James Almer	2cb656ad11	avcodec/mjpegenc: move ff_mjpeg_encode_picture_frame to mjpegenc_common Fixes compilation of ljpeg encoder if mjpeg and amv encoders are disabled	8 years ago
Vittorio Giovara	2862b63783	lavc: Move prediction_method to codec private options This options is only used by huffyuv, ffvhuv, jpegls, mjpeg, mpegvideoenc, png, utvideo. It is a very codec-specific options, so deprecate the global variant. Set proper limits to the maximum allowed values, and update utvideoenc tests to use the new option name.

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	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>	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

Anton Khirnov	24abd806ea	ljpegenc: deMpegEncContextize The encoder uses almost none of the mpegvideo infrastructure, only some fields from MpegEncContext. The FATE results change because now an all-zero quant matrix is written into the file. Since it is not used for anything for ljpeg, this should not be a problem.	11 years ago
