Helps in decoupling this code from mpegvideo.
|
|
|
|
| |
It will be needed to initialize BlockDSP in the next commit.
|
|
|
|
|
| |
Use it instead of the embedded mpegvideo one. Update init function
signature to load it directly from the callers.

This avoids accessing NULL pointers in case of error.
|
|
|
|
|
| |
The deinit function in the 'error' section will correctly free
everything.

The profiles are a property of the codec, so it makes sense to export
them through AVCodecDescriptors, not just the codec implementations.

get_bits should not be used with more than 25 bits.

They are just duplicates of AVCodecContext members so use those instead.

If a seek is requested before the decoding start there is no
current picture.

This appears to be the intended behavior.

Initialise VC1DSPContext for parser as well as for decoder.
Note, the VC-1 code doesn't actually use the function pointer yet.

This way each decoder does not have to do the same thing manually.
|
|
|
|
| |
It will be useful in the following commits.

This caused mpv (and possibly others) to fallback to software decoding after
seeking a VC1 stream.

The most interesting parts are initialization in ff_MPV_common_init() and
uninitialization in ff_MPV_common_end().
ff_mpeg_unref_picture and ff_thread_release_buffer have additional NULL
checks for Picture.f, because these functions can be called on
uninitialized or partially initialized Pictures.
NULL pointer checks are added to ff_thread_release_buffer() stub function.

Several decoders disable those anyway and they are not measurably faster
on x86. They might be somewhat faster on other platforms due to missing
emu edge SIMD, but the gain is not large enough (and those decoders
relevant enough) to justify the added complexity.

Tables are always allocated now with sufficient space for either progressive
or interlaced content. The alternative would be to detect a change
and reallocate.
This fixes decoding of a sample.

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.
|
|
|
|
|
| |
This will allow removing the hacks where each decoder sets
current_picture_ptr on its own.
|
|
|
|
|
|
|
| |
Happens on a B-frame when neither low_delay nor last_picture_ptr is set
(probably corrupted streams only).
