Hi,
I'm working on an iMX6 project that inputs HDTV via USB or mini PCIe TV tuner card. The first TV tuner I got is Hauppauge 950Q. I followed the instruction from our Freescale FAE.
==
The instructions on how he enabled the device are below for your reference but wanted to share a couple other comments…
Here are the implementation details.
I had to enable 3 drivers: Xceive XC5000, Auvitek AU8522, Auvitek AU0828.
I used a barebones Linux: no need for a full Ubuntu distribution.
Here are the steps:
1) Build latest LTIB Linux BSP (L3.0.35_4.1.0) with all of gstreamer packages and support
2) Force LTIB to Configure the Kernel
3) Within the Kernel Sub-Menu, select:
This is the gstreamer pipeline I used to play the TV stream on my MX6Q SDP:
gst-launch -v dvbsrc frequency=551000000 modulation=7 ! mpegtsdemux program-number=3 ! mpegvideoparse ! queue ! vpudec ! mfw_v4lsink sync=false
==
I could build new kernel with DVB support and load the 950Q driver/firmware dvb-fe-xc5000-1.6.114.fw without any problem. However, I couldn't get any channel information when I ran w-scan. Nor could I run the gst-launch above to get any output on display.
I moved the TV tuner to my Ubuntu box and found it's a newer version which only works with dvb-fe-xc5000c-4.1.30.7.fw. Unfortunately, the 3.0.35_4.1.0 kernel doesn't support this firmware. I tried to port the driver from LinuxTV back to 3.0.35 but the videobuf-core is not compatible. Then, I moved to kernel 3.10.17_1.0.0_beta. I could load the driver/firmware dvb-fe-xc5000c-4.1.30.7.fw and finish channel scan via w-scan but the gst-launch didn't output anything. I attached the w-scan output and the gst-launch messages. Does anyone know how to resolve this issue? Thanks.
Below are the gst-inspect results.

Hi Frodo,
Can you try to build and Rootfs based on YoctoProject Dora version,
As you are mixing different kernel version with Gstreamer Freescale plugins and
multimedia codec libs; fslcodec libs have dependencies on the kernel version
so I will suggest to build a root file system based on YoctoProject dora release.
Follow the instructions from Freescale/fsl-community-bsp-platform · GitHub
to build a Yocto based rootfs; and build fsl-image-gui which will include all FSL
test app and demos.
Regards
Adrian
