Nicolas George	9de731e9d0	lavfi/sink_buffer: implement libav compatibility API. Implement av_buffersink_read() and av_buffersink_read_samples() for ffmpeg's version of buffersink. With this change, avconv linked against ffmpeg's libraries passes the same number of tests whether it uses ffbuffersink or buffersink_old.	12 years ago
Nicolas George	8e1f063efc	lavfi: enable buffersinks unconditionally. They are part of the public API. Their libav compatibility counterpart are already enabled unconditionally.	12 years ago
Anton Khirnov	11d1ca4b2c	Use avcodec_free_frame() to free AVFrames.	12 years ago
Stefano Sabatini	740c995288	lavfi: add asendcmd and sendcmd filters	12 years ago
Stefano Sabatini	7fe1ecefe1	lavfi/hue: simplify/fix setting logic in set_options() Parse expression only when a new value is explicitly specified. In particular, avoid double free in case an old expression value is cached, it is set in the context, it is freed as the old value, and finally the pointer stored in the context is freed again when the filter is released.	12 years ago
Andrew Wason	225efccefc	lavfi/buffersink: fix check on pixel_fmts in the opaque parameter Fix programmatic selection of accepted pixel formats. Signed-off-by: Stefano Sabatini <stefasab@gmail.com>	12 years ago
Loren Merritt	1b1b902e2c	hqdn3d: Fix out of array read in LOWPASS Fixes ticket1752 Commit message by commiter Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Stefano Sabatini	3aa1b53256	lavfi/hue: set to NULL freed pointers Possibly safer.	12 years ago
Stefano Sabatini	31aa5b1a78	lavfi/hue: fix crash when resetting the saturation expression Previously when saturation was reinited, the old value was freed when setting options, and freed again in PARSE_EXPRESSION().	12 years ago
Michael Niedermayer	3dc24600ba	vsrc_testsrc: Fix case without a specified duration Fixes regression since `98f753ec51` Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Clément Bœsch	2f39d7ff3f	lavfi/select: make lavc dependency optional.	12 years ago
Stefano Sabatini	98f753ec51	lavfi/testsrc: increase precision of the duration parameter Compute duration in microseconds, rather than in timebase units. Decrease approximation errors.	12 years ago

Michael Niedermayer	f5326dc68e	bavfilter/filtfmts: fix type for channel layouts Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Clément Bœsch	b89c16e73e	lavfi/select: make sure avctx is set before closing it. This avoid a crash when the filter fails before config_input(), typically with a syntax error in the next filter: select=gt(scene\,.4),select=fail	12 years ago
Anton Khirnov	e3496e5dbe	avfiltergraph: silence an uninitialized variable warning The warning is: libavfilter/avfiltergraph.c: In function ‘avfilter_graph_config’: libavfilter/avfiltergraph.c:528:9: warning: ‘best_idx’ may be used uninitialized in this function [-Wuninitialized] libavfilter/avfiltergraph.c:479:13: note: ‘best_idx’ was declared here Initialize it to an invalid value and add an assert that it's properly set later.	12 years ago
Anton Khirnov	4e48aa8656	buffersrc: add const to the AVFrame* argument of av_buffersrc_write_frame()	12 years ago
Mans Rullgard	1fce361d70	lavfi: replace empty input/output lists with null pointers Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
Clément Bœsch	74434d3bfe	lavfi/ass: mark ass_libavfilter_log_level_map as static const.	12 years ago
Hendrik Leppkes	e3a1eb9edf	af_pan: Fix sscanf formats to work with buggy sscanf implementations Some implementations of sscanf do not handle a space before a trailing %n properly. As an example, MSVC's does this for the second insatnce in this patch, for an input of "0x3:c0=c1:c1=c0": 1) Match the final "c0" or "c1". 2) Realize it's at the end of the string. 3) Check for %n. 4) There is no %n, but a space instead. 5) Leave 'len' unitilialized. So, move it out of the sscanf format strings, and call skip_spaces instead. This bug does not affect skip_spaces since %n is the first and only formatting string.

Nicolas George	c262ddb8c5	lavfi: set sample_rate in the default allocator.	12 years ago
Nicolas George	b5bea2f960	lavfi/aresample: set buffer properties after copy. The aresample filter changes the format, layout and/or sample rate, it can not copy them blindly from its input. Related to trac ticket #1671.	12 years ago

Clément Bœsch	7b56dddd56	lavfi/amerge: fix input pad name behaviour. This fixes two problems: - the invalid pad.name stack pointer after init() ends - the duplicated name for all inputs	12 years ago
Stefano Sabatini	206c34e17d	lavfi/setpts: set SAMPLE_RATE to NAN when input is no audio Should be more robust/consistent.	12 years ago
Stefano Sabatini	722762f7e1	lavfi/setpts: add FRAME_RATE constant Useful for dealing with constant frame-rate video.	12 years ago

Stefano Sabatini	a4cb0af945	lavfi: drop deprecated and pointless avfilter_default_end_frame() function Fix warning when compiling boxblur. While this is technically a major API break, practically there will be no one using that function since the filtering API is mostly private, so that function alone is not usable.	12 years ago

Anton Khirnov	91a84a5247	af_asyncts: check return value from lavr when flushing. Fixes an infinite loop on flush when avresample_get_delay() still reports some samples but avresample_convert() doesn't return any data.	12 years ago

Stefano Sabatini	fd5293d216	lavfi/tinterlace: set inlink->cur to NULL, since it is stored internally If not set to NULL, the reference is freed by ff_end_frame(), and later accessed in end_frame() by the filter code, causing a crash.	12 years ago
