#818 closed defect (duplicate)

Multiple SPS with same ID

Reported by: fuldseth Owned by:
Priority: minor Milestone: HM-9.1
Component: HM Version: HM-8.1
Keywords: Cc: fbossen, ksuehring, davidf, jct-vc@…


Assuming that multiple SPS with the same ID are allowed by the standard, the HM decoder does not seem to work properly.

Problem description:

HM allocates a buffer containing new SPS each time it received new SPS. With the second SPS with same ID, it frees previous SPS buffer.
However, previously decoded slice is not yet output and still has its SPS buffer pointer referring to freed buffer. When this decoded slice is output (after reading slice header of next IDR), it uses corrupted SPS parameters from freed buffer then crashes.

Could you please check if issue #835 is a duplicate of this? A patch for that has been applied in HM-9.0-dev.

Yes, the patch for issue #835 should also fix this issue.
