  • Converting avi to mp4 (use ffmpeg library) is very slow

    7 décembre 2012, par yAnTar

    I have task - convert any video from user to mp4 format.
    I use command

    ffmpeg -i $file -vcodec libx264 -vpre ultrafast -bt 500k -acodec libfaac -ab 56k -ac 2 -s 480x320 $outputFileMp4

    I try to change options bitrate, dimensions, but spped of converting is slow - 3 mbytes convert arround 90 seconds.

    If i convert avi to flv - no problem.

  • Build FFmpeg with libaom using MSYS

    21 février 2021, par Alexander Dyagilev

    I'm trying to build FFmpeg (version 4.3.1) with --enable-libaom for Windows using MSYS and Microsoft Visual C++.

    


    Configure script says : ERROR: aom >= 1.0.0 not found using pkg-config

    


    But I have libaom (built it from sources) and paths to it are specified :

    


    set INCLUDE=%INCLUDE%;%~dp0..\..\libaom-build\prebuilt\include;
set LIB=%LIB%;%~dp0..\..\libaom-build\prebuilt\windows\x64\lib;


    


    This is how I call the configuration script :

    


    ./configure --prefix=$PWD/../../prebuilt/windows/x64 --toolchain=msvc --extra-cflags="-MD" --arch=x64 --disable-x86asm --disable-iconv --disable-network \
--enable-filter=stereo3d --enable-libmp3lame --enable-libaom --enable-libdav1d \
--extra-cflags="-I$PWD/../../../zlib-build/prebuilt/include -I$PWD/../../../libpng-build/prebuilt/include -I$PWD/../../../lame-build/prebuilt/include -I$PWD/../../../libaom-build/prebuilt/include -I$PWD/../../../libdav1d-build/prebuilt/include" \
--extra-ldflags="-L$PWD/../../../lame-build/prebuilt/windows/x64/lib -L$PWD/../../../libaom-build/prebuilt/windows/x64/lib -L$PWD/../../../libdav1d-build/prebuilt/windows/x64/lib"
