Hello,

Now I'm trying the realtime converting video format from MPEG2 to H.264.
But the i.MX8M doesn't have more performance to convert at realtime.
I don't know another way so,
If you know, would you like to let me know something cases about this?

my environment is below.
CPU: i.MX8M
RAM: 4GB
OS: Android 11

Best regards,

do you need encoder or decoder? do you use imx8mq?

Yes, I use imx8mq.

What I want to do is encoding MPEG2 to H.264.
That means a source is MPEG2, and I want to get a video converted to H.264.
If it is occured something decoding in that process, It doesn't matter.

normally vpu(HW) can do this job, but imx8mq vpu doesn't support encoder, so you only can do this by SW(CPU)
