WMA again
Marsdaddy:
Here is an update, as promised!
I submitted a version of "libwma" to the tracker on Saturday and it was suggested that rather than integrate straightaway into the rockbox codec architecture, I should write a plugin to test the decoder for accuracy and speed.
Well, I've now written a "wma2wav" plugin, which is working on my simulator build.
Next step is to try it on a real device (iRiver H340) to see if it's up to the job. Listening to the WAV output I think it's a little "rough", I need to do something a bit more scientific with the output.
When I have wma2wav working and have more faith in the decoder, I shall make a patch of it.
And that is the end of the news. ;D
saratoga:
Awesome news!
Assuming you can get your iRiver to record the PCM samples, you could compare the output to WMP. Do you have matlab? You could pretty easily use the wavread() command on your output and WMP's and then go sample by sample to see how close you are. I doubt you'll be sample exact since theres fp involved in the WMP decoder most likely, but assuming you're within a bit or two, I doubt anyone will mind :)
Edit: new = news
MU4L:
Great work Marsdaddy - look forward to the patch :D !!!
Mr. Brownstone:
Fantastic news! Keep up the good work, we all appreciate it! ;D
Marsdaddy:
Further update for those awaiting this!
I have completed the plugin WMA decoder and have been banging my head against the wall for the last few days because although the code compiles and runs fine in the uisimulator, it won't compile for my platform, the iRiver H340. For the technically minded, it causes an internal compiler error "insn does not satisfy its constraints".
I have been attempting to come up with test code that exhibits the problem but of course it does not show when I isolate the code. I will continue to rework/reorder the code until I get it to generate correctly.
Wish me luck ???
