Register mmaldec as mpeg2 decoder. Supporting mpeg2 in mmaldec is just a
matter of setting the correct MMAL_ENCODING on the input port. To ease the
addition of further supported mmal codecs a macro is introduced to generate
the decoder and decoder class structs.

There is no avpriv_atomic_get, instead avpriv_atomic_int_get is to be used for
integers. This fixes building mmaldec.

And simplify and explain the expression.

It is always equal to nb_slice_ctx.
|

This is more correct and avoids wasting space when frame threading is
used.
|
| |
|
|
|
| |
This limit is now unnecessary, we can easily support an arbitrary number
of threads.
|
| |
|
|
| |
Those should already be set to the correct values.

In such a case, decode the MBs in parallel without the loop filter, then
execute the filter serially.
The ref2frm array was previously moved to H264SliceContext. That was
incorrect, since it applies to all the slices and should properly be in
H264Context (it did not actually break decoding, since this distinction
only becomes relevant with slice threading and deblocking_filter=1,
which was not implemented before this commit). The ref2frm array is thus
moved back to H264Context.

It is not used for anything internally, just exported in the output
frames. So remove the indirection and set it directly in frame_start().
|
| | |
|
| | |
|
| |
|
|
| |
It is no longer called from outside the h264 decoder.
|
| |
|
|
|
|
| |
It is always unconditionally initialized in decode_postinit() and then
immediately used in one place further below. All the other places where
it is accessed are just useless fluff.

It is very fragile against fields being moved and hides what is actually
being copied. Copy all the fields explicitly instead.

This will allow decoupling the parser from the decoder.

Make the SPS/PPS parsing independent of the H264Context, to allow
decoupling the parser from the decoder. The change is modelled after the
one done earlier for HEVC.
Move the dequant buffers to the PPS to avoid complex checks whether they
changed and an expensive copy for frame threads.

It is no longer needed for anything.

It has nothing to do with the reference count and so does not belong in
this function.

Remove now unused ff_h264_decode_nal().
|
| |
|
|
|

Just pass through the bitstream as is. This is the same as what is done
for HEVC already.

This muxer generally handles pts == NOPTS by using dts instead;
do this for consistency here as well.

This codepath isn't quite as bad as it used to sound, if fragments

And use it for the separate-plane side-feature as well.

Modifying global header extradata in encode_frame is an API violation
and only happens to work currently because mov writes its header
at the end of the file.

The h264/hevc Annex E colour primaries table says that AVCOL_SPC_SMPTE170M is
similar than AVCOL_SPC_SMPTE240M. These two values are not similar than
AVCOL_SPC_BT470BG.
