Which sample code you are using to decode the attached file?
What is the images/video format, etc,
The file use pcap extension. Is the data in the pcap file package? The UMC simpleplayer does not support such package. Raw H.264 or H.264 in MP4, MPEG TS container can be played with the UMC simpler player application.
btw, IPP 5.3 is a pretty old version. When you do some test, maybe you can try the new IPP 6.1 version or the upcoming IPP 7.0
