From bbc0eb7fcb6dbf305b78e83b08c5930ce8b29ff6 Mon Sep 17 00:00:00 2001 From: Brad Hards Date: Wed, 27 May 2020 20:01:59 +1000 Subject: [PATCH] avcodec: add constants for KLV pseudo-profile. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.
