Luca Barbato	fe6e5cbea7	ffv1: Remove version 2 and mark version 3 as non-experimental The encoder produces bitstream compatible with the current specification and version 2 is set as reserved (non-standardizable).	9 years ago
Alexandra Hájková	5c31eaa999	Remove unnecessary get_bits.h #includes and add missing headers where needed. Signed-off-by: Diego Biurrun <diego@biurrun.de>	9 years ago
Vittorio Giovara	96c373c770	lavc: Move context_model to codec private options This option is only used by ffv1 and ffvhuff. It is a very codec-specific option, so deprecate the global variant. Improve documentation a little. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	9 years ago
Clément Bœsch	e8bc642202	lavu: add AV_CEIL_RSHIFT and use it in various places Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	9 years ago
Vittorio Giovara	be00ec832c	lavc: Deprecate coder_type and its symbols Most option values are simply unused or ignored and in practice the majory of codecs only need to check whether to enable rle or not. Add appropriate codec private options which better expose the allowed features. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	9 years ago
Vittorio Giovara	4bb1070c15	ffv1: Explicitly name the coder type FFv1 uses two types of coders, golomb and range with two different tables. This is exposed this in a rather convoluted way, for example mentioning to set coder type 1 while initializing the variable 'ac' to 2, because encoder does not use range coder with default table. Appropriate internal coder type values have been added and used in any check rather than using raw numbers. Initialization of avctx.coder_type in ffv1dec is removed because this field is encoder only. An unneeded validation check in the encoder is dropped too.

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
