ffmpeg record error about mediasoup3-record-demo HOT 5 CLOSED

Hello,

Could you tried adding "-analyzeduration 2147483647 -probesize 2147483647" to the beginning of the ffmpeg command args.

from mediasoup3-record-demo.

hi
I add the -analyzeduration and -probesize option into the ffmpeg.js

  get _commandArgs () {
    let commandArgs = [
      '-analyzeduration',
      '2147483647',
      '-probesize',
      '2147483647',
      '-loglevel',
      'debug',
      '-protocol_whitelist',
      'pipe,udp,rtp',
      '-fflags',
      '+genpts',
      '-f',
      'sdp',
      '-i',
      'pipe:0'
    ];

and the error is also:

It looks like it's not reading the vp8 track correctly, have you changed the mediasoup config file?
Also could you check the mediasoup debug logs?

from mediasoup3-record-demo.

hi,I found the error.
the error is i change the webRtcTransport ip to "0.0.0.0",
when update it to the local ip , that is ok!

Thanks!
