• Options for cross-platform video & audio playback with speed control [on hold]

  11 janvier 2016, par Jon Cook

  I’m looking for a component that will do the following :

  1. (Must) Playback most common video formats (e.g. mp4, wmv, AVCHD, F4V, swf, MKV, DIVX, Mov, Avi, MPEG-1, MPEG-2, flv, VOB, asf)
  2. (Should) Stream video
  3. (Must) Playback most common audio formats (e.g .mp3, wav, .m4a, .mid)
  4. (Should) Stream audio
  5. (Must) Slow-down/speed up video&audio
  6. (Must) Adjust pitch of video&audio
  7. (Should) Zoom in on video

  It needs to work on the following platforms :

  1. (Must) Mac
  2. (Must) iPad
  3. (Should) iPhone
  4. (Should) Android
  5. (Should) Windows

  I’m prepared to work with any language, tech stack, whatever, as long as it meets those requirements.

  Is there any such thing out there ?

  I’ve started looking around (have checked out http://ffmpeg.org/ and www.vitamio.org/) but I’m a bit overwhelmed - too many variables - hoping someone out there might have some hints ?

• Mobile Camera live audio/video streaming and encoding

  7 juin 2015, par Strikecounter2

  I know this question has been asked a couple of times, but I still haven’t found the right answer for my question.

  I would like to code an app that is able to live-stream audio and video while the content is being recorded and then uploaded to a server. I’d prefer to have my own back-end using Parse, because I want a high scalability. I know that the video has to be encoded to a h.264 codec and the audio to an AAC codec, but I don’t know how to achieve this. I have heard of the FFmpeg framework, but I am not sure if I would violate their license if I distribute my app or even sell it to somebody else.
  I would then like to receive the stream from the server to open it on the iPhone/android phone.

  They key requirements would be :

  • Low Latency
  • About 24 fps
  • Audio/Video in sync
  • No buffering while watching

  I would like to use Swift as a programming language, but if there is no way to use a swift-wrapper for any frameworks I would focus on Objective-C too.

  I am willing to learn everything that is needed, but I don’t know where to start.

• Android video saves as type "file" instead of video format

  25 novembre 2015, par Marc Rasmussen

  So I have a website where I allow people to upload a video from their phone and send it to their friends.

  Now Iphone works well because it is usually an .mov file. However when I attempt on my android (Samsung galaxy) I get FileType : file

  Howere is an image from my filezilla as to what has been uploaded :

  

  The highlighted are the files uploaded from the android device.

  Can anyone tell me why this is happening ? and how I can make sure that it is a video ? and/or convert it into a mp4 format.
