3d500636a9 adaptivedemux2: Don't use g_str_equal on potentially NULL strings
It is only meant to be used as a callback. The fallback macro uses strcmp which
doesn't handle NULL strings gracefully. Instead use g_strcmp0

711198a1a9 hlsdemux2: Ensure processed webvtt ends with empty new line
Parsers downstream will use empty new lines to detect where an entry
ends. Failure to have a newline would cause the entry to be either
discarded or (wrongly) concatenated with the next entry

42b0dd8c41 hlsdemux2: Split the stream object out
Move the stream object to a separate file to split the demux level behaviour
from the stream behaviour better.

3537614c2b hlsdemux2: Add and use gst_hls_media_playlist_find_position()
Add a function for synchronising current position with the contents of a
playlist that is specifically for that and can handle synchronising to a partial
segment.

gst_hls_media_playlist_seek() will be used only when performing external seek
requests, to find the best segment or partial segment at which to resume
playback.

74f25cca31 hlsdemux2: Look for mpegts synchronization point further
Some mpeg-ts streams have extra data at the beginning. While it's not ideal, we
should be able to cope with it.

Therefore increase the initial search window for at least 4 consecutive
synchronization points to 1kB.

8f2d347559 hls: Relax webvtt checks
If no hour field is present (which is allowed), the remaining data can be less
than 15 character.

Fix time translation failures if the hour field wasn't present

af78c16dd5 New HLS, DASH and MSS adaptive demuxer elements
This provides new HLS, DASH and MSS adaptive demuxer elements as a single plugin.

These elements offer many improvements over the legacy elements. They will only
work within a streams-aware context (`urisourcebin`, `uridecodebin3`,
`decodebin3`, `playbin3`, ...).

Stream selection and buffering is handled internally, this allows them to
directly manage the elementary streams and stream selection.
