f3e65f1c93 typefind: NULL check in degas_type_find
The length check isn't sufficient, an source might
report the correct length, but then still fail to
read the requested number of bytes for some reason.

030f639a8e android: make it ready for androgenizer
Remove the android/ top dir
Fixe the Makefile.am to be androgenized

To build gstreamer for android we are now using androgenizer which generates the
needed Android.mk files.

143dc4810d typefindfunctions: rename type playlist/m3u8 to application/x-hls
We should keep playlist/m3u8 available for normal m3u8 playlists,
which we we'll likely support some day. Also, we probably don't
want this handled like other playlists, so application/* seems
more appropriate in this case, even if it's really just a playlist.

886ea051e7 typefind: fix E-AC-3 frame size parsing
Frame size is given in words; it is already multiplied by two where
needed, so the left shift is superfluous. This extra multiplication
caused the code to inspect the third packet instead of the second,
which would fail for files where the second packet has a size
different from the first.

c77f88cac6 pbutils: add codec-specific utility functions for AAC
This allows us to add generic codec-specific functionality, like
extracting profile/level data from headers, without having to duplicate
code across demuxers and typefindfunctions.

As a starting point, this moves over AAC level extraction code from
typefindfunctions, so it can be reused in qtdemux, etc.

bd0adb11fd typefinding: make mpeg-ts typefinder scan more data
We only look for packets with payload, but it appears there may be packets without,
which makes it harder to find the N packets with payload in a row that we need in
order to typefind this successfully, so scan some more data than necessary in the
optimistic scenario. Alternatively we could change IS_MPEGTS_HEADER().

Fixes #623663.

72ca12e4c1 typefind: only associate .webm with WebM
.weba (audio) and .webv (video) were speculation on my part before
the public launch. As of yet no decision has been made on the
file extension for audio-only WebM, and I'm pretty sure there will
never be one for video-only.

b5a7e96291 typefinding: look for dts frames at non-zero offsets too

Make jpeg typefinder check more than just the first two bytes

making typefinding stop early. Also extract width and height,
because we can.

14d14a9143 typefinding: fix AC-3 typefinding so that it actually checks for a second frame
Fix typo that made the AC-3 typefinder not actually check for a
second frame, but rather compare the sync point found to itself,
which resulted in the AC-3 typefinder reporting an overly optimistic
MAXIMUM or VERY_LIKELY probability when it found a possible frame
sync.

43a04483d9 typefinding: add AAC level to ADTS caps
This adds code to calculate the level for a given AAC stream and export
it in the stream caps. For AAC LC streams, the level is calculated
according to the definition under the AAC Profile. For other streams,
the definition under the Main Profile is used.

HE-AAC support is still to be done, and is dependent on detecting the
presence of SBR and PS in the stream.

Level is added as a field of type string because that's the way it's
done in H.264 caps as well. There are only a few possible levels, so
not using a numerical type is not too painful in this case, and
consistency is nice.

Fixes #613589.
