31c51f7441 avpacket: add a function for wrapping existing data as side data 2015-12-06 10:22:18 +01:00

b09ad37c83 h264: derive the delay from the level when it's not present 
Fall back to maximum DPB size if the level is unknown.

This should be more spec-compliant and does not depend on the caller
setting has_b_frames before opening the decoder.

The old behaviour, when the delay is supplied by the caller setting
has_b_frames, can still be obtained by setting strict_std_compliance
below normal.

792b9c9dfc h264: set frame_num in start_frame(), not decode_slice_header() 
That is a more appropriate place for it, since it is not allowed to
change between slices.

741b494fa8 h264: eliminate default_ref_list 
According to the spec, the reference list for a slice should be
constructed by first generating an initial (what we now call "default")
reference list and then optionally applying modifications to it.

Our code has an optimization where the initial reference list is
constructed for the first inter slice and then rebuilt for other slices
if needed. This, however, adds complexity to the code, requires an extra
2.5kB array in the codec context and there is no reason to think that it
has any positive effect on performance. Therefore, simplify the code by
generating the reference list from scratch for each slice.

a853388d2f hevc: change the stride of the MC buffer to be in bytes instead of elements 
Currently, the frame stride is passed in bytes, while the MC buffer size
is in int16_t elements, This can be confusing, so pass both strides in
bytes.

1f821750f0 hevcdsp: split the qpel functions by width instead of by the subpixel fraction 
This should allow for more efficient SIMD.

Keep the C versions as they are now, to allow the compiler to inline the
interpolation coefficients.
