    WIFI+S Range Extender vs Xiami WIFI Repeater and Tello Channel choice

    I don't remember any commands to do with regions. I know my app never sent anything like that. If there was like that in my code it may have come from examining the original Tello App logs. There was a lot of Chinese that I auto translated. That FF firmware sounds interesting. I wish we...

    SDK "streamon" format

    NAL = Network Abstraction Layer. The 00 00 00 01 headers.

    SDK "streamon" format

    TelloLib can save out just the raw .h264 stream with all the NAL stuff removed. Running one of those files through ffprobe says that it is encoded with the Main Profile. Input #0, h264, from '2018-13-5--19-21-54.h264': Duration: N/A, bitrate: N/A Stream #0:0: Video: h264 (Main)...

    SDK "streamon" format

    I never actually tried WebRTC. I got stuck on the need for a server to setup the initial connection. And, like you, I had trouble finding a way to convert the video data to WebRTC streams. At end of maybe a month of trying to do what you are doing I came to these conclusions. - It was too...

    SDK "streamon" format

    I would try to use the media streams. They will deal with the other part of the problem which is getting the frames displayed as quickly as possible. The browsers media player isnt designed for that. Unless you really are able to decode to canvas. Even then make sure the decoder supports...

    SDK "streamon" format

    Low latency is a whole other story. You'll find that nothing happens at as-soon-as-possible. Its all designed to provide smooth playback not real time. If you want low latency you need to use WebRTC. And that will also make your head hurt.

    SDK "streamon" format

    I looked at maybe half a dozen different options, I don't remember trying that one. It doesn't seem to work for me in chrome. The issue with emscripten approaches was usually speed. Because of Websocket UDP you can't directly connect to the Tello from the browser anyway. So at the end of the...

    Tello Video Web Streaming

    Its been forever since I did this. Maybe I have the command wrong. But if ffplay plays the stream then ffmpeg should too.

    SDK "streamon" format

    I have been down most of these paths. I was trying to get the raw video to play in a browser window but never managed to make it work. No matter what I did I always came back to needing a server to take the video and do something with it. It seems you are looking into how to decode the video...

    New Tello-EDU SDK

    No. I looked into it but never seriously tried. Since then I saw a thread here somewhere where someone tried and it failed. I don't remember the details.

    Tello Video Web Streaming

    As I said in the #2 post I got minimum delay by using ffmpeg instead of ffplay. ffmpeg -i udp://<server ip> -f sdl "window title"

    Using Fatshark with iOS and Tello

    Nice! Wish I thought of that battery arrangment.

    Tello + FPV camera.

    With the shape of the battery and the location of the props it wound up being best to Velcro it to the end of the tello battery in the back. It didn't look elegant. Thats why the wired in approach seemed best.

    Tello + FPV camera.

    Its linked in the post just above this one. The power was a lipo battery you can see dangling in the video. But someone else did a wired in adapter. See the previous page for a pic of that.

    New app: TelloFPV for Android

    I'm not saying you are wrong, but the proof is to look at them side by side or compare the bitrate with a tool like ffmpeg. In my tests I was getting about 1/3 the amount of data that the official app was getting. Note you have to test it in fairly heavy bitrate conditions to really see the...
