problems with input audio and video files

[mpisat]

When I try .h264 video file and .opus audio, it crashes.
test video works, but not always, somehow Wowza don't like it. On the other hand Pion seems to like it as it worked well with https://github.com/Glimesh/broadcast-box

Is there any other way to use it? I'm on Debian 10 and would like to use it to stress test Wowza server with WebRTC (via WHIP)

I tried v4l option, where I published rawvideo from ffmpeg to v4l dummy adapter, but I can't do so for audio and with bad opus audio (Wowza don't like it), video publish is still unplayable in Wowza.

mkfifo video
mkfifo audio

ffmpeg4 -y -re -stream_loop -1 -i /root/bbb/bbb_720p_2.5mbps_aac.mp4 -c:v copy -an -f rawvideo video
ffmpeg4 -y -re -i /root/bbb/bbb_720p_2.5mbps_aac.mp4 -c:a copy -f s16le audio

and then

whip-go -a audio -t "murathai" -v video -vc h264 -b 2500000 https://sg.karsiyaka.com/api/whip (Glimesh/Broadcast-box)

It can't play video.

if I use test for audio and test for video, it works somehow, but it is not accepted by Wowza (but accepted by glimesh/broadcast-box)

On the other hand, the following works just fine on glimesh/broadcast-box

ffmpeg4 -y -re -f lavfi -i testsrc2=s=1280x720:r=30 -f rawvideo video
ffmpeg4 -y -re -f lavfi -i sine=r=44100 -f s16le audio

but not this one:
ffmpeg4 -y -re -stream_loop -1 -i /root/bbb/bbb_720p_2.5mbps_aac.mp4 -c:v libx264 -b:v 1200k -x264-params "nal-hrd=cbr" -bufsize 1500k -preset veryfast -r 30 -tune zerolatency -g 30 -keyint_min 30 -an -f flv video
ffmpeg4 -y -re -i /root/bbb/bbb_720p_2.5mbps_aac.mp4 -c:a libopus -strict experimental -f opus audio

or this one:

ffmpeg4 -y -re -stream_loop -1 -i /root/bbb/bbb_720p_2.5mbps_aac.mp4 -c:v copy -an -f rawvideo video
ffmpeg4 -y -re -i /root/bbb/bbb_720p_2.5mbps_aac.mp4 -c:a copy -f s16le audio
