  • Why does ffmpeg output frames starting with 0001 instead of 0000 ? [closed]

    3 février 2020, par AMTQ

    I’m using ffmpeg to extract frames from a video. It all works well but something seems strange : The numbering of the output always starts with 0001 instead of 0000. Below a minimum working example, the output from the console and a picture of the generated frames. I’m using windows shell on Win10.

    ffmpeg -i P1390752.MP4 -vframes 4 frame%%04d.png

    Console output :

    C:\Users\xxxx>ffmpeg -i P1390752.MP4 -vframes 4 frame%04d.png

    What I tried so far :
    1) I restricted the output to 4 frames because otherwise it would take ages. But the problem remains the same when I remove the number of frames and extract the whole video. The problem persists when using a starting point with -ss and a duration.
    2) When I use jpg as output I get some warnings about depreceated pixel format, but the numbering issue remains.

    I can not get rid of the first two warnings concerning the keyframe, maybe this is related ?

  • How to concatenate 3 mp4 files using ffmpeg (facing error in resultant video) ?

    5 février 2021, par Mayank Thapliyal

    I have 3 videos of mp4 format. They have same resolution (640 X 1280) but other properties like frame rate etc are different. I want to join them back to back.So I gave a check on internet and I used the following method

    &#xA;

    :: Create File List&#xA;echo file file1.mp4 >  mylist.txt &#xA;echo file file2.mp4 >> mylist.txt&#xA;echo file file3.mp4 >> mylist.txt&#xA;&#xA;:: Concatenate Files&#xA;ffmpeg -f concat -i mylist.txt -c copy output.mp4&#xA;

    &#xA;

    But unfortunately it did not worked.In the resultant video, file1 part got freezed, and audio of whole video shifted (no idea how).And other methods are also not working properly

    &#xA;

    I just want to join them back to back.Any idea how to do it ?

    &#xA;

    Edit :- I gave a check on the output of the ffmpeg (using pause command in bat and discovered the following. Maybe it may help regarding the issue)

    &#xA;
