Could you record your rtmp stream to a file? then I can reproduce it.

1. close rtmp_to_rtc conf. (rtc.rtmp_to_rtc = off, then the srs wouldn't crash.).
2. record your rtmp stream by this cmd. (e.g. your stream is /live/livestream).
   ffmpeg -re -i rtmp://localhost/live/livestream -c copy -f flv output_video.flv.

aac.flv.zip

with rtc.rtmp_to_rtc = off , i confirm ossrs don't crash

#4227 can fix this issue. you can verify by yourself.

Cause

It's the Audio source's invalid data problem.
I play the above audio source, aac.flv.zip, with latest ffmpeg, version 7.1. The same error print in the console.
ffplay aac.flv
[aac @ 0x12ae95960] error in spectral data, ESC overflow

So if the ffplay can play the audio source, it's reasonable to let SRS audio transcode the ignore similar error without kickoff the stream.

Solution

#4227 , ignore AVERROR_INVALIDDATA, the invalid data error returned from avcodec api.
