| | | | | | | | | | | | | | | | | | This caused mpv (and possibly others) to fallback to software decoding after seeking a VC1 stream. Bug-Id: 667 Signed-off-by: Luca Barbato <lu_zero@gentoo.org>

| | | | | | | | | | | | | | | | | | | | | | | | This allows further unrolling the DSP implementation where possible. x86 and ARM DSP modified by simply moving the multiple calls from vc1dec to the DSP code. Decoding improvements should only occurs because of the compiler actually able to unroll more. Decoding time: ~8.80s -> 8.64s (ie around 2%) Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

| | | | | | | | | | | | | | | | | | | | | | | | | | 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. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>

| | | | | | | | | | | | | | 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.

| * mpegvideo: do not set current_picture_ptr in decodersAnton Khirnov2013-12-05
| | | | | | | | | | | | | | | | | | | | | | 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.
