Expected behavior A stream with lower resolution transcoded and stream to srs server
Additional context There even have no ./objs/ffmpeg-encoder-defaultVhost-live-stream-ff.log generated, i can do nothing on debugging I have send these information to LLM Deepseek for help, it provides meaningless solution. I have enough memory and cpu cores on my computer surely. If i try to run command ./objs/ffmpeg/bin/ffmpeg, it is work. Therefore, I think the problem is occured during compiling or just a important BUG
