Comment (by bjoernv@…):

 Instead of writing a new HEVCParser (a HEVC/H.265 variant of the existing
 mythtv/libs/libmythtv/mpeg/H264Parser.cpp parser) from scratch, it may be
 a good idea to base on the existing FFmpeg parsers.

 Newer versions of FFmpeg including FFmpeg 3.2 included in MythTV 29, have
 a parser called h2645_parse
 (mythtv-29/mythtv/external/FFmpeg/libavcodec/h2645_parse.c). The HEVC code
 (mythtv-29/mythtv/external/FFmpeg/libavcodec/hevc_parse.c) is small,
 because most functions are inherited from h2645_parse.

 I can not estimate, how much work this will be.

 Since none of the VDR systems for Linux currently have full support for
 the German DVB-T2 HD (HEVC codec) TV standard, some people work on hacks,
 which work more or less. Here people from Linux DVR have made patches for
 HEVC:
