  • Can't figure out how to get ffmpeg to save to an odd file extension

    30 septembre 2015, par dinki

    I’m working on a network encoder for SageTV. I get request from the SageTV with certain filenames. I’m trying to capture video from my capture card and write out to a file called

    ’D :\Media\tvrecordings\RokuNetworkEncoderonlocalhost4510TVTuner-
    0.mpgbuf’

    Here’s the command I’m using :

    C :\Users\User>C :/Users/User/Desktop/ffmpeg-20150928-git-235381e-win64-static/bin/ffmpeg.exe
    -f dshow -crossbar_video_input_pin_number 2 -i video="ATI AVStream Analog Capture"
    D :\Media\tvrecordings\RokuNetworkEncoderonlocalhost4510TVTuner-0.mpgbuf

    When I run that command, I get this error :

    [NULL @ 00000000087f9160] Unable to find a suitable output format for 'D:\Media\
    
tvrecordings\RokuNetworkEncoderonlocalhost4510TVTuner-0.mpgbuf'
    
D:\Media\tvrecordings\RokuNetworkEncoderonlocalhost4510TVTuner-0.mpgbuf: Invalid
    
 argument

    But if I change .mpgbuf to .mpg it works fine . I am forced to use that filename though. Is there an easy way to do this ?

  • FFMpeg sync timecode with smpte ltc timecode audio signal

    11 avril 2018, par Olivier Rivard

    I’m trying to capture video from a capture card and I’m extracting 30 jpeg per second.

    I will have multiple computer capturing multiple cameras. I want to sync all those camera with a smpte ltc timecode audio signal pass in the audio line in of the camera.

    What would be the best way to set the timecode with that audio timecode using ffmpeg ?

    Here is the command I have which is sync with the timestamp, but sometime some cameras are out of sync because of the clock of the computer :

    ffmpeg -vsync 0 -f dshow -rtbufsize 1500M -video_size 1920x1080 -use_wallclock_as_timestamps 1 -copyts -r 30 -i video="QP0203 PCI, Analog 01 Capture" -r 30 -vf setpts=PTS-STARTPTS -vsync 0 -vframes 1800 name%d.jpeg -c copy -vsync 0 -vframes 1800 -f mkvtimestamp_v2 file.txt
