Updating to v3.4.6

Uses the ffmpeg's default hw frames parameters to ensure alignments and initial pool size
Adds VA support for more formats (Config.Decoder.AllowProfileMismatch)
Prevents renderer's disposal on every new video input but it will dispose it on Player.Stop or Dispose
Adds Ctrl+Q key binding for Player.Stop

Fixes an issue with the audio / video sync that it could happen on live streams with no buffer (0 duration)
Fixes critical issues with the Idle Renderer
Fixes a possible critical null reference on video processor that could cause issues with brightness
Fixes an issue with MP2 audio codecs (flat formats) and switches to MP3 when required
Fixes a proper fallback to sw format in case of hw failure
Fixes backwards compatibility with < Win8 (however XAudio seems to still have an issue)
Fixes an issue in case of initially audio fails to be able to continue play video

-		-= D3D11 Video Processor Support &amp; Media Renderer Improvements =-
+		Uses the ffmpeg's default hw frames parameters to ensure alignments and initial pool size
+		Adds VA support for more formats (Config.Decoder.AllowProfileMismatch)
+		Prevents renderer's disposal on every new video input but it will dispose it on Player.Stop or Dispose
+		Adds Ctrl+Q key binding for Player.Stop
 
-		Extends the current embedded video processor (FLVP pixel shaders) with the D3D11VP to support more filters, alternative color conversions, basic bob deinterlace and preparing others including HDR native.
-		Use Config.Video.VideoProcessor to choose which one to use. By default "Auto" is recommended to allow the library to switch when it requires.
-		* FLVP supports HDR to SDR, D3D11 does not
-		* FLVP supports Pan Move/Zoom, D3D11 does not
-		* D3D11 possible performs better with color conversion and filters, FLVP supports only brightness/contrast filters
-		* D3D11 supports deinterlace (bob)
-		* D3D11 currently performs only with video accelerated (hardware) frames
-
-		Adds Config.Video.Deinterlace to enable/disable deinterlace
-		Adds Config.Video.Filters to set filters (ensure that is actually available and supported by the VPs)
-		Adds Player.LastError to keep track of open/playback/buffering errors in the UI
-
-		Renderer: Code clean up and improvements
-		Renderer: TakeSnapshot now works more efficiently
-
-		Audio: Fixes a critical backwards compatibility issue with XAudio by updating Vortice libraries
-		Renderer: Possible brings back the broken backwards compatibility (Win7/Win8) from the previous 3.4.4 (not tested)
-		VideoDecoder: Fixes few performance issues with the new get_format / hardware frames allocation
-
-		Updates Vortice (you might need to update System.Runtime.CompilerServices.Unsafe to Version&gt;=6.0.0.0)
+		Fixes an issue with the audio / video sync that it could happen on live streams with no buffer (0 duration)
+		Fixes critical issues with the Idle Renderer
+		Fixes a possible critical null reference on video processor that could cause issues with brightness
+		Fixes an issue with MP2 audio codecs (flat formats) and switches to MP3 when required
+		Fixes a proper fallback to sw format in case of hw failure
+		Fixes backwards compatibility with &lt; Win8 (however XAudio seems to still have an issue)
+		Fixes an issue in case of initially audio fails to be able to continue play video
