TTA does not support float at all, and format 2 is encrypted TTA.

It's only used in avconv, so it properly belongs to OutputStream struct
there.

Prevents -c copy from working for input streams and allows to move
stream_copy variable from AVStream to OutputStream.

Deprecate AVFormatContext.preload.

audio_resample can not reduce the number of channels

This avoids warnings from the overflow checker and simplifies the code.

During slice threading only MpegEncContext is passed to
mpeg_decode_slice, remove a wrong cast and change the function
definition to take MpegEncContext pointer.

This reverts commit da22ba7d since it
broke slice threading. Slice threading just duplicates MpegEncContext
so every value used during mpeg_decode_slice has to be in it.
A second patch will fix the illusion that Mpeg1Context is available
in mpeg_decode_slice.

This fixes assembling using "nasm".

for example:
Attempting to set ac3 dsur_mode to "on" results in:
[AC-3 Encoder @ 0x7f508f0a3280] Value 2.000000 for parameter 'dsur_mode' out of range
[AC-3 Encoder @ 0x7f508f0a3280] Error setting option dsur_mode to value on.

It's not used anywhere else.

It's MPEG-1/2 specific.

It's MPEG-1 specific.

It will be used in vdpau code.

The code was mistakenly removed in cad16562.
It stored some motion vector data for future use in B-pictures.

This fixes Bugzilla bug #57.
