  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.

  • Processing yuv4mpeg by hand

    15 avril 2014, par user3534466

    Theoretical question.

    I have named pipe(windows) with uncompressed-video yuv4mpeg and uncompressed-audio pcm. I need to read this stream in my program and render it to bitmap.

    If I realy understood description of yuv4mpeg http://wiki.multimedia.cx/index.php?title=YUV4MPEG2, there are simple YCbCr-images after header.

    Is it simple way to processing and rendering this data by my own code C++ without any libraries (ffmpeg) ?

  • What's the difference with crf and qp in ffmpeg ?

    12 novembre 2024, par Nova

    I read https://trac.ffmpeg.org/wiki/Encode/H.264 about h264 encoding and discovered qp.

    


    Q1 : What are the differences with crf and qp ?
    
Q2 : Is it better to use qp over crf overall, or is it only if for using qp 0 for best lossless ?
    
Q3 : Does qp have a known sensible setting if it's preferred ? So far, I know crf has the default value of 23 while 18 is a sensible preferred increase in quality, although I don't understand why 18 wouldn't be default if better sensible lossless.
    
Q4 : Would changing either of them cause incompatibility with non-ffmpeg players or just qp ?

    


    I'm converting from webm to mp4.

    


    I was going to test crf 23 and 18 and pick which is best but I can't seem to find any concrete information on this comparison or about qp.
