Video plugin needs fix?

Hi,

I was trying to get video plugin working but it seems to crash very easily, or display black video image unless I drag around the window. The most annoying thing is that it crashes to desktop every time I try to get the video played full screen.

I have a link to the video I use along with the accelerometer / gyro data that was recorded with it here:
http://rapidshare.com/files/237943857/example_5dof.zip

Inside the zip file there is a photo of the settings I use to import the txt file that contains the motion data.

To understand better what I try to do take a look on the following video:

For datalogging the motion data I use the Sparkfun Logomatic v2 and for sensors the 5DOF IMU:

Anyone tested this yet? Can you confirm the crashes (like when pressing to view the video fullscreen?

Or it is my windows video codecs issue? :


Regards, Thanos

Oh, Thanks!!!! Disabling the overlay option in mediaplayer's options, really did the trick!!!!

The video plugin is no more crashing with fullscreen button!!! Thanks!!!!!! :


BTW, the example zip file link works fine !! But it doesn't matter, I'll probably make a new one with my GoPro Hero Wide camera mounted on my motorbike... :lol:

I need to incorporate this into our trip to the amusement park this summer! :yippiee:

Did this example make anyone wonder if it's possible to acquire motion data from a pre-recorded video segment that can be sent to the motion platform. There is recognition and motion tracking software in some of our surveillance systems, but not sure it can be possible to interpret the motion based only on what is seen. The human brain can do it, but we're still behind that learning curve I'm sure.

Hi sterlingchristopher,

Why trying to add motion data to existing videos, while you can shoot your own footage with real motion data captured realtime synchronized to your video?

Imagine that you can just take your camera and the datalogger/sensors to your vacation and film anything you like, from car or bike sports, rollercoaster rides, windsurfing, flying airplanes or diving sessions with waterproof equipment!!!! Then you can just share with your friends some of the cool parts back home on any DOF motion platform you have available!!! :snack:

It gives a new meaning to the sharing memories term!!!!! :brows:

Hi Rene,

The rapidshare link http://rapidshare.com/files/237943857/example_5dof.zip contains three files in it. One is the test video itself (Pict2756.avi) and the other you need is the TXT file called LOG07.txt that contains the motion data.

In order to make it work you should open the Video-plugin and load first the video Pict2756.avi. Then from the menu of the video-plugin window you must Import the LOG07.txt. In the configuration screen that appears when importing motion data file you have to choose some settings that declare the sample rate of the captures data and the amplification of its values if they are too low. These settings can be seen in the third file inside the zip called test motion video settings.jpg

You may need to swap the Longitude and lateral data lines, as I had connected differently the sensor board from the default values in the video plugin. BTW in this test video I used a normal narrow type video camera, not the GoPro Hero Wide

About the Logomatic and the 5DOF IMU... The complete device consists only by these two little boards, connected to a 3.7v lithium from a mobile cell phone!!! The battery is charged over the USB cable when the device is off.



If you turn on the device after you connect it on computer USB port it appears in the drives like a flash disk drive that gives you access to the MicroSD card contents. Now the really cool part is that Logomatic creates a TXT configuration file that is used to determine the number of ADC channels used and the rate of sampling. For 5 channels I could achieve 250hz sampling rate that equals to 4ms delay in profiler video plug in!!!! Almost as fast as my AMC cycle rate!!! The best part is that Locomatic has onboard voltage regulator and output pins for powering external 3.3v compoments. So the 5DOF IMU is powered through the Logomatic from the same battery!




Here is the Logomatic's configuration TXT contents:

Code:

MODE = 2
ASCII = Y
Baud = 4
Frequency = 250
Trigger Character = $
Text Frame = 100
AD1.3 = N
AD0.3 = Y
AD0.2 = Y
AD0.1 = Y
AD1.2 = N
AD0.4 = Y
AD1.7 = Y
AD1.6 = N
Saftey On = Y

I bought both Logomatic v2 and 5DOF IMU from Sparkfun relatively cheap from other similar products around:

Logomatic v2 Serial SD Datalogger:
https://www.sparkfun.com/commerce/product_info.php?products_id=8627

IMU 5 Degrees of Freedom:
https://www.sparkfun.com/commerce/product_info.php?products_id=741

And you will also need this cable for the JST mini power connector of the battery:
https://www.sparkfun.com/commerce/product_info.php?products_id=8670


You can use any MicroSD card up to 2GB with logomatic. These cards are quite cheap these days!

I still need some help with the video plug in. It keeps crashing for no reason on random. Here is the error message it gives, before the video-plugin closes:





And another issue that is even more important at this time is how to properly sync the video with the data. It seems that even If I give the correct values in seconds in the offset box, it keeps the same wrong sync. What is used in Offset value? Seconds, Microseconds? What? And will negative values work too?

@ Thanos,

That is an excellent point, being able to relive or share the experience on-demand is very exciting. I need to get a working platform off of the ground and start data-logging this summer. The SCN5 setup seems great, but I don't want to stop there.

I can really see this community benefit from sharing platform setups, but actually now having the ability to share synced motion and video data is amazing :

Thanks, Chris

Hi!
I didn't want to create a new post & this thread seemed appropriate.
having some challenges with the video editor 2.0;
save project is pressed and a file is created with the extension .fs2 (same directory/file name as the video);
when this file is double clicked the video editor opens but no video or axis data appears;
here is an example of the beginning of a .fs2 file using only the roll axis:

[FileData]
Path=C:\Users\John\Desktop\Simtestvids\testvid1.wmv
Duration=1159
[Data]
Block1=000000000000000000AB0000000000560000000000000000000000AB000000000056000000
0000000000000000AB0000000000560000000000000000000000AB00000000005600000000000000

the actual loading of the video and axis editing seems to be fine...
here's a screen shot at the time of saving project


have tried a number of different videos in different formats - same problem;
also, X-Sim Wiki refers to the axis data file as an .fsm type file - not a .fs2 type, and indicates
Also you have to load the Video plugin .rn2 simulator profile file in the profiler2
guess I'm generally confused about using the video editor....

any ideas would be much appreciated
thanks!

ps - OS is Vista 64
