[Approved] Patch for load External Audio Track (1 Viewer)

[Sebastiii]

Hi,

This is the path that permit to load external audio track (DTS, MKA, MP3 and AC3) in graphbuilder that partial match of movie.

For example :
movie.mkv with movie.ac3 but it can be load movie.english.ac3

To make it work we must need use of Mediaportal StreamSwitcher (patched too for correct audio pdwgroup) and best to work with MPC Matroska Splitter.

Cheers,
Seb.

Hi,

I have tested and the code (// No stream info from splitter) break the name of audio and trackname on internal audio when splitter is not IAMStreamselect.

So i recommend to comment out this part from Audio Language and Audio Type.

Thanks effectively your code is really more clear congrats

Edit :

We have a issue, i try to explain.
If we use a splitter that didn't use IAMStreamSelect (ie MPC Matroska) all stream are output in single so we must use FFDshow Audio with streamswitcher or Mediaportal Audio Switcher.
If we use ffdshow it doesn't work good even if Mediaportal Audio is in graphe, i think we must avoid it (it's not the good idea) the best setup is to use it but without stream switcher enable.
So if we use Mediaportal audio switcher all the time, it breaks 5.1 for WMA Audio.
I have fix it by added : DirectShowUtil.AddFilterToGraph(graphBuilder, "ffdshow Audio Decoder"); see below

//Set High Resolution Output > 2 channels
IBaseFilter baseFilter = null;
graphBuilder.FindFilterByName("WMAudio Decoder DMO", out baseFilter);
if (baseFilter != null && wmvAudio != false) //Also check configuration option enabled
{
//Set the filter setting to enable more than 2 audio channels
const string g_wszWMACHiResOutput = "_HIRESOUTPUT";
object val = true;
IPropertyBag propBag = (IPropertyBag)baseFilter;
hr = propBag.Write(g_wszWMACHiResOutput, ref val);
if (hr != 0)
{
Log.Info("VideoPlayerVMR9: Unable to turn WMAudio multichannel on. Reason: {0}", hr);
}
else
{
Log.Info("VideoPlayerVMR9: WMAudio Decoder now set for > 2 audio channels");
}
DirectShowUtil.AddFilterToGraph(graphBuilder, "ffdshow Audio Decoder"); //Here for fix WMAPRO with audio switcher MP
DirectShowUtil.ReleaseComObject(baseFilter); baseFilter = null;
}

Hi,
IT is strange but LAV Splitter is the worst for using with external tracks.
I saw not only ghost audio track but also freezes and shuttering.

Hi,

Effectively, with LAV (IAMStreamSelect Interface) it doesn't work well, sorry so i have see your pm and didn't answer yet.
I will try to look again but with IAMStream Source Splitter is quite not easy, and i don't know how to do that right now, the best use is Matroska, it would be good to know if mpc-hc works ok with LAV Splitter too.
Thanks.
