SK-AM62A-LP: MJPEG encoding capability

Part Number: SK-AM62A-LP

Hello Team,

Which video resolutions are supported by MJPEG hardware encoder on AM62A34? Can we use below resolution for encoding?

1. 1080p@30

2. 480p@60

3. 1080p@30 and 480p@30 simultaneously. (This is supported on H264/H265 hardware encoder but data is not available for MJPEG encoder)

Please point me if any data available regarding resolution supported on MJPEG hardware encoder?

Thanks,

Hi Jaimin,

I just tried this on my AM62A board and was able to encode two streams simultaneously.

gst-launch-1.0 -v \
videotestsrc num-buffers=100 ! video/x-raw, width=640, height=480, format=NV12, framerate=60/1 ! v4l2jpegenc ! filesink location=op480.jpeg \
videotestsrc pattern=ball num-buffers=100 ! video/x-raw, width=1920, height=1080, format=NV12, framerate=30/1 ! v4l2jpegenc ! filesink location=op1080.jpeg

Best Regards,

Suren

Thank you Suren for providing above information.

Could you please provide the maximum resolution of 2 streams which can be encoded simultaneously in JPEG hardware encoder? I am not able to get this information from datasheet. Let me know if any data available on this.

Hi Jaimin,

According to the features supported on E5010

This information can be found in the SDK documentation as well as the TRM

https://software-dl.ti.com/processor-sdk-linux/esd/AM62AX/09_02_00/exports/docs/linux/Foundational_Components/Kernel/Kernel_Drivers/E5010_JPEG_Encoder.html

Hope this helps

Hi Suren,

I mean to resolution along with fps. As per above data resolution is mentioned as 8kx8k but what maximum FPS which can achieve with this resolution using JPEG encoder?

Does it support 2 streams of 1080p@30 FPS? Is there any calculation available how many pixels can be encoded within a second?

Thanks,

Hi Jaimin,

Yes you should be able to do 2 1080p@30FPS as we support 4k resolutions at 30fps for sure.
Also the data sheet says clearly this:

Hope this helps.
