Hi, Zhao Liang:
Generally, the aacdec &alsasink will not play out any audio frames(packets)
after its source element has a break to send audio frames (packets) to them. It
looks the alsasink drops all frames(packets) from the break. The break is
needed because we have more video frames and sometime the wireless signal is
not good.
It looks the aacdec is slower than the expectation from alsasink.If so, how to
fix the issue? thanks!
best Regards!
Shenhong

Hi Shenhong,
Your issue is very similar with the issue I even met. I think it is due to
gstbaseaudiosink/gstaudiosink, it will drop the packets by gstringbuffer when
read rate is bigger than write rate in ringbuffer, please see gstringbuffer.c
gst_ring_buffer_commit_full ().
For the rootcause, I think maybe the alsasink audiodevice buffer is too big or
your aac decoder is too slow.

Question on gst_plugin alsasink
Dear all,Now we are using alsasink to play audio on Marvell PXA310 board. The
audio is aac format. The audio frames(packets) are frequently sent to the aac
decoder & alsasink to play out. Unfortunately only the begining frames can be
played out and then nothing is played out. If we save those audio frames into a
file, the aac decoder&alsasink can be successfully played out. It means the
audio frames are ok. Could anyone tell me what's the difference for alsasink to
process audio packets and files? How to fix the above issue? thank you very
much! Best Regards!Shenhong WANG
