  • How to select compile parameter with custom need？

    19 février 2019, par Shucheng

    I need to compile a static FFmpeg on macOS and add this build to a Xcode project. If I download a full version from official website that is work. But this version size is huge, and I just need a few format to convert. So I need to compile by myself.

    I’ve tired to compile and it’s worked. But I am not sure how to select compile parameter.

    For instance, I need to convert : ogg,flac,opus,webm files to mp3 file with the minimum size. And my compile parameter :

      ./configure --enable-ffmpeg --enable-small  --enable-static --enable-protocol=file,http,https --enable-libvorbis \
    
  --enable-libopus --disable-ffplay --disable-ffprobe --enable-demuxer=mp3,mp4,webm_dash_manifest,opus,flac,ogg \
    
  --enable-decoder=mp3*,vp*,mpeg4*,opus,flac --enable-libmp3lame  --disable-autodetect --disable-network --enable-pthreads

    But it seems not to work, I can’t convert files. Error reason is dyld: Library not loaded: /usr/local/opt/lame/lib/libmp3lame.0.dylib.But I used parameter --enable-static.

    So what should I do ? If I need to support a format to convert, I need to care about which respect ? Thanks

  • how download m3u8 in chunks using ffmpeg ?

    9 mai 2020, par relidon

    I'm trying to convert m3u8 to mp4 and I found the following method that works

    



    ffmpeg -i 'https://....m3u8' -bsf:a aac_adtstoasc \
    -vcodec copy -c copy -crf 50 output.mp4


    



    The end result, however, is too big for me to drag into an external hard drive.

    



    I also tried writing directly to the hard drive /Volumes/2TR/output.mp4 but the end result is the same - the file is too big, the operation fails.

    



    I noticed that if I terminate the operation at any point, the output.mp4 file works perfectly, but that it's not the full video (perfect). If the video is one hour and I just want 30 minutes of it I can terminate the ffmpeg operation at that point.

    



    So I'm wondering whether there's a way for ffmpeg to download the contents in two parts, output-part1.mp4 and output-part2.mp4 ?
