<div>hi, gstreamers <br><br>I can play mpegts files which contains h264 video 
and aac audio. But when I play mp4 files, qtdemux parse them to h264 video and 
aac audio, but my hardware decoders cannot decode them. I see the logs below 
<br>/GstPlayBin2:playbin20/GstURIDecodeBin:uridecodebin0.GstGhostPad:src0: caps 
= video/x-h264, level=(string)4.1, profile=(string)main, codec_data 
<br>(buffer)014d4029ffe10018674d4029b91816824d080000030008000003019478c189c001000468ee0fc8, 
width=(i <br>nt)720, height=(int)576, framerate=(fraction)30000/1001, 
pixel-aspect-ratio=(fraction)16/15 <br><br>I try to search some info about this 
from internet, but still not aware of this. So how I can deal with codec_data? 
any suggestions for this or any examples for this ? <br><br>Best regards, 
<br>zqhuan </div>
