  • Adjusting video length to fit audio length in FFmpeg

    8 avril 2015, par Spreadys

    This has been driving me mad !
    I have video.avi, a raw uncompressed video with a duration of 6mins
    I have audio.wav, a raw uncompressed audio with a duration of 9mins

    I need to mux these together, but map the timing information from the audio.
    Using Vsync 2 I would hope that video frames get duplicated in order to do this.

    My current (failed) attempt is

    ffmpeg -i video.avi -i audio.wav
    - c:v rawvideo -c:a copy
    - vsync 2 -map 0:0,1:0 -map 1:0,1:0
    newvideo.avi

    My understanding is that the -map first designates what file:stream, and this is followed by the file:stream to be used for timing information.

    I have attempted all my usual research methods in an attempt to avoid asking but it is still resulting in the avi container holding two streams with the video length unchanged.
    If anyone can shed some light on my errors, I would be very grateful....or if you need further info - please ask !

    Thanks
    David

    Any guidance on what other information may promote some suggestions to where i’m going wrong also appreciated.
    Thanks

  • Multiple backslashes are not shown in Video

    26 février 2019, par Sebastian

    I want wo insert the text \ \ \ \ \ \ ' in a video. I escaped it to this

    -loglevel debug -y -i "in.mp4" -vf "[in] drawtext=fontfile=C\\\:\\\\Windows\\\\Fonts\\\\ariblk.ttf: text=\\\\ \\\\ \\\\ \\\\ \\\\ \\\\ \\\': fontsize=32 [out]" "out.mp4"

    The paths are read correctly, but no backslash is shown in the video. If I double the backslashes to \\ \\ \\ \\ \\ \\ ' I get the result I want with \ \ \ \ \ \ '

    -loglevel debug -y -i "in.mp4" -vf "[in] drawtext=fontfile=C\\\:\\\\Windows\\\\Fonts\\\\ariblk.ttf: text=\\\\\\\\ \\\\\\\\ \\\\\\\\ \\\\\\\\ \\\\\\\\ \\\\\\\\ \\\': fontsize=16 [out]" "out.mp4"

    The example from ffmpeg works.

    Which escape rule do I neglect ?

    Edit :
    Escaping the text to

    text='\\\\ \\\\ \\\\ \\\\ \\\\ \\\\ \\\'': fontsize=32 [out]

    or

    text=\\\\\\\\\\\\\\\ \\\\\\\\\\\\\\\ \\\\\\\\\\\\\\\ \\\\\\\\\\\\\\\ \\\\\\\\\\\\\\\ \\\\\\\\\\\\\\\ \\\\\': fontsize=32 [out]

    leads to an output of

    \ \ \ \ \ \: fontsize=32 [out]
