Adds fields lambda, lambda_sqrt and qp to encoder_state_t. Drops field
cur_lambda_cost_sqrt from encoder_state_config_frame_t and renames
cur_lambda_cost to lambda.
- Defines MIN_LAMBDA and MAX_LAMBDA constants.
- Moves resetting state->frame->cur_gop_bits_coded to rate_control.c.
- Changes gop_allocate_bits to return the number of bits allocated like
pic_allocate_bits does.
When --threads=auto was given on the command line, cfg->threads was
actually set to zero, disabling threads altogether. Fixed to set
cfg->threads to -1, so that the number of threads is chosen
automatically.
The CABAC engine only writes to the bitstream when it has a full byte.
These writes are also always byte-aligned, so there is no need to even
check for stream alignment.
Speedup was around 3% with ultrafast and low QP.
Enforce bit depth promised by --input-bitdepth to avoid crashes when
larger values are provided.
Do endianess byte swap for all bytes when the buffer gets extended
to multiple of 8 pixels, and not just the number of input pixels.
Don't swap bytes on a little-endian system.
- Reduce indentation to 6 spaces
- Word wrap everything to under 80 characters
- Remove defaults from options covered by presets
- Add a dash in front of argument descriptions
- Add --(no-) to names of parameters that accept it and remove mention
of enabling or disabling
- Add executable and scripts as a dependancy to make docs
This value is not represented in the HEVC bitstream, which is why it
was not set previously. FFmpeg sets and needs it however, so make the
CLI set it as well to make sure we handle it correctly.
Depending on the distro, the pkg-config package name of crypto++ could
be either cryptopp or libcrypto++. This commit changes configure to
check for both instead of cryptopp only.
The rd-complexity of slow presets is better with a less agressive GOP.
Adding the GOP as part of the preset improved BDRate enough, that it
didn't make sense anymore to have a veryslow target the best BDRate.
Instead, push that responsibility to placebo by making it a little bit
faster.
Now that WPP is on by default, Valgrind is finding memory leaks on
these tests. It's not a priority so I'll just disable it for now.

GOPs with depth 1 had the same structure as those with depth 2:
g4d3t1 = 3 2 3 1
g4d2t1 = 2 2 2 1
g4d1t1 = 2 2 2 1
It now results in the correct:
g4d1t1 = 1 1 1 1
