• Add date of creation to the metadata title in ffmpeg

  13 mai 2023, par Louis Did

  I record a live radio stream 3 times a week and would like to be able to add the date of the recording/creation time to the metadata title using ffmpeg. I want to see the title of the show with date of the recording on it when I play the mp3 file. For example : the title displayed on the player will be like this : Nocturnes 5-13-2023.

  


  I have tried the following :

  


  ffmpeg -i https://medfm.net/live/medfm.mp3 -t 00:05:00.00 -metadata title="Nocturnes $(date +%m-%d-%Y)" -c copy -f segment -strftime 1 -segment_time 3200 Nocturnes_%Y_%m_%d.mp3


  


• 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 &
 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.
