[PROBLEM] Video Stutter

[mk01]

@nertskull

ok, tried. so much times and combinations that I know all the people involved in the movie. and will remember them for ever.

got the same shutters. then changed nfs mount options and used

Code:

vers=3,rsize=262144,wsize=65536

I have NFS4 support on my server so vers=3 might not be needed on your setup. by default the nfs mount creates buffers of 1M (read/write). Normally I never use more than 65536 (to get lower latency) but was never forced to use it (like this one) - now just have one argument more not to use such big buffers.

one more thing, there is smsc95xx.turbo_mode=Y used in Beta2 (/boot/cmdline.txt). It wasn't used with Beta1x as in general this can lead to conflict and nasty things under navy load - some irq conflicts with net/sd etc. but since this got much better will all to patches to RPI kernel, I decided to try with Beta2. you get a little more speed on net, but you get lets say worse overall performance if there is lot traffic on net, sd card and other devices. just want to say you can (in the worst case) change it to smsc95xx.turbo_mode=N.

in any case the buffers change was for me enough to play the video with sw DTS decode without shutters. still I always get ONE at the very beginning (in first 5s) but then no single one until finish.

report back.
