  • Use nvidia hardware acceleration to merge webms with pngs in ffmpeg

    2 février, par Joshi234

    So I need to merge around 18000 webms with with pngs, however on software encoding it's really slow, so I'm trying to use hardware acceleration to make this faster.

    


    I tried a lot of different stuff but none of them seems to work and it gives me generic errors to what I couldn't find anything relavant.

    


    This is the most "succesful" try I had :
ffmpeg -hwaccel cuvid -c:v vp9_cuvid  -i lightray.webm -i card.png -filter_complex "[1]format=argb,colorchannelmixer=aa=0.35[ol];[0][ol]overlay" -colorspace 5 -c:a copy output.webm

    


    Which gives me this error :

    I'm by no means an expert in ffmpeg or in video encoding in general, so I have no idea what this is supposed to mean.

    These are the logs, ffmpeg pushes the stream in a different folder when tried manually.

    


      

    • I tried changing the location of my file outside of oneDrive to avoid any permission conflicts.
    • 


    • Manually checked if FFmpeg is correct with this command : C:\ffmpeg\bin\ffmpeg.exe -i rtmp://localhost/live/test -c:v copy -c:a aac -f hls -hls_time 2 -hls_list_size 5 -hls_flags delete_segments output/index.m3u8

  • FFmpeg av_dump_format showing incorrect output, but ffprobe displays correct metadata

    29 janvier, par グルグル

    I use ffmpeg 7.1 source build on windows and compilation configuration as follow :

    


    configuration:
  --toolchain=msvc
  --arch=x86_64
  --enable-x86asm
  --enable-asm
  --enable-shared
  --enable-w32threads
  --prefix=/D/build


    


    When I use av_dump_format to print metadata of test.mp3, it display the incorrect information.

    


    extern "C"&#xA;{&#xA;#include <libavformat></libavformat>avformat.h>&#xA;}&#xA;&#xA;int main()&#xA;{ &#xA;    av_log_set_level(AV_LOG_DEBUG);&#xA;&#xA;    auto url = "D:/music/test.mp3";&#xA;&#xA;    AVFormatContext* fmt;&#xA;    auto ret = avformat_open_input(&amp;fmt, url, nullptr, nullptr);&#xA;    if (ret &lt; 0)&#xA;    {&#xA;        av_log(nullptr, AV_LOG_ERROR, "Cannot open %s format : %s", url, av_err2str(ret));&#xA;        exit(EXIT_FAILURE);&#xA;    }&#xA;&#xA;    av_dump_format(fmt, 0, url, 0);&#xA;}&#xA;

    &#xA;

    output

    &#xA;

    &#xA;

    You can see the Stream info is useless.

    &#xA;

    But I use ffprobe which is built with same configuration to print metadata of test.mp3.

    &#xA;

    It's display normal.

    &#xA;

    Why is av_dump_format not correctly showing stream information ? How can I fix it ?
