* avcodec: add constants for KLV pseudo-profile.Brad Hards2020-05-31
| | | | | | | | | | | | | | | | | There are two different ways KLV is used in MISB specs - sync and async. The corresponding text (in ST1401) says: ISO/IEC 13818-1 Table-34 defines a stream_type = 0x15 for “Metadata carried in PES packets,” and Table 2-22 defines a stream_id = 0xFC for “metadata stream.” and In ISO/IEC 13818-1, Table-34 defines a stream_type = 0x06 for “PES packets containing private data,” and Table 2-22 defines a stream_id = 0xBD for “private_stream_1.” These constants allow us to distinguish the two cases, as codec profiles.
