Clément Bœsch	e1b35bdde2	lavc/gif: add flag to enable transparency detection between frames. While this is not always optimal, in practice most of the common cases are. ffmpeg -i big_buck_bunny_1080p_h264.mov -ss 45 -vf scale=320:160 -gifflags -transdiff -frames:v 50 -y bbb-notrans.gif ffmpeg -i big_buck_bunny_1080p_h264.mov -ss 45 -vf scale=320:160 -gifflags +transdiff -frames:v 50 -y bbb-trans.gif -rw-r--r-- 1 ubitux ubitux 1.1M Apr 19 19:00 bbb-notrans.gif -rw-r--r-- 1 ubitux ubitux 378K Apr 19 19:00 bbb-trans.gif	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	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

Michael Niedermayer	b3c3996212	avcodec: rename prores encoders Using the first names of authors sounds somewhat unprofessional and might be considered offensive which is not intended. The new names use the initials of the authors due to simplicity and the possibility to apply it consistently without the need to find political correct names for each future case where alternative codecs might exist. Also its shorter ... If someone has a better idea, like maybe 2 random letters and people prefer it then iam happy to switch to that ...

Nicolas George	0884d04dc3	lavc: fix recoded subtitles end. Text subtitles packets are not 0-terminated (and if they are, it is handled by the recoding process since 0 is a valid Unicode code point). The terminating 0 would overwrite the last payload octet. OTOH, packets must be 0-padded. Fix a problem reported in trac ticket #2431.	12 years ago
