import cv2
>>> out = cv2.VideoWriter('output.mp4', 0x21, 20.0, (640,480))
OpenCV: FFMPEG: tag 0x00000021/'!???' is not found (format 'mp4 / (null)')'
However, this is working fine (other fourcc, codec):
>>> out = cv2.VideoWriter('output.mp4',0x31637661 , 20.0, (640,480))
OpenCV compiled with FFMPEG support (version 3.2), cmake config:

So, what is wrong in this streaming example, if I have no problem when I substitute streams to the files?
I create a mjpeg file using the same parameters 9i.e. file is an output insteadof stream)

And then I playback this mjpeg file with ffplay. The play back is correct, I see no errors or exceptions.

So, what is the configuration issue for ffserver, or may be it is a bug of the ffserver?
UPD. I have realized, that i fed file1.ffm instead of file.ffm; that caused some ffserver problem:

After i set a correct feed, i got another exception on ffmpeg side:

So, what is the problem now?
the short answer is: you can't do that, at least not in that way. ffserver decides the expected input format by looking at the feed output name. when it sees you sending the data to feed.ffm it assumes ffm data, and so when libavformat/utils.c routine avformat_open_input calls s->iformat->read_header(s), it uses the ffm_read_header routine in libavformat/ffmdec.c:
/* header */
tag = avio_rl32(pb);
if (tag == MKTAG('F', 'F', 'M', '2'))
return ffm2_read_header(s);
if (tag != MKTAG('F', 'F', 'M', '1')) {
ret = AVERROR_INVALIDDATA;
goto fail;
}
here is where it sees the <ff><d8><ff><e0> at the beginning of the JPEG data, sees it is not equal to FFM2 or FFM1, and fails with "Invalid data found when processing input", although that message is never shown.
I can't yet tell you the right way to do it, but at least now you know what is happening.
