External segmentation maps not working (VP8E_SET_ROI_MAP) #411

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago
As reported here[1], the ROI map feature is currently broken.

* The user's segmentation map is not used on the initial keyframe
* Segmentation is enabled on subsequent frames, but the map data update isn't, 
so the decoder never gets a copy of the map the encoder is using.

There is a fix to this bug pending review.

However I also note that the documentation appears to be incorrect.
I believe that the valid range of input values for both delta_q and delta_lf
is [-63 to +63] not [-64 to +64] and [-32 to +32] as described in
http://www.webmproject.org/tools/vp8-sdk/structvpx__roi__map.html#_details
