Timothy Gu	bc22cd244e	dnxhdenc: Optimize get_pixels_8x4_sym for 10-bit This reverts commit `628e6d0164` and uses a better fix. Before: 4483 decicycles in get_pixels_8x4_sym, 131032 runs, 40 skips After: 2569 decicycles in get_pixels_8x4_sym, 131054 runs, 18 skips	9 years ago
Christophe Gisquet	96b165fae2	dnxhd: interleave AC levels and flags This allows more efficient access to the array as the level and flags are contiguous. Around 4% faster coefficient decoding. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
Christophe Gisquet	234369d0fd	dnxhdenc: fix access outside of image This is the same test as for the 8bit case.	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

Michael Niedermayer	caba19a5be	avcodec/dnxhdenc: Set pict type for AV_PKT_DATA_QUALITY_STATS correctly Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
Michael Niedermayer	c40ecffd31	Replace AV_PKT_DATA_QUALITY_FACTOR by AV_PKT_DATA_QUALITY_STATS The stats are a superset of the quality factor, also allowing the picture type and encoder "PSNR" stats to be exported This also replaces the native by fixed little endian order for the affected side data AV_PKT_DATA_QUALITY_FACTOR is left as a synonym of AV_PKT_DATA_QUALITY_STATS 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	5d3addb937	Add a quality factor packet side data This is necessary to preserve the quality information currently exported with coded_frame. Add the new side data to every encoder that needs it, and use it in avconv. 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
Vittorio Giovara	910247f172	lavc: Deprecate avctx.{inter,intra}_quant_bias They are used by dnxhd and mpegvideo_enc exclusively, move them to codec private options instead. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	10 years ago
