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.

There is no hardware decoder for i.MX93. 

The SW decoder can be enabled in the build by making the following changes to the  conf/local.conf file:

LICENSE_FLAGS_ACCEPTED += "commercial"
IMAGE_INSTALL:append = "gstreamer1.0-libav"
PACKAGECONFIG:append_pn-gstreamer1.0-libav = "x264"

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.
