* hevc_refs: reduce code duplication in find_ref_idx()Anton Khirnov2020-06-08

* lavc/hevc_refs: Fix the logic of find_ref_idx()Xu Guangxin2020-05-27
| | | | | | | | | | | | | | | | | | | | | | | | | Currently find_ref_idx() would trigger 2 scans in DPB to find the requested POC: 1. Firstly, ignore MSB of ref->poc and search for the requested POC; 2. Secondly, compare the entire ref->poc with requested POC; For long term reference, we are able to only check LSB if MSB is not presented(e.g. delta_poc_msb_present_flag == 0). However, for short term reference, we should never ignore poc's MSB and it should be kind of bit-exact. (Details in 8.3.2) Otherwise this leads to decoding failures like: [hevc @ 0x5638f4328600] Error constructing the frame RPS. [hevc @ 0x5638f4328600] Error parsing NAL unit #2. [hevc @ 0x5638f4338a80] Could not find ref with POC 21 Error while decoding stream #0:0: Invalid data found when processing input Search the requested POC based on whether MSB is used, and avoid the 2-times scan for DPB buffer. This benefits both native HEVC decoder and integrated HW decoders. Signed-off-by: Xu Guangxin <guangxin.xu@intel.com> Signed-off-by: Linjie Fu <linjie.fu@intel.com>

| | | | | | | | | | | | | | 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.
