• How to capture video of VIEW in android

  18 novembre 2015, par Mayur R. Amipara

  we can take screen-shot of particular VIEW programmatically in android same way i want to capture video of VIEW , is that possible ?

  i successfully run third party library ffmpeg but it doesn’t provide such functionality.

  Another way i tried it by taking so many screenshot of view each-second and combine it with ffmpeg , but it is to expensive and taking soooooo much time.

  FINAL QUESTIONS :

  i want to add text that is animating on video, any idea todo this ?

  currently get idea that i can animating textview in layout above video is playing in activity and capture that part of screen programatically, but i fail !

  iphone have functionality for adding text overlay with animation and it is called by AVComposition in iPhone. so, Android have such type of any functions or method ?... googled it for 5 days but not getting any result !

  sorry for my bad english, any point to suggest or any idea that how can i achieve this ?

• Join videos without interruption with removing extra scenes automatically

  19 janvier 2014, par RarLines

  I've tens of splitted videos from a video.

  My english is poor so I will try explain with a simple example :

  The original video scenes like so: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14

  But I had never the original video. I've these videos :

  Video_1.part scenes: 1, 2, 3, 4, 5
  
  Video_2.part scenes: 5, 6, 7, 8, 9 (5 is extra !)
  
  Video_3.part scenes: 9, 10, 11, 12, 13, 14 (9 is extra !)

  When I try to concatenate (or join, merge, combine...etc) these videos with using ffmpeg, the scenes the output file are liked that :

  The output video scenes: 1, 2, 3, 4, 5, 5, 6, 7, 8, 9, 9, 10, 11, 12, 13, 14

  As you can see, when I watch the output video there are interruptions between videos.

  Is there any technical way to join videos without interruption (or nonstop, continuous...etc) ?

  Please note that, my example is so simple. I'm not sure that the splitted videos have regularly extra scenes. If I was sure, I could crop equally. Maybe the length of extra scenes are equal. But I couldn't check.

  Hope you will show an intelligent method. Thanks
