  • How Opensl es on android control the audio speed ?

    6 décembre 2013, par user1882379

    I use NDK+FFMPEG on android to decode an video file, and transfer the decoded pcm data to opensles for play audio .I register the opengles for the pcm format：

      SLDataFormat_PCM format_pcm;
    
    format_pcm.formatType = SL_DATAFORMAT_PCM;
    
    format_pcm.numChannels = channel;
    
    format_pcm.samplesPerSec = rate * 1000;
    
    format_pcm.bitsPerSample = SL_PCMSAMPLEFORMAT_FIXED_16;
    
    format_pcm.containerSize = SL_PCMSAMPLEFORMAT_FIXED_16;

    also I convert the decoded pcm data to AV_SAMPLE_FMT_S16 format using swr_convert(...), but the play audio speed is very fast. but if you use sdl , the play speed is normal. It would be sdl can control the play audio speed, but opensles can not. I do not know whether it is my mistake using opensles or opensles can not control audio speed(need application to control)？

  • Revision 6253cc9279 : Speed setting review. Substantial reworking of the speed vs quality trade offs

    1er octobre 2013, par Paul Wilkins

    Changed Paths :
     Modify /vp9/encoder/vp9_encodeframe.c


     Modify /vp9/encoder/vp9_onyx_if.c


     Modify /vp9/encoder/vp9_onyx_int.h


     Modify /vp9/encoder/vp9_rdopt.c



    Speed setting review.

    Substantial reworking of the speed vs quality trade offs for
    speed 1 and 2.

    In this patch I am attempting to freeze the "quality" meaning of
    speeds 1 and 2 relative to speed 0 so that in future we can
    better evaluate progress.

    I am targeting :
    Speed 1 quality -5% vs speed 0.
    Speed 2 quality -10% vs speed 0

    It is inevitable that quality will still fluctuate a little as we adjust
    settings and add new features, but we will attempt to keep as
    close as possible to these values. Above speed 2 things will remain
    a bit more fluid for now.

    In this patch speed 1 is approximately 4-5x as fast as speed 0. This
    is similar to before but the quality hit is a lot less. Likewise speed 2
    is approximately 2x as fast as speed 1 but is similar in quality to the
    previous speed 1 configuration.

    Also slight change to behavior of FLAG_EARLY_TERMINATE to insure
    all reference frames get at least one rd test. Important for very low
    variance regions.

    WIP :- Added a new speed level with old speed 4 becoming speed 5.
    Speed 3 and 4 tradeoffs still WIP
