avconv: Report the codec and the encoder separately
Merged-by: Michael Niedermayer <michaelni@gmx.at>
Avoid buffer overruns when processing some MOV files with the amerge
filter. Files produced by Adobe Premiere Pro CC have up to one second of audio
not interleaved. With common settings (<= 48kHz) that makes up to 47 frames so
a queue length of 64 makes sense.
Fixes ticket #3510.

When the joint table does not contain a valid entry, the decoding restarts
from scratch. By implementing the trick of jumping to the 2nd level of the
individual table (and inlining the whole), a speed improvement of 5-10%
is possible.

build: check if AS supports the '.func' directive
Merged-by: Michael Niedermayer <michaelni@gmx.at>
This allows the caller to write all buffered data to disk, allowing
the caller to know at what byte position in the file a certain
packet starts (any packet written after the flush will be located
after that byte position).

It was instead using the highest available asm functions, which completely
kills the point of being a reference C context.

We cannot use avpriv_request_sample() as this is private to the libs
or rather it would be a bad usage example

It seems working without this now for the files i tested it with, if this causes
a regression, dont hesitate to put the line back or open a ticket or fix (if possible)
the parser

Move the GNU as check before the arch specific asm checks since the .dn
check requires gas compatible assembler.
Disable the VC-1 motion compensation NEON asm which is the only part
using that directive. The integrated assembler in the upcoming clang 3.5
does not support .dn/.qn without plans to change that. Too much effort
to implement it while it is rarely used.
http://llvm.org/bugs/show_bug.cgi?id=18199.
Both gnu as and clang treat lines starting with '#' as comments if they
aren't consumed by the C-style preprocessor.
Using '//' does not work with clang since comments are removed before
macro expansion.
