    avcodec/parser : fill avctx dimensions if unset

    This allows the usage of codecs in builds that have a parser but no decoders
    
for remuxing scenarios with raw sources.

  • How can I split a series of clips from a video and then stitch them together without audio or video gaps ?

    16 avril 2020, par Dr. Cyber Sec

    I'm developing an application where I take a video and (1) split it up into a bunch of 1 second chunks. Then, I need to (2) stitch a subset of those chunks back together, resulting in a slice of the original video.

    &#xA;&#xA;

    For example, let's say I have an original, 10s clip. I split it up into 1s chunks for each second (a clip from 0s to 1s, a clip from 1s to 2s, etc.). I now need to stitch, say, seconds 2-4 together into one video.

    &#xA;&#xA;

    I'm currently attempting both steps using ffmpeg.

    &#xA;&#xA;

    For clip-cutting :

    &#xA;&#xA;

    ffmpeg -ss 33 -i video.ts -t 1 33to34.ts&#xA;

    &#xA;&#xA;

    This should seek to second 33 and output a 1s clip duration, yielding a video clip containing seconds 33-34 of the original video. I noticed that ffmpeg doesn't always seek accurately, so after following the instructions in this post, which says to manually add keyframes to the parts of the video you want to cut, I tried this :

    &#xA;&#xA;

    First, setting the keyframes :

    &#xA;&#xA;

    ffmpeg -i video.ts -force_key_frames 00:00:01.000,00:00:02.000,00:00:03.000,00:00:04.000 out.ts&#xA;

    &#xA;&#xA;

    And then cutting the clips as I did before with the new output clip.

    &#xA;&#xA;

    While this did get the videos to be exactly 1s long each, (which I wanted) there is a small gap (just a slight jitter) in audio when I combine the clips back together. I cannot have this, and am looking for a solution.

    &#xA;&#xA;

    Can anyone help me understand why this is happening and help me find a solution ? Thank you so much in advance.

    lavc/qsvenc : fill the padding area

    qsvenc makes a copy when the input in system memory is not padded as the
    
SDK requires, however the padding area is not filled with right data
