Andreas Rheinhardt	30c802f3ae	avcodec/dpxenc: Remove redundant pixel format check ff_encode_preinit() already checked the pixel format via AVCodec.pix_fmts. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	3 years ago
Andreas Rheinhardt	ed6549887a	avcodec/encoders: Remove redundant setting of AV_PKT_FLAG_KEY It is now set generically for all those encoders whose corresponding AVCodecDescriptor has the AV_CODEC_PROP_INTRA_ONLY. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	3 years ago
Andreas Rheinhardt	ae7a7dc458	avcodec/dpxenc: Avoid copying packet data, allow user-supplied buffers When the packet size is known in advance like here, one can avoid an intermediate buffer for the packet data; this also makes it easy to allow user-supplied buffers. Only one thing needed to be changed: One can no longer use a pointer to uint16_t for the destination buffer because its alignment is unknown.

Andreas Rheinhardt	a80b3e5e0e	avcodec/dpxenc: Mark encoder as init-threadsafe Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>	4 years ago
Andreas Rheinhardt	a247ac640d	avcodec: Constify AVCodecs Given that the AVCodec.next pointer has now been removed, most of the AVCodecs are not modified at all any more and can therefore be made const (as this patch does); the only exceptions are the very few codecs for external libraries that have a init_static_data callback.

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
Michael Niedermayer	8edc17b639	avcodec/dpxenc: implement write16/32 as functions Fixes undefined behavior and segfault Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Zoltan Kovacs	4843a9c74f	dpx: always write the image offset According to the DPX file format description found at http://www.fileformat.info/format/dpx/egff.htm the ImageElement part of the GenericImageHeader also contains an an offset to the real image data beside the same member that can be found in the GenericFileHeader. Libav keeps this member empty (=0) while some applications expects it to be filled properly. FATE test updated accordingly.
