  • How can I prettify my compiled binary of FFmpeg ?

    2 avril 2019, par Hashim

    After many weeks and a lot of effort, I finally managed to use a Cygwin and MinGW-w64 toolchain to cross-compile a working binary of FFmpeg for Windows, complete with the superior but elusive fdk_aac encoder.

    However, comparing my newly-compiled binary with the official pre-compiled build for Windows makes me feel a little... lacking (first run is the Zeranoe build, second is my own) :

    enter image description here

    Notice how the Zeranoe build’s banner is missing all of the unseemly-looking configure options apart from the external libraries. Along with that, it also has the date that the program was built on inserted right after the GCC version.

    How were the compilers of this build able to add these enhancements to their binary, and how can I do the same ? I’m assuming these are simply GCC or preprocessor options that I can’t find any information on, or maybe there’s more to it than that.

    N.B : I’m aware of the --no-banner switch for FFmpeg, and that’s not what I’m trying to do here.

  • Can't decode HEVC video with DXVA2 and ffmpeg

    10 mai 2018, par Igor

    I can’t use DXVA2 hardware acceleration for decoding of HEVC video with ffmpeg. DXVA2 for H.264 works fine.

    I compiled an official example hw_decode.c from ffmpeg sources :

    https://github.com/FFmpeg/FFmpeg/blob/master/doc/examples/hw_decode.c

    When I call av_send_packet() it performs a callback assigned in AVCodecContext->get_format and returns only AV_PIX_FMT_YUV420P for HEVC video instead of AV_PIX_FMT_DXVA2_VLD for all H.264 videos. So HW decoding doesn’t work.

    Software decoding of HEVC works without problems.

    MPC-HC plays fine HEVC video with DXVA2 (CPU loading is low and Task Manager shows work of Video decoder in GPU details). My video card is Geforce 1060.

  • Ffmpeg - avio_open returns AVERROR -13

    10 septembre 2021, par Tolga

    In my project, I am trying to save mp4 video from frames. I am demuxing video first and then decode and save the .mp4 file beside frames. However, this mp4 file is only playable from command line with ffplay. I am trying to play it from media player. After little bit search I found that, I need to remux it to mp4 file after encoding. The examples that I reference for my project are official ffmpeg example and leandromoreira's code. However, avio_open() parts returns -13 as error. I printed out with av_make_error_string(error, sizeof(error), response) and got Permission denied. When I look for that error in the error.h
there is no such an error defined.
