  • How to interpret ffmpeg -pix_fmts output ?

    11 août 2015, par RichAmberale

    Running ffmpeg -pix_fmts returns a list of formats. Snip :

    IO... yuv444p16be            3            48
    
..H.. vdpau_mpeg4            0             0
    
..H.. dxva2_vld              0             0
    
IO... rgb444le               3            12
    
IO... rgb444be               3            12
    
IO... bgr444le               3            12

    What do the I O and H on the right side mean ? What are the numbers in the 2 leftmost columns ?

  • vp9 : switch min_tile_cols location so it shifts up instead of down.

    14 septembre 2015, par Ronald S. Bultje
    vp9 : switch min_tile_cols location so it shifts up instead of down.

    This fixes cases where the shifted number is 64, but we shifted non-
    
zero numbers away in the shift. The change makes behaviour consistent
    
with libvpx.

  • mpegvideo : do not set current_picture_ptr in decoders

    1er décembre 2013, par Anton Khirnov
    mpegvideo : do not set current_picture_ptr in decoders

    This code was originally added in
    
5f1948111a4920ff74e31b4284ab0200f7938539 to h263 to set decoded frame
    
pts to some random numbers (removed in
    
a1c5cc429d99216406170eac7e8352860076d3e8) and then cargo culted to other
    
decoders.
    

    The code is left in h263dec for now, since some part of the decoder
    
(apparently OBMC) relies on the specific previous frame to be reused.
