<div class="">And we sure the timestamp is correct and sync with “wall clock time”.</div>
<div class="">But, we still have some questions, need your help.</div>
<div class="">1. Now, H264+AAC is working well.</div>
<div class=""> After playing about 3 hours, audio is good but video will not very smooth to play.</div>
<div class=""> Do you have any suggestions?</div></div></div></blockquote><div><br class=""></div>Are you absolutely sure that your “fPresentationTime” values - for both audio and video - remain accurate even after 3 hours? (In particular, watch out for accumulated truncation errors.)</div><div><br class=""></div><div>If you’re sure that your “fPresentationTime”s are accurate, then sorry, I don’t have any other suggestion; perhaps the problem is with your client application?</div><div><br class=""><blockquote type="cite" class=""><div class=""><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;" class="">
<div class="">2. We still need to stream JPEG+AAC live streaming.</div>
<div class=""> After playing 2 minutes, video will block which is same with H264+AAC issue.</div>
<div class=""> There is no DiscreteFramer class for JPEG streaming, do you have any suggestions?</div></div></div></blockquote><div><br class=""></div>Yes - my suggestion is not to stream JPEG; it’s a bad idea.
