Arttu Ylä-Outinen 1d2a398197 Move function kvz_encoder_feed_frame to a separate module.
Adds module input_frame_buffer.

Arttu Ylä-Outinen 70b3e10e27 Fix a crash with owf=4, gop=8, frames=10.
A call to kvz_threadqueue_waitfor caused the tqj_bitstream_written field
of the previous encoder state to become a dangling pointer, subsequently
causing an assertion to fail. This would only occur when the encoder
state used for a new frame was not the last finished one.

Fixed by setting tqj_bitstream_written to NULL after the job is done and
removing unnecessary calls to kvz_threadqueue_waitfor.

- Renames struct bitstream_chunk_t to kvz_data_chunk.
- Renames macro BITSTREAM_MEMORY_CHUNK_SIZE to KVZ_DATA_CHUNK_SIZE.
- Removes kvz_payload typedef.
- Adds function chunk_free(kvz_data_chunk *chunk) to kvazaar API.

Arttu Ylä-Outinen cecdf4f34e Move config validation to encoder_control_init.
Ensures that config is valid even when not initialized by config_read.

Arttu Ylä-Outinen 398f0c823b Replace memory bitstreams with linked lists.
- Removes all bitstream types.
- Changes encoder_encode to return the encoded data as list of chunks.
- Moves writing of the encoded data to the main function.
2015-07-02 16:35:46 +03:00
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 1f41717351 Rename stats_done to frame_done in encoderstate.
The new field frame_done is set to zero when starting to encode a new
frame and reset to one when the encoded data has been written.

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.

Arttu Ylä-Outinen f41ce04488 Refactor main function.
- Make sure that everything which is allocated gets deallocated.
- Move finalization of encoder states to kvazaar.c.
- Remove empty strategyselector_free function.
- Remove unused variable curpos.
- Fix includes.

Arttu Ylä-Outinen 4a7b86a43b Make g_exp_table statically allocated.
Removes the need to free the table.
2015-07-02 16:14:52 +03:00
Arttu Ylä-Outinen b130ecc9bb Fix "reference not found" when GOP is enabled.
The encoder state must be cleared by calling encoder_next_frame before
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 df50a0dae6 Move config_parse into api. 2015-07-02 15:52:24 +03:00
Ari Koivula 4e5326d3d5 Move encoding to API.
- Api->encoder_encode can now be called repeatedly to start encoder
  jobs and to retrieve the results.
