f7f16a2976 add ABI compatibility check
minor revision shouldn't matter, we only check major revision number.
Bumped all version numbers so that incompatibility starts *now*

05108f6ea0 Merge "More spec/code matching in mux:" 2012-07-12 23:53:58 -07:00
Urvang Joshi
6808e69db8 More spec/code matching in mux:
- Match offsets, duration, width/height for frames/tiles and enforce
some constraints.
- Note that this also means using 'int's instead of 'uint32_t's for
16-bit and 24-bit fields.

c0e8859d81 Get rid of image_info_ from WebPChunk struct.
The image_info_ was used only in GetImageCanvasWidthHeight(). So, now
we infer it from data there.
This removal fixes a bug: earlier, 'image_info' wasn't initialized in
the WebPMuxCreate() flow, and so the canvas width/height were being
calculated to be zero.

Also, a related refactoring: Combine CreateImageInfo() and
CreateDataFromImageInfo() into a single function CreateFrameTileData().

b74ed6e766 Mux API change:
'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.

c975c44ea5 Alpha flag fix for lossless.
- Make sure alpha flag is set in case of a lossless file with VP8X chunk.
  The semantic of ALPHA_FLAG changes with this: it means the images
  contain alpha (rather than ALPH chunk in particular).
- Update the mux container spec to add 1-line description of alpha
  flag.
- Rename "HasLosslessImages()" to "MuxHasLosslessImages()", and other
  similar function renames.
- Rename FeatureFlags to WebPFeatureFlags
- Elaborated a comment for a special case.
- A misc comment fix.

8d77dc29e1 Add support for lossless in mux:
- Separate out 'CHUNK_INDEX' from 'TAG_ID' (this is to help with the
  situation where two different tags - "VP8 " and "VP8L" can have the
  same TAG_ID -> IMAGE_ID).
- Some internal methods now take 'CHUNK_INDEX' param instea of 'TAG_ID'
  as appropriate.
- Add kChunks[] entry for lossless.
- Rename WebPMuxImage.vp8_ --> WebPMuxImage.img_
- SetImage() and AddFrame/Tile() infer whether the bitstream is a
  lossless one based on LOSSLESS_MAGIC_BYTE. The correct tag is stored
  based on this.

Also, handle the case when GetVP8Info/GetVP8LInfo() fails.
