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.

Previously the message was cut off at 256th byte.
This will allow dumping the complete x264 encode info when needed.

h264: Print user data SEI under normal debug verbosity
Merged-by: Hendrik Leppkes <h.leppkes@gmail.com>

| |
| |
| |
| | |
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.

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.
