hi folks,
thanks a stack. here is an update on my attemots to efficiently get the
actual color pixel values from the DSequence during the dataproc
i first tried the offscreen image buffer but found that this contained
2yuv compressed data
i then tried to get the uncompressed data as a Pixmap from the screen
buffer of the DSewuence.getScreenBuffer()
but this throws the exception
quicktime.std.StdQTException[QTJava:6.1.3b1],-50=paramErr,QT.vers:
7038000

this means that i will try next to get the pixels from the target port
of the DSequence - which is the main frame of the app and has several
other visual elementes aside from the QRCanvas.
any help or code snippets for getting the pixels from the DSequence
directly would be greatly welcome,
stay well, gobble gobble ...
