Hi.

Enable capturing of raw 32bit IEC958_SUBFRAME.

The 24-bits PCM data can be obtained using iec958 plugin.

Known problem: captured stream may begin with either left or right subframe. Since the iec958 plugin doesn't decode preamble it may swap the channels sometime.

Regards, Tim.

Applied this one, too. (Do you happen to have a fix for iec958 plugin, too? :)

Not yet. I'm in doubt about a clean way to drop one subframe from the raw stream. Could you give me a hint?

It'll be tricky, yes. We can prepend a zero in the first shot and keep one pending channel data to shift. For example,

raw: R0 L0 R1 L1 R2 L2 ... R(n-1) L(n-1) | R(n) L(n) ... dec: 0 R0 L0 R1 L1 R2 ... L(n-2) R(n-1) | L(n-1) R(n) ...
