I have a single backend driving 2 frontends - all debian based. I recently updated them al to the 2.6.11 kernel kernel-image-2.6.11-1-686 I now have a significant amount of 'stutter' druing playback on both frontends
Each frontend has a slightly different hardware config (mobo, audio, cpu speed) but the same video card (nvidia), intel procs, etc. The backend is capturing everything fine because if I copy the .nuv file over to a windows box or to my videos dir they play fine (including in mplayer), it is just during myth playback that the problem seems to exist. I have tried the following: - renice the mythfrontend process - renice the mythbackend process - set use video as timebase - set agressive audio buffering - monitored my local lan (100Mb FDX) to look for network congestion Does anyone have any suggestions as to what may be causing this? Is it a myth problem, or a linux kernel problem? FWIW, I captured a number of prebuffering messages in the mythfrontend log: 2005-04-07 23:36:45.567 WriteAudio: Preparing 4096 bytes (1024 frames) 2005-04-07 23:36:45.567 audio waiting for space on soundcard: have 368 need 4096 2005-04-07 23:36:45.574 audio waiting for space on soundcard: have 1676 need 409 6 2005-04-07 23:36:45.581 audio waiting for space on soundcard: have 3020 need 409 6 2005-04-07 23:36:45.588 Broadcasting free space avail 2005-04-07 23:36:45.588 WriteAudio: Preparing 4096 bytes (1024 frames) 2005-04-07 23:36:45.588 audio waiting for buffer to fill: have 512 want 4096 2005-04-07 23:36:45.588 Broadcasting free space avail 2005-04-07 23:36:45.592 audio waiting for buffer to fill: have 512 want 4096 2005-04-07 23:36:45.592 Broadcasting free space avail 2005-04-07 23:36:45.596 audio waiting for buffer to fill: have 512 want 4096 2005-04-07 23:36:45.596 Broadcasting free space avail 2005-04-07 23:36:45.600 audio waiting for buffer to fill: have 512 want 4096 2005-04-07 23:36:45.600 Broadcasting free space avail 2005-04-07 23:36:45.604 audio waiting for buffer to fill: have 512 want 4096 2005-04-07 23:36:45.604 Broadcasting free space avail 2005-04-07 23:36:45.608 audio waiting for buffer to fill: have 512 want 4096 2005-04-07 23:36:45.608 Broadcasting free space avail 2005-04-07 23:36:45.612 audio waiting for buffer to fill: have 512 want 4096 2005-04-07 23:36:45.612 Broadcasting free space avail 2005-04-07 23:36:45.616 audio waiting for buffer to fill: have 512 want 4096 : Thanks in advance - any help would be muchly appreciated Troy _______________________________________________ mythtv-users mailing list [email protected] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
