Hi, dear media team.
I have issue with latest release of the OneVPL.
I want to use SW library from the package with CBR mode but it doesn't work.
SW library is C:\Program Files (x86)\Intel\oneAPI\vpl\2022.2.0\bin\libvplswref64.dll
CL: sample_encode.exe h265 -cbr -i D:\Streams\in.yuv -o D:\Streams\out.h265 -w 1920 -h 1080 -b 1500 -r 1 -f 30 -timeout 20 -sw
The same issue for AVC.
CPU
11th Gen Intel(R) Core(TM) i7-11370H @ 3.30GHz
Driver 27.20.100.9664

Hi,
We were able to reproduce your issue with the command you've run. Please try running your command prompt as an administrator & try with hardware implementation as below:
sample_encode.exe h264 -cbr -i input.yuv -o output.h264 -w 1920 -h 1080

Hi Roman,
We got an update from the Dev team that oneVPL Software implementation is a reference implementation. So, we don't expect it to support CBR for all codecs. One known limitation is, encoders with CBR rate control, big resolution, and small max bitrate may fail.
Here is a Media SDK article that discusses the impact of different metrics for CBR/VBR:
If this resolves your issue, make sure to accept this as a solution. This helps others with similar issue. Thanks!

Alekhya

Hi,
We assume that your issue is resolved. If you need any further assistance, please post a new question as this thread will no longer be monitored by Intel.
