Release Notes
AVBlocks SDK for .NET Release Notes

-----------------------
OS / CLR Requirements
-----------------------

* AVBlocks.clr4 - Windows 7 SP1 and above / CLR4 (.NET Framework 4.0/4.5.2/4.6.2)

--------------------------
Redistributable Components
--------------------------

Windows
-------
* AVBlocks.dll
* AVBlocks.clr4.x86.dll

* AVBlocks64.dll
* AVBlocks.clr4.x64.dll

------------
Dependencies
------------
AVBlocks.NET does not depend on any C/C++ runtime library.
However it uses AVBlocks SDK for C++: either AVBlocks.dll (x86) or AVBlocks64.dll (x64).

-------------------
Runtime Requirments
-------------------

* wmvcore.dll

`wmvcore.dll` is loaded dynamically by AVBlocks and is used for ASF muxing and demuxing (Windows Media).

NOTE:
`wmvcore.dll` is not present by default on Windows "N" versions, or on Windows versions without Windows Media Player

`wmvcore.dll` is not installed by default on Windows Server 2012, 2012 R2 by default. On those systems you will need to install
the "Media Foundation" or "Desktop Experience" feature from Server Manager.

* msdmo.dll

This library is loaded dynamically by AVBlocks and is used for the Windows Media codecs (WMA/WMV).

-----------------
Demo Restrictions
-----------------

The following restrictions exist when operating in demo mode:

* If a video stream is processed a demo logo is overlaid in each video frame.
* If an audio stream is processed a short demo sample is mixed with the original track at random places.

New
---

* AVBlocks can read/write Ogg(Vorbis).
* AVBlocks can write Windows Media Audio (Windows only).
* The transcoder can encode images to video (for producing DVD-Video compatible videos with a single frame).
* Metadata support. The transcoder can read/write metadata for certain formats (Wav, Mp3, Ogg/Vorbis, Window Media). The MediaInfo class can read metadata.
* The transcoder can seek in the input. (for compressed audio the seeking is not precise per pcm sample)
* The transcoder can read output in descrete steps (Transcoder::read). Convenient when uncompressed audio or video is required.
* The transcoder can be used by specifying only input and output filenames (minimum settings).
* Existing samples ported to Mac OS X and Linux (Ubuntu).
* MediaInfo sample extended to show existing metadata (pictures are saved to files).
* AVB-22: The frame rate filter can be explicitly set in order to compensate for missing video frames.

Fixed
-----

* AVB-4: Mp3 length is reported as zero.
* AVB-5: Inconsistent collections API.
* AVB-8: The MediaSample::endTime property is used for two different purposes.
* AVB-13: Allow AVB to be loaded and used more than once in a single process.
* AVB-14: Wav file duration is reported in milliseconds while it should be in seconds.
* AVB-16: The transcoded file is shorter than the source file.
* AVB-21: A/V sync issues in MPEG-PS.
* AVB-30: MPEG2 Muxer generates corrupt output.
