How do you get infos about a DVD stream? like, dvd, current, display, examine

andy

when you got a retail dvd, how can you get info abouot its stream, like knowing what's the bitrate for audio and video, the dimensions, ect...??

My standalone Sony has a menu to display the current audio stream attributes.  But it doesn't list everything.

Another method: open your DVD in PgcEdit.  Ignore the warning messages 'cannot create backup' and 'encrypted VOBs'.  Then, right-click on a PGC in the domain you want to examine, and choose 'Domain Streams Attributes'.

But how can you get to the bitrate, both for the audio and the video??? Iquot;m sure there's some soft out there that can tell you that...

I use Bitrate Viewer 1.4 to read the video bitrate of a DVD.  For the audio, I just play the DVD in PowerDVD and look at the audio bitrate (show information).

Hello, I've been thought it shows the video bitrate before, too.
But it shows the bitrate of video and all others(audio, subtitle). The graph is plotted according to the data of VTS_TMAPTI of IFO by calculating sectors per second, and the value of sectors involves video and all others.
When I rewrote the value of this IFO, the graph changed as it.
(Sorry if it is known.)

DVDShrink shows duration time and each stream size about each title, so I think possible to know roughly each bitrate by calculating size per time. (But impossible when size is small.)

VobBlanker shows the audio bitrate, usually CBR, read from the VOBs. But be careful, not always the audio bitrate is constant in a DVD. In this case VB will show the bitrate of the first frames and the estimated size will be wrong.

Hello!
This isn't probably the most convenient method to find out the actual video bitrate, but when you demux the DVD video stream and then open it in VirtualDubMod, in file info you can find the average bitrate of the stream and to my knowledge it's quite accurate. With a bit of calculations you can also compute the min and max bitrate according to that stream info. And you don't have to demux the video - you can open the VOBs directly from a DVD and then calculate an average value from the reported bitrates. Another useful tool is PVAStrumento, which can scan VOBs and give you the min/avg/max bitrate of the video, but it does not work for every stream...
