  • How to concatenate two videos w. ffmpeg — documented code not working

    2 mars 2014, par Jim Miller

    I'm trying to concatenate two videos with ffmpeg. Nothing fancy ; I just want one video that consists of video A immediately followed by video B.

    I've tried the code from How to concatenate (join, merge) media files on a freshly built and otherwise-working-fine install of ffmpeg 1.2.1 on Fedora 17, but the following error message appears :

    $ ffmpeg -i video_a.mov -i video_b.mov -filter_complex '[0:0] [0:1] [1:0] [1:1] concat=n=2:v=1:a=1 [v] [a]' -map '[v]' -map '[a]' output.mp4

Stream specifier ':0' in filtergraph description [0:0] [0:1] [1:0] [1:1] concat=n=2:v=1:a=1 [v] [a] matches no streams.

    A few other things to note :

    • The two videos I'm working with were shot with the same camera, so there shouldn't be any problems with aspect ratio or other gory video details.
    • I'm able to do other things with my ffmpeg installation, like convert one of those videos from .mov to .mp4 (yes, I had to recompile with faac...), which seems to vouch for both the ffmpeg and the video.
    • I've tried modifying the above invocation to produce a .mov file at the end, but I get the same error as before.
    • I've tried some stupid hacking tricks on the request above, like concatenating two copies of the same video, as well as some other invocations from other places around the web that involve filter_complex. Even on ones that were cited as working, I get the "matches no streams" message.

  • ffmpeg audio video synchronisation mux

    I am trying to mux audio and video but the resultant is not what expected. The video is not shown in the output.
