Great. Looking forward to hearing what you find and what optimizations you think there might be

Could it be that transcoding to a 60fps video uses more cpu..
(its 60fps according to vlc. I dont set a frame rate when I transcode )
I'm guessing plex is transcoding to something lower like 24/30fps?

So I assume less frames equals lower cpu usage? I'll test this later tonight

That might actually be why I get the "jumpy" video on the iPad? Fingers crossed...

test this . it fixed the occasional stutter/jump that was happening for me!
i'm not sure if its the same jumpy video that you saw though

DELTED: http://www.mediafire.com/?lmzsctqnrc138k9 - didnt fix anything

seems what really fixed my stutter was my cpu upgrade

todo: update vlc interface to match flash web interface

I just tried the new file and the playback still seems pretty jumpy on CBS HD but works smooth on ABC HD, NBC HD, and ESPN HD (the ticker at the bottom of ESPN that scrolls across looked pretty smooth too)! For CBS, it also played audio for the first couple seconds then the audio completely cut out! (720p, low quality, wireless-n network on new ipad 3). vlc looks to still be around 70-80% cpu on either channel sometimes spiking to 90%. Did you just change the frame rate? And only issue on ESPN is it played back for about 10 seconds then the feed all of a sudden stopped for some reason (any clue how to debug that?)

FOLLOWUP: I tried 1080, low quality, and ESPN HD and ABC HD are both essentially unwatchable. Very very jerky.

The CPU usage appears to have gone up. On 720, low quality, i'm around 85-95% CPU whereas before it was around 70-80. And playback does not begin for some reason after I click the play icon that appears on the ipad (i get a "The operation could not be completed" on the ipad).

Is there any reason you're using vlc for transcoding vs. using something like ffmpeg?

I use vlc because it saves me alot of coding

this one seems a bit better for me:
720 low quality I'm at 12-20% cpu (down from 16-25%) and 1080 around 30% cpu (didnt test this last time)

720 seems about the same... and sometimes I just get a black screen and no play button (and CPU is pegged in the 90s for 1080). 720 is definitely "good enough" for now . But curious on why I get no play button despite the stream starting. Can you describe what tweaks have you been making?

Any progress on Android development? I would love to be able to watch TV on my Xoom tablet.
