  • Options for cross-platform video & audio playback with speed control [on hold]

    11 janvier 2016, par Jon Cook

    I’m looking for a component that will do the following :

    1. (Must) Playback most common video formats (e.g. mp4, wmv, AVCHD, F4V, swf, MKV, DIVX, Mov, Avi, MPEG-1, MPEG-2, flv, VOB, asf)
    2. (Should) Stream video
    3. (Must) Playback most common audio formats (e.g .mp3, wav, .m4a, .mid)
    4. (Should) Stream audio
    5. (Must) Slow-down/speed up video&audio
    6. (Must) Adjust pitch of video&audio
    7. (Should) Zoom in on video

    It needs to work on the following platforms :

    1. (Must) Mac
    2. (Must) iPad
    3. (Should) iPhone
    4. (Should) Android
    5. (Should) Windows

    I’m prepared to work with any language, tech stack, whatever, as long as it meets those requirements.

    Is there any such thing out there ?

    I’ve started looking around (have checked out http://ffmpeg.org/ and www.vitamio.org/) but I’m a bit overwhelmed - too many variables - hoping someone out there might have some hints ?

  • FFmpeg 3.0 vs 3.1.1 decoding speed is different for 1920x1280 (3.1.1 is slow)

    20 août 2016, par Hwangho Kim

    I’m now making video player with ffmpeg.

    I’ve been using ffmpeg 3.0 and I upgrade it to 3.1.1.

    For 1920x1280 video (30fps), 3.1.1 decoding speed is slow so video stopped frequently for local video but 3.0 has no problem.

    I’m now using same build script for those.https://github.com/kewlbear/FFmpeg-iOS-build-script

    What’s the problem ?

  • lavc/cbrt_tablegen : speed up tablegen

    lavc/cbrt_tablegen : speed up tablegen

    This exploits an approach based on the sieve of Eratosthenes, a popular
    
method for generating prime numbers.
    

    Tables are identical to previous ones.
    

    Tested with FATE with/without —enable-hardcoded-tables.
    

    Sample benchmark (Haswell, GNU/Linux+gcc) :
    
prev :
    
7860100 decicycles in cbrt_tableinit,       1 runs,      0 skips
    
7777490 decicycles in cbrt_tableinit,       2 runs,      0 skips
    
[...]
    
7582339 decicycles in cbrt_tableinit,     256 runs,      0 skips
    
7563556 decicycles in cbrt_tableinit,     512 runs,      0 skips
    

    new :
    
2099480 decicycles in cbrt_tableinit,       1 runs,      0 skips
    
2044470 decicycles in cbrt_tableinit,       2 runs,      0 skips
    
[...]
    
1796544 decicycles in cbrt_tableinit,     256 runs,      0 skips
    
1791631 decicycles in cbrt_tableinit,     512 runs,      0 skips
    

    Both small and large run count given as this is called once so small run
    
count may give a better picture, small numbers are fairly consistent,
    
and there is a consistent downward trend from small to large runs,
    
at which point it stabilizes to a new value.
