• .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.

• mencoder -> x264 : FPS problem : Video is 2x faster at the output

  28 mars 2011, par Julien Palard

  I got an input video, ffmpeg says about it : 29.96FPS 59.75 tbr 1k tbn 59.83 tbc
  My process to encode is :

  $ mencoder input_video -vf dsize=480:320:0,scale=0:0,expand=480:320,dsize=1.5,format=i420 -of rawvideo -ofps 25 -ovc raw -nosound -o output.yuv
  
  $ x264 input_video --profile baseline --fps 25 [blahblah] -o output
  
  $ MP4Box -add output.yuv -fps 25 output.mp4

  Im'simplificating a lot here to let you parse less as I'm encoding the audio apart and merging the result using mp4box.

  ffmpeg -i output says that the vid is : 25 FPS 25 tbr 25 tbn 50 tbc

  And while playing the video, the audio is normal, the video is 2x faster than input, so the video ends at the half of the audio track (compared to the input, the audio is good, it's just the video running 2x faster)

  Any idea about my problem ?
