Hi
I am facing few problems using the dshowdecwrapper's elements dshowadec_mp3 and wma Here is the pipeline commandline: gst-launch filesrc location=c:\\mellow.wma ! dshowadec_wma4 ! audioconvert ! directsoundsink
Is the right way to construct the pipeline? It always hangs at pre-rolling. Debugging it I found it's not calling gst_dshowaudiodec_sink_setcaps function and calling directly gst_dshowaudiodec_chain, not sure it is correct or not.
I have attached the zip file with the error log at debug level 5. Can you please let me know if there is something with the element or pipeline construction etc. Error log is also here: http://dl.dropbox.com/u/418325/error.zip

You will need asfdemux in there; WMA files are ASF containing WMA.
Then the decoder you need to use will depend on exactly what codec is used in your file. If you use decodebin2, this will all be done for you automatically.

Hi
Decodebin2 is picking up ffmpeg codec which is not what I want, Adding asfdemux is not working either, in the following pipeline this works ok: gst-launch -ev --gst-plugin-spew filesrc location=c:\\Heavy.wma ! asfdemux ! ffdec_wmav2 ! autoaudiosink
but this doesn't work: gst-launch -ev --gst-plugin-spew filesrc location=c:\\Heavy.wma ! asfdemux ! dshowadec_wma4 ! autoaudiosink I think the problem is with dshowadec_wma4, and dshowadec_mp3 playback also doesn't work. I tried debugging the issue but not being familiar with the code it could take a while.
Can anybody help me point out the issue with dshowdecwrapper or provide me directshow filter related debugging tips to root out this issue? Srinivas Date: Tue, 6 Sep 2011 16:26:00 -0700

If ffdec_wmav2 works, then the file obviously contains WMAv2 audio. But then you try to use the WMA Lossless decoder from dshowdecwrapper - and that obviously doesn't work. Use the right decoder and it should work fine.

I have some more information on this, when I remove the registry bin file then I don't receive the error filesrc0 (see FIRST LOG below) and it starts playing the mp3 file, I didn't have much success with wma files.
And when the registry is removed it starts to play look at the SECOND LOG. I am guessing there is some timing issue from the first push and when decoder is ready causing the erratic behaviour, which probably eliminated when all the plugins are being iterated for registry creation.
Is there a way we can skip the registry creation, is it only a compile time option? Windows builds (http://code.google.com/p/ossbuild/) are probably a bit older is there a fix in the later releases for any registry related bug?

The registry is always required - even on the first run, it gets
created and then used. You may be right that there's a race condition of some sort; you'll need to debug that. However, be warned: the dshow mp3 decoder does not work very well with real-world mp3 files, it'll frequently error out. This is not a problem with the gstreamer wrapper, it's a problem with the underlying dshow element. On windows, you can instead use the acmmp3dec element. The WMA problem remains simply that you're using a decoder for a different format from what your file actually contains.

Hi
BTW I tried v2.0 of wma which is causing the same issue.
Can you let me know where is latest acmmp3dec plugin available?
Thank you very much for your help so far!
