[gst-embedded] Question on gst_plugin alsasink

[Shenhong Wang]

Brad,
thanks! 
At the moment I didn't put any timestamp on the frames(buffer) yet.
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 drop all frames(packets) from the break. Why? How to fix it? Thanks!
 
Best Regards!
Shenhong WANG

Hi, your issue seems that audio frame is delayed when arrivering alsasink.
 
basesink will drop the delayed buffer and you could'nt hear any sound.
 
Please check your timestamp of buffer.
 
Brad

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!
