Diego Biurrun	fbd1f7639d	af_asyncts: Use llabs instead of labs for 64-bit variable libavfilter/af_asyncts.c:212:9: warning: absolute value function 'labs' given an argument of type 'int64_t' (aka 'long long') but has parameter of type 'long' which may cause truncation of value [-Wabsolute-value]	9 years ago

Anton Khirnov	16a4a18db0	af_asyncts: fix offset calculation delta is in samples, not bytes. Also the sample format is not guaranteed to be planar. CC:libav-stable@libav.org	12 years ago

Jindřich Makovička	20a8ee3061	af_asyncts: fix compensation and PTS monotonicity This patch improves af_asyncts behavior on streams with bogus PTS, which are either non-monotonic, or contain PTS jitter, and trigger the non-monotonicity error. With this patch, af_asyncts is able to correct these streams and avoid the error. Firstly, it fixes resample compensation calculation by supplying proper units to avresample_set_compensation (sample count per second instead of sample count per some arbitrary frame size). Also, the calculation of the compensation itself is fixed - delta is proportional to an adjustment of the compensation, not the compensation itself. Ideally, the compensation should converge to a value that keeps delta at zero. To be able to deal with sources with PTS jitter even without resampling, small PTS errors are adjusted, so the output frames do not overlap. Finally, one more monotonicity check is added. The FATE reference changes because now there is 8 less samples of silence because of the pts jitter. Signed-off-by: Jindřich Makovička <makovick@gmail.com>	12 years ago
Anton Khirnov	7e350379f8	lavfi: switch to AVFrame. Deprecate AVFilterBuffer/AVFilterBufferRef and everything related to it and use AVFrame instead.	12 years ago

Justin Ruggles	c143de40c3	asyncts: fix the asyncts behavior when using the first_pts option Currently it will do padding, but it does not properly handle start-of-stream trimming as documented.	12 years ago
Justin Ruggles	8083332c2d	asyncts: use clipped delta value when setting resample compensation The max_comp option is supposed to limit maximum compensation, but currently the clipped value is not actually used.	12 years ago
Justin Ruggles	f266486b2e	asyncts: fix flushing of final samples at EOF	12 years ago
Anton Khirnov	565e4993c6	lavfi: merge start_frame/draw_slice/end_frame Any alleged performance benefits gained from the split are purely mythological and do not justify added code complexity.	12 years ago
Mans Rullgard	568c70e79e	lavfi: convert input/ouput list compound literals to named objects A number of compilers, for example those from TI and IBM, choke on these initialisers. The current style is also quite ugly. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
Anton Khirnov	e7ba5b1de0	lavr: change the type of the data buffers to uint8_t**. This is more consistent with what the rest of Libav does. This breaks API.	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

Anton Khirnov	4d7adec8bd	AVOptions: store defaults for INT64 options in int64 union member. Double does not have enough precision to represent all int64 numbers exactly.	12 years ago

Justin Ruggles	be51e589cd	af_asyncts: avoid overflow in out_size with large delta values	12 years ago
Justin Ruggles	70d71b5801	af_asyncts: add first_pts option This allows for padding/trimming at the start of stream. By default, no assumption is made about the first frame's expected pts, so no padding or trimming is done.	12 years ago
Anton Khirnov	cd99146253	lavfi: add error handling to filter_samples().	13 years ago
Anton Khirnov	6f834293d3	af_asyncts: fix request_frame() behavior. Make sure that an output frame has really been produced before returning 0.	13 years ago
Anton Khirnov	a5e8c41c28	lavfi: remove 'opaque' parameter from AVFilter.init() It is not used in any filters currently and is inherently evil. If passing binary data to filters is required in the future, it should be done with some AVOptions-based system.	13 years ago
Anton Khirnov	803391f719	lavfi: remove request/poll and drawing functions from public API on next bump They are only useful inside filters and we don't allow user filters for now.	13 years ago
Anton Khirnov	f297dd3812	asyncts: reset delta to 0 when it's not used. Fixes an invalid write.	13 years ago
Anton Khirnov	9f26421b0b	lavfi: add asyncts filter.	13 years ago
