Missing initialization of I_PCM transform index

Reported by: kchono Owned by:
Priority: minor Milestone: HM-6.2
Component: HM Version: HM-6.1
Keywords: Cc: fbossen, ksuehring, davidf, jct-vc@…


When I_PCM is selected, its transform index is not initialized at decoder. Although tranform index is not used in I_PCM encoding and decoding, the value should be initialized (with 0). Attachment is a patch to HM-6.1-dev rev.2173. (Note that the patch also includes the initialization at encoder to ensure it in future modifications in the related codes.)

The patch does not affect results under common test conditions with I_PCM as long as QPs of I_PCM regions are set to 0 during deblocking process.
