| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | libhevcenc: fix bitrate overshoot when lookahead is disabledRam Mohan2020-09-182-10/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

This change does not have any effect on the end bitstream but is expected to give performance gains on devices with low instruction cache.
