<div>Hi,</div>
<div> </div>
<div>I am not sure if this is the right place to ask this question. We have been trying to decode RTMP stream, but I am encounter error when we try using vpudec although ffdec_h264 works fine. Problem is we cannot use SW decode for 1080P video. </div>
<div> </div>
<div>If some experts throw some ideas it will be very useful. When using vpudec, it shows UNKNOWN FORMAT error(logs below). While flvdemux has same x-264 avc format as src pad. </div>
