| * h264: initialize H264Context.avctx in init_thread_copyAnton Khirnov2015-02-21
| | | | | | | | | | This prevents using a wrong (first thread's) AVCodecContext if decoding a frame in the first pass over all threads fails.

| * 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.

| | | | | | | | | | They are always constructed anew when needed, so there is no need to reset them explicitly.

| * 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.

| * lavc: deprecate the use of AVCodecContext.time_base for decodingAnton Khirnov2014-10-15
| | | | | | | | | | | | | | | | | | | | | | When decoding, this field holds the inverse of the framerate that can be written in the headers for some codecs. Using a field called 'time_base' for this is very misleading, as there are no timestamps associated with it. Furthermore, this field is used for a very different purpose during encoding. Add a new field, called 'framerate', to replace the use of time_base for decoding.
