    Moved call to vp9_clear_system_state() to a proper location

    The commit moved a call to vp9_clear_system_state() to a correct
    location, i.e. prior function calls using floating point numbers.
    This was to fix a mismatch mmx code and sse2 version, where a
    floating point number used in adjust_frame_rate(cpi) gets NAN due
    to mmx registers being in wrong state.

  • rtmpproto : Pass the ’live’ parameter in the right unit

    rtmpproto : Pass the ’live’ parameter in the right unit

    The current magic numbers passed are values in seconds, while the
    
parameter itself should be passed over the wire in milliseconds.
    

    This makes (some/all ?) live streams from Red5 work correctly, that
    
previously returned StreamNotFound even with "-rtmp_live live". After
    
this commit, the default ’any’ also works on these streams.

  • Showing a video using C (not C++ or C#)

    1er octobre 2013, par user2833591

    I learned programming in C using the Tscope-library (which is incompatible with C++ and C#), so I'm completely stuck with C.

    The Tscope-library is used to program small psychological experiments, it allows for functions that generate random numbers or produce images on the screen. Not sure if it might be a problem, but Tscope does generate it's own 'window'.

    So I wanted my experiment to show videos (currently in .wmv-format, but that can be changed, no problem), but I don't know how to do so (neither in code nor concept).

    I have come across FFmpeg, but the longer I see its code, the more I worry it's not meant for C (as in, parts of the code appear completely unknown to me). Could someone please help me ? If FFmpeg is indeed the answer, could someone give a quick run-down of the idea behind how it works (I've seen something about frames being put together) ?
