Subject: [EXTERNAL] [FFmpeg-user] Frame Drops and Audio Sync Issues
I captured some video from a hardware capture card. It has a few hundred frame drops in one hour of video. The container format is .avi. When I play the captured file with mplayer, the audio is out of sync with the video
I might offer - The core reason for the captured video to be out of sync and to have dropped frames might be disk IO.
Try a recapture with a raided for speed drive set.
This is more likely if what you are capturing is uncompressed and less likely if what you are capturing is highly ( low datarate) compressed.
