    MediaSPIP uses HTML5 video and audio tags to play multimedia files, taking advantage of the latest W3C innovations supported by modern browsers.
    The MediaSPIP player used has been created specifically for MediaSPIP and can be easily adapted to fit in with a specific theme.
    For older browsers the Flowplayer flash fallback is used.

  • H.264 - Identify Access Units of an image

    7 décembre 2017, par ivan_filho

    I need to parse a H.264 stream to collect only NAL’s needed to form a complete image, of only one frame. I’m reading the H.264 standard, but it’s confuse and hard to read. I made some experiments but, did not worked. For example, i extracted an access unit with primary_pic_type == 0 containing only slice_type == 7 (I-Slice), it should give me a frame, but i tried to extract from ffmpeg, it did not work. But, when i append the next access_unit, containing only slice_type == 5 (P-Slice) it worked. Maybe i need to extract POC information, but i think not, because i only need extract one frame, but i’m not sure. Someone have some tip of how get only NAL’s i need to form one complete image ?

  • Revision 29071a418e : Fix invalid memory access on 2x downscale. The issue was discovered on bitstrea

    9 septembre 2014, par Alexander Voronov

    Changed Paths :
     Modify /vp9/common/vp9_reconinter.c



    Fix invalid memory access on 2x downscale.

    The issue was discovered on bitstream with 2x vertical downscale. For
    zero MVs, y_pad is set to 1 only when vertical convolution is
    required. The original code assumes that for y_step_q4 == 32 we don’t
    perform vertical convolution. But vp9_setup_scale_factors_for_frame()
    sets convolve functions so that when x_step and y_step are both not
    equal to 16, convolve in both directions is performed. And convolve()
    unconditionally subtracts one stride from source pointer when calls
    convolve_horiz(). This leads to invalid memory access.

  • How to access YUV planes from ratecontrol in x264 encoder

    31 décembre 2018, par shuch

    I need to get access to the YUV planes in x264 encoder on the encoding stage. I understand how to do it on the input stage (in raw.c), but I don’t succeed to do it in encoder.c or ratecontrol.c.

    Thanks
