Incorrect "Left Eye" reporting on non-3D BDs with multiple video streams #26

Closed d4rkne55 closed 3 years ago

d4rkne55 commented 3 years ago

I came across the issue now, that BDInfo outputs "Left Eye" on the video streams of my Transformers BD. I was first thinking that the video stream is just one side of a 3D source, still with some flag that BDInfo reads out, but I couldn't find anything 3D for the first Transformers movie from 2007.

Checking the following commit explains why: 5263eb6ff871c876ab3f0a00b645cec800756a60

The video stream is a regular AVC encode, not 3D, and the playlist doesn't have this BaseView flag, but the playlist contains two video streams (the second one hidden, but doesn't matter for this). Probably this is just a stream for PiP?

VIDEO:

Codec                   Bitrate             Description     
-----                   -------             -----------     
MPEG-4 AVC Video        31414 kbps          Left Eye / 1080p / 23.976 fps / 16:9 / High Profile 4.1
* MPEG-4 AVC Video      690 kbps            Left Eye / 480p / 23.976 fps / 16:9 / High Profile 3.2

It sets the BaseView info to false then. And that BaseView property decides then whether it's the left or right eye stream in the output, if it's set.

Ah, didn't catch the is3D property. And that was quick.^^
