Vittorio Giovara	4b6b1082a7	lavc: Deprecate avctx.me_method This option is extremely codec specific and only a few codecs employ it. Move it to codec private options instead: mpegenc family supports only 3 values, xavs and x264 use 5, and xvid has a different metric entirely.

Steve Lhomme	9b4b96c0de	force WINAPI_FAMILY to WINAPI_FAMILY_DESKTOP_APP to be able to use dxva.h The struct definitions in dxva.h, which are necessary in order to actually use d3d11va, are hidden when WINAPI_FAMILY targets Windows Phone or WindowsRT. Building with WINAPI_FAMILY=WINAPI_FAMILY_DESKTOP_APP is disallowed when targeting ARM. ("Compiling Desktop applications for the ARM platform is not supported.") So we set _CRT_BUILD_DESKTOP_APP to 0 to tell the runtime not to detect some issues with this mismatching. The same tweaks to detect if the API is available is done in dxva2_internal.h when compiling each DXVA2/D3D11VA decoders. Signed-off-by: Martin Storsjö <martin@martin.st>	10 years ago

Anton Khirnov	22522d9c2c	qsvdec: fix a memleak of async_fifo init() is called whenever format changes, so current code would leak the fifo in this case.	10 years ago
Anton Khirnov	aa9d15d89b	qsvdec: avoid an infinite loop with no consumed data and no output This is triggerable with the HEVC decoder. It is unclear yet whether the bug is in the calling code or the MSDK, but it seems better to check for this in any case.	10 years ago

Janne Grunau	f56d8d8dd7	h264: aarch64: intra prediction optimisations	10 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>	10 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>	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

Vittorio Giovara	91767360d8	a64multienc: Do not entangle coded_frame This change (and the following ones of the same kind) is mainly to simplify wrapping this section with an #if FF_API block later on. No functional changes are applied, the fields of the context coded_frame fields are directly initialized, instead of keeping a reference to the coded_frame itself.

Henrik Gramner	a344e5d094	x86: bswapdsp: Don't treat 32-bit integers as 64-bit The upper halves are not guaranteed to be zero in x86-64. Also use `test` instead of `and` when the result isn't used for anything other than as a branch condition, this allows some register moves to be eliminated.
