I'm quite confused because It seems to be a incompatible question on ffmpeg, which AV_CODEC_CAP_TRUNCATED has been removed on ffmpeg 6.0, but I'm using ffmpeg 3.4.9 and I don't know how to fix that.
So the issue for me was that I had previously installed a newer version of ffmpeg (6.x) through a ppa and that required the newer version of libavcodec which caused this error. Once I uninstalled both and downgraded to ffmpeg 4.4.2 and libavcodec 58 (which I believe are the defaults for ubuntu 22.04?), the package compiled correctly. Had to remove the ppa, then sudo apt autoremove then sudo apt install ffmpeg. Check with ffmpeg -version and you can check the libavcodec you have installed with ls -l /usr/lib/x86_64-linux-gnu/libavcodec*
This is probably going to be fixed with https://github.com/DaWelter/h264decoder/pull/21.
