• Automatic save Printscreen video

  18 février 2014, par Erik Van de Ven

  I would like to save a screenshot of a video, as thumbnail image, as soon as someone uploads a video. They told me this is only possible on Windows servers. But now I read something about http://www.ffmpeg.org/download.html. It looks like it creates the possibility to do the same on Linux, is that possible? And does someone have experience with this?

• Android and ffmpeg. Play video (with sound)

  18 février 2014, par bukka.wh

  I have compiled ffmpeg library add it to my project and now I want to play video (with full list of options - stop, pause, forward, backward etc). I have read roman10 ffmpeg tutorial. And I also find out tutorial which describes how play video with ffmpeg and SDL framework. The difference (if I have correctly understood) is that in roman's tutorial each frame of video turns into a Bitmap and is then passed to Java code where it shows on SurfaceView. And in the second tutorial, the video is playing with the help of the SDL framework without passing it back to Java code.

  I want to ask some questions:

  1. Which way is better: return Bitmap back to Java and show it on SurfaceView or play it with SDL?
  2. How can I play the sound of my video (can I do it with ffmpeg or do I need some additional libraries)?

• Resize videos in android

  18 février 2014, par Christopher Johnson

  I'm looking to resize videos captured using the MediaStore Intent after they have been saved to the SD card. I've done similar things with c# and ffmpeg and thought about using that with android but I've yet to be able to find a way to incorporate that into my eclipse running on my windows 7 machine.

  I'm a total *nix noob so all of the solutions that I've found for building ffmpeg into an android app are completely greek to me.

  Is there an alternative solution to ffmpeg that perhaps is already built into the android sdk for resizing videos?

  I'm just looking for the path of least resistance here...
