Andreas Rheinhardt	a247ac640d	avcodec: Constify AVCodecs Given that the AVCodec.next pointer has now been removed, most of the AVCodecs are not modified at all any more and can therefore be made const (as this patch does); the only exceptions are the very few codecs for external libraries that have a init_static_data callback.

Andreas Rheinhardt	d85c41b572	avcodec: Remove private options from AVCodecContext Several options that were too codec-specific were deprecated between `0e6c853221` and `0e9c4fe254`.

Andreas Rheinhardt	ce482266a6	avcodec/alacenc: Don't free unnecessarily The init function of the ALAC encoder calls its own close function if a call to ff_lpc_init() fails; yet nothing has been allocated before that point (except extradata which is freed generically) and ff_lpc_init() can be expected to clean up after itself on error (the documentation does not say anything to the contrary and the current implementation can only fail if the only allocation fails, so there is nothing to clean up on error anyway), so this is unnecessary.

Vittorio Giovara	243df1351d	lavc: Move {min,max}_prediction_order to codec private options These options are only used by alac and flac. They are very codec-specific options, so deprecate the global variants. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	9 years ago

Michael Niedermayer	e36db49b7b	avcodec: Add a min size parameter to ff_alloc_packet2() This parameter can be used to inform the allocation code about how much downsizing might occur, and can be used to optimize how to allocate the packet Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
Vittorio Giovara	d6604b29ef	Gather all coded_frame allocations and free functions to a single place Allocating coded_frame is what most encoders do anyway, so it makes sense to always allocate and free it in a single place. Moreover a lot of encoders freed the frame with av_freep() instead of the correct API av_frame_free(). This bring uniformity to encoder behaviour and prevents applications from erroneusly accessing this field when not allocated. Additionally this helps isolating encoders that export information with coded_frame, and heavily simplifies its deprecation. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	9 years ago
