This particular solution didn't involve the Camera class and only dealt with the MediaRecorder class. After several frustrating hours of searching, tweaking, and testing, I still hadn't come up with a solution.ĭuring this process, I found a code example online for recording video that was much less complicated. The app froze again a couple of videos into the test. I assumed it was a fluke, so I started the app again. The first couple of videos recorded without a hitch, and then the app froze.

I set up my Android device in a little corner and started recording videos. I had the first two major chunks of my problem solved, so it was time to start testing. By setting a maximum duration on the MediaRecorder, the infoListener object is called when the time limit has been reached, which should be used as the trigger to stop/reset the video. setOnInfoListener calls, which could replace the Timer object I was using, and I started using those methods instead. Later I stumbled across the MediaRecorder. Each video was averaging 0.5 MB to 2 MB depending on the amount of light and motion in the video.Īs far as the stop/re-start problem, I initially used a Timer object and found the code worked as long as I called Looper.prepare() in the TimerTask (because it isn't executed on the main UI thread). By testing a couple of video samples, I found that it was best to stick with one-minute videos for now or risk making the files too large and more prone for upload errors.

Next, I had to figure out how to automatically stop and re-start the video recording, as well as decide the length of each video. I will spare you the details for now because I learned there was a much simpler approach, which I will cover later in this post. By following Google's documentation and code samples, I was able to successfully capture a sample video in relatively short order. The first sentence of the documentation states that the two main classes you have to deal with are Camera and MediaRecorder. Google provides a relatively concise guide on properly recording video in Android in the Camera documentation.

In either case, follow the commands below to install it: sudo apt install parole

You might find it listed in the Software Center but that’s not the updated version. You need to add an unofficial PPA in order to get the latest version of Parole. However, it’s a lightweight application that takes less system resources. Of course, it’s just another video player that works – you may not notice any difference “visually” that strikes out. It supports subtitles and you can also choose to extend its functionality using the plugins available. Parole is the default video player in Xfce desktop and offers a good deal of features.
