Hi
I'm attempting to determine maximum bit rate using HW encoder HEVC and XAVC.
Reading the code :
it seems that maximum bit rate for AVC is 360Mbit/s so I can't create XAVC class 300 @60P (bit rate of 600Mbit/s). Correct ?
I didn't find any similar function for HEVC. What's maximum bit rate obtainable using HW encoder?
I need to encode 4K@60 (3840x2160@60P); can I reach 600Mbit or more ?
regards

Hi,
Good day to you.
Thanks for posting in Intel Communities.
>> it seems that maximum bit rate for AVC is 360Mbit/s
Have you observed this while encoding any raw video?
Are you trying this with the latest version of the sample_encode present in the link: https://github.com/oneapi-src/oneVPL/tree/ca5bbbb057a6e84b103aca807612afb693ad046c/tools/legacy/sample_encode.
Reference to build oneVPL: https://github.com/oneapi-src/oneVPL/blob/master/INSTALL.md
Further more, we are checking with the development team and will let you know what are maximum bitrates possible for both H264(AVC) and H265(HEVC) codec and whether XAVC class 300 @60P with a bitrate of 600 Mbit/s is supported by oneVPL/MediaSDK.
Can you provide us with the following information in order to understand your query better:
1. Hardware/OS Versions
2. Are you using MediaSDK or oneVPL. The version of MediaSDK or oneVPL
3. Commands used for encoding along with a sample test video to replicate it from our side.
Regards,
Jyothis V James
