./MatriceSeries_ConfigTool --usb-port /dev/ttyACM0 --c./MatriceSeries_ConfigTool: error while loading shared libraries: libavcodec.so.57: cannot open shared object file: No such file or directory

Hello,

I have been trying to activate the flag that let the drone fly with the USB A- USB A cable connected but I am getting the following error:

./MatriceSeries_ConfigTool --usb-port /dev/ttyACM0 --config-file /home/anuc/.ros/UserConfig.txt --usb-connected-flight on ./MatriceSeries_ConfigTool: error while loading shared libraries: libavcodec.so.57: cannot open shared object file: No such file or directory

Everything in the SDK work nice but the MatriceSreis_ConfigTool, it seems like the only package that depends on libavcodec.57.

I am running this in an intel Nuc I7 with Ubuntu 16.04.

dpkg -l "*avcodec*" | grep ii
ii  libavcodec-dev:amd64            7:2.8.17-0ubuntu0.1 amd64        FFmpeg library with de/encoders for audio/video codecs - development files
ii  libavcodec-ffmpeg-extra56:amd64 7:2.8.17-0ubuntu0.1 amd64        FFmpeg library with additional de/encoders for audio/video codecs

Hello,

I know, but the problem it's that the version installed in Ubuntu 16.04, the version in which you have runned the test for the Onboard SDK ROS, is libavcodec56. So it's quite surprising that the configTool depends on verision 57.

Ffmpeg is found, but 56 version. -- Found FFmpeg installed in the system. -- - Includes: -- - Libraries: //usr/lib/x86_64-linux-gnu/libavcodec.so;//usr/lib/x86_64-linux-gnu/libavformat.so;//usr/lib/x86_64-linux-gnu/libavutil.so;//usr/lib/x86_64-linux-gnu/libswscale.so;//usr/lib/x86_64-linux-gnu/libvorbis.so;//usr/lib/x86_64-linux-gnu/libvorbisenc.so;//usr/lib/x86_64-linux-gnu/libtheora.so;//usr/lib/x86_64-linux-gnu/libz.so

@dji-dev any news?

I followed this link: https://developer.dji.com/onboard-sdk/documentation/quickstart/development-environment.html

And when ffmpeg is installed as you said in the tutorial I get that the library is the newest version available for Ubuntu 16.04, which is the version in which you have done all the tutorial...

1. Install Development Tools

   C ++ compiler: GCC 5.4.0/5.5.0 version CMake: 2.8 and above Linux: Ubuntu 16.04 (If you need to use advanced sensor functions, please use the Libusb library)

sudo apt-get install libavcodec-dev libswresample-dev
[sudo] password for anuc:

Hello,

Any updates on that @dji-dev? I am facing the same problem.

@Avistadrone, did you manage to resolve it?

Thanks,
