LectureVideos

LectureVideos


LectureVideos is a screencast extension to LectureNotes for video and audio recording while taking handwritten notes using LectureNotes.

It has been designed while having a user at university (or at school) in mind, for instance a lecturer who is using it for producing tutorial videos or for recording her/his lecture while teaching using LectureNotes (by writing on the device and projecting the screen content for the audience) or a student who is using it to prepare tutorial videos for fellow students. However, it has many potential applications outside university, for instance in business or technology.

Its major target devices are tablets with Android 4.1 or later (it is developed on a Samsung Galaxy Note 10.1, an Asus Nexus 7, a Samsung Nexus 10, and an Asus MeMO Pad).

NOTE: LectureVideos cannot be used on its own, it is designed to serve as an extension for LectureNotes and can only be used in conjunction with it. If you wish to record video and audio while taking handwritten notes, launch LectureNotes and start video and audio recording there, the video and audio files will be stored within the corresponding notebook directory.

LectureVideos uses the Android MediaCodec API that became available with Android Jelly Bean to encode video and audio, so that Android 4.1 or later is required. It has been carefully tested on a Samsung Galaxy Note 10.1, an Asus Nexus 7, a Samsung Nexus 10, and an Asus MeMO Pad. However, since the behaviors of the Android MediaCodec differ significantly between devices, LectureVideos might not work on a given device.

LectureVideos entirely relies on the Android MediaCodec and does neither contain any codecs nor any other encoding, decoding, multiplexing, or demultiplexing code (mainly to avoid legal problems).

User feedback:
We would love to hear from you, please send feedback and feature requests to us by email (devel [a] acadoid.com). If you encounter a problem with the app, please email us and we will do our very best to fix it quickly.

Major features:
* requires only minimal permissions and no internet connection (we do respect your privacy!)
* allows display content and audio signals to be recorded while taking handwritten notes using LectureNotes (root permissions not required)
* allows recorded display content and audio signals to be replayed using LectureNotes
* allows recorded display content and audio signals to be multiplexed into an MP4 container file using LectureNotes (devices with Android 4.3 or later only)

Possible issue: For good audio quality, it is advisable to use an external microphone, in particular when taking notes with a stylus with a hard tip in parallel (the noise that the tip causes on the device display and human voices are in the same frequency range and the former cannot be filtered away reliably).

Recent changes:
* several minor improvements
* Portuguese, Spanish, Italian, and French localizations added (languages of the largest user proportions after English, German, and Korean, other languages will follow in order of user proportion)
* optional video/audio time offset added
* more devices supported
* Korean localization added (language of the largest user proportion after English and German, other languages will follow in order of user proportion)

Great App and Great Support I've been using this app to record some educational videos, and as many others have said, it's a terrific app. I mainly want to comment on the support I received from the developer. Recently, I encountered a problem with the app on my somewhat-uncommon phone. I reported the error message I was receiving via email to the developer, and I received a reply back in less than 24 hours. He send me a debug version of the apk to install on my phone and asked me to send him the log file output so that he could debug the problem. Long story short, he resolved the problem within about 24 hours and made plans for an immediate update to the app store. I felt that this was superior customer service for an app that I paid so little for. I've evaluated a lot of different options for online course/lecture recording, and this one is the best. I hope that you will buy this app and support this terrific developer.

Excellent A very practical and useful app for both student- and teacher-type of users. However, tutorials or help resources are difficult to find and scattered over various places. Maybe list all help resources at one website!?!

Is it being resolved? Looks diametrically opposite to lecture notes. I gave 5 star to lecture notes and 1 to this. All videos get recorded with 0 length. Hope it is not Waste of money. Tried all options. Need help...... (Edited my feedback after few months from here further)...Long back I was offered a refund by developer(developer contacted me and was very helpful), since this problem seems to be due to google's policy. However I continued expecting either google to change an unnecessary policy or atleast developer to develop this small resolution (involving storage in Ext SDcard). Updates are coming but I am not getting a solution. But my love for lecture notes(other product) makes me to live with the expectation still. Atleast can such a loyal paid customer know an expected date??

Love the app but issue with exporting to YouTube. Looks like a bug as it starts and 2 seconds later it returns to previous frame.
