- Note we did test this briefly on the SDK 11.1 release, and the videocrop wasn't needed. Though I didn't dig into the driver to see what they might have fixed.

- Holden,
No problem; glad to hear things are working now on your end!

- Hi Jake,
Thank you for looking into all this, it has been extremely helpful!
I looked into how the app actually talks to X11 and found a potential way to keep the app alive while the xserver is stopped so I can utilize kmssink. Pre...

- Good morning Holden,
No worries and thanks! I have tried out your X11 image with the pipelines discussed above and things are similar on my end as well. I have tried various pipelines to see what one offers ideal performance and low u...

- Hi Jake,
I apologize I had not seen your previous post (and also brainfarted and thought you were referring to testing on X11 initially) before sending my update. Killing the weston and using the kmssink pipeline you provided, the vid... - JP 05:18 PM Software Development: RE: Playing MP4 to Display Troubles
- Holden,
Disregarding X11 & ximagesink for now, can you just initially try our pipeline(s) to see if this is working on your setup?
Also, if you could send the SD card image you are using or tell us how to build it with your X11 mod... - HW 04:18 PM Software Development: RE: Playing MP4 to Display Troubles
- I tried with the pipeline you tested with ximagesink and it still seems pretty laggy. On X11, I get linking failures using videocrop; as far as I have seen it only works when using videoconvert between the decoder and the sink but there...

- Good afternoon Holden,
I also have gotten kmssink to work with the following pipeline:
$ gst-launch-1.0 filesrc location=bunny.mp4 ! qtdemux ! h264parse ! v4l2h264dec ! videocrop left=2 ! kmssink
This is very similar to the prev...

- Hello Holden,
I have been looking into your issue with @jcormier, and we are able to get the video to playback at 30fps with around ~40% CPU utilization and no visible signs of frame loss or lag using the following pipeline:
$ gst-...

- Hi Jake and Mike,
We do not need Weston/Wayland specifically, but we have a legacy app that heavily depends on X11 which might cause some difficulty using drm/kms. The same issue is present using X11 (using ximagesink instead of wayla... - MW 07:13 PM Software Development: RE: Playing MP4 to Display Troubles
- Hi Jake and Holden,
I think the issue may be related to using weston/wayland instead of drm/kms.
The AM62Ax does not have a GPU, so weston/wayland rendering is going to be
CPU bound.
Do you need weston/wayland?

- Good afternoon Holden,
I am looking into your issue now and have replicated some of your failing behavior. I will update you when I have further info/findings.
Thank you,
Jake - I have been trying to output MP4 video to the display using the hardware encoder/decoder. For the sake of consistency, I am using the 10.01 SDK prebuilt tisdk-default-image and making changes in ti-linux-6.6.y. This image provides the gs...
