Nicolas George	aa1246ea42	lavfi: unify src_buffer and buffersrc. Most of the code is moved to buffersrc.c to help Git see the similarities. src_buffer.c still contains the obsolete compatibility functions. The format change detection code was removed as it has been implemented directly in ffmpeg. It can easily be brought back from the history.	13 years ago

Michael Niedermayer	13fdb35535	src_buffer: fix query_formats_audio() Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Stefano Sabatini	4d4098da00	lavfi: drop planar/packed negotiation support The planar/packed switch and the packing_formats list is no longer required, since the planar/packed information is now stored in the sample format enum. This is technically a major API break, possibly it should be not too painful as we marked the audio filtering API as unstable.	13 years ago
Michael Niedermayer	47aae2bc2e	lavfi: switch to _alt functions Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Clément Bœsch	4522df52aa	lavfi: remove audio.h include from avfilter.h. avfilter.h is a public header and the unexported audio.h header contains only internal prototypes.	13 years ago

Nicolas George	317b2b7e92	lavfi: remove av_buffersrc_buffer. It is no longer used anywhere. Furthermore, the header it was declared in was not installed, so it can not be considered part of the public API.	13 years ago
Nicolas George	7bac2a78c2	src_buffer: implement av_buffersrc_add_frame. It supersedes av_vsrc_buffer_add_frame and handles both audio and video.	13 years ago

Nicolas George	cc14cdec45	src_buffer: move buffer copy in a separate function. This will make merging with the audio part easier.	13 years ago
Nicolas George	f94b150a03	src_buffer: move format change check in a separate function. This will make merging the check with the audio part easier.	13 years ago
Nicolas George	3985ec0ee6	src_buffer: introduce av_buffersrc_add_ref(). This function merges the features of av_vsrc_buffer_add_video_buffer_ref() and av_buffersrc_buffer().	13 years ago
Nicolas George	f1b82099cd	src_buffer: add forgotten avfilter_unref_buffer.	13 years ago

Nicolas George	2d6522bab0	vsrc_buffer: count the number of failed requests.	13 years ago
Nicolas George	f75ee4031e	vsrc_buffer: return EAGAIN if no frame is available. This is not an erroneous condition, do not print a warning.	13 years ago
Michael Niedermayer	5cd460ba63	vsrc_buffer: fix null ptr segfault Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Anton Khirnov	7bf9e3391f	vsrc_buffer: fix check from `7ae7c41`. The user submitted variable in this function is frame, not buf.	13 years ago
Anton Khirnov	7ae7c41413	vsrc_buffer: allow using a NULL buffer to signal EOF.	13 years ago

Diego Biurrun	3dc99a18d4	cosmetics: drop some pointless parentheses	13 years ago
Anton Khirnov	e1d9dbf2d4	lavfi: add a new function av_buffersrc_buffer(). It can be used to directly pass a AVFilterBufferRef to lavfi, avoiding a memcpy.	13 years ago
Stefano Sabatini	1c9e340d35	lavfi: add avfilter_copy_frame_props() avfilter_copy_frame_props() avoids code duplication and increases robustness.	14 years ago
Reimar Döffinger	5af7daabc4	Mark AVFilterPad[] compound literals as const. GCC 4.6.2 at least still seems to fail to put them in .rodata though, see also http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37303 Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	13 years ago

Stefano Sabatini	27bcf55f45	vsrc_buffer: add flags param to av_vsrc_buffer_add_video_buffer_ref The new flags parameter allows to specify if the video ref to add should overwrite the cache, if the flag is not set vsrc_buffer will complain and abort; otherwise it will clean the already cached video ref before to overwrite it, thus avoiding a leak.	14 years ago
Stefano Sabatini	9e66b64c36	vsrc_buffer: propagate error code in av_vsrc_buffer_add_frame() Propagate av_vsrc_buffer_add_video_buffer_ref() error code rather than return 0.	14 years ago
Stefano Sabatini	cf06e3e4dd	vsrc_buffer: return an error code if no frames are available Also decrease the log level of the corresponding message to WARNING, since the error is not fatal.	14 years ago
Stefano Sabatini	f7053dc41a	vsrc_buffer: tweak error message in init() Change: Expected 7 arguments, but only %d found in '%s'\n to: Expected 7 arguments, but %d found in '%s'\n as the user may provide more than 7 arguments, in that case the error is not misleading. Signed-off-by: Anton Khirnov <anton@khirnov.net>	14 years ago
Stefano Sabatini	c000a9f783	vsrc_buffer: add av_vsrc_buffer_add_frame() The new function is a wrapper around av_vsrc_buffer_add_video_buffer_ref(), and allows to simplify the act of pushing AVFrame data to the source buffer.	14 years ago
Stefano Sabatini	50764e19a8	vsrc_buffer: make the source accept sws_param in init Avoid the need of two distinct av_vsrc_add_video_buffer_ref* functions. Simplify the interface.	14 years ago
