Some encoders (e.g. flac) need to send side data when there is no more
data to be output. This enables them to output a packet with no data in
it, only side data.

Only copy it manually in the muxers where it makes sense (rtspenc,
sapenc). Don't touch the original AVStream in movenchint, where
the original AVStream should be kept untouched.

This fixes the normal tracks in RTP hinted files after
abb810db - the hint tracks were ok while the normal media tracks
were broken, noticed by Michael Niedermayer.

This reverts abb810db but achieves the same effect for the other
muxers.

While it strictly isn't necessary to copy the time base (since
any use of it is scaled in ff_write_chained), it still is better
to signal the actual time base to the caller, avoiding one
unnecessary rescaling. This also lets the caller know what the
actual internal time base is, in case that is useful info
for some caller.

This reverts commit 397ffde1.

This allows making it visible without name clashes.

This fixes building in PIC mode with gas. The examples in the gas
manual showed using a # here even though gas itself actually didn't
support that syntax (and the gas test suite only tests it without
the extra hash sign).

Fixes calculating the ts offset for audio codecs with delay.

Do not fall back on the codec timebase, since that can be anything for
VFR video.

This results in DefaultDuration not being written when the framerate is
not known, but as this field is purely informative, this should not
break any sane demuxers.

First free metadata, then the side data it is contained in.

Utility function to get the upper bound on the number of samples the
resampler would output.

Add the low overhead pipe mode and the extended broadcast mode.
Export the options as 'syncponts' since it impacts only that.

This corrects the bug that caused the checksums to change in
9767d7c0.

It caused the EOS flag to be set incorrectly; the ogg spec does not
allow it to be set in the middle of a logical bitstream.

This allows reusing it from multiple files.

It is commonly stored in a vorbiscomment block in codec private data.

It contains all information that is used by the decoder and the other
FLAC-capable demuxers (flacdec, ogg) export only STREAMINFO as well.

This avoids all the ABI troubles associated with avpriv_.
Since this function is very small and does not depend on any tables,
making it inline should have no adverse effects.

It is used to store the channel mask for non-standard layouts.

The channel layout mask for non-standard layouts is typically stored at
the container level (as a vorbiscomment tag) for FLAC.

Before, header information for ogg format files was sent with the
first encoded packet.

This patch makes it so that it is possible for API users to
differentiate between headers and encoded audio. This is useful, for
example, when creating an audio stream where you want to send one set
of headers for every client that connects and then the encoded stream
of audio.
