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>	10 years ago
Vittorio Giovara	40cf1bbacc	Deprecate avctx.coded_frame The rationale is that coded_frame was only used to communicate key_frame, pict_type and quality to the caller, as well as a few other random fields, in a non predictable, let alone consistent way. There was agreement that there was no use case for coded_frame, as it is a full-sized AVFrame container used for just 2-3 int-sized properties, which shouldn't even belong into the AVCodecContext in the first place. The appropriate AVPacket flag can be used instead of key_frame, while quality is exported with the new AVPacketSideData quality factor. There is no replacement for the other fields as they were unreliable, mishandled or just not used at all. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	10 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>	10 years ago

Reimar Döffinger	6724254118	ffv1enc: reduce stack usage. A bit more complex than e.g. adding it to the context, but using the context for something that will be used only during initialization seemed a bit wasteful. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	11 years ago

Michael Niedermayer	abe76b851c	ffv1enc: Make ffv1.3 non experimental The fate tests change as they used 1.2 previously The increased size is due to: 32bit CRCs per slice by default (can be disabled), it adds slice headers to allow decoding one slice without the others an additional slice size field is added to make it possible to find slices within corrupted surroundings. these add up to about 57bit per slice more at 50 frames and 4 slices thats 1425 byte Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
