• AVCodecContext settings for H264 (1080i)

  23 septembre 2013, par moose

  I'm trying to configure x264 for 1080i capturing. Most of these settings below are found in different examples. However, compiled together they don't work. ffmpeg API reports no error, but avcodec_encode_video() always returns zero.

  Some of the numbers are strange to me... for example, gop_size. Isn't 250 too high ?

  Event you can't offer the final answer, I'm still interested in any kind of comment on this subject.

• audio extracted from flv file via ffmpeg is of shorter duration than the actual flv video [closed]

  11 janvier 2013, par user1961143

  I have extracted audio from flv file via ffmpeg using this command :-

  ffmpeg -i 164_29.flv v19.mp3

  The flv videos duration is 3 minutes but the audio is of 2 mins 20 seconds only. On searching i found that the silent pieces of audio are removed when generating audio from ffmpeg. But i need the audio file to be of exactly same duration as flv video as later i need to put this audio in the flv video itself. Please help as this is urgent for our project. I am running the FFMpeg via .net windows service, so in case you know any other tool which can extract the audio of same duration as video and can be run via .net, it would be useful too.

  If you see the duration of video is of 3:04 but audio extracted from it is of 2:25 only.
  Actually i am using ffmpeg overlay to show two videos side by side in our debate project for the client. Now ffmpeg takes audio from first video by default. But we want the audio from both videos together as a debate going on. Hence I thought of a solution to extract audio from both videos and merge them and than apply them to the overlayed video. This will all work perfectly only if I get the complete audio from the video file i.e. of equal duration.
  For more information i am writing here the overlay command we are using :-

   **ffmpeg -i 164_29.flv  -vf "[in] scale=359:320, pad=2*iw+6:ih
  
    [left];    movie=164_30.flv, scale=359:320 [right]; [left][right] 
  
    overlay=365:0  [out]" -b:v 3600k -y a1.flv**
  
  
  
   **This is the console output of this overlay command:-**

  C :\Users\ritika.thakur>ffmpeg -i 164_29.flv -vf "[in] scale=359:320, pad=2*iw+6
  :ih [left] ; movie=164_30.flv, scale=359:320 [right] ; [left][right] overlay=365:0
  [out]" -b:v 3600k -y a1.flv

  Everything is working fine except that we want audio from both videos playing together in final overlayed file. I would be highly grateful if you can help in this and let me know if its possible to do via ffmpeg or not.
