Subject: [PATCH] avcodec/hevcdec: fix non-ref frame judgement
After inspecting the source code of x265, mpv and ffmpeg, I've found that
ffmpeg mistakenly regards EVC_NAL_BLA_N_LP and HEVC_NAL_IDR_N_LP as non-
reference frames, which are acutally reference frames according to the
specification in x265, and drops them.
This patch should address the problem. I have tested it with mpv.
