* | avcodec/hevc_sei: fix amount of bits skipped when reading picture timing SEI ↵James Almer2017-05-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | message The code was skipping the entire reported SEI message size regardless of the amount of bits read. While in theory safe for NALU where the picture timing SEI message is alone or at the end as we're using the checked bitstream reader, it isn't in any other situation, where every SEI message in the NALU after the picture timing one would potentially fail to parse. Change the function name to one more in line with the rest of file, and remove the bogus "Skipped SEI" debug message while at it.

| | | | | | | | | | | | | | This way they can be reused by other code without including the whole decoder-specific hevcdec.h Also, add the HEVC_ prefix to them, since similarly named values exist for H.264 as well and are sometimes used in the same code.

* | avcodec: Use get_ue_golomb_long() when neededMark Harris2015-12-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
