It sets the supplied AVFormatContext pointer to NULL after freeing it,
which is safer and its name is consistent with other lavf functions.

Also deprecate av_close_input_file().

And remove all its uses.

The change in 599b4c6e didn't turn out to work properly on
i386 on OS X, where it broke building with PIC enabled.

Firstly, this test never worked as intended, always reporting
success.  Secondly, bswap is available from 486 onward and can
thus be assumed present.

With these changes, gcc 4.5 and later recognise it as a bswap
and use the proper instructions on ARM and x86.  On x86, the
16-bit bswap is recognised from gcc 4.1.

Make the function prototype match the argument of
AVCodecCntext.execute() and remove the cast hiding
this mismatch.

This replaces the explicit offset(reg) memory references with
"m" operands for the same locations.  As a result, one fewer
register operand is needed for these inline asm statements.

Multi-channel output works just fine for me with SDL 1.2.14.

When the buf and last pointers are equal, the FFSWAP() results
in an invalid call to memcpy() with same source and destination
on some targets.  Although assigning a struct to itself is valid
C99, gcc does not check for this before calling memcpy().

The existing functions defined in intfloat_readwrite.[ch] are
both slow and incorrect (infinities are not handled).

This introduces a new header with fast, inline conversion
functions using direct union punning assuming an IEEE-754
system, an assumption already made throughout the code.

The one use of Intel/Motorola extended 80-bit format is
replaced by simpler code sufficient under the present
constraints (positive normal values).

The old functions are marked deprecated and retained for
compatibility.

If the sdp is generated before the rtp muxer is initialized
(e.g. as when called from the rtsp muxer), this has to be done,
otherwise the rtp muxer doesn't know that the input really is
in mp4 format.

If an annex b bitstream is muxed into mov, the actual written
sample is reformatted to mp4 syntax before writing.

Currently, the RTP hints that copy data from the normal video
track, where the payload data might be offset compared to the
original sample that the RTP hinting used (when 3 byte
annex b startcodes have been converted into 4 byte mp4 format
startcodes).

Also remove mentions of it from other avtools' manuals.

It's broken and doesn't work anyway.

This patch means that avconv will ignore encoding options from the ffm
file and will instead use whatever is provided on the commandline as for
normal output.

It's not supposed to be set outside of lavc. Set r_frame_rate and
avg_frame_rate instead.
