Probably not. That error is coming from FFmpeg itself. We don't control the error messages in their source. Some if them are meaningless, or actually just warnings flagged as errors. If the video plays then it's probably fine. Could just be an error because an abrupt start in the stream. (Typical of shows recorded on DVRs)
