Arttu Ylä-Outinen 7e20e62cc7 Make kvazaar_encode consume one frame on each call.
- Replaces read_one_frame by encoder_feed_frame.
- Adds field "prepared" to encoderstate_t to indicate that
  encoder_next_frame has been called.
- Input frames are read in the main function and passed to
  encoder_encode.

Arttu Ylä-Outinen 50a5d5faa5 Let subimages have multiple references.
Adds function image_copy_ref to image module for getting a new reference
to an image. It can be used instead of image_make_subimage when the
sizes of the original and the subimage are same.

calling read_one_frame.

Ari Koivula 7e98a483d7 Use the API for checking whether the encoding is finished. 2015-07-02 16:14:51 +03:00
Ari Koivula fc58748ae8 Output bitstream through API.
- Use the existing bitstream_t type to give access to the bitstream.
  We can extend it later to make it a linked list like I was planning
  to do with the payload type.
- The main encoder now also stores the bitstream in memory.

Ari Koivula 9a3edce3fc Separate input and output from encoding.
- Move image_t and pixel_t to the kvazaar.h API.

Ari Koivula f87cea78da Wait for bitstream immediately after encoding the frame.

  real time.

Ari Koivula ad11d1bca5 Add kvazaar.h to hold high-level encoder API.

- OWF stuff is made more explicit by counting the frames instead of
  communicating through encoder_state_t.stats_done.
2015-07-02 15:45:33 +03:00

2015-05-29 11:50:08 +03:00
Arttu Ylä-Outinen b24d92bd6e Move initialization of constants to encoder.c.
