Hi,
I'm monitoring the Buffers timestamp before and after vpu decoder. In the case of single stream the timestmap looks fine. Output buffer from VPU has the same TS of the input buffer.
When decoding multiple streams the VPU output buffer has a strange TS value for some streams while the correct value for others!
I have enabled VPU and ME debugging and here are the logs:
Good case:

What is cause the TS corruption and is there a proposed solution?
Hi
Are you using gstreamer for the multiple decoding? If so, can you share the pipeline used.
Also can you share how to enable the VPU and ME debugging, so I can try to reproduce the problem, please?
Thanks
