* Gif demuxerVitaliy E Sugrobov2012-11-30
| | | | | | | | | | | | | | | | | | | | | Gif demuxer is capable of extracting multiple frames from gif file. In conjunction with gif decoder it implements support for reading animated gifs. Demuxer has two options available to user: default_delay and min_delay. These options are for protection from too rapid gif animations. In practice it is standard approach to slow down rendering of this kind of gifs. If you try to play gif with delay between frames of one hundredth of second (100fps) using one of major web browsers, you get significantly slower playback, around 10 fps. This is because browser detects that delay value is less than some threshold (usually 2 hundredths of second) and reset it to default value (usually 10 hundredths of second, which corresponds to 10fps). Manipulating these options user can achieve the same effect during conversion to some video format. Otherwise user can set them to not protect from rapid animations at all. The other case when these options necessary is for gif images encoded according to gif87a standard since prior to gif89a there was no delay information included in file. Bump lavf minor version.

* This fixes error handling for BeOS, removing the need for some ifdefs.François Revol2007-02-13
| | | | | | | | | AVERROR_ defines are moved to avcodec.h as they are needed in there as well. Feel free to move that to avutil/common.h. Bumped up avcodec/format version numbers as though it's binary compatible we will want to rebuild apps as error values changed. Please from now on use return AVERROR(EFOO) instead of the ugly return -EFOO in your code. This also removes the need for berrno.h.
