* make VideoStream class able to stream through ffmpeg again.
* formatted code
* using fixed quality instead of fixed bitrate to avoid artifacts in video; specially in beginning of video.
* ZoneMinder compiles with ffmpeg 0.5, 0.6, 0.7, 0.8, 1.0, 2.0
* Dont rescale pkt.pts&dts if it is AV_NOPTS_VALUE
* When using rtp format; if ffmpeg does not have a default codec, use CODEC_ID_MPEG4. (because this is what the default is as of 2.2 when this code was written)
