iMx6 ,adv7180 and gstreamer

inkwaterman — Wed, 24 Jul 2013 08:29:59 GMT

Hi !

I have to use a iMx6 with adv7180 under linux (i started with ltib L3.0.35_4.0.0_130424).

I tested my hardware with the mxc_v4lv_tvin.out unit test , with the following command line:

./mxc_v4l2_tvin.out -ow 640 -oh 480 -ol 10 -ot 20 -f YU12

and it works well...

But if I use it with gstreamer , the image start to rolling...

My command line is:

gst-launch-0.10 -v mfw_v4lsrc ! mfw_isink

I found a topic about iMx53 and adv7180. In this topic they suggest to use the command:

gst-launch-0.10 -v mfw_v4lsrc capture-width=720 capture-height=576 sensor-width=720 sensor-height=288 typefind=1 preview=1 preview-width=720 preview-height=576 bg=1 ! mfw_isink

but my mfw_v4lsrc not support the capture-width, capture-height, sensor-width and sensor-height....

Where I'm wrong ?

Thanks

What do you mean by 'rolling'? add --gst-debug=*mfw*:5 to your pipeline and share log.

This is the log of gst-launch-0.10 -v mfw_v4lsrc --gst-debug=*mfw*:5 ! mfw_isink command:

Hi,

Please copy libmfw_gst_tvsrc.so to your rootfs/usr/lib/gstreamer-0.10 directory, and take gstreamer pipeline “gst-launch tvsrc ! mfw_v4lsink”

It works...

Wonderful !...

Hi !

I have tried to capture a live view of my adv7180 with this pipeline:

gst-launch tvsrc ! vpuenc ! matroskamux ! filesink location=./test2avi

The file test2.avi was created (it seems correctly), but vlc and gstreamer are unable to show the recording data.

The pipeline below instead works...

gst-launch videotestsrc ! vpuenc ! matroskamux ! filesink location=./test.avi

where I'm wrong ?

timharvey — Mon, 12 Aug 2013 17:24:40 GMT

Where is the source for libmfw_gst_tvsrc and gstreamer-fsl in general? Does Freescale develop this privately and only release periodic source within the IMX_MMCODEC packages? Is there a release timeline?

Re: iMx6 ,adv7180 and gstreamer

s_bai — Mon, 04 Nov 2013 15:48:50 GMT

I actually have the same doubt. My ADV7180 works perfectly with tvsrc but not with mfw_v4lsrc, I tried to directly invoke the V4L2 API followed exactly same sequence from strace of tvsrc but still getting rolling images. What's more strange is that if I run tvsrc once and stop touching any setting of the capture interface, my capture will work greatly. I guess there is something wrong with my VIDIOC_S_FMT call but I couldn't find what exactly is wrong. Does someone have similar problem as us? And how did you solve it?
