  • Cross-compile FFMPEG for OSX10.6 on 10.8

    12 juillet 2013, par Seth

    I use static binaries of FFMPEG and X264 in a droplet application I use at work. I found a great script that greatly simplifies creating the static dependencies and compiling the programs themselves. I used to work on a 10.6.8 machine and as my other machines at work upgraded to 10.7 and 10.8, the old binary continued to work fine. However, I've recently upgraded to a new iMac with 10.8 and I've been wanting to update my ffmpeg to the latest 2.0 release.

    As such, I've been trying to figure out cross-compiling for older OSX platforms and I've been failing. I've downloaded the OSX 10.6 SDK and I've tried all the various arch and target flags I can find for all the various libraries, but I still keep getting "Illegal Instruction" errors when trying to run ffmpeg or x264 on 10.6.8.

    The entire code is at this repo : https://github.com/csparker247/ffmpeg-static It's really only using the build-crosscompile.sh script and env.source, though. Any and all help is greatly appreciated (even if you just link me to some suggested reading).

    EDIT : I didn't have much time earlier so I wasn't able to explain as much as I'd have liked. Here's the configure command I'm using for ffmpeg. It should give an idea of how I'm trying to cross-compile. Chances are I'm doing it very wrong.

    CFLAGS="-I$TARGET_DIR/include -mmacosx-version-min=10.6" LDFLAGS="-L$TARGET_DIR/lib -lm" ./configure --arch=x86_64 --target-os=darwin --sysroot=/SDKs/MacOSX.platform/MacOSX10.6.sdk --enable-cross-compile --cc=clang --prefix=${OUTPUT_DIR:-$TARGET_DIR} --extra-version=static --disable-debug --disable-shared --enable-static --extra-cflags=--static --disable-ffplay --disable-ffserver --disable-doc --enable-gpl --enable-pthreads --enable-postproc --enable-gray --enable-runtime-cpudetect --enable-libfdk-aac --enable-libmp3lame --enable-libtheora --enable-libvorbis --enable-libx264 --enable-libxvid --enable-bzlib --enable-zlib --enable-nonfree --enable-version3 --disable-devices

  • FFmpeg change pixel format to grayscale

    2 juillet 2019, par newt

    I have one input video file.
    After doing

    ffprobe input.mp4

    I get the following :

    Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'input.mp4':
    
  Metadata:
    
    major_brand     : mp42

      creation_time   : 2018-01-20T03:43:28.000000Z
    
      handler_name    : Alias Data Handler

    I am trying to change video pixel format to 8-bit single channel grayscale with the following command :

    ffmpeg -i input.mp4 -pix_fmt gray output.mp4

    Then I am checking

    ffprobe output.mp4

    And get

    Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'output.mp4':
    
  Metadata:
    
    major_brand     : isom
    
    minor_version   : 512
    
    compatible_brands: isomiso2avc1mp41
    
    encoder         : Lavf57.79.100
    
  Duration: 00:08:55.60, start: 0.000000, bitrate: 5589 kb/s
    
    Stream #0:0(eng): Video: h264 (High 4:4:4 Predictive) (avc1 / 0x31637661), yuvj444p(pc), 1920x1080, 5578 kb/s, 29.97 fps, 29.97 tbr, 30k tbn, 59.94 tbc (default)
    
    Metadata:
    
      handler_name    : VideoHandler
    
    Stream #0:1(eng): Audio: aac (LC) (mp4a / 0x6134706D), 48000 Hz, stereo, fltp, 2 kb/s (default)
    
    Metadata:
    
      handler_name    : SoundHandler

    So, as I can see, pixel format didn’t change to 8-bit single channel grayscale.

    How to do this ?
