LectureVideos is a screenshot extension of LectureNotes for recording video and audio while taking manual notes using LectureNotes.
It was designed with an academic (or school) user in mind, such as a teacher who uses it to produce tutorial videos or to record giving his class using LectureNotes (by writing on the device and projecting the screen content for the audience) or a student who uses it to prepare the tutorial videos for their classmates. However, it has many potential applications outside of academia, for example in business or technology.
Its main targets are tablets with Android 4.1 or later.
NOTE: LectureVideos cannot be used on its own, it is designed to serve as an extension of LectureNotes and can only be used in conjunction with it. If you want to record video and audio while taking handwritten notes, launch LectureNotes and start audio and video recording there, the video and audio files will be stored in the corresponding notepad directory.
LectureVideos uses the Android MediaCodec API available with Android Jelly Bean to encrypt audio and video files, so Android 4.1 or later is required. However, as Android MediaCodec behaviors differ significantly from device to device, LectureVideos may not work on any given device.

*only requires minimum permissions and no internet connection (we respect your privacy!)
* allows viewing content and audio signals to be recorded while taking handwritten notes using LectureNotes (root permissions are not required)
*allows display content and recorded audio signals to be replayed using PlayNotes
* allows to multiplex display content and audio signals recorded in an MP4 container file using PlayNotes (Android 4.3 or later devices only)
Possible problem: For good audio quality, it is advisable to use an external microphone, especially when taking notes with a stylus with a hard tip in parallel (the noise that the tip causes on the screen of the device and human voices are in the same frequency range and it cannot be filtered reliably).
