James Almer	9669c05baf	avcodec/h264_sei: add namespace prefix to frame packingarrangement enum values Missed in `6eb102a616`. Signed-off-by: James Almer <jamrial@gmail.com>	7 years ago
Mark Thompson	6eb102a616	h264_sei: Add namespace prefix to all SEI values This avoids confusion with equivalent H.265 SEI values when both are being used at the same time. (cherry picked from commit `6ea220cbee`)	7 years ago
Vittorio Giovara	8c34a2024d	h264: Add support for alternative transfer characterics SEI The use of this SEI is for backward compatibility in HLG HDR systems: older devices that cannot interpret the "arib-std-b67" transfer will get the compatible transfer (usually bt709 or bt2020) from the VUI, while newer devices that can interpret HDR will read the SEI and use its value instead.

Anton Khirnov	1cf2f3d334	h264_sei: drop an unnecessary h264dec.h include The code does not depend on the h264 decoder anymore and only needs information from h264_ps	9 years ago
Anton Khirnov	9df889a5f1	h264: rename h264.[ch] to h264dec.[ch] This is more consistent with the naming of other decoders.	9 years ago
Clément Bœsch	7dd8cd1933	lavc/h264_sei: fix broken style around green metadata code	9 years ago
Clément Bœsch	5342bb624d	lavc/h264: rename GreenMetaData to H264SEIGreenMetaData Reduces diff for the next merge with Libav.	9 years ago
Clément Bœsch	b0ec36c9b1	lavc/h264_sei: reduce scope of parameters for green meta decode This is again will help the merge as ff_h264_decode_sei will not have access to H264Context anymore.	9 years ago
Clément Bœsch	fef89aae98	lavc/h264: move green meta logging out of the sei decoding This will simplify the next Libav merge where SEI decoding doesn't have access to the debug level anymore.	9 years ago

Anton Khirnov	728d90a0c1	h264: decouple h264_sei from the h264 decoder Make the SEI parsing independent of the H264Context, to allow decoupling the parser from the decoder.	9 years ago
Anton Khirnov	3176217c60	h264: decouple h264_ps from the h264 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.	9 years ago
Mark Harris	c51c08e0e7	avcodec: Use get_ue_golomb_long() when needed get_ue_golomb() cannot decode values larger than 8190 (the maximum value that can be golomb encoded in 25 bits) and produces the error "Invalid UE golomb code" if a larger value is encountered. Use get_ue_golomb_long() instead (which supports 63 bits, up to 4294967294) when valid h264/hevc values can exceed 8190. This updates decoding of the following values: (maximum) first_mb_in_slice 36863* for level 5.2 abs_diff_pic_num_minus1 131071 difference_of_pic_nums_minus1 131071 idr_pic_id 65535 recovery_frame_cnt 65535 frame_packing_arrangement_id 4294967294 frame_packing_arrangement_repetition_period 16384 display_orientation_repetition_period 16384 An alternative would be to modify get_ue_golomb() to handle encoded values of up to 49 bits as was done for get_se_golomb() in `a92816c`. In that case get_ue_golomb() could continue to be used for all of these except frame_packing_arrangement_id. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
Vittorio Giovara	b4a82e7407	h264: Print the complete user message 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>	9 years ago
Vittorio Giovara	8487987b87	h264: Print user data SEI under normal debug verbosity 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.	9 years ago
