Tim-Philipp Müller debe9caa36 typefindfunctions: only typefind text with a BOM as text/utf16 or text/utf32
We added the utf typefinder because the mp3 typefinder was a tad
overzealous when it came to typefinding things as mp3, and replaced
it with even more overzealous utf16/32 typefinders.

Fixes unit test.

Vincent Penquerc'h e67aa28de9 typefind: typefind UTF-16 and UTF-32
This avoids the MP3 typefinder from getting the highest score
every time it thinks there's something it might possibly be
able to parse.

Philip Jägenstedt 88491ff2e7 typefind: extract SOF marker in jpeg typefinder
The SOF types are defined by http://www.w3.org/Graphics/JPEG/itu-t81.pdf

This is needed to make sure that we plug a jpeg decoder that
can handle the type of JPEG we have (e.g. lossless JPEG)

Vincent Penquerc'h 4095551b31 typefind: recognize Asylum modules
Note that there is already a AMF detection for a different
magic, I'm not sure if that's a different format with the
same initials or not. AMF is used for a few different formats
(including video), so...

This fixes playbin2 playing Asylum modules.

Vincent Penquerc'h fa3e246866 typefind: bump probability if all frames we found are similar
Similar meaning same layer, same bitrate, and same number of channels

This fixes misdetection of (some MP3 files that have zero padding
between the ID3 tag and the MP3 stream) as H.264 video.

Tim-Philipp Müller 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.

René Stadler 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.

Arun Raghavan c77f88cac6 pbutils: add codec-specific utility functions for AAC
This allows us to add generic codec-specific functionality, like

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.

Tim-Philipp Müller 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.

.weba (audio) and .webv (video) were speculation on my part before

file extension for audio-only WebM, and I'm pretty sure there will
never be one for video-only.
