  • avcodec/prores_aw : add support for prores 444 with alpha

    8 novembre 2018, par Martin Vignali
    avcodec/prores_aw : add support for prores 444 with alpha

    only 16b alpha is supported (not 8 bits)
    

    following official encoder, alpha data doesn't impact
    
yuv plane quality.
    

    So the alpha data encoding is done after the yuv part.
    
It's also avoid to loose quality in yuv part when
    
alpha is not uniform.
    

    the alpha encoding funcs is mainly take from prores_ks
    
encoder, except for the alpha data reorganization

  • How to build ffmpeg as a Position independent executable (PIE) or PIC on Android ?

    22 avril 2016, par Parth Doshi

    I have checked out the latest source of ffmpeg from the official website. I now want to compile and build ffmpeg as a position independent executable.

    Here is what my configure command looks like

    ./configure --prefix=/usr/local --enable-gpl --enable-pic --enable-nonfree --enable-libass --enable-libfdk-aac --enable-libfreetype --enable-libmp3lame --enable-libopus --enable-libtheora --enable-libvorbis --enable-libvpx --enable-libx264 --enable-libx265

    I have added the option --enable-pic to make it a PIE. However when the build process completes successfully and when I do a hardening check as follows then I get below output

    hardening-check ffmpeg

    ffmpeg:
    
Position Independent Executable: no, normal executable!
    
Stack protected: yes
    
Fortify Source functions: yes (some protected functions found)
    
Read-only relocations: yes
    
Immediate binding: no, not found!

    This tells me that ffmpeg is still not a PIE. Can anyone tell me what am I missing here ? Is there any other changes that need to be done for adding PIE support.

  • How to fix this FFMPEG command to record audio as well ?

    19 mai 2018, par James Kowalski

    I am trying to fix this FFMPEG command to record audio.

    I have tried using the parts recommended on the official stackoverflow site but they didn’t work

    Orignal Command

    ffmpeg_stream = '/usr/bin/ffmpeg -f x11grab -s 1280x720 -r 24 -i :%d+nomouse -c:v libx264 -preset superfast -pix_fmt yuv420p -s 1280x720 -threads 0 -f flv "%s"' % (xvfb.new_display, info['destination'])

    Command with attempted audio

    ffmpeg_stream = '/usr/bin/ffmpeg -f x11grab -s 1280x720 -r 24 -i :%d+nomouse -c:v libx264 -preset superfast -pix_fmt yuv420p -s 1280x720 -threads 0 -f alsa -ac 2 -i hw:0 -f flv "%s"' % (xvfb.new_display, info['destination'])
