Uninitialize() is most likely to be removed. Hence

+ // Decode one JPEG image from shared memory |input_buffer_handle| with size |
+ // |input_buffer_size|. The input buffer is associated with |input_buffer_id| |
+ // and the size of JPEG image is |coded_size|. Decoded I420 frame data will |
+ // be put onto shared memory associated with |output_video_frame_handle| |
+ // with size limit |output_buffer_size|. |
+ Decode(JpegDecodeInfo info); |
+ |
+ // TODO(c.padhi): This method might not be required, see |
+ // http://crbug.com/699255. |
+ // Destroy request to the decoder. |
+ Uninitialize(); |
