  • Display YUV/RGB frames on FFPLAY window

    22 novembre 2013, par Zax

    I have integrated a custom decoder on FFMPEG framework. The output of this decoder is YUV420 frames, which if required i can convert it to RGB24 frames.

    These frames are generated in one of my custom functions. So in order to render these frames on FFPLAY window what has to be done ? Is there any specific syntax or procedure to follow ?

    I'm really new to FFPLAY and have searched enough over this topic on net, but have not got anything related to this issue. If anyone can provide any answers or suggestions regarding this, it will be of great help to me.

    Thanks in advance.

    —Regards

  • matroskaenc : write correct Display{Width, Height} in stereo encoding

    matroskaenc : write correct DisplayWidth, Height in stereo encoding

    should be the raw amount of pixels (for example 3840x1080 for full HD side by
    
side) and the DisplayWidth/Height in pixels should be the amount of pixels for
    
one plane (1920x1080 for that full HD stream)."
    

    So, move the aspect ratio check in the mkv_write_stereo_mode() function
    
and always write the embl when stereo format and/or aspect ration is set.
    
Also add a few comments to that function.

    avcodec/h264 : Partially decode and display single fields try #2

    This like the previous attempt does not fully correctly decode this
    
type of non standard H.264, but it now works fully automatic
    
requiring no manual filters or flags to be used
    

    See Ticket2254
