 2015-02-13 08:35:15 +01:00
Anton Khirnov 1509c018bd mpegts: relax restrictions on matching the packet start in read_header 
analyze() is currently called both when probing and from read_header().
It determines the packet start by looking for the sync byte, followed by
unset Transport Error Indicator and valid adaptation_field_control.

This makes sense to do when probing, but once we already know the format
is MPEG-TS, it is counterproductive to be so strict -- e.g. in some
files the TEI might be set and analyze() might get called with a smaller
buffer than the one used for probing, resulting in a failure.

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.
 2015-01-27 09:17:48 +01:00
Anton Khirnov 80a11de7dc nutenc: do not use has_b_frames 
It is unreliable, especially when the stream codec context is not the

 2015-01-27 09:13:45 +01:00
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.
