    SDK "streamon" format

    @xristos If you only want to preview the video, you don't need to convert the image to a Bitmap. You can use a `SurfaceView` and pass it's surface to the `MediaCodec` directly so that it decodes into the `SurfaceView`. That's the best way for video preview. In my case I was doing video analysis...

    SDK "streamon" format

    Nice! Seems like generally useful info.

    Video streaming from tello

    I guess app inventor is just high level coding really. You should look specifically for threads related to app inventor directly.

    Getting started

    Programming it is not as easy as it should be, but there is actually resources out there. See this demo which shows some functionality: dji-sdk/Tello-Python Also, click the Wiki at the top here for more info.

    Video streaming from tello

    You want to do it in code or through the given app?

    SDK "streamon" format

    While in my case this doesn't matter, but when I was looking at packet headers, I did see that there is some pattern to them. like you said some start with something like 00 00 00 015, and others with 00 00 00 013. That's what I recall.

    Seems it try’s to flip T startup

    When this happened to me (after a crash), doing the IMU Calibration in the Tello app fixed the problem.

    Liftoff without using "liftoff" command

    Something I find effective is immediately calling rc 0 0 -40 0 after liftoff. That makes it seem more stable after lifting off. That's not like the angled sticks behavior, but it's still better than a regular liftoff.

    TELLO DOES NOT MOVE

    What is the "go" command? I don't see it on the list of commands.

    Liftoff without using "liftoff" command

    Yeah, I've tried that now, even though that doesn't correspond to an angled stick. Likely they are just calling a different command when the sticks are angled like that.

    Liftoff without using "liftoff" command

    Yeah, I tried that, and other variants but no luck. Likely the official Tello app is calling a different command when the sticks happen to be at that angle.

    SDK responses

    Also, do you know how to start the motors without calling "liftoff"? In the Tello app, it is done by holding sticks at 5 o'clock and 7 o'clock. I tried "rc -50 50 50 -50" and other variants of that but I'm not able to get the motors to spin up without calling "liftoff"

    Liftoff without using "liftoff" command

    Do you happen to know what command that translates into. Is it "rc -50 50 50 -50"?

    Liftoff without using "liftoff" command

    Awesome, I will have to try it!
  15. H

    Liftoff without using "liftoff" command

    I don't really like the behavior of the built-in "liftoff" command (Fly up and then hover ~1 meter above the ground). Is there a way to spin up the motors without that command? I would like a command which will immediately hover the drone (If taking off from the hand for example).
