Tello_video is not working.

zsole19 commented 5 years ago

Is not able to include the package h264 even if is it in the correct folder, do you have any suggestion?

File "D:\Tello\Tello-Python-master\Tello-Python-master\Tello_Video\tello.py", line 5, in <module> import libh264decoder ImportError: DLL load failed: The specified module could not be found.

hanker-lu commented 5 years ago

Hello, have you run a one-click installation script？ If so, you can try manually putting h264decoder.pyd in the site-package folder.

how exactly do so, as I m newbie.

[upate] fixed by running in python 2.7 (including installation)

@hanker-lu Did you mean libh264decoder.pyd in site-packages?

I am having the same problem importing lib264decoder when I run main.py, Even the install.bat for windows doesn't seem to be working very accurately. So I manually pip installed all the dependencies, but the h264decoder isn't built. @hknakata how did you solve the problem?

johnadams2076 commented 5 years ago

Works for me. Check Pose Recognition in video. https://www.linkedin.com/feed/update/urn:li:activity:6498225445987852288 Okay. As a workaround, For Win-64, following files need to be downloaded into your C:\\Tello-Python\Tello_Video\install\Windows.

https://www.python.org/ftp/python/2.7.15/python-2.7.15.amd64.msi https://bootstrap.pypa.io/get-pip.py https://ffmpeg.zeranoe.com/builds/win64/shared/ffmpeg-20180825-844ff49-win64-shared.zip https://nchc.dl.sourceforge.net/project/boost/boost-binaries/1.68.0/boost_1_68_0-msvc-12.0-64.exe https://download.microsoft.com/download/2/E/6/2E61CFA4-993B-4DD4-91DA-3737CD5CD6E3/vcredist_x64.exe

Type "command" in the search bar and right click. Select "Run as Administrator". cd to C:\\Tello-Python\Tello_Video\install\Windows. type "install"

It will extract and put files in the appropriate directories. Now check C:\Python27\Lib\site-packages. Pyd file along with several dlls must be present. Run main.py.

Hope this helps.

As for 3.6, I tried cmake for h264decoder. I got it compiled. Linker Ld.exe was looking for 3 dlls. I did not go further. I switched to the above method.

Lets explore what's possible and beyond.

kesaroid commented 5 years ago

Still no luck. The install.bat file keeps crashing. Opens command prompt, asks for the admin rights and then closes every time. I have tried everything. Maybe it's a bug in the installation file itself? Did you get it to work with win-64 itself? The same goes with install_manual and even uninstall.bat for that matter

Unpack ffmpeg-20180825-844ff49-win64-shared.zip Unpack boost_1_68_0-msvc-12.0-64.exe

Go to C:\\<Path to extracted ffmpeg\bin

Copy all dlls to C:\Python27\Lib\site-packages

Go to C:\\boost_1_68_0\lib64-msvc-12.0

Copy boost_python27-vc120-mt-x64-1_68 to C:\Python27\Lib\site-packages

Copy C:\\Tello-Python\Tello_Video\h264decoder\Windows\x64\libh264decoder.pyd to C:\Python27\Lib\site-packages

Now run main.py. Let me know.

Did the exact same thing, but unfortunately ..

Is your python Base interpreter pointing to C:\Python27\python.exe ?

kesaroid commented 5 years ago

Is your python Base interpreter pointing to C:\Python27\python.exe ?

yes, yes it does. what else could I try to figure this out? Should I try installing python for x86 and try h264decoder with that?

For win64,i have pushed new commit about some dll needed to run tello_video.You can try to copy all these .dll/.pyd to your site-package file and run the program again.

In addition ，you should run the vcredist_x64.exe to setup the vs2013 dependency.

kesaroid commented 5 years ago

@hanker-lu Thank you so much. It's working just fine except for a minor h264decoder error [h264 @ 0000000013786800] non-existing PPS 0 referenced [h264 @ 0000000013786800] decode_slice_header error [h264 @ 0000000013786800] no frame!

Hi， please check if you run the vcredist_x64.exe to setup the vs2013 dependency.

@hanker-lu, yes I have done that. I have done everything that is written here above. I don't know what else could I do.

Should I try to build the h264 library for my self?

sriranjanr commented 5 years ago

Getting the following error. I copied libh264decoder to site-packages in python folder but still the import module error

in <module> import libh264decoder ImportError: DLL load failed: The specified module could not be found.

sriranjanr commented 5 years ago

I ran the install.bat file. It was unable to install pip, I ran get-pip.py and then it installed pip. Also it was unable to install boost. So I downloaded boost and boost is just like a large collection of files which got stored in c:/local/boost1_68_0. What should I do with these boost files? I am still getting the same import libh264decoder error. Is there not an easier way to read images one by one from the Tello edu drone..?

sriranjanr commented 5 years ago

Could anyone help me to get the tello_video program running. I get libh264 error?

tobyloki commented 5 years ago

I am getting the "libh264decoder" error as well. I also agree that the ffmpeg is not downloaded correctly, and that install.bat needs to be updated.

I also encountered the same issue with ffmpeg. In addition, I found that libboost is not installing properly as well.

Erro message "msxml3.dll: Access is denied" persists even after I removed md5 testing.

How to recive tello video stream in windows? MD5 mismatch, decoder error and this is still not perfect. Please someone from tello community make it accessible

hippoduck commented 5 years ago

I bought the Tello so I had an excuse to play around with Python, but this has completely put me off. Why is Python so difficult to get working? It's way over complicated.

hippoduck commented 5 years ago

Ok, I fixed this by extracting tello_video_dll(ForWin64).zip which is in the root directory of this project into C:\Python27\Libs\site-packages.

Make sure you're using x64 of all your installations if you still have issues. I had x86 of python which caused problems for me.

If you can't get it working, I wouldn't worry too much, it's super buggy and barely works anyway.

projectdrone2 commented 4 years ago

@kesaroid , I have the same issue "[h264 @ xxx] non-existing PPS 0 referenced [...]". Have you managed to find a fix?

cozmobotics commented 4 years ago

I have the same problem. After trying in Windows,I tried in a Virtualbox where I have installed Mint 19_1. I started the Linux_install.sh. I get a lot of messages, in the end I got:

I attach both logfiles. CMakeError.log begins with

The output was:

I'm quoting from the FAQ:

In the latest commit, a zip named 'tello_video_dll.zip' is provided (for win64 only), which includes the required files related to boost, ffmpeg, libh264decoder, vs2013 compiler.If you want to install it: First, double-click to run vcredist_x64.exe (vs2013 compiler installation package) to install.Second, copy the remaining files in the folder to the C:\Python27\Lib\site-packages path. (With this zip, you can avoid the online download and partial installation, but note that the files in this zip are only available for win64! nAlso, like numpy, matplotlib, pillow and opencv-python you still need to install with pip by yourself.)

This might help some of you guys
