However, I'm going insane trying to get 720p mkv files to play correctly using the MEncoder to transcode. They start up quickly and run perfectly for about 45 minutes. Then the bitrate drops to zero, even with the buffer full, and the video stutters repetitively for the remainder of the film every 10 minutes or so. Please help me! My wife is losing patience with my "experiment" and wants to go back to just watching DVDs and Blu-Rays.
My setup is a MacBook Pro 2.16 GHz Intel Core Duo with 2GB 667 MHz DDR2 SDRAM running Mac OS X 10.6.4 and PS3MS 1.20.409
My network is as follows: MacBook Pro <-100mbps ethernet cord-> Linksys WRT54GS Router <-Wifi G-> PS3.
I've tried a variety of options. keyint=1:vqscale=1:vqmin=2 as well as keyint=25:vqmax=5:vqmin=2. My buffer is currently set at 400mb, though I've tried everywhere in between that and 600mb in increments of 50mb. I've set my number of cores used for transcoding to 2 and have also attempted 4, per my reading a suggestion in another thread. Audio channels are set to 2 (stereo) and AC3 audio bitrate is 384kbps. Maximum bandwidth is set at 15 (per suggestion). I've also tried 14, 0 (no limit), and 54. Enhanced multicore support is checked, as is A/V sync alternative method, Force framerate parsed from FFMpeg, and switch to tsMuxer when h264 video is ps3 compatible. I exit out of all running applications before attempting to stream and make sure there is no other stress on the network during streaming. I've reset my MacBook, router, PS3, and the server countless times. It is my understanding that a 720p mkv file should stream comfortably over a wifi G connection in well under 54mpbs. So where's my problem? HELP!
