Buffer allocation for substream with wpp

Description

Hi,

I've got an error with this stream on HM10.0 . Disclaimer: This stream has been made by me so it can't be considered as bugfree.

However, it looks like HM encounters an assert on this stream at the end of first wavefront. This assert is a check on fifo size to ensure hm still have an allocated buffer wile reading on it. It looks like the buffer size just has 1 byte missing (264 rather than 265).

What do you think of this ? Do you confirm me it is an HM bug ?

Thanks and Regards,

Ignoring the very broken profile signalling in the SPS,

Are you counting emulation prevention bytes in your substream offsets?

There is an emulation prevention byte in the first substream that decreases the size from 265 (as signalled) to 264.

  • Milestone changed from HM-10.1 to HM-11.0

Fixed in r3475
Could be a nice conformance stream if it weren't for all the issues in VPS/SPS
