@popcornmix: I'm just viewing a fairly low bit rate HD movie over NFS (DTS 1536 kb/s audio, h264 1280x544 video with a typical video bit rate of 4-5Mb/s), and I've noticed that vq is very low, in fact it's mostly 0% even though CPU is only 40% and vf is 100%.
Is this a problem (vq == 0), or is it simply that ffmpeg read ahead (readbufferfactor is 4.0) doesn't need to read ahead at all as there is more than sufficient network bandwidth to supply the video queue with data as it is needed? The Pi is reading about 800KB/second.
