Hi,
I have another alternative, if I configure my original audiosink as audio
decoder.
This audio decoder element also has srcpad, but actually no data is through
the srcpad to downstream elements, the data goes down to HW audiodevice in
it, and it also provides clock.
when I use playbin, I set fakesink as audio-sink, so can playbin still
work except some functions disabled (such as volume) ?
BRs.
