• Live video broadcasting in android using front and back facing cameras [on hold]

  1er décembre 2016, par Jun Kim

  This is my first time I am posting a question on Stack Overflow.

  I am currently developing an android application. My goal is to make an app that captures and records video and broadcasts it to other mobile devices as well as web browsers like facebook live.
  (Nowadays, famous apps like Youtube, Facebook, Twitch, Periscope has this function)

  Now, I am just researching what technologies and ways to develop this app.

  I have been researching and reading a lot of blogs and documentations for the past five weeks about FFMpeg, different types of streaming technologies, types of web servers etc. I decided to use MPEG-DASH for my app and nginx server (Nginx-rtmp-module).

  While searching further, I got stuck and confused about how I can possibly capture & record video using internal camera of Android mobile devices.

  I was thinking that I could use MediaRecorder to capture & record (I could hardly find an example using MediaRecorder to record video) and use FFMpeg
  to somehow encode with the certain video and audio codecs to make a container format and send it to nginx server to broadcast other devices.
  But then.... i am not sure if this is the right way to do it...

  My questions is... I would like to know the whole process (in detail if it possible) how I can possible record and broadcast to other devices.

  The whole process of recording video using internal camera that is in user’s mobile device and send the frame to the server to broadcast to other devices seems difficult to imagine for me... Can anyone elaborate ?

  Or any suggestion about how can I reach my goal ?
  Every help would be appreciated.

• Live stream PowerPoint + Video - ffmpeg ? [on hold]

  21 novembre 2016, par Mango

  I’m in the unenviable position of needing to live stream a seminar with one video camera and PowerPoint. We need to switch between the video and PowerPoint at arbitrary times. The switch need not be fancy like a dissolve, and in fact it can take up to three seconds. The audio however must remain uninterrupted and must be synced with both video streams.

  I had the idea of creating a batch file with two ffmpeg commands : one that captured the desktop, and one that captured video from the camera. ffmpeg pushes the video to a local UDP port. Then, it loops.

  A separate ffmpeg process receives the local stream and pushes it to an RTMP server. All I have to do to switch video sources is kill the first ffmpeg.

  This works for video, but I haven’t figured out how to get the audio to sync.

  I’m aware of expensive video production software that provides this sort of thing as a service, but I thought I would see if I could do it open source if possible.

  Any suggestions would be appreciated.
