AVCodecContext.encode is currently used only for subtitles, encode2 is
used for audio and video.

Silences a warning about discarding const.

The buffer sink does not take any parameters.

Fixes an uninitialized variable warning.

It would have been done anyway in the av_dict_set() call.

This simplifies the code and avoid a warning because of assigning a
const string from ff_id3v1_genre_str to a non-const variable.

These functions do not benefit from being inlined.  They are large,
and there are no opportunities for constant propagation.

It internally decodes as float and then converts to s16 by a call to
float_to_int16(). The caller can do this just as well by using lavr.

Gray8 is not considered to be paletted, so this would cause an invalid
write.

Fixes bug 367.

Also clarify the meaning of the log message.

This is consistent with stdio and is what we want to do in all cases.

Fixes a bug in the voc muxer which didn't flush in write_trailer()
previously. This is the cause of the change in the test results.

This is consistent with stdio, and thus what people would naturally
expect.

Some compilers are extra strict about register usage in main(),
disallowing ebp in inline asm there while allowing it elsewhere.
This change makes the test better reflect actual usage.

In both usages of FASTDIV the denominator might be 1.

Using a branch could make the function slower than using a normal
division.

Both denominator and numerator can be multiplied by 2 safely and
using shifts is faster than using a branch.

Do not crash if the input format is not allocated yet.

avio_close checks by itself for NULL condition.

The missing headers are required for errno and for strerror.
