* h264: decouple h264_sei from the h264 decoderAnton Khirnov2016-04-24
| | | | | Make the SEI parsing independent of the H264Context, to allow decoupling the parser from the decoder.
* h264: decouple h264_ps from the h264 decoderAnton Khirnov2016-04-24
| | | | | | | | | 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.
* h264: Print the complete user messageVittorio Giovara2015-10-30
| | | | | | | Previously the message was cut off at 256th byte. This will allow dumping the complete x264 encode info when needed. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>
* h264: Print user data SEI under normal debug verbosityVittorio Giovara2015-10-30
| | | | | | Drop the need of setting -debug bugs since it's not a bug, and the message is already under a AV_LOG_DEBUG log level. Instead only print it when there is an actual string in it.

* avcodec: h264: Extract decoder methodsDavid Holm2015-08-01
| | | | | | | | | | | Extract two methods from decode_registered_user_data in order to improve code readability. Also make the constant holding the allocation size a 64-bit unsigned integer so that the size comparison against INT_MAX makes sense.

* h264: deMpegEncContextizeAnton Khirnov2013-02-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | Most of the changes are just trivial are just trivial replacements of fields from MpegEncContext with equivalent fields in H264Context. Everything in h264* other than h264.c are those trivial changes. The nontrivial parts are: 1) extracting a simplified version of the frame management code from mpegvideo.c. We don't need last/next_picture anymore, since h264 uses its own more complex system already and those were set only to appease the mpegvideo parts. 2) some tables that need to be allocated/freed in appropriate places. 3) hwaccels -- mostly trivial replacements. for dxva, the draw_horiz_band() call is moved from ff_dxva2_common_end_frame() to per-codec end_frame() callbacks, because it's now different for h264 and MpegEncContext-based decoders. 4) svq3 -- it does not use h264 complex reference system, so I just added some very simplistic frame management instead and dropped the use of ff_h264_frame_start(). Because of this I also had to move some initialization code to svq3.
