Hi,<br><br>On the Intel Linux Graphics site, a summary of supported features is given (<a href="http://intellinuxgraphics.org/vaapi.html">http://intellinuxgraphics.org/vaapi.html</a>). For H264, High profile is supported "up to 40 Mbps". This 40Mbps, is this independent of the complexity of the clip?<div>
<br></div><div>I have 3 H264 test clips at different bitrates. Using software decoding, the different clips at the same bitrate will behave differently: some clips decode fine @ 20mbps while others have severe frame drops @ 20mbps => the complexity of the clip information is probably an issue here.</div>
<div>I don't see this behavior with my test clips when using VAAPI. All clips, even the most complex ones, play fine even @ 40mbps. This is great, but I wonder if bitrate is indeed the only factor that influences the video decoding performance on Intel? So can I assume that any clip @ 40mbps will play fine?</div>
<div><div><br></div><div>And what about playing multiple clips at the same time. I can play 2 40mbit h264 clips fine, but 3 clips sometimes gives severe framedrops depending on the clips I'm using. How should I interpret the 40 mbps limit mentioned on the Intel page now? I can play multiple clips fine as long as the total bitrate is <= 40 mbit? But 2 clips at 40 mbps seem to play fine here...<br>
<br>Btw, I'm using an Intel Huron River platform.</div></div><div><br></div><div>Best regards,</div><div><br></div><div>Christophe</div>
