Is there a change into TelloFPV exiting app behaviour or it's a issue related to my specific Android version/smartphone model ?
That's not specific for your smartphone. If you forget to stop recording, the video is defect or completely not saved. :unsure:

but I prefer old TelloFPV autosave behaviour previous February 14.
Good idea. That's a new topic on @volate!lo 's list - in case that's not already there. :)(y)

Edit:
Another case comes in my mind. The videos wasn't saved when you switch off the Tello. Could it be, that you mistook that?
In this case there was no change in the app.

It's not the case. I always swith off Tello AFTER exiting TelloFPV. I double checked that into DU Recorder Screen Captured Videos.

I have a question.
If i set, as for long range, both frame and bitrate lowest... It will cause low quality foto or this worst performance it's only on video mode?

I'm pretty sure Video and Photo quality are totally isolated one from another. In fact, they have a different settings pannel into TelloFPV.

Cheers.

So could be a good idea so take foto from distance... (y)
Be aware taking photos from distance / bad WIFI signal. As photo transfer waste a lot of bandwith it may happens it takes up to two minutes to download. During this time live video quality will be worse and you can get confused about Tello attitude and position. Take into account you can't cancel photo download process. It happend me sometimes. My advise: always think it over before taking a picture ;)

VIDEO FILE CORRUPTION INTO TELLOFPV

Hi all,

I wanted to tell you I noticed some of my TelloFPV recorded videos saved into "\TelloFPV Videos" folder where corrupted and no playables. This issue happend to me from February 14.

I reviewed Screen captured video files through DU Recorder app and noticed file corruption happend when I exit TelloFPV app and forget pushing STOP recording button.

I had never worried about pushing STOP recording button as previous TelloFPV behaviour on exit used to be: first saving video file, second closing itself. See this old capture sequence from February 11,

TelloFPV old-style not-corrupting exiting mode:
View attachment 3285

I have to clarify when I'm speaking about pushing EXIT button I mean physical capacitive smartphone button:

View attachment 3286

Anyone suffering this corrupting video files issue or just me ?

@volate!lo, Is there a change into TelloFPV exiting app behaviour or is this an issue related to my specific Android version/smartphone model ?

This is not a serious issue once you get used to stopping recording before leaving app, but I prefer old TelloFPV autosave behaviour previous February 14.

All the best.

Raul

I will check this. I changed a few things in that area, and maybe the video write now longer has enough time to do it's cleanup before its forced to exit.

I have a question.

What Raul said. Completely isolated, but Tello doesn't throttle picture transfer so it blocks most of the bandwidth

Yesterday I was flying very close to high tension lines, with strong Wi-Fi interference, since the footbal field is in that place, I made some shots to my son playing, as it says raul it's not a good idea to take photos with Wi-Fi 2019-02-21 16-40-24_level.jpg 2019-02-21 16-40-24_level.jpg interference, I lost I completed the tello control until I finished downloading the photo, those 30 seconds were transformed in about 1 hour :ROFLMAO::ROFLMAO::ROFLMAO::ROFLMAO::ROFLMAO:

Maybe is there any way to manually cancel photo download ?

I can't really cancel photo download but I can stop acknowledging receipt of the data, and Tello will stop sending the data. That won't be an immediate cancel, but should re-enable control within a few seconds
The problem is the user interface....


@anielloz this führer thing isn't funny.

I will pay more attention now but I don't think I was having the issue of lost recordings. I usually just power off the tello after flight/during batt change (Tello FPV rec. auto saves).

On connection lost recording should automatically stop.
On app exit the recording may have been stopped the hard way in recent releases, depending on individual phone timing. That will be fixed in the next release

As to stop photo download... As mentioned the problem is the user interface. I don't want to introduce a button to cancel a download, and I don't like these "Cancellable" messages like Ryze Tello app has for cancelling the auto landing. That would not work anyway for VR mdoe.
I will instead cancel photo download on "Stop" button. Since its a bit of a hidden function I'll add a photo download message that gives a hint to use "Stop" to cancel photo download. That allows it to use this function for both VR and normal FPV mode the same way.

I've added your new App to the compatibility spreadsheet:

Tello Compatibility
My gamesir ts1 will not connect via BT? I have the controller paired up and paired with my phone and powered on but when I try to select the controller from within the app I only get an "Onscreen" option. I have tried to connect different ways (eg power app on 1st. ect) but no luck. My phone does not have that otg cable capability so that's not an option. I can connect the contoller via BT to the atellopilot app but I would like to use this TelloFTP. any suggestions would be greatly appreciated.

Was similar by me.
Have you the latest update installed?

Then try to delete the connection and pair new. If this doesn't work, reboot your cell.
Good luck!

Try un-pairing it with your phone. It should not need to be paired.

You have to connect. The first time with a special key-combination (T1s). I guess that's what the button "pair" is for (T1d).

Great. I like the way you will solve both issues (y)
