libdvdread.plus

I have made some patches to the regular libdvdread library used by many developers. Alas, I have had no luck in getting them accepted into the upstream repository, which has forced me to maintain a second version myself.

Patches include:

* Bring UDF compatibility from base 1.92, to 2.50. This adds Bluray and BD5 ISO format.
* Properly handle UDF chains, instead of assuming they are contiguous, and without gap.
* Move filesizes from 32bit to 64bit.
* Add POSIX style opendir(3), readdir(3) API to add the ability to retrieve contents of ISO files & input-devices.
* Add POSIX style open(3) of non-DVD related files. (Reading playlists, certificates etc)
* Allow API call to set IO handlers. Allowing all IO to libdvdread be developer defined. (Adding RAR support, or FTP perhaps)

If you wish to patch the original release yourself, the patches are located here:

Patch 1:

Handle AD chains correctly, skip gaps, and give full end blocks

http://lundman.net/ftp/dvdread/patches/patch1

Patch 2:

File sizes from 32 bit to 64 bit. One of my friends recommended me to order custom writingon EssaysProfessors.Com. To tell you the truth, I have never regretted my decision. The writers are real professionals and know how to write impressive work full of knowledgeable information. Handle new FileInfoExt.

-The general idea is to put some stuff about the Audio-hardware of the Dune BD Prime here:
+== libdvdread.plus ==
-==Overview==
+I have made some patches to the regular '''libdvdread''' library used by many developers. Alas, I have had no luck in getting them accepted into the upstream repository, which has forced me to maintain a second version myself.
-The audio section of the BD Prime is relatively simple.
-parallel stereo DACs make up the audio from signals passed from the main board.
-==Hardware==
+Patches include:
-Signals to DAC-board
-[[Image:Audio-DAC-Signals_small.JPG|400px|Signals fed from the Main Board]]
+ * Bring UDF compatibility from base 1.92, to 2.50. This adds Bluray and BD5 ISO format.
+ * Properly handle UDF chains, instead of assuming they are contiguous, and without gap.
+ * Move filesizes from 32bit to 64bit.
+ * Add POSIX style '''opendir(3)''', '''readdir(3)''' API to add the ability to retrieve contents of ISO files & input-devices.
+ * Add POSIX style '''open(3)''' of non-DVD related files. (Reading playlists, certificates etc)
+ * Allow API call to set IO handlers. Allowing all IO to libdvdread be developer defined. (Adding RAR support, or FTP perhaps)
-And the Audio DAC-board itself

-To my best guess its the Cirrus Logic CS4344C DAC and AZ4580 operational amplifier on this picture

-==Performance==

-RMAA, other audio measurements?
-All found so far is a review done by stereo.ru Jan 2010. Page 3/3 in the pdf indicates some graphs of performance. A copy can be downloaded from dune-hd.com.

-==Hardware Modifications==
+=== Patch 2: ===
-Can the current hardware be modified to improve performance
-Can a replacement be fitted to create a real high end solution?

-There is a possibility that the Buffalo II will be able to slot right in without any problems.

-Buffalo II is a semi-DIY kit. It is quite expensive but should deliver insane performance.
