• ffmpeg rtsp record problems [closed]

  3 mai 2023, par user429643

  I have 3 ip cameras from which I take rtsp stream and record mp4 files via ffmpeg. Previously, everything worked well, but some time ago, the recording from second camera ends after a some period of time (before it should be ended).
Program code :

  


  if [ "$1" = "1" ]; then
    ffmpeg -rtsp_transport tcp -use_wallclock_as_timestamps 1 -fflags +genpts -fflags -discardcorrupt -i rtsp://$CAMLogin@$CAM1IP:$RTSPport/Streaming/Channels/101 -r 20 -vcodec copy -an -t $RECtime -vsync vfr $FULLpath/1.mp4 -report null >/dev/null 2>$FULLpath/cam01.log &
    ffmpeg -i rtsp://$CAMLogin@$CAM1IP:$RTSPport/Streaming/Channels/101 -t 1 -vframes 1 -s 1280x720 -f image2 $FULLpath/1.jpg null >/dev/null 2>$FULLpath/cam_jpg01.log &
fi

if [ "$2" = "1" ]; then
    ffmpeg -rtsp_transport tcp -use_wallclock_as_timestamps 1 -fflags +genpts -fflags -discardcorrupt -i rtsp://$CAMLogin@$CAM2IP:$RTSPport/cam/realmonitor?channel=1&subtype=0 -r 20 -vcodec copy -an -t $RECtime -vsync vfr $FULLpath/2.mp4 -report null >/dev/null 2>$FULLpath/cam02.log &
    ffmpeg -i $CENTRAL -t 1 -vframes 1 -s 1280x720 -f image2 $FULLpath/2.jpg null >/dev/null 2>$FULLpath/cam_jpg02.log &
fi

if [ "$3" = "1" ]; then
 ffmpeg -rtsp_transport tcp -use_wallclock_as_timestamps 1 -fflags +genpts -fflags -discardcorrupt -i rtsp://$CAMLogin@$CAM3IP:$RTSPport/Streaming/Channels/101 -r 20 -vcodec copy -an -t $RECtime -vsync vfr $FULLpath/3.mp4 -report null >/dev/null 2>$FULLpath/cam03.log &
 ffmpeg -i rtsp://$CAMLogin@$CAM3IP:$RTSPport/Streaming/Channels/101 -t 1 -vframes 1 -s 1280x720 -f image2 $FULLpath/3.jpg null >/dev/null 2>$FULLpath/cam_jpg03.log &


  


  If I set a certain recording time, then the problem occurs only from the second camera.

  Initially, I thought that the error was in timestamps, so I added arguments to ffmpeg :

  


  -use_wallclock_as_timestamps 1
-fflags +genpts
-fflags -discardcorrupt
-vsync vfr

  


  But this doesnt help.

  


• avformat/aviobuf : Add ffio_init_(read|write)_context()

  2 septembre 2023, par Andreas Rheinhardt

  avformat/aviobuf : Add ffio_init_(read|write)_context()
  Most users of ffio_init_context() simply want to wrap
  
  a buffer into an AVIOContext ; they do not provide
  
  function pointers at all.
  Therefore this commit adds shortcuts for these two common
  
  operations. This also allows to accept const data when reading
  
  (i.e. the const is now cast away at a central place in
  
  ffio_init_read_context() instead of at several callers).
  
  This also allows to constify the data in ff_text_init_buf().

• FFmpeg cut a 16:9 video to a 9:16 ratio and put subtitle only in ratio [closed]

  8 septembre 2023, par LordzSpectron

  I want to cut a 16:9 video to take only the central part of it, vertical and what's left, fill it with black borders, example :

  


  

  


  I want only the part highlighted in red.

  


  How to make this using ffmpeg ?

  


  I've been trying using crop, some answers that taught how to blur what's left, but they all leave the full video and just cut it down to 9:16.

  


  I want to have only the middle part highlighted and the rest be black border.
