* mem: fix pointer pointer aliasing violationsRémi Denis-Courmont2015-02-01
| | | | | | | | | This uses explicit memory copying to read and write pointer to pointers of arbitrary object types. This works provided that the architecture uses the same representation for all pointer types (the previous code made that assumption already anyway). Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* ogg: Provide an option to offset the serial numberLuca Barbato2015-02-01
| | | | | The ogg serial number doubles as codec id and sequence value for concatenated samples.

* mpegvideo_enc: initialize the encoding contextVittorio Giovara2015-01-29
| | | | | | | | This prevents several uninitialized variable uses that take place towards the end of encoding. CC: libav-stable@libav.org Bug-Id: CID 700760

* avio: Do not consider the end-of-buffer position validLuca Barbato2015-01-28
| | | | | | | | | | | | | | 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. CC: libav-stable@libav.org

* lavc: support extracting audio service type from side dataAnton Khirnov2015-01-27
|
* mov: export audio service type as side dataAnton Khirnov2015-01-27
|
* lavf: add a convenience function for adding side data to a streamAnton Khirnov2015-01-27
|
* Add a side data type for audio service type.Anton Khirnov2015-01-27
| | | | | Currently, audio service type is a field in AVCodecContext. However, side data is more appropriate for this kind of information.
* nutenc: do not use has_b_framesAnton Khirnov2015-01-27
| | | | | It is unreliable, especially when the stream codec context is not the encoding context. Use the codec descriptor properties instead.
* lavc: deprecate unused AVCodecContext.stream_codec_tagAnton Khirnov2015-01-27
|
* avidec: do not export stream_codec_tagAnton Khirnov2015-01-27
| | | | Handle its only existing use case internally.
* h264: drop any pretense of support for data partitioningAnton Khirnov2015-01-27
| | | | | | | | | | 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.
* h264_parser: restore a comment lost in 0268a54Anton Khirnov2015-01-27
|
* h264: do not reset the ref lists in flush_change()Anton Khirnov2015-01-27
| | | | | They are always constructed anew when needed, so there is no need to reset them explicitly.
* h264: move parser-only variables to their own contextAnton Khirnov2015-01-27
|
* error_resilience: move the MECmpContext initialization into ER codeAnton Khirnov2015-01-27
| | | | | | | 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.

* h264: simplify code in flush_dpb()Anton Khirnov2015-01-27
| | | | | There is no point in clearing reference explicitly, since that will be done as a part of ff_h264_unref_picture() right below.

* mov: Do not compute negative SAR valuesVittorio Giovara2015-01-23
| | | | | | | | This partially reverts cf70ba37ba74089a18295b29e77dead0a3222c9e, since it didn't take into account when rotation is 0, but there is another valid operation (eg. translation) in the matrix. Found-by: Michael Niedermayer <michaelni@gmx.at>
* mpegvideo_enc: Draw edges on input for non-multiple of 16 resolutionsMichael Niedermayer2015-01-23
| | | | | | | | | | | | 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).
