thanks! <BR>
At the moment I didn't put any timestamp on the frames(buffer) yet.<BR>
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!<BR>

<DIV></DIV><BR>Dear all,<BR>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. <BR>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. <BR>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!<BR> <BR>Best Regards!<BR>Shenhong WANG<BR><BR>
