588b6215b4 rtmpcrypt: Do the xtea decryption in little endian mode
The XTEA algorithm operates on 32 bit numbers, not on byte sequences.
The XTEA implementation in libavutil is written assuming big endian
numbers, while the rtmpe signature encryption assumes little endian.

This fixes rtmpe communication with rtmpe servers that use signature
type 8 (XTEA), e.g. crunchyroll.

d07585f04a avformat/async: Fix bug where async could not recover after seek to eof
When async issues its inner seek via ffurl_seek, it treats failures as
EOF being reached. This is not consistent with the behavior of other
protocols (e.g. http, cache) which continue to tolerate reads after
failed seeks, and therefore does not interact correctly with them.

A common pattern where this manifests itself is where avio_seek is
called with pos to be the end-of-file - the http range-request would
fail here, and async would set io_eof_reached to 1. The background
thread would then refuse to read more bytes, and subsequent reads would
only empty the fifo and end in an error.

Presumably the code may have expected subsequent seeks to unset the
io_eof_reached but this is not guaranteed to be true - a subsequent seek
that lands in the AVIOContext's buffer (the fact that the
previously-failed avio_seek leaves the AVIOContext's buffer intact also
suggests that follow-up reads are expected to be tolerated) would not be
issued to the async_seek function, and when that buffer is drained only
async_read calls would follow, leading to the same error just described.

b1a32429ef hevc: Fix a53 caption extraction
Just realized my previous patch doesn't work quite right.  I uploaded a better
sample file that actually has visible captions to /incoming/hevc_cc.ts.  I
tested with that file doing hevc->x264 and it works.

This is basically an exact copy of the existing h264 logic.

b5f963bfec mov: Drop dref when unable to parse
Some entries might be either empty or contain types we do not parse
(eg. 'url '). In both cases, if an 'alis' is not the first entry,
external references are not loaded, so make sure that the array starts
with an 'alis' dref.

303f931938 mov: Correctly store dref paths
Rather than reading the alternate absolute path version from dref
type 18, make sure that 0s are considered as '/'. These values are
sometimes present in the full path, and are mistakenly interpreted as
line terminators othewise.

With the correct handling of this dref type, parsing type 18 is not
needed any more.

bef3b1f59f movenc: Allow setting start_dts/start_cts before writing actual packets
By writing a zero-sized packet, the caller can communicate the
start_dts/start_cts for the stream without actually writing
the first packet.

This allows doing random-access writing of fragments when the
start dts of the stream isn't zero, so that the edit list in the moov
is written based on timestamps from the nominal start time signaled
via the zero-sized packet, while the first proper packet written
corresponds to a later fragment.

To avoid potential unexpected behaviour, empty packets only set
start_dts if the frag_discont flag is set.
