Description:
The BDInfo tool was designed to collect video and audio technical specifications
from Blu-ray movie discs, including:
- Disc Size
- Playlist Contents
- Video Stream Details
- Audio Stream Details
- Subtitle Stream Details
- Graphics Stream Details
Requirements:
Known Issues:
- BDInfo will *NOT* function correctly with copy-protected discs.
- Inaccurate bit-depth on Dolby TrueHD audio streams.
- Inaccurate channel layout, sample rate and bit-depth on DTS-HD streams.

Instructions:
Click the Browse button and select the BD-ROM drive letter of your Blu-ray
disc or mounted .ISO image. You may also select a folder containing a Blu-ray disc
layout.
After a moment, the available .MPLS playlist files will be listed in the Select Playlist(s)
window along with the playlist length in hours, minutes, and seconds as well as
the combined size in bytes of all the individual files referenced by the playlist.
By default, the playlists are shown in order of length with the longest playlists
at the top. In most cases, the topmost playlist will correspond to the main title
feature of the disc. However, if there is more than one version of the main title
on the disc (ex. separate Theatrical and Unrated cuts of a movie) or additional
features such as long-running documentaries, then you may need to lookup the advertised
lengths of the titles to determine which playlists you are interested in.
Clicking on different playlists will change the listed Playlist Files and
Playlist Streams. Each constituent playlist file also has its length and
size displayed while the streams in each file will have their codec, language, bitrate
and other pertinent information shown in the description. It is worth noting that
examing the stream information for a playlist is another useful way of determining
which playlists you are interested in.
Many streams will not have a bitrate displayed - this is because the actual bitrates
for these streams cannot be determined without a more thorough scan of the playlist
files. A full bitrate scan is performed by clicking the Scan Bitrates button.
This operation can take a considerable amount of time! You can reduce the processing
time somewhat by placing a checkmark next to only those playlists that you want
to have scanned.
Finally, you can save the results of the initial playlist scan and full bitrate
scan by clicking on the View Report button. From the report screen, click
the Copy to Clipboard to copy the report and then paste it into your favorite
text editor, word processor or email program.
Version History:
2008-07-01: Version 0.3.1
- Fixed bug in initial disc scan that occasionally prevented correct display of audio header information (i.e. channel count, sampling rate).
- Fixed bug that caused BD+ and BD-Java to be mistakenly flagged on the next disc when performing multiple scans in a row.
2008-06-30: Version 0.3.0
- Fixed bug in processing of playlist files that prevented Profile 1.1 Bonus View video
tracks and some audio/subtitle tracks from being displayed.
- Added detection of DTS-HD Master Audio 96kHz sampling rates, but 7.1 channel counts are still not detected.
- Added chapter marker list to output report.
- Some minor performance improvements to the initial disc scan.
2008-06-28: Version 0.2.3
- Fixed overestimation of TrueHD and DTS-HD variable audio bitrates.
- TrueHD core track bitrate is now subtracted from the reported TrueHD bitrate.
- Added BD+ and BD-Java detection to report.
- Added stream diagnostics option to report to show stream byte and packet counts.
- Fixed bug with cancel followed by a rescan of the same playlist.
2008-05-30: Version 0.2.2
- Fixed another bug in processing of certain playlist files.
- Fixed bug in detection of Dolby TrueHD audio channel layout.
2008-05-21: Version 0.2.1
- Fixed bug in processing of certain playlist files that contain multi-angle information.
2008-05-12: Version 0.2.0
- Changed language display to show name of language rather than ISO 639-2 three-character
language code.
- Changed estimation of Dolby TrueHD audio bit depth to be more accurate (although
still a guess).
- Changed forum report audio bitrate for multi-file playlists to reflect averaged
bitrate across all playlist files.
- Changed time in / time out file display in report to reflect playlist relative times
rather than file relative times.
- Fixed bug in processing of certain playlist files that contain multi-angle information.
- Added playlist filter to remove assumed "garbage" playlists from display.
