encoder: Update chroma modules to avoid reading an extra byte

2021-03-27T04:30:56+00:00

When processing V plane, an extra byte was being read in some
of the neon modules.
Modules are now updated to avoid that extra byte read.

encoder: Do not use memcmp for volatile data

2021-01-15T20:39:41+00:00

memcmp was used in a loop to compare data that
was being updated by other threads.
memcmp doesn't support comparing volatile data.

This is now replaced by a function which
compares the volatile data to zero

libhevcenc: fix bitrate overshoot when lookahead is disabled

2020-09-18T12:26:53+00:00

When rc lookahead is disabled, next frame encode context becomes NULL.
This context is used to signal end of gop. As this is NULL rc does not
know the end of gop causing over consumption of bits. Rely on intraframe
interval to resolve this.

Also, as there is no scene change detection, default all pics to single scene.

libhevcenc: Release async control command buffer

2020-06-04T22:58:51+00:00

Async command control buffer is not being released after use.
This is corrected.
Also ensured dynamic bitrate doesn't go below min supported bitrate
