Luca Barbato	6b2b26e7af	dds: Decode using optimal slices sizes Enjoy some cache locality and use less threads. About the same speedup provided to HAP. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	9 years ago
Luca Barbato	977105407c	hap: Decode using optimal slices sizes Enjoy some cache locality and use less threads. About 5x speedup (from 60ms to 12ms to decode a 4k frame). Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	9 years ago
Luca Barbato	219b39a71a	parseutil: Use non ambiguous aliases for uhd uhd1 and uhd2 would be ambigous.	9 years ago
Janne Grunau	9ed6f9a17c	arm: use a local label instead of the function symbol in ff_prefetch_arm Avoids a relocation which might end out of range for thumb2. Reported-By: Ludovic Fauvet <etix@videolan.org> Bug-Id: https://bugs.webkit.org/show_bug.cgi?id=137022 CC: libav-stable@libav.org	9 years ago
Janne Grunau	f56d8d8dd7	h264: aarch64: intra prediction optimisations	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	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.

Anton Khirnov	6b15874fc2	af_resample: do not touch the timestamps if we are not resampling This filter currently assumes that the input audio is continuous and does some timestamps manipulation based on this assumption. This is unnecessary if we are only converting the channel layout or the sample format, without resampling. In such a case, just leave the timestamps as they are.	9 years ago
Anton Khirnov	6d592fbd0d	avconv: split creating and (re-)configuring complex filtergraphs The current code is less than straightforward due to the fact that output streams can be created based on filtergraph definitions. This change should make the code simpler and more readable. It will also be useful in the future commits.	9 years ago
Anton Khirnov	be101bc1e3	avconv: create the complex filtergraphs earlier Since global options are processed before all the other options now, we do not have to try creating the complex filtergraphs several times anymore, it is enough to do it once after the input files are opened.	9 years ago

Anton Khirnov	59245e0c5e	avconv: set the encoding/decoding_needed flags earlier This will be useful in the following commits.	9 years ago
Anton Khirnov	56c2f37727	avconv: drop update_sample_fmt() There is only one decoder left that supports this (libopus, which is not used by default since we have a native one) and this code goes against the avconv design, since it propagates information back from the encoder to decoder.	9 years ago

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.
