• 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.

  


• Why does a command in my Bash-script return 0 even when it fails ? Python, Whisper, ffmpeg

  10 juin 2024, par d-b

  I have a bash script that executes whisper on all sound files in a directory. Whisper uses ffmpeg to decode sound files to a format it can handle. One of the files in the directory was corrupt and caused ffmpeg to fail. The first time I executed my script it returned 1 when it hit that file but when I try to reproduce the error it always returns 0.

  


  Here is the log from the first run when 1 was returned :

  When I try to reproduce the behaviour I have both tried to execute the script as well as just running the actual line of code from the command prompt. The actual script looks like this :

  


  if whisper "$file" >> "${directory}/../${transdir}/${name}.txt"; then
    whispersuccess=$?
    echo "exit code $whispersuccess"
else
    whispersuccess=$?
    echo "exit code: $whispersuccess"


  


  I want it to return ¬0 when something like this happens. How do I achieve this ?

  I'm trying to use FFmpeg through ffplay to display a capture card output as lossless as possible.

  


  My capture card is named "Live Gamer Ultra-Video"

  


  In OBS, the NV12, YV12, P010 and YUY2 lead to blurriness around text and fine pixels edges, but the XRGB one offer clear output. So I've tried to focus on this mode with FFmpeg as the default one lead to same blurriness seen in OBS.

  


  Running "ffmpeg -f dshow -list_options true -i video="Live Gamer Ultra-Video" show me this result
(i've only kept line with wanted resolution)

video=Live Gamer Ultra-Video: Immediate exit requested


  


  "unknown compression type 0xE436EB7D" is a pretty bad start but from https://trac.ffmpeg.org/ticket/6279 I could figured out it was just unproperly parsed RGB24 format

  


  But if I run a very simple "ffplay -f dshow -i video="Live Gamer Ultra-Video" -pixel_format rgb24"
I got this output

  How could I use rgb format with this capture card ?

  


  If not possible, any other format leading to proper output would be ok too.
I've tried parameters from this topic Capture full-range/lossless rgb frame from capture card that supports NV12 and YUYV output without any good result sadly.
