Vittorio Giovara 302ca6b20e mpegvideo_enc: initialize the encoding context 
This prevents several uninitialized variable uses that take
place towards the end of encoding.

Luca Barbato 3c18a7b188 avio: Do not consider the end-of-buffer position valid 
Trigger a refill if the seek action moves the pointer
at the end of the buffer.

Before this patch the read action following the seek would trigger
the refill, while write action would write outside the buffer.

In the Libav codebase few muxers seek forward outside of what
already has been written so it is quite unlikely to experience
the problem with the default buffer size.

Anton Khirnov 4227e4fe74 lavf: add a convenience function for adding side data to a stream 2015-01-27 09:18:32 +01:00
Anton Khirnov 728685f37a Add a side data type for audio service type. 
Currently, audio service type is a field in AVCodecContext. However,
side data is more appropriate for this kind of information.

Anton Khirnov 80a11de7dc nutenc: do not use has_b_frames

Anton Khirnov 167e004e1a h264: drop any pretense of support for data partitioning 
It does not work correctly and apparently never did. There is no
indication that this (mis)feature is ever used in the wild or even that
any software other than the reference supports it.

Since the code that attempts to support it adds some nontrivial
complexity and has resulted in several bugs in the past, it is better to
just drop it.

Anton Khirnov 9404a47a2d h264: move parser-only variables to their own context 2015-01-27 09:08:31 +01:00
Anton Khirnov cf1e0786ed error_resilience: move the MECmpContext initialization into ER code 
Currently, it needs to be initialized by the ER caller (which is
currently either a mpegvideo decoder or h264dec). However, since none of
those decoders use MECmpContext for anything except ER, it makes more
sense to handle it purely inside ER.

This partially reverts cf70ba37ba, since
it didn't take into account when rotation is 0, but there is another
valid operation (eg. translation) in the matrix.

Michael Niedermayer 2a06c2a03e mpegvideo_enc: Draw edges on input for non-multiple of 16 resolutions 
This improves motion estimation and avoids using uninitialized data
for resolutions that aren't a multiple of 16.

Prior to d2a25c40, the edges used to be initialized so that encoding
was deterministic, but after that commit it started using uninitialized
data (for non multiple of 16 resolutions).
