  • diracdec : fix idwt_stride calculation in bytes

    diracdec : fix idwt_stride calculation in bytes

    The transformation to bytes must happen after alignment to get the same
    
resulting pointers as before.
    

    This fixes segmentation faults in the assembler code.
    

    The regression was introduced in commit 9553689.

    avformat/dashdec : Avoid segfault when URL template is unexpectedly missing

    This isn't supposed to happen, but unfinished support for non-templated
    
manifests and lack of e.g. presentationTimeOffset handling can provoke
    
such a situation even with well-formed input.

  • How to "mimic" -c copy when using filters with ffmpeg ? Is there a built-in feature or I'll need some scripting ? [closed]

    29 décembre 2023, par Fabio Freitas

    I'm aware that any stream ffmpeg processes is decoded before applying any desired changes and then re-encoded, which means the stream in question can't simply be copied with -c copy.

    &#xA;

    Still, I'm not yet very knowledgeable on dealing with media files. Currently, the single issue I'm addressing is cropping black bars from the sides when 4:3 is encoded as 16:9.

    &#xA;

    That's fairly simple, and I quickly managed to get it going.

    &#xA;

    Then I noticed some weird stuff via mediainfo and the explorer's side panel. Stream sizes, bitrates and some other details were different than expected.

    &#xA;

    &#xA;

    That's where -c copy comes in. Over the years, every time I tried to solve this, answers would stop at "-c copy can't be used if the stream will be decoded", which is good enough to stop noobs like me from wasting time.

    &#xA;

    But since I don't know how to use advanced encoding settings, the -c copy I'm looking for is actually how can I re-encode my processed stream using the same (or most similar) settings used before I decoded it.

    &#xA;

    Is there such an option in ffmpeg ? Are these settings I'm looking for even obtainable by any means ? And if "no" and "yes", could I use ffprobe to write a script for ffmpeg ?

    &#xA;

    BTW, I'm on Windows 11, but I have Git's SCM tools available.

    &#xA;
