Error using dshwodecwrapper

[Srinivas Sakhamuri]

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?

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.
