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	9d0bfc5052	lavfi: make AVFilterPad opaque after two major bumps. It will allow adding new fields to it without ABI breaks.	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	b74a1da49d	lavfi: make formats API private on next bump. It is only useful inside filters and we don't allow user filters for now.	13 years ago
Anton Khirnov	c04c533f62	lavfi: remove avfilter_null_* from public API on next bump. Those functions are only useful inside filters. It is better to not support user filters until the API is more stable.	13 years ago
Alex Converse	b0f29db5c2	Mark mutable static data const where appropriate.	13 years ago
Andrey Utkin	e496c45d9b	drawtext: add 'fix_bounds' option on coords fixing Before, drawtext filter deliberately altered given text coordinates if text didn't fully fit on the picture. This breaks the use case of scrolling large text, e.g. movie closing credits. Add 'fix_bounds', to make it usable in such cases (by setting its value to 0). Default behavior is not changed, and non-fitting text coords are fixed. Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Andrey Utkin	2b43dfce36	drawtext: fix text_{w, h} expression vars Before, {text_,}{w,h} vars hadn't got initialized Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Andrey Utkin	e7f0bc8c0f	drawtext: add missing braces around an if() block. Prevents uninitialized read. Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago

Luca Barbato	ec11ff8407	drawtext: manage memory allocation better Call dtext_prepare_text as early as possible Do not draw if the memory allocation failed	13 years ago
Luca Barbato	a2fb4bcb01	drawtext: refactor draw_text Split the memory allocation from the actual drawing.	13 years ago
Diego Biurrun	124e28847b	Remove some stray unnecessary ffmpeg references.	13 years ago
Anton Khirnov	145f741e11	AVOptions: rename FF_OPT_TYPE_* => AV_OPT_TYPE_*	13 years ago
Anton Khirnov	79eff91325	AVOptions: deprecate av_opt_set_defaults2 It's a hack which was created to allow for multiple options with different defaults to refer to same field (e.g. 'b' vs 'ab'). There is no need for it anymore.	13 years ago
