I've been trying out the intel media sdk for quite sometime. The performance overall is excellent, especially with 4k.
What I did not understand is, I could not run few samples on many NUCs available with me. To be specific , I needed sample_camera application for testing the colour correction filter. This actually worked on only one system.
The following table lists the results with various NUC systems
|Setup||Display Driver version||SDK Version||Test Results||Comments|
Intel i7-3770 CPU @ 3.4GHz
|Intel HD Graphic - 4000
Driver Version : 10.18.10.3958
|1.13||Fail||This plugin was never supported in 1.13. So, expected result - Fail.|
|Intel i6-5250U||Intel HD Graphics - 6000
Driver Version : 126.96.36.19931
|Intel i7-5557U||Intel Iris Graphic 6100||1.17||Fail|
|Intel (SkullCanyon)|| Intel Iris Pro 580
Driver Version : 188.8.131.5244
|1.17||Pass||This has the highest version of Display Driver - 4444 -- though not the same graphic card.
Could this be a requirement?
As you can see, I'm able to run the sample_camera application on only ONE system. Which is surprising!
Another thing to note : I have tested with the latest Release ( intel media sdk, R2 ). Results are still same.
- Could someone from intel give an explanation on this?
- Can you please list out what hardware you support ?
- If this is not a hardware issue, then what else could the problem be? Do you need any logs? say, registery or anything that be helpful.
P.S: Tests are performed with utmost dedication. We used sample binaries supplied in the sample at the time of installation. We have also compiled the samples as it is for our own validation. In either case, results are same. Since at least one case is working, I suppose, I have a valid input for the sample to run.
You have previous Media SDK release (1.17 API version).Try to update Media SDK to 1.19 API version (Download Media SDK 2016 R2).
Intel i7-3770 CPU @ 3.4GHz is a 3rd generation of Intel CPUs called Ivy-Bridge that is unsupported by RAW-accelerator plugin. We support upper than 4th generation (Haswell) of Intel processors with integrated graphics.
What errors do generate the sample_camera on Intel i6-5250U and Intel i7-5557U? If it doesn't work after updating Media SDK, you can try to install SkullCanyon's driver on this machine.
As I mentioned in my question, I have tested with the latest media sdk ( version 1.19 ).
Also, I understand that , Intel i7-3770 CPU is not supported, I've already mentioned that in question.
The error I get is - MFX_ERR_NOT_FOUND ( error code : -9 ). When I debugged, I found out that this is actually generated when the application is not able to load the plugin.
I'll update the driver and let you know the results.
It's strange. This problem should be solved by a right combination of latest driver, sdk and samples. Please run mediasdk_system_analyzer tool to check supported API versions and implementations. If you see that HW implementations of the latest Api versions (1.8 and 1.9) are unsupported, do the following steps (order is important):
1. Uninstall all MediaSDK and Media Server Studio versions from your computers.
2. Install the latest driver (you can use Intel(R) Driver Update Utility for this reason)
3. Install Media SDK 2016 R2.
4. Download and run the latest samples from github: https://github.com/Intel-Media-SDK/samples
