* avformat/mpegtsenc: set stream_id correctly based on KLV profile selectedBrad Hards2020-05-31

* 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.

* lavfi/vulkan: use av_get_random_seed instead of randLynne2020-05-29
| | | | | | | | We need at least a few bits of entropy to determine the start index of each queue, in order to let filters run in parallel as much as possible, and rand() is not thread safe and disrupts any external API's usage of rand, so instead replace it with av_get_random_seed. While it has more overhead than rand, we only run it once per filter upon init.

* avformat/hlsenc: Avoid duplicating strings when parsingAndreas Rheinhardt2020-05-28
| | | | | | | | | | | | | | | | | | | Up until now, the HLS muxer uses av_strtok() to split an input string controlling parameters of the VariantStreams and then duplicates parts of this string containing parameters such as the language or the name of the VariantStream. But these parts are proper zero-terminated strings of their own that are never modified lateron, so one can simply use the substring as-is without creating a copy. This commit implements this. The same also happened for the string controlling the closed caption groups. Furthermore, add const to indicate that the pointers to these substrings are not used to modify them and also to indicate that these strings are not allocated on their own.

* avformat/mpegts: use get_packet_size in mpegts_resync for determining ↵Marton Balint2020-05-27
| | | | | | | | | | | | | | | | | | | raw_packet_size The old resync logic had some bugs, for example the packet size could stuck into 192 bytes, because pos47_full was not updated for every packet, and for unseekable inputs the resync logic simply skipped some 0x47 sync bytes, therefore the calculated distance between sync bytes was a multiple of 188 bytes. AVIO only buffers a single packet (for UDP/mpegts, that usually means 1316 bytes), so for every ten consecutive 188-byte MPEGTS packets there was always a seek failure, and that caused the old code to not find the 188 byte pattern across 10 consecutive packets. This patch changes the custom logic to the one which is used when probing to determine the packet size. This was already proposed as a FIXME a long time ago...
