Anton Khirnov	7ea1b3472a	lavc: deprecate the use of AVCodecContext.time_base for decoding 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.	10 years ago

Anton Khirnov	7d84826400	cavs: deMpegEncContextize It does not use any of the mpegvideo infrastructure, just a few fields from the context. Fixes a segfault with the emu edge flag, since emu edge buffer is now allocated as a part of the frame buffer allocation and cavs calls ff_get_buffer() directly, it does not use mpegvideo buffer management. Fixes a memleak of the last frame.	12 years ago

Martin Storsjö	eaa9b2e66c	avcodec: Rename avpriv_frame_rate_tab to ff_mpeg12_frame_rate_tab This table doesn't need to be shared with libavformat any longer. Add mpeg12 to the name to make it less ambiguous, while renaming it. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Diego Biurrun	f75f4194d1	Restructure av_log_missing_feature message Some invocations include a verb in the log message, others do not. Yet av_log_missing_feature expects callers to provide a verb. Change the function to include a verb instead and update the callers accordingly. The result is a more natural function API and correct English in the function invocations.	12 years ago
