  • 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.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • FFmpegFrameRecorder calls record() 20 times but the resulting mp4 file only has 2 frames

    8 janvier 2015, par Long_Le

    I’m using FFmpegFrameRecorder to create mp4(H264) video from camera preview. My recorder configuration is as follows.

    recorder = new FFmpegFrameRecorder(filePath, width, height);
    
recorder.setVideoCodec(avcodec.AV_CODEC_ID_H264);
    
recorder.setFormat("mp4");
    
recorder.setFrameRate(VIDEO_FPS);
    
recorder.setVideoBitrate(16384);
    
recorder.setPixelFormat(avutil.AV_PIX_FMT_YUV420P);

    For the rest I follows closely to the sample code RecordActivity.java and was able to verify that

    recorder.record(yuvIplimage)

    gets called 20 (or more) times, which should create an mp4 with 20 frames. However, the resulting mp4 files after open up only has 2 frames (two first frame of the preview) ! I have no idea what have caused such behavior. Any help would be greatly appreciate. Thank you.

    Inline vp9_quantize() in xform_quant().

    Cycle times :
    4x4 : 151 to 131 cycles (15% faster)
    8x8 : 334 to 306 cycles (9% faster)
    16x16 : 1401 to 1368 cycles (2.5% faster)
    32x32 : 7403 to 7367 cycles (0.5% faster)

    Total encode time of first 50 frames of bus @ 1500kbps (speed 0)
    goes from 1min39.2 to 1min38.6, i.e. a 0.67% overall speedup.
