H265: Support HEVC over SRT.(#465) v6.0.20

[chundonglinlin]

When you experience hevc over srt, compile by ./configure --h265=on --srt=on, then run by ./objs/srs -c conf/srt.conf.

# SRT config.

I'm running into an issue where it works with libx265 but it doesn't work with Nvenc

WORKS
ffmpeg -re -fflags +genpts -f lavfi -i "testsrc=duration=65536:size=1920x1080:rate=30" -f lavfi -i "sine=frequency=1000:sample_rate=48000:duration=65536" -vcodec libx265 -b:v 5M -maxrate 5M -bufsize 10M -pix_fmt yuv420p -c:a aac -b:a 128k -pes_payload_size 0 -f mpegts 'srt://127.0.0.1:10080?streamid=#!::r=live/srt_h265,m=publish'

DOESN'T WORK
ffmpeg -re -fflags +genpts -f lavfi -i "testsrc=duration=65536:size=1920x1080:rate=30" -f lavfi -i "sine=frequency=1000:sample_rate=48000:duration=65536" -c:v hevc_nvenc -preset p1 -profile main -level 4.0 -b:v 5M -maxrate 5M -bufsize 10M -pix_fmt yuv420p -c:a aac -b:a 128k -pes_payload_size 0 -f mpegts 'srt://127.0.0.1:10080?streamid=#!::r=live/srt_h265,m=publish'

When I run ffprobe is exactly the same HEVC video but SRS cannot accept it

here are the logs

I'm using the same above SRT conf

Can you raise an issue for this question? I'll test the encoder hevc_nvenc and be compatible. @johan149

For sure, here is the new issue #3388

[pfzer]

Hello, I encountered an issue with using the Soshi encoding chip for HEVC streams. When using ffmpeg SRT to push to SRS6.0.55, the SRT to RTMP conversion is not working properly. When playing with ffplay, there is severe mosaic. You can find more information about this issue at #3604.
