Var destinationPathAndFilename = System.IO.Path.Combine (_workingDirectory, "cat1_out.mp4") The project has a binary FFmpeg file which is installed to the phone directory using the code below: _ffmpegBin = InstallBinary(, "ffmpeg", false) īelow is the example code for encoding video into a different set of outputs: _workingDirectory = Android.OS. However, running the solution doesn't give any output. There's a project on GitHub that demonstrates how FFmpeg is used inside a Xamarin android project. So, I searched for the only way I knew how to encode a video that is by using FFmpeg codec.
I've found encoding to be a bit complicated and there isn't much information available on how this can be done. I then decided to encode the video on the client-side and then send it to the server. I have posted my issues on another thread here Initially, I was using an encoder library on the server-side to encode recorded video but it was proving to be extremely unreliable and inefficient especially for large-sized video files. The requirement of the app is to capture video from the camera and encode the video to send it across to a server. However, there is a lot of code in the Freeflight 2.4 app which takes a lot of time to get the video stream part, but I did not have the time, so I chose for an easier way as I explained before.I'm building an android app using Xamarin. So, if there is someone with this problem, then you could use the source-code of the official app called "Freeflight 2.4", because that one is specially made for Android. Unfortuantely there is no information on the internet about the Parrot AR Drone 2.0 using Xamarin Android. AAR which contains the same files as the Vitamio library in the project I was talking about before and the most important, no errors appeared :) I am using this library because it's using. Because there is this Xamarin Android version known, but that's an old version, so I decided to use the Vitamio library which can be found here.
What I did was trying to use the Vitamio library which Xamarin Android supports. Namely via OpenCV and a library called "Vitamio". However, there was this guy: who made the video stream in two different ways. This could decode the video stream of the drone. Xuggle-Xuggler is a video decoder as well, but specially made for Java only and I am working in Xamarin Android, so I had to find something else.Īfter several weeks I saw a project which uses OpenCV. However, I tried to implement a pre-compiled library into Xamarin Android, but there were errors like DllImport error loading lbavcodec-55': 'dlopen failed: libavcodec-55" not found', so that didn't work. Actually this is in Windows a little bit harder than in Ununtu/Linux.
There is a possiblity to use FFMpeg, but you need to compile this specially for your platform. Good news, because I just solved the problem.
