Stefano Sabatini	d2752ef061	lavfi/overlay: add process_command callback	12 years ago
Stefano Sabatini	006e20bd36	lavfi/overlay: add enable expression This expression is useful to enable/disable overlaying on the fly. Note that this can't be easily done relying on the filtergraph structure, since this implies caching issues or a null frame overlaying in the best case, which is better avoided for performance and convenience reasons.	12 years ago
Stefano Sabatini	cc3edd99a6	lavfi/overlay: add dynamic expression evaluation support Add support for dynamic x, y expressions evaluation. Also add support for an evaluation mode which allows to disable per-frame evaluation, so that there is no speedloss in case the expression does not depend on frame variables.	12 years ago

Derek Buitenhuis	9db706206d	doc: Consistently use 'filtergraph' We used to use 'filtergraph' or 'filter graph' randomly. 'filtergraph' was chosen due to having 57 occurrences in the documentation, whereas 'filter graph' had only 19. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	12 years ago

Timothy Gu	874173002e	doc/filters: fix width/height typo in crop filter. Signed-off-by: Clément Bœsch <ubitux@gmail.com>	12 years ago
Clément Bœsch	2d66fc543b	lavfi/gradfun: fix rounding in MMX code. Current code divides before increasing precision. Also reduce upper bound for strength from 255 to 64. This will prevent an overflow in the SSSE3 and MMX filter_line code: delta is expressed as an u16 being shifted by 2 to the left. If it overflows, having a strength not above 64 will make sure that m is set to 0 (making the mmdelta >> 14 expression void). A value above 64 should not make any sense unless gradfun is used as a blur filter. Signed-off-by: Anton Khirnov <anton@khirnov.net>	12 years ago
