Clément Bœsch	e065e8a4ea	lavc/gif: crop image when possible. Increase compression when pictures are similar. -f lavfi testsrc=300: 61M -> 21M	12 years ago
Clément Bœsch	635389ccfa	Cleanse GIF muxer and encoder. This commit removes the badly duplicated code between the encoder and the muxer. That may sound surprising, but the encoder is now responsible from the encoding of the picture when muxing to a .gif file. It also does not require anymore a manual user intervention such as a -pix_fmt rgb24 to work properly. To summarize, output gif are now easier to generate, code is saner and simpler, and files are smaller (thanks to the lzw encoding which was unused so far with the default .gif output). We can certainly make things even better, but this is the first step. FATE is updated because of the output being produced by the encoder and not the muxer (no lzw in the muxer), and in the seek test only the size mismatches. Fixes Ticket #2262	12 years ago
Diego Biurrun	ac9362c5d9	Move misplaced file author information where it belongs	12 years ago
Paul B Mahol	9648e1495b	lavc/gif: remove some obsolete/irrelevant chunks Some code was copy pasted from muxer, which still have same comments but unlike encoder they are still relevant to muxer. Signed-off-by: Paul B Mahol <onemda@gmail.com>	12 years ago

Piotr Bandurski	e03ddbcd91	gifenc: support resolutions up to 65535x65535 Maybe someone can add a check in the second gif encoder (rgb24), because I'm not sure where it should be added. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago

Carl Eugen Hoyos	0cc9949ead	Mark one colour as transparent in the gif image encoder if the input palette contains at least one colour that is more than 50% transparent. Fixes ticket #715.	13 years ago
Anton Khirnov	ec6402b7c5	lavc: use designated initialisers for all codecs. It's more readable and less prone to breakage.	13 years ago
