Is it possible to play an MP4 format video on screen with i.MX93EVK?

[killedByBugs]

My i.MX93 EVK is connected to a screen. It successfully shows the Weston desktop. Then, it failed and gave out an error when I tried playing an MP4 format video using the following GStreamer command

gst-launch-1.0 filesrc location=myBuggy.mp4 ! decodebin ! autovideoconvert ! autovideosink

The error message was:

Is there any possible way to play an MP4 video on screen with i.MX93EVK?

Thank you in advance.

Hi @killedByBugs, 

Thank you for contacting NXP Support.

You can try with the following command:

gplay-1.0 your-video.mp4

Please try and tell if it works.

Have a great day!

Hi Brian,

I have tried the following command you mentioned previously:

gplay-1.0 my-video.mp4

It doesn't work. There is no video shown on the Wayland desktop. The output information on the terminal:

playbin3 is enabled

However, It can play test videos of GStreamer by using the following command:

gst-launch-1.0 -v videotestsrc pattern=snow ! video/x-raw,width=1280,height=720 ! autovideosink

It seems it can't play any MP4 format video because it has no decoder like H.264. Is there any solution to this problem?

 Thank you.
