When we trying to use getMetadata() (Jetson Linux API Reference: NvVideoEncoder Class Reference), H.264 can retrieve metadata properly, but when I switch to VP9, every metadata shows 0.
Is there any way to retrieve the proper metadata from VP9 ?
This question connect to the API: setVirtualBufferSize (Jetson Linux API Reference: NvVideoEncoder Class Reference), it looks encoding bitrate are not controlled as CBR in VP9.
Here’s our test:
- Rate Control: CBR
- Preset: Slow
- Virtual Buffer Size:400kb
VP9. This looks working not proper.
