The options are now:
-duration d -> set the whole animation to duration 'd'
-duration d,s -> set only frame 's' to duration 'd'
-duration d,s,e -> set only interval [s,d] to duration 'd'
+ style fix
Change-Id: I72e95282d520146f76696666f44280ad9506affa
this will force a constant duration for an interval of frames
in an animation.
Notes:
a) '-duration [...]' can be repeated as many times as needed.
b) intervals are taken into account in option order. If they overlap, values will be overwritten.
c) 'start' and 'end' can be omitted, but not the duration value.
d) 'end' can be equal to '0', in which case it means 'last frame'
e) single-image files are untouched (ie. not turned into an animation file).
Some example usage:
webpmux -duration 150 in.webp -o out.webp
webpmux -duration 33,10,0 in.webp -o out.webp
webpmux -duration 200,2 -duration 150,0,50 in.webp -o out.webp
Change-Id: I9b595dafa77f9221bacd080be7858b1457f54636
Also use a naming 'extended format' rather than 'container file' to be
consistent with the container specification.
Change-Id: I3b07f95e0244d3534fe17b03f60db22f61e17836
- Allow a duration of 0
- Rename LOOP chunk to ANIM and add the background color field to it.
- Add a disposal method field for each animation frame.
- Modify webpmux.c binary interface to allow the input of background color
and disposal methods. Also make '-loop' and '-bgcolor' arguments optional
with some default values.
Change-Id: I807372a61cdb8a0d3080ae3552caf2848070bf4d
- Also, use the term 'fragments' instead of 'tiling' in code
- This makes code consistent with the spec.
Change-Id: Ibeccffc35db23bbedb88cc5e18e29e51621931f8
Use separate fourCCs "XMP " and "EXIF" instead of a common "META"
Also, some refactorization in webpmux.c
Change-Id: Iad3337e5c1b81e785c60670ce28b1f536dd7ee31
'Set' and 'Get' methods for images take/return a bitstream as input,
instead of separate 'image' and 'alpha' arguments.
Also,
- Make WebPDataCopy() a public API
- Use WebPData for storing data in WebPChunk.
- Fix a potential memleak.
Change-Id: I4bf5ee6b39971384cb124b5b43921c27e9aabf3e
- send errors to stderr
- send help to stdout
- add image size to webpmux -info output and send to stdout
- correct webpmux exit values
Change-Id: Ifd8e8493aab33a82765f7b7903cef345d96da9ae
- Add alpha support in mux.
- Remove WebPMuxAddNamedData() and WebPMuxGetNamedData() APIs. Add WebPMuxSetImage(), WebPmuxGetImage() and WebPMuxDeleteImage() APIs instead.
- Refactor code using WebPImage struct.
- Corresponding changes in webpmux binary.
- WebPMuxSetImage()/AddFrame()/AddTile() can now work with data which starts from "RIFF...". This simplifies reading a single-image webp file and adding it as an image/frame/tile in mux.
Change-Id: I7d98a6407dfe55c84a682ef7e46bc622f5a6f8d9
Added the Mux Container Spec (RIFF structure) for the features supported
(Color Profile, XMP Metadata, Animation & Tiling) via WebP Mux. Also
added README file with example psudo code for using the Mux API(s) and a
short description on webpmux (comand line tool, planned to be pushed out
in subsequent Git change).
