Eugene Dzhurinsky	09f59d6adf	avformat/gif: Do not write GIF89a header if loop is set to -1. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	8870cf7c0e	avformat/gif: remove unneeded doxygen comment Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Clément Bœsch	67cc31d6c7	lavf/gif: add final_delay option.	12 years ago
Clément Bœsch	6189ff3679	lavf/gif: avoid forward declaration.	12 years ago
Clément Bœsch	a7c5b7a676	lavf/gif: correct the delay after the first frame. To define accurately the delay between two frames, it is necessary to have both available. Before this commit, the first frame had a delay of 0; while in practice the problem is not visible in most situation, it is problematic with low frame rate and large scene change. This commit notably fixes output generated with commands such as: ffmpeg -i big_buck_bunny_1080p_h264.mov -vf "select='gt(scene,0.4)',scale=320:-1,setpts=N/TB" -frames:v 5 -y out.gif Also, to avoid odd loop delays, the N-1 delay is duplicated for the last frame.	12 years ago
Clément Bœsch	7e57adb464	lavf/gif: fix timing. pkt->duration can not be used since the values are only based on frame rate.	12 years ago
Clément Bœsch	13478b270a	gif: use only one graphic control extension block per image. The encoder now doesn't produce any extra graphic control extension block anymore. Only the image is encoded, and the muxer writing its own GCE containing notably the timing information now includes the optional palette transmitted through packet side data. This commit avoid setting clashes between the two GCE, and reduce the size of the generated file with pal8 output.	12 years ago
Clément Bœsch	9db1c6455e	lavf/gif: support only GIF codec.	12 years ago
Clément Bœsch	01367b0fca	lavf/gif: merge gif_write_{packet,video}. Avoid a pointless split.	12 years ago
Clément Bœsch	b7a3f14360	lavf/gif: trim unnecessarily long netscape ext code. Extension description comments are now placed along the avio calls, the always defined macro removed, and the always true loop_count check as well (loop option is bound to 0-65535).	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
Clément Bœsch	8de9bb6e5e	lavf: remove some flushing in write_packet muxers callbacks. Since `4f112a8e3`, this is not necessary anymore. Also, it allows to actually disable the flushing.	12 years ago
Diego Biurrun	ac9362c5d9	Move misplaced file author information where it belongs	12 years ago
Anton Khirnov	716d413c13	Replace PIX_FMT_* -> AV_PIX_FMT_*, PixelFormat -> AVPixelFormat	12 years ago
Anton Khirnov	3b4bb19e63	lavf: flush the output AVIOContext in av_write_trailer(). This is consistent with stdio and is what we want to do in all cases. Fixes a bug in the voc muxer which didn't flush in write_trailer() previously. This is the cause of the change in the test results.	12 years ago

Diego Elio Pettenò	66355be3c3	Prefix all _demuxer, _muxer, _protocol from libavformat and libavdevice. This also lists the objects from those two libraries as internal (by adding the ff_ prefix) so that they can then be hidden via linker scripts. (cherry picked from commit `c6610a216e`)	14 years ago
