Sorry, there is no sense in your code above.

  • You are sending video by signaling with both vp8 and h264 in rtpParameters. No way.
  • You are not setting any profile-level-id nor packetization-mode in h264 parameters. This is not how h264 works, sorry.
  • No idea which h264 (and with which parameters) you have enabled in the mediasoup Router.
  • You are then telling ffmpeg to encoder with libopus.

Sorry, too many wrong things. Please read the mediasoup and ffmpeg documentation instead of trying random things.

i remove some code in sever’s config.js.
parameters :
{
‘packetization-mode’ : 1,
‘profile-level-id’ : ‘4d0032’,
‘level-asymmetry-allowed’ : 1,
‘x-google-start-bitrate’ : 1000
}
then ffmpeg.sh can’t push ,but lost too much.

it is ok with server config.js:
{
kind : ‘video’,
mimeType : ‘video/h264’,
clockRate : 90000 ,
parameters :
{
‘packetization-mode’ : 1,
‘profile-level-id’ : ‘42c029’,
//‘level-asymmetry-allowed’ : 0,
‘x-google-start-bitrate’ : 2000000
}
}
