Hello There !
We are looking at using the iMX8M for a video decoder product, see attached. Essentially its taking in MPEG2 TS, decoding it and showing it in the GUI (LCD), TV/HDMI while re-encoding / transcoding the video to H.265. I need the decoder to be running all the time, then have the other components run and stop as needed.
Ideally we want to support 4K60 on the HDMI output, while GUI & Transcoding would be (downscaled to) 1080P60
Firstly I'm looking to find out if this is even possible / plausible. Secondly I'd appreciate some advice on which gstreamer components to use and what documentation to read up on
Thanks in advance,
/Otto
Thanks Igor !
4K30 on the HDMI is acceptable.
Using "tee" on raw video works ? I would that's quite difficult to support with the DMA involved etc
yes tee is supported.
Best regards

Hi Otto
in general such decoding and transcoding is possible, as for HDMI it is limited to
3840x2160p30 as described in sect.1.4.2.12 Display Interfaces
i.MX 8M Plus Applications Processor Reference Manual
>some advice on which gstreamer components to use and what documentation to read up on
one can look at Chapter 7 Multimedia i.MX Linux User’s Guide
