usb camera streaming to the screen on i.MX8 with vpudec

[mckim]

Hello,

About usb camera streaming to the screen on i.MX8,

the below command works, but framerate is too slow,

gst-launch-1.0 v4l2src -v device=/dev/video2 ! image/jpeg,width=1920,height=1080,framerate=30/1 ! jpegdec ! autovideosink

so If I use the below command for using hardware decoding,

gst-launch-1.0 v4l2src -v device=/dev/video2 ! image/jpeg,width=1920,height=1080,framerate=30/1 ! vpudec ! autovideosink

it show "OMX JPEG ! decoder_decode_jpeg JPEGDEC_STRM_ERROR", vpudec does not work.

Could you solve this problem?

I tested it with v5.10_1.0.0, L5.4.70, L4.19.35 image, it still did not work.

But i.MX6 works ok with v5.10_1.0.0, is there any other parameter do I have to use to run it on i.MX8?

Thank you...

Hi Min

i.MX6 and i.MX8 use different plugins as described in Table 15. i.MX GStreamer 1.0 plugins

i.MX Linux Release Notes

examples can be found in  i.MX8GStreamerUserGuide.pdf

Hello, igorpadykov,

Thank you for the reply.
I have checked the document.
vpudec should work both on i.MX6 and i.MX8.
I think it does not need any different command, pipeline, or plugin to play usb camera beween i.MX6 and i.MX8.
Could you check it again?

Thank you...
