The commit be197cf5 has caused the corrupted decoded video frames with speed=0 or 1, since its landing on June 26. The quick fix is to disable skip RDO loop, removing its outermost loop, and set skip = false. This bug has been there around a month and believed to be the culprit of breakage of ext_partition_types PR by TD-Linux as well. Better fix will come, which is also coincidentally stated earlier in https://github.com/xiph/rav1e/issues/373.

No need to clutter up lib.rs with self-contained CDEF work. Split the CDEF functions into their own file. No functional change.

* Define reference frame buffer array A reference frame buffer with 8 slots is defined. The buffer is updated after encoding each frame according to the value of refresh_frame_flags. The value of refresh_frame_flags is also set and properly encoded. * Fix test function Also move update of frame buffer to a separate function * Use named constants instead of magic numbers

* Remove 'EXT_' in'EXT_TX' for the names Since everything that has been called extended is now a standard. * Rename TxSetType TxSet and etc - Rename 'ext_tx_' as 'tx_'. - Rename 'write_tx_type_lv_map' as 'write_tx_type'. * Rename '*_set_type' as '*_set' * Rename '*_ext_tx' as '*_tx' Because it is not 'extended' anymore but a standard.

* Make more structures Debug Makes easier to println!-debug. * Fix the cmake flags passed to build the decoding library * Make sure to not call partially implemented ith At least the sse4.1 variant is incomplete and triggers an assert. * Do not use SIMD for TxType::IDTX ith The implementation of it is incomplete. * Provide an encode-decode test Use `cargo test --features=decode_test -- --ignored` to run it. * Enable decode_test in travis

* cdef: WIP * cdef: now calling cdef_find_dir_c (but only on the first block) * cdef: call cdef_find_dir on every block (only safe for size % 64 == 0) * cdef: apply CDEF to luma with pri_strength 7 and sec_strength 0. * cdef: only apply to full 64X64 filter blocks for now * cdef: signal cdef strength * cdef: comment out printing * cdef: first attempt at applying CDEF to chroma planes * Corrections to first CDEF attempts This is still not quite first cuts, but it is basically functional. It still hard-codes specific CDEF strengths. There is still an occasional block mismatch. * Implement CDEF paramters, remove hardwired settings Add CDEF settings to the FrameInvariants, rather than using hardwires strength values duplicated in multiple locations. * Remove last CDEF dependency on libaom * Remove unrelated change from CDEF work remove -r rec_file.y4m from rav1e command line

It turns out that there's already some code to emit the skip_mode_present flag, it's just dead code because skip_mode_allowed is currently always false, added an assertion to revisit this code when it becomes live because it's incomplete.

Which includes both tile group header and tile data.

TODO: Need to fix writing the size of OBU_FRMAE payload in obu header, which is the sum of obu_tile_gropu and a tile.
-
So that it can be used for both show_existing case and tile (group) case. TODO: Add write_tile_group_header() for each tile group.

Both OBU_FRAME or OBU_FRAME_HEADER obu types call this function.

Write the length of OBU payload between a OBU header and a OBU payload, which introduces two byte buffers and BitWriters at the same time. TODO: - Do similar thing for Frame OBU - Can better factor out the code which does post-writing of the length of OBU payload data. - Multi buffer approach, that is rust dependent, can be improved.

The uleb size is the size of length field in bytes. https://aomediacodec.github.io/av1-spec/#leb128 TODO: - Include uncounted sequence syntax data to seqence payload size. - Implement uleb128()
