Anton Khirnov	b3dd30db0b	lavfi: pass the hw frames context through the filter chain	9 years ago
Anton Khirnov	c084d6d2cf	buffersrc: default SAR to 0 (unknown) rather than 1 It makes more sense to not claim anything about the SAR if we don't know anything. No changes in the FATE tests, since this is what avconv ends up doing anyway.	9 years ago
Anton Khirnov	fb25d99b0a	buffersrc: do not discard the error from ff_filter_frame()	9 years ago
Nicolas George	61fb67dcb2	buffersrc: accept the frame rate as argument. (cherry picked from ffmpeg commit `9ca440679d`) Signed-off-by: Anton Khirnov <anton@khirnov.net>	9 years ago
Ganesh Ajjanagadde	6aaac24d72	avfilter/all: propagate errors of functions from avfilter/formats Many of the functions from avfilter/formats can return errors, usually AVERROR(ENOMEM). This propagates the return values. All of these were found by using av_warn_unused_result, demonstrating its utility. Tested with FATE. I am least sure of the changes to avfilter/filtergraph, since I don't know what/how reduce_format is intended to behave and how it should react to errors. Fixes: CID 1325680, 1325679, 1325678.

Hendrik Leppkes	779e6c2b98	lavfi: add attribute_align_arg to all public entry points Previously it was partly only added to central functions called internally, however if GCC would inline these into the public fuction, the alignment attribute would not take effect.

Hendrik Leppkes	20c86571cc	lavfi: let gcc realign the stack on public graph driving functions The functions which actually drive the filter graph by pushing frames through it need to ensure an aligned stack for SIMD functions.

Nicolas George	e3e6aa7afb	lavfi/buffersrc: fix failed requests count. The line was lost during the AVFrame transition. It causes programs relying on the failed requests count, especially ffmpeg, to add frames to the wrong input. Fix trac ticket #2467.	12 years ago

Nicolas George	b0012de420	lavfi/buffersrc: implement flags. The PUSH flags is necessary for efficient scheduling; otherwise there is no feedback when adding frames to closed paths. The NO_CHECK_FORMAT is a small optimization that does not cost much to implement. The KEEP_REF flag maps to the add/write distinction in the fork's API.	12 years ago

Nicolas George	01649c79c8	lavfi/buffersrc: set channel layout if it is known. If buffersrc was configured for frames with an unknown layout, the incoming frames will have channel_layout = 0. If the format negotiation has selected a known (and compatible) channel layout for the link, the frame is assumed to have that layout, the field must be set before injecting the frame in the filters.	12 years ago
