Issues getting client-read-h264 example working

[raybjork]

First off, this library is awesome thanks for developing and maintaining it!

I have been trying to get the client-read-h264 demo up and running on my machine and am running into an issue finding the decoder from the avcodec library (C.avcode_find_decoder(C.AV_CODEC_ID_H264) is returning nil). I have followed the installation instructions suggested in the comment of main.go and am getting the program to compile, but I am wondering if there is an extra step I need to do to link the library.

Any advice would be greatly appreciated, and apologies if this is not the correct format for this type of question.

Hello, if avcode_find_decoder returns nil, it means that the H264 decoder is not installed correctly. Please make sure that

• you're using Debian buster or onwards, or Ubuntu 20.04 or onwards. I've tested instructions on both of them (apt install -y libavformat-dev libswscale-dev gcc pkg-config) and found no problems at all
• Alternatively, make sure that the H264 decoder is installed properly
• On macOS, ome user suggests to add avcodec_register_all() before avcodec_find_decoder(), it may work for you too https://stackoverflow.com/questions/4091340/ffmpeg-compilation-problem-avcodec-find-decoder-always-returns-null
