Clément Bœsch	5f9986f597	avformat/gif: use first packet palette as global for PAL8 This will allow the payload in PAL8 packets to not contain 768B of local palette (which is not LZW compressed).	10 years ago
Clément Bœsch	adb9b235b6	avformat/gif: simplify gif_image_write_header() prototype	10 years ago
Diego Biurrun	daf8cf358a	avformat: Don't anonymously typedef structs	10 years ago
Carl Eugen Hoyos	87f2999641	Force gif aspect ratio multiplication to 64bit. Avoids a possible integer overflow.	11 years ago
Carl Eugen Hoyos	45782a98b6	Write aspect ratio when muxing gif.	11 years ago
Clément Bœsch	c37b0daf33	avformat/gif: fix final_delay unit in documentation.	11 years ago
Clément Bœsch	7308439158	lavf: Don't explicitly flush after each written packet in muxers Since `596e5d4783`, this is not necessary anymore. It also allows to actually disable the flushing, improving write performance (but possibly giving worse latency in real-time streaming). Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
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	0a0e6877ff	lavf/gif: remove unused fields.	12 years ago
Clément Bœsch	28f9858c91	lavf/gif: simplify streams type checking.	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

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
