I am trying to decode a camera rtsp stream with ffmpeg_libs within a ubuntu docker container. The ffmpeg debug output seems to show (Docker Run Log) that it receives an SPS (nalu 7) and PPS (nalu 8), but nothing after that. It times out, retries, etc. That doesn’t really make sense to me.
The same code compiled and run locally seems to work OK (Local Run Log). After receiving the SPS and PPS, it then finds an IDR (nalu 5) and subsequent coded pics (nalu 1).
BTW, if I decode a file, the code works fine both locally and in docker container. So, the basic ffmpeg_lib decode is working. The difficulty is with the stream interface.
The camera uses digest authentication. Perhaps, authentication through the docker interface, or maybe port access, or something is the issue? I’m not much of a networking guy, so I’m really lost at this point.
The ffmpeg logs are below (I hope they aren’t too long. I put in drop down Summary blocks), and my docker run command is:
docker run -it --name VideoRx videorx:latest (I’ve also tried with -p 554)
Any help will be very much appreciated.
Thanks,
Wayne
