• avformat/mxfdec : use both body_sid and track_number to find the track of a packet

  6 février 2018, par Marton Balint

  avformat/mxfdec : use both body_sid and track_number to find the track of a packet
  In order to do that we have to parse the EssenceContainerData and assign the
  
  proper body_sid and index_sid to the tracks from the corresponding source
  
  packages.
  This fixes packets returned in the wrong stream for some OP1-b files.
  Based on a patch by Alex Mogurenko from https://github.com/da8eat/FFmpeg

• Error adding text on video using ffmpeg

  7 mars 2018, par robert tamunoemi

  Am trying to add text on video using ffmpeg. Everything works well if there is no spacing in the words. Here is my code

  $text = "Robert Tamunoemi";
  
  $cmd = 'ffmpeg -i '.$videoPath.'  -vcodec libx264 -f mp4 -vf drawtext="fontfile=fonts/futura-normal.ttf:text="'.$text.'":fontcolor=black@1.0:fontsize=14:x=00: y=40" -preset medium  videos/birds.mp4';
  
  
  
  shell_exec($cmd.' 2> log.txt');

  Here is the output from ffmpeg log

• 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.
