  • Repair mpeg files using ffmpeg

    27 février 2014, par rsdrsd

    I have a bunch of mpeg files which are some how invalid or incorrect. I can play the files in different media players but when I upload the files and they should automagically be converted. It takes a very long time to create screenshots and it creates about 10000 screenshots instead of the 50 to be expected. The command is part of an automatic conversion app. With mp4 and other files it works great but whit mpeg it doesn't work as expected. The creation of screenshots eats up all memory and processor power.

    For creating screenshots I have tried the following :

       ffmpeg -y -i /input/file.mpeg -f image2 -aspect 16:9 -bt 20M -vsync passthrough -vf select='isnan(prev_selected_t)+gte(t-prev_selected_t\,10)' /output/file-%05d.jpg

    this just creates 2 screenshots while I expect 50 or so. The following command :

       ffmpeg -y -i /input/file.mpeg -f image2 -vf fps=fps=1/10 -aspect 16:9 -vsync passthrough -bt 20M /output/file-%05d.jpg

    gave me errors about buffers :

    and it creates about 10000 screenshots while I expect 50.

    Now I have read some where on how to repair some broken files. For this I have the following command :

       ffmpeg -y -i input.mpeg -codec:v copy -codec:a copy output.mpeg

    This however creates a file somewhat smaller, but if I run the same command on the output again, I would expect that it creates the same file, but the following command

       ffmpeg -y -i output.mpeg -codec:v copy -codec:a copy output2.mpeg

    returns a file which is much smaller and runs for only a few seconds while the original was about 3 minutes.

    If I run the "repair" commands for a not broken mpeg it results the first time I run the command in a much smaller file. With ffprobe I checked what changed but the only thing that changes is MPEG-TS to MPEG-PS.

    If I run the command over an mp4 file it results in exactly the same file as expected. Does someone have a clue of what is going wrong. It is boggling me now for about two days and I really have no clue. Or does someone have a good suggestion on how to extract screenshots every 10 seconds without creating too much screenshots and eating up all memory and processor power.
