Can't decode Windows Media v9 audio (WMA3)
Last modified: 2008-06-27 09:08:01 UTC
Please describe the problem: GStreamer doesn't seem to be able to decode Windows Media v9 audio. It gives the error: ** Message: don't know how to handle audio/x-wma, wmaversion=(int)3, bitrate=(int)384000, depth=(int)24, rate=(int)96000, channels=(int)2, block_align=(int)8192, codec_data=(buffer)1800030000000000000000000000e0000000 I can play the same file (both audio & video) with mplayer, so I think that means ffmpeg is able to decode it, and gstreamer should be able to decode it. Also, it looks like ffdec_wmav2 sets it's sink pad template's caps such that it only accepts wmaversion: 2, even though the description says it handles Windows Media Audio v8/9 (Windows Media 9 audio has wmaversion: 3). Steps to reproduce: 1. Download http://owenfam.org/test.wmv (note that this is the first 1MB of the file) 2. gst-launch playbin uri=file://test.wmv 3. Actual results: playbin plays the video correctly, but gives the following error for audio:** Message: don't know how to handle audio/x-wma, wmaversion=(int)3, bitrate=(int)384000, depth=(int)24, rate=(int)96000, channels=(int)2, block_align=(int)8192, codec_data=(buffer)1800030000000000000000000000e0000000 Expected results: should play both audio and video Does this happen every time? yes Other information: I'm using Ubuntu Hardy, 32-bit on an x86 platform.
The reason you can play this file with mplayer is because it's using the win32 .dll . There's no open-source WMA3 decoder. IIRC, the pitfdll plugins can wrap that decoder, which might be available for your distribution. Else there's also the fluendo (commercial) decoders. Closing this bug since there's alternatives.
