• ffmpeg stops reading rtsp livestream after some seconds

  26 décembre 2020, par user3019668

  I'm trying to save locally a rtsp livestream with ffmpeg but it stops after a few seconds. It works smooth, but suddently it just stops, more or less always after 10-15 seconds.

  



  This is the command :

  



  ffmpeg -rtsp_transport tcp -i rtsp://xxx.xxx.xxx.xxx:554/test.sdp -c copy test.ts


  



  And this is the log. I tried with previous ffmpeg versions with the same result :

  Debug shows also "No more output streams to write to, finishing" when it stops.

  



  Could you help me, please ? I don't know what else to try... Thank you.

  Thanks in advance...

  


• FFMpeg Input link in1:v0 parameters (size > 640x352, SAR 0:1) do not match the corresponding output link in0:v0 > parameters [duplicate]

  I am using below command to concatenate videos-

  



  String command[] = {"-i",inputFile1AbsolutePath,"-i",inputFile2AbsolutePath .....,"-i",inputFileNAbsolutePath,"-filter_complex","[0:v0] [0:a0] [1:v1] [1:a1]...[N:vN] concat=n=N:v=1:a=1 [v] [a],"-map","[v]","-map","[a]", outputFileAbsolutePath};


  



  and got below error-

  Seeing this answer i tried using-

  



  [0:v]setsar=1[v0]; [0:a0] [1:v]setsar=1[v1]; [1:a1]


  



  but did not worked !

  



  How can i resolve this ?
