Epoccam Feature Requests for Kinoni?

  • Dear Sami,

    RE: OSC: for sure I can be of help here. And while one could attempt to create a robust OSC implementation, really it would be as simple as listening on a UDP port for a particular message and decoding it.
    For example, let's say we were to have a command that would select the camera. The OSC message would look something like this:
    /epoccam/cam-select ,i 1
    There are three parts to this message
    1) The ASCII OSC Address = "/epoccam/cam-select" (no quotes obviously)
    2) The ASCII "type tag" = ",i" = one 32-bit integer to follow
    3) The 32 bit integer value (big endian)
    Because the OSC Address and type tag are padded out to a multiple of 4 with null bytes, in reality it looks something like this
    where the bolded 0s are bytes with a value of 0, and nnnn are the 4 bytes that make up the actual value being sent along with the message. So, you could simply to a byte-by-byte comparison of the OSC address + type tag to see if it is a message of interest to your app. Then you would just grab the next four bytes, convert to little endian, and use the value to do whatever you need to do.
    So, mostly what we're talking about is adding a UDP port input to the app  and a table of all the OSC message + type tags you accept. Upon receiving a message, you can run through the table, compare the incoming message to those you actually handle, and take action if you find a match.
    You can actually mock up these messages in Isadora, and send the messages to local host. They will appear in the new monitor window (available in the [pre-release version](http://troikatronix.com/download/isadora-pre-releases/)) so you can see a byte-by-byte breakdown. You'll see something like the message shown in the attached picture.
    Hopefully that sheds some light on how you might implement OSC in Epoccam. One argument for making this effort is that adding interactive control would give your app a feature that would set it apart from all the competitors. People using Isadora, but also using software like MAX, vvvv, PD and others would be pretty interested, especially if you add control for brightness, exposure, focus, etc.
    Best Wishes,


  • multi-camera support: "Should we create Syphon sources dynamically when cameras are available or have 3-4 static Syphon sources that provide black image until EpocCam is connected?"

    I prefer 3-4 static Syphon sources that provide black image until EpocCam is connected>
    Question to Sami: EpocCam worked for me on Skype until I downloaded the Skype update. Now Skype does not find EpocCam. Since this is not an Isadora issue plz tell me the proper place to ask this question. thank you.

  • @Kinoni
    Dear Sami I've being using it since last year on Android with Mac although sometimes it's difficult to get it to work or it looses the signal for no reason... thanks for letting me know that the new features will be in both platforms

  • @vanderzee:

    We are aware of issues with latest Skype and work on fixing them. For some reason Skype keeps changing their behaviour with video devices between releases - and then we do trial and error to see what works. Sorry about the issue.
    I agree our Android is not as good as iOS app, on some devices it just crashes or quality is bad. There are so many Android devices that work differently, it is impossible to test all of them.

  • Just to a note to Sami to say, first, thank you for taking part in this discussion, and second, as you can see, Isadora users are not shy to share their ideas. ;-)

    As a developer I know what it means to add and test features. It would seem that the central requests above are 1) make sure it works on all versions of Mac OS (even if that's done with Syphon) and 2) add the ability to have multiple cameras with a fixed set of Syphon outputs. Maybe that would be the key thing to consider.
    Best Wishes,

  • Mark, I fully agree. First we need to provide an application with Syphon output, it should work on OS X 10.6 and later.

    I can also test osc (use it a lot) an have ipad2 and iphone 3 so I can test multiple cams. i'd love epocamm to send o/c too (why not imagine the iphone sending the image and the o/c data like accelerometer and or gyro) to interact with movement on the images sent by the same person....

  • Tech Staff


    Me like that idea. Well all above sounds very promissing.


  • @Armando: Sorry I missed your comment earlier. Yes, It is easy to capture accelerometer and gyroscope (device rotation) data and send using OSC messages. We will look into OSC after we have implemented Syphon support and multi-camera Syphon support.

  • syphon YES, dreaming of mega photo functions 100 fx filters, OSC touchVIZ dose this very neat. I know its a lot, just to inspire ….

    best wishes


  • @Kinoni
    what's happening most of the times, is that although I can always see the Epoccam window (computer next to phone) in Isadora, I don't see the camera image (neither on the phone) produced by the Samsung phone on Android...
    Any ideas Sami?

  • My 2c. 1) Video resolution. We can do 720p video or even 1080p video. What are your requirements for video resolution, it is the higher the better? HD resolution also require more wireless bandwidth to be transmitted. The more options the better. There are times in Isadora when I don't need more then 320 x 180. Other times I'll use 720x 480. . . 2) USB-support. While Apple does not officially support transferring data over USB for third-party applications we have found a way to do this. Compared to WiFi USB has lots more bandwidth, but being plugged to cable means camera is next to Mac. Yes. Plugging it may well desirable in some situations. 3) 60 frames per second capture. There are also rumors next iPhone could do 120 frames per second capture. Would it make any sense use have these high-fps videos in Isadora? Very much so, yes.

  • It has taken like forever but finally we have a Mac OS X beta-version with Syphon support. Sorry about slow progress. You can download the app from http://www.kinoni.com/EpocCamSyphon.zip

    Any feedback is welcome. Next step for us is adding multiple cameras, that should be matter of weeks - not months.
  • Beta Platinum

    Thank you, but I cant get it working on iPhone 4 IOS7.0.3 and OS 10.9

  • @feinsinn:

    Ouch. What exactly is the issue? No connection? We are testing exactly the same setup OS X 10.9 and iOS 7.0.3\. In fact we are using our latest iOS app that is currently in App Store review and available later this week. But that should make no difference I guess.
    I forgot to mention that app should work on OS X 10.7 Lion and later, probably not on OS X 10.6 Snow Leopard.
  • Tech Staff


    Works great for me on OS X 10.9 and iOS 7.0.3. But unfortunately if the computer is connected to the same network via cable it does not work, it has to be on WiFi.
    Then downloaded the EpoCam HD version and after a few seconds (varies 10-30 seconds) the EpoCam Viewer Syphon app on the Mac stops showing the incoming video and says "searching network ...". Closing the iPhone app and reopening it gets the connection back for 10-30 seconds. This doesn't happen with the free EpoCam iPhone app.


  • I'm unable to get mine working on Windows since the latest update. I've been in touch with Kinoni, but haven't heard when there might be a fix.  Too bad, I was planning to use it for a show next week!



  • Beta Platinum

    @Kinoni I use also Epoc Cam HD. The same like Michel: "searching network ..."

  • Tech Staff

    @Kinoni @feinsinn

    With the Epoc Cam HD update that appeard in the ios app store today the "searching network ..." problem seams to be solved.


  • Beta Platinum

    hm, updated, but still the same "searching network..." in the EpocCam Viewer Syphon, after one minute i get a message on the side: epoc cam hd for ios7 is connected video size 1280 720, but its stays black in the viewer syphon
