(This commit also modifies the obs-outputs module) The first video packet video offset (the value used to set the starting point of video data) would be set to the DTS value of the first video packet. However, when b-frames are used, the first DTS value will be negative. This was originally done because FLV muxing requires that the first packet's DTS start from 0. Unfortunately, this would also effectively cause the first packet's PTS/DTS value to be shifted forward by the negative amount, which would cause video sync to be off by a video frame or two. This fixes it to start at the PTS value instead and preserve any negative offsets. Additionally, the FLV muxing code has been fixed to ensure that it adjusts the starting video DTS to 0, and now correctly adjusts the first audio packet's timestamp according to that DTS as well (which it didn't do before).
