The beginning of the private contexts of both the FLAC and the TAK demuxer currently mimick FFRawDemuxerContext: A pointer to an AVClass followed by the AVOpt-enabled field raw_packet_size. Said field is only used by the demuxers' read_packet functions via ff_raw_read_partial_packet(), which treats the private context as an FFRaawDemuxerContext. Yet this is fragile, so better include a FFRawDemuxerContext struct at the beginning of said demuxers' private contexts. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
