Video Encoding capabilities of iMX8M

msingh1920 — Sun, 05 Sep 2021 13:26:32 GMT

Hi Sir,

We are planning to use iMX8 M Quad and iMX8 M Plus for our product but have few questions regarding its video capabilities -

1. What are the maximum video encoding capabilities of the iMX8M quad and plus?

2. Is it possible to encode 4k60 with a hardware encoder or with any software encoder ?

3. Can we use vpu for 4k60 Encoder? what is the maximum limit of VPU for Encoding

4. Can we use vpu for 4k60 Decoder? what is the maximum limit of VPU for Decoding

Thanks,
Maneesh

Hi Maneesh

vpu capabilies can be found on below link

>2. Is it possible to encode 4k60 with a hardware encoder or with any software encoder ?

only with software encoder.

Hi @igorpadykov

Thanks for your reply.

It cleared some of my doubts. But still, I have few doubts please help me to solve that.

1. Is iMX8M Plus havs VCU800e VPU ?

2. can it do jpeg 4k60 encoding?

3. I am planning to use iMX8m Plus Board for SW Encoding at 4K 60fps and planning to try JPEG and technique. so is there any way I can utilize the VPU of iMX8m plus or it's not possible?

2. Is there any steps or doc or anything is available for 4k60 encoding on imx8m plus ?

3. do you have any idea what compression ratio we can achieve on iMX8m plus for JPEG encoding?

Any suggestion or reply will be very helpful.

Thanks,
Maneesh

Hi Sir @igorpadykov ,

Thanks a lot for your response.

Please suggest how can I achieve 4k60 encoding with an iMX8 processor?

Are there any reference documents or anything you can provide so that I can try to do 4k60 encoding?

Also, on Hantro website => https://www.verisilicon.com/en/IPPortfolio/HantroVC8000E
it is mentioned that =>
Hantro VC8000E allows 4K encoding with a minimal silicon single-core solution that supports HEVC and H.264 video formats. HEVC / H264 multi-core solutions can also be used, which can reach 8K@30fps (dual-core).

so why it is not supported on the iMX8 processor? because iMX uses the same VPU.

Thanks,
Maneesh
