* drawtext: manage memory allocation betterLuca Barbato2011-12-03
| | | | | Call dtext_prepare_text as early as possible Do not draw if the memory allocation failed
* drawtext: refactor draw_textLuca Barbato2011-12-03
| | | | Split the memory allocation from the actual drawing.
* Make channel layout masks unsignedMans Rullgard2011-11-25
| | | | | | | | | | It makes more sense for a bit mask to use an unsigned type. The change should be source and binary compatible on all supported systems, hence micro version bump. Fixes a few invalid shifts. Signed-off-by: Mans Rullgard <mans@mansr.com>

* lavfi: add rgbtestsrc source, ported from MPlayer libmpcodecsStefano Sabatini2011-10-19
| | | | | | | | | | | | The licence was changed from GPL to LGPL with explicit approval from the original author. See thread: Subject: [FFmpeg-devel] [PATCH] lavfi: add rgbtestsrc source, ported from MPlayer libmpcodecs Date: Mon, 11 Jul 2011 16:32:41 +0200 Signed-off-by: Anton Khirnov <anton@khirnov.net>

* lavfi: port libmpcodecs delogo filterStefano Sabatini2011-10-17
| | | | | | The ported filter supports named option parsing and more YUV formats. Signed-off-by: Anton Khirnov <anton@khirnov.net>
* lavfi: port boxblur filter from libmpcodecsStefano Sabatini2011-10-17
| | | | | | | | | | With the following additions: * support to gray format * support to yuva420p format * parametric luma/chroma/alpha radius * consistency check on the radius values, avoid crashes with invalid values Signed-off-by: Anton Khirnov <anton@khirnov.net>
* lavfi: add negate filterStefano Sabatini2011-10-17
| | | | | | This filter is a simple wrapper around the LUT filter. Signed-off-by: Anton Khirnov <anton@khirnov.net>
* lavfi: add LUT (LookUp Table) generic filtersStefano Sabatini2011-10-17

* vf_unsharp: set default chroma size value to 5x5Stefano Sabatini2011-09-29
| | | | | | | The previous default value 0x0 was not good, since it is not even valid. Signed-off-by: Anton Khirnov <anton@khirnov.net>
* vf_unsharp: fix out-of-buffer readStefano Sabatini2011-09-29
| | | | | | | | | | | | In apply_unsharp(), when y is >= height, prevent out-of-buffer reading from src, read from the last buffer line in src2 instead. The check was implemented in the original unsharp libmpcodecs code and lost in the port. This also fixes output discrepancy between the two filters. Signed-off-by: Anton Khirnov <anton@khirnov.net>
* vf_unsharp: store hsub/vsub in the filter contextStefano Sabatini2011-09-28
| | | | | | Also drop obfuscating CHROMA_WIDTH/HEIGHT macros. Signed-off-by: Anton Khirnov <anton@khirnov.net>
* vf_unsharp: adopt a more natural order of params in apply_unsharp()Stefano Sabatini2011-09-28
| | | | Signed-off-by: Anton Khirnov <anton@khirnov.net>
* vf_unsharp: rename method "unsharpen" to "apply_unsharp"Stefano Sabatini2011-09-28
| | | | | | | More consistent with the original libmpcodecs code, and the name "unsharpen" was confusing. Signed-off-by: Anton Khirnov <anton@khirnov.net>
* vf_scale: apply the same transform to the aspect during init that is applied ↵Michael Niedermayer2011-09-28
| | | | | | per frame Signed-off-by: Anton Khirnov <anton@khirnov.net>
* vf_pad: fix "vsub" variable value computationStefano Sabatini2011-09-28
| | | | | | It was shifting 2 rather than 1, +10l. Signed-off-by: Anton Khirnov <anton@khirnov.net>
* vf_scale: add a "sar" variableStefano Sabatini2011-09-28
| | | | | | | Also create a "dar" alias for the "a" variable, for avoiding possible confusion between dar/sar. Signed-off-by: Anton Khirnov <anton@khirnov.net>
* lavfi: fix realloc size computation in avfilter_add_format()Stefano Sabatini2011-09-28
| | | | | | | | | | | | | Replace sizeof((*avff)->formats) with sizeof(*(*avff)->formats) as the size of the array element is given by the pointed element rather than by its pointer. In particular fix computation with the pending patch when sizeof(int64_t) != sizeof(int64_t *). Signed-off-by: Anton Khirnov <anton@khirnov.net>

* vf_yadif: correct documentation on the parity parameterStefano Sabatini2011-09-21
| | | | | | | 0 is top-field-first, 1 is bottom-field-first, not the other way around. Signed-off-by: Anton Khirnov <anton@khirnov.net>

* vsrc_color: set output pos values to -1Stefano Sabatini2011-09-19
| | | | | | -1 is more correct than 0, as the position in the file is undefined. Signed-off-by: Anton Khirnov <anton@khirnov.net>

* AVOptions: deprecate av_opt_set_defaults2Anton Khirnov2011-09-07
| | | | | | 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.
