• 'unsupported input sample rate set' error while converting mkv to mp3 with ffmpeg on python

  15 décembre 2020, par Agent Merlot

  I'm getting this error on trying to convert some mkv files to mp3 via python. Nearly all files got converted, but some are facing this issue.

• FFMPEG split mp3 and add metatag [closed]

  4 mai 2023, par Ghile

  I have a 2 hour mp3 that I automatically split with python3 and ffmpeg into many mp3 files. I would also like to add metadata to mp3 files, in order to have title, artist, year and album.

  


  In a csv file I have the cutting times and the name of the mp3 file, but I can't add meta data. The function I use is this :

  


  ffmpeg -loglevel panic -i 1.mp3 -ss 02:29:11 -to 02:34:43 -c copy -metadata 'title=My Title', 'artist=ME', 'date=2023' temp/myfile1.mp3


  


  Not work, It only works if I set the title only. Can you help me, please ?
Thank you,

  


• 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 &

  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.
