* avcodec: rewrite gif muxing and encodingPaul B Mahol2018-12-13
| | | | | | | | | | | | | | | Now "-c copy" works. Update FATE files. Demuxer only split file into packets, no data is trimmed. Encoder & muxer currently expect completely another format where muxer writes stuff like disposal method which should be really encoder job. With this patch muxer only modifies delay between two packets. Codec copy need to have same behavior between demuxer and muxer to work correctly. Fixes #6640.

| * lavf: replace AVStream.codec with AVStream.codecparAnton Khirnov2016-02-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, AVStream contains an embedded AVCodecContext instance, which is used by demuxers to export stream parameters to the caller and by muxers to receive stream parameters from the caller. It is also used internally as the codec context that is passed to parsers. In addition, it is also widely used by the callers as the decoding (when demuxer) or encoding (when muxing) context, though this has been officially discouraged since Libav 11. There are multiple important problems with this approach: - the fields in AVCodecContext are in general one of * stream parameters * codec options * codec state However, it's not clear which ones are which. It is consequently unclear which fields are a demuxer allowed to set or a muxer allowed to read. This leads to erratic behaviour depending on whether decoding or encoding is being performed or not (and whether it uses the AVStream embedded codec context). - various synchronization issues arising from the fact that the same context is used by several different APIs (muxers/demuxers, parsers, bitstream filters and encoders/decoders) simultaneously, with there being no clear rules for who can modify what and the different processes being typically delayed with respect to each other. - avformat_find_stream_info() making it necessary to support opening and closing a single codec context multiple times, thus complicating the semantics of freeing various allocated objects in the codec context. Those problems are resolved by replacing the AVStream embedded codec context with a newly added AVCodecParameters instance, which stores only the stream parameters exported by the demuxers or read by the muxers.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | 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.

* | Cleanse GIF muxer and encoder.Clément Bœsch2013-04-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
