That one doesn't use the hardware codecs though :)<br>
<br>
<br>
Not sure what else I could do here without actual access to the device.<br>
You would need to check why exactly it fails to call the Java method,<br>
and also debug why the color format that is used by the decoder does not<br>
match what we assume in the androidmedia plugin... and try to reverse<br>
engineer how it is supposed to be used.<br>
