* cbs_h265: Detect more reference combinations which would overflow the DPBMark Thompson2021-03-12
| | | | | | | | | | | | | | | | | | | | | In total, the number of short term references (from the selected short term ref pic set), the number of long term references (combining both the used candidates from the SPS and those defined in the slice header) and the number of instances of the current picture (usually one, but can be two if current picture reference is enabled) must never exceed the size of the DPB. This is a generalisation of the condition associated with num_long_term_pics in 7.4.7.1. We use this to apply tighter bounds to the number of long term pictures referred to in the slice header, and also to detect the invalid case where the second reference to the current picture would not fit in the DPB (this case can't be detected earlier because an STRPS with 15 pictures can still be valid in the same stream when used with a different PPS which does not require two DPB slots for the current picture).

* cbs_h265: Ensure that a predicted RPS doesn't contain too many picturesMark Thompson2020-05-20
| | | | | | | | | If the RPS we are predicting from has maximum size then at least one of the pictures in it must be discarded before adding the current one. Also revert 588114cea4ee434c9c61353ed91ffc817d2965f5, which added now-redundant checks for the special case of a too-large RPS with all pictures being in the same direction from the current one.

| | | | | | | | | | | This commit fixes the names and constants of the reserved NAL units with nal_unit_type 22 resp. 23. They were "IRAP_IRAP_VLC2x", but are actually "RSV_IRAP_VLC2x".

* lavc/cbs_h2645_syntax_template: Fix memleakAndriy Gelman2019-12-16
| | | | | | | | | | | | | | | | | payload_count is used to track the number of SEI payloads. It is also used to free the SEIs in cbs_h264_free_sei()/cbs_h265_free_sei(). Currently, payload_count is set after for loop is completed. Hence if there is an error and the function exits, the payload remains zero causing a memleak. This commit keeps track of payload_count inside the for loop to fix the issue. Note that that the contents of current are initialized with av_mallocz() so there is no need to zero initialize payload_count.
