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

Luca Barbato	3c27275c13	tiff: Check the check_size() return value and forward it Also use the same type for add_entry and check_size. Bug-Id: CID 700699 CC: libav-stable@libav.org Signed-off-by: Luca Barbato <lu_zero@gentoo.org> Signed-off-by: Vittorio Giovara <vittorio.giovarao@gmail.com>	10 years ago
Vittorio Giovara	0562887a98	tiffenc: initialize return value 'ret' can only be used without initialization if s->height <= 0, which can only happen if avctx->height <= 0, which is validated elsewhere. Doesn't hurt to still initialize it though. CC: libav-stable@libav.org Bug-Id: CID 732296	10 years ago

Christophe Gisquet	0e8bfd3c93	avcodec/tiffenc: properly compute packet size The bytes per row is a better indication of it. Helps resolving ticket #3874 by fixing ffmpeg's encoder and transforming the issue in a issue with non-compliant decoders. ffmpeg's one is ok, but unfortunately, many others aren't handling correctly unusual chroma samplings.
