Luca Barbato	98c9ade985	drawtext: Move the strftime expansion in a separate function Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	10 years ago
Luca Barbato	fe026ba960	drawtext: Drop stray guards There is a fallback for localtime_r and it is in use already. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	10 years ago
Luca Barbato	9b2c57bef5	drawtext: Add an alpha option And document both `draw` and `alpha`. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	10 years ago
Vittorio Giovara	1a3eb042c7	Replace av_dlog with normal av_log at trace level This applies to every library where performance is not critical.	10 years ago
Михаил Муковников	71f29410e7	lavfi: Increase drawtext font size limits Raise the maximum font size to a larger value. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	11 years ago
Martin Storsjö	6b9b42cc55	drawtext: Remove the ifdef for localtime_r If it isn't available in the system, we've got a fallback to the normal localtime function, so normal code can assume it is available as long as time_internal.h is included. Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Luca Barbato	f401792595	vf_drawtext: Do not leak the mmapped textfile And validate its size while at it. CC: libav-stable@libav.org Bug-Id: CID 1244189	11 years ago
Vittorio Giovara	58400ac133	lavfi: name anonymous structs	11 years ago
Luca Barbato	f1b239ec8b	drawtext: Add fontconfig support Introduce the `font` option and make it optional to pass a fontfile. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	11 years ago
Luca Barbato	d68dc3c944	drawtext: Drop pointless header It should be forward compatible with newer freetype.	11 years ago
Anton Khirnov	cd43ca0443	lavfi: do not export the filters from shared objects	12 years ago
Anton Khirnov	3fb29588a2	vf_drawtext: don't leak the expressions.	12 years ago
Anton Khirnov	90d9a2a04c	vf_drawtext: do not reset the frame number in config_input. Frame number should be incremented normally even if the link properties change.	12 years ago
Anton Khirnov	d3735f7ad6	vf_drawtext: use the name 's' for the pointer to the private context This is shorter and consistent across filters.	12 years ago
Anton Khirnov	c43a7ecad9	lavfi: remove now unused args parameter from AVFilter.init	12 years ago
Anton Khirnov	8ec464c61c	vf_drawtext: switch to an AVOptions-based system.	12 years ago
Anton Khirnov	7e350379f8	lavfi: switch to AVFrame. Deprecate AVFilterBuffer/AVFilterBufferRef and everything related to it and use AVFrame instead.	13 years ago
Anton Khirnov	cb45553f57	Remove pointless #undefs of previously forbidden functions.	13 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.	13 years ago
Anton Khirnov	b68aac7ea3	vf_drawtext: do not use deprecated av_tree_node_size	13 years ago
Anton Khirnov	59ee9f78b0	lavfi: do not use av_pix_fmt_descriptors directly.	13 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>	13 years ago
Anton Khirnov	716d413c13	Replace PIX_FMT_* -> AV_PIX_FMT_*, PixelFormat -> AVPixelFormat	13 years ago
Martin Storsjö	e6153f173a	avopt: Store defaults for AV_OPT_TYPE_INT in the i64 union member Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Martin Storsjö	d58dd4b5b5	avopt: Store defaults for AV_OPT_TYPE_FLAGS in the i64 union member Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Martin Storsjö	124134e424	avopt: Store defaults for AV_OPT_TYPE_CONST in the i64 union member Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Martin Storsjö	33e112847d	Add more missing includes after removing the implicit common.h Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Anton Khirnov	d4f89906e3	lavfi: add error handling to end_frame().	13 years ago
Anton Khirnov	e9b992d035	lavfi: add error handling to draw_slice().	13 years ago
Anton Khirnov	ebc8d97481	lavfi: add error handling to start_frame().	13 years ago
Ronald S. Bultje	3db407038e	lavfi: use const for AVFilterPad declarations in all filters.	13 years ago
Anton Khirnov	07bad27810	lavfi: unref AVFilterLink.cur_buf in ff_end_frame(). This reduces code duplication and prevents stale pointers from remaining on the link.	13 years ago
Anton Khirnov	7155763b78	vf_drawtext: don't give up its own reference to the input buffer. Directly forwarding the input buffer to the next filter means that drawtext no longer owns any references to it and thus shouldn't refer to it in any way.	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	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
Diego Biurrun	d4b63054d9	cosmetics: Drop unnecessary parentheses around return values.	14 years ago
Luca Barbato	78212cefe1	drawtext: remove typo It slipped through the last two iterations.	14 years ago
Luca Barbato	f5edfc9e92	drawtext: introduce rand(min, max) Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	14 years ago
Luca Barbato	73585620b8	drawtext: introduce explicit draw/hide variable Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	14 years ago
Luca Barbato	2cf74eca70	drawtext: make x and y parametric Introduce variables "E", "PHI", "PI", "main_w"/"W", "main_h"/"H", "text_w"/"w", "text_h"/"h", "x", "y", "n" and "t" in line with vf_overlay and refactor the code accordingly.	14 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	14 years ago
Luca Barbato	a2fb4bcb01	drawtext: refactor draw_text Split the memory allocation from the actual drawing.	14 years ago
Diego Biurrun	124e28847b	Remove some stray unnecessary ffmpeg references.	14 years ago
