Vittorio Giovara	7c6eb0a1b7	lavc: AV-prefix all codec flags Convert doxygen to multiline and express bitfields more simply. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	10 years ago
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.

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

Derek Buitenhuis	4719040cd1	libx264: Define X264_API_IMPORTS on MSVC/ICL libx264 has a few data exports which require X264_API_IMPORTS to be defined if we link to libx264 dynamically on Windows. In a similar fashion to how we handle our compat snprintf implementation, if we define it all the time, the compiler will first try and link to __imp_x264_symbol_name, and failing that, as in the case of a static libx264, will attempt to link to the non-prefixed symbol, which has already been pulled in by other x264 functions' object files.

John Van Sickle	2f325a6fd4	libx264: change i_qfactor to use x264cli's default This also allows libx264 to modify its i_qfactor value when using the "-tune" setting. Previously it had a static value of 1.25 Signed-off-by: Anton Khirnov <anton@khirnov.net>	12 years ago

Martin Storsjö	57facb73ab	libx264: Don't leave max_b_frames as -1 if the user didn't set it max_b_frames is initialized to -1 for libx264, to allow distinguishing between an explicit user set 0 and a default not touched 0 (see `bb73cda2`). If max_b_frames is left as -1, this affects dts generation (where expressions like max_b_frames != 0 are used), so make sure it is left at the default 0 after the libx264 init function returns. This avoids unnecessarily producing dts != pts when using profile=baseline. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Janne Grunau	b4d44a45f9	threads: introduce CODEC_CAP_AUTO_THREADS and add it to libx264 Some external codecs have their own code to determine the best number of threads.
