  • Decode h264 video with csharp

    28 août 2011, par john bowring

    I am looking for a way to decode h264 (or indeed any video format) using c#. The ultimate goal is to be able to decode the images and very strictly control the playback in real time. The project I am working on is a non-linear video art piece where the HD footage is required to loop and edit itself on the fly, playing back certain frame ranges and then jumping to the next randomly selected frame range seamlessly.

    I have created an app which reads image files (jpegs) in from the disk and plays them on screen in order, I have total control over which frame is laoded and when it is displayed but at full HD res it takes slightly longer than I want to load the images from hard drive (which are about 500k each), I am thinking that using a compressed video format would be smaller and therefore faster to read and decode into a particular frame however I cannot find any readily avaiable way to do this.

    Are there any libraries which can do this ? i.e. extract an arbitrary frame from a video file and serve it to my app in less time than it takes to show the frame (running at 25fps), I have looked into the vlc libraries and wrappers for ffmpeg but I don't know which would be better or if there would be another even better option. Also I dont know which codec would be the best choice as some are keyframe based making arbitrary frame extraction probably very difficult.

    Any advice welcome, thanks

  • how to create or extract a silent mp3 from a video file using ffmpeg or mencoder ? [migrated]

    25 octobre 2011, par mirswith

    I am looking to create an mp3 of silence that is the same duration as the input video file using either ffmpeg or mencoder.

    Using ffmpeg I have tried this :

    ffmpeg -y -i in.avi -ab 8k -ac 1 -vol 0 -acodec libmp3lame out.mp3

    Which works great if the video has an audio track but fails miserably if it does not.

    Any ideas ?

    Thanks !

  • .NET FFmpeg wrapper for video playback [closed]

    12 février 2015, par SharpAffair

    Looking for an FFmpeg wrapper usable in .NET. The wrapper must support video playback with audio.

    The following projects are incomplete FFmpeg wrappers :

    http://code.google.com/p/ffmpeg-sharp/

    http://sourceforge.net/projects/sharpffmpeg/

    http://sourceforge.net/projects/ffqlay/

    http://www.ffmpeg-csharp.com/

    http://www.intuitive.sk/fflib/post/fflib-net-released.aspx

    ffmpeg-sharp is the closest thing I’ve found, but it’s also incomplete (no audio in video playback).

    I’m quite sure that stable proprietary wrappers do exist, so I will award the bounty to anyone willing to share the code or able to find a complete third-party version.
