Description

There are issues related to HRD signalling with VTM-9.0 when encoding a bitstream containing HRD parameters and BP/PT SEI messages:

  1. Bitrate and CPB size are always set to 0 in the HRD parameters: this bug is due to pointer issues when copying the value of the HRD parameters to the SPS syntax
  2. Picture timing SEI message is missing for some pictures: this bug is due to the PT SEI message not being created at all for some pictures, because the function xCreatePictureTimingSEI checks the value of the nuh_layer_id within the slice which is never set beforehand

These bugs can be generated using the following command line:
./EncoderAppStatic -c ../cfg/encoder_randomaccess_vtm.cfg -c ../cfg/sei_vui/timing.cfg -c ../cfg/per-sequence/BlowingBubbles.cfg -f 17
