Hi All,

After Freescale was so kind and forward the v4l-codadx6-imx27.bin the firmware loaded properly and I see a /dev/video1 the v4l_ctrl looks promising

root@gtsir-nand:~# v4l2-ctl --list-formats -d /dev/video1
ioctl: VIDIOC_ENUM_FMT
        Index       : 0
        Type        : Video Capture
        Pixel Format: 'H264'
        Name        : H264 Encoded Stream

Index : 1
Type : Video Capture
Pixel Format: 'MPG4'
Name : MPEG4 Encoded Stream

root@gtsir-nand:~# v4l2-ctl -d /dev/video1 -l

But the capture is not working :-(

root@gtsir-nand:~# ./video1.x -f MPG4  -w 320 -h 240 a.mpg4
g_width = 320, g_height = 240
--------------------------------------------------------------------------------------------
	 Width = 320	 Height = 240	 Image size = 589824
	 pixelformat = 875967048	 colorspace = 3
--------------------------------------------------------------------------------------------
^C

and the kernel spit this

[ 3043.981600] coda coda-imx27.0: coda_stop_streaming: timeout, sending SEQ_END anyway
[ 3044.998085] coda coda-imx27.0: CODA_COMMAND_SEQ_END failed

did I miss something ?? just enlighten me please

Thanks
Chris
