Hello,
I am developing an application where i need to convert my webcam video in to H264 format. I am using Windows XP and FFMPEG. The offline file conversion is working fine with me using FFMPEG. But its not working for live videos . Can you tell how i can capture Webcam live video using FFMPEG ? I heard some patches are available for capturing VFW devices but not sure how to configure it. Please help me. Thanks, Vivek. _______________________________________________ ffmpeg-user mailing list [hidden email] https://lists.mplayerhq.hu/mailman/listinfo/ffmpeg-user |

This patch is probably outdated, you will need to understand it precisely and apply it to current svn trunk. I think you cannot simply patch the lastest ffmpeg svn and then compile it "out of the box"... good luck, yohann _______________________________________________ ffmpeg-user mailing list [hidden email] https://lists.mplayerhq.hu/mailman/listinfo/ffmpeg-user |

By running: ffmpeg -f vfwcap -i 0 output.mpg you should be able to record from the default device. You might have to pass the framerate before the -i, such as: ffmpeg -f vfwcap -r 25 -i 0 output.mpg Ramiro Polla _______________________________________________ ffmpeg-user mailing list [hidden email] https://lists.mplayerhq.hu/mailman/listinfo/ffmpeg-user |

Its working fine great. But i have a doubt. The MP4 file i encoded with is
not playing back in flash player . I dont know whether the input command to FFMPEG makes a difference. The command i gave was *"C:\Program Files\ffmpeg\ffmpeg.exe" -f vfwcap -r 15 -i 0 -vcodec x264 -deinterlace -b 65000 "C:\Program Files\ffmpeg\live.mp4"* the resulting mp4 file is not playing in flash player. Can u suggest me a good way of doing it?? That will help me a lot since i am not an expert in FFMPEG field. Thanks, Vivek.
