回复: Re: How can I deal with the codec_data after qtdemux?

hi, Aihua Zhao

Thank you for your reply. I check the link you offer, but not very clear of it. 
Now I can get the codec_data, then I need to parse it and got the PPS and SPS, right? After that, I need to package PPS and SPS to a GstBuffer and pass it downstream, but how can I package GstH264PPS to a GstBuffer, and does it work for me?

Best regards, 
zqhuan

hi, gstreamers 

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 
/GstPlayBin2:playbin20/GstURIDecodeBin:uridecodebin0.GstGhostPad:src0: caps = video/x-h264, level=(string)4.1, profile=(string)main, codec_data 
(buffer)014d4029ffe10018674d4029b91816824d080000030008000003019478c189c001000468ee0fc8, width=(i 
nt)720, height=(int)576, framerate=(fraction)30000/1001, pixel-aspect-ratio=(fraction)16/15 

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 ? 

Best regards, 
zqhuan
