imx6S problem with webcam (GStreamer)

Archimede — Sun, 08 Nov 2015 18:03:06 GMT

Hi,

this is my first post so I hope to respect any rules..

I'm developing a board based on IMX6S and I have some issue with gstreamer and the webcam (microsoft life cam cinema).

The board (I have the same problem with the wand board and with the soloLite Freescale demo bard) is connected to a 800x480 display,

I have yocto jethro and the last gstreamer, when I use this pipeline:

gst-launch-1.0 --gst-debug=*:3 v4l2src device=/dev/video0 do-timestamp=true ! 'image/jpeg,width=1280,height=720,framerate=10/1' ! imxvpudec ! imxipuvideotransform ! imxipuvideosink sync=false

sometimes it work correctly, sometimes it works at very low frame rate with this Warning:

0:00:13.753400668 410 0xf3aa00 WARN videodecoder gstvideodecoder.

c:2512:gst_video_decoder_prepare_finish_frame:<imxvpudec0> decreasing timestamp

(0:00:00.000000000 < 0:00:12.450436303)

and sometimes it show me just the first frame.

I can't find a way to replicate the problem in a constant way (and this is frustrating). Another warning I see sometimes is:

0:00:10.566781001 667 0x16b0720 FIXME v4l2 gstv4l2bufferpoo

l.c:1152:gst_v4l2_buffer_pool_dqbuf:<v4l2src0:pool:src> Unhandled enum v4l2_fiel

d 0 - treating as progressive

In the attache file the log when I obtain just the first frame.

any idea or suggestion?

Thanks for any help!

Hello,

perhaps the problem concerns with performance issue. You may try the recent

Have a great day,
Yuri
