The VideoLAN Forums

I am interested in finding out if VLC can be used to record H.264 encoded data streamed by one of our Lumenera IP cameras.

Regardless of the encapsulation and transcoding options, we always run into the same warning message:
main warning: trying to send non-dated packet to stream output!

I'm wondering what the next step should be.

Thanks,
James

hi mihaychuk,
You can take rtsp stream from camera and transcode it to h264 by changing the vcodec.
