  • Is there any safer way to include FFMpeg in commercial applications ?

    17 février 2017, par Ayyappa

    https://www.ffmpeg.org/legal.html

    The above page doesn't make any thing clear if we can use the libraries in commercial projects or not.

    Incase if there are algorithms breaking patents, which formats I shouldn't support to avoid risk?

    In short, Which way its safer to add ffmpeg to create a multi media app for iOS and Android (and may be later to desktop too).

  • Recorded video from iPhone rotated 180 degrees on FB, Vimeo, Youtube

    17 février 2017, par Junho

    it's my first question.

    My question is this. I developed some app and the app records a video.

    The problem is that the recorded video on iPhone looks rotated 180 degrees in FB, Vimeo, Youtube after sharing it. But it appears normally on iMessage, Instagram. I'm using FFmpeg while recording it.

    Could you let me know the cause of the problem and the solution on the code?

  • Argument error while encoding video in rails

    17 février 2017, par CR7

    I am trying to upload video and convert it into mp4. For conversion I am using the gem carrierwave-video. My configuration as same in the question

    I have installed ffmpeg in my system. But when I upload video the following error occurs.

    VideoFailed to transcode with FFmpeg. Check ffmpeg install and verify video is not corrupt or cut short. Original error: ArgumentError

    When I comment the line

     process encode_video: [:mp4]

    in VideoUploader. It works fine, but conversion is not happening. Is there any issue in passing parameters. Please give your valuable answers
