hi guys,
having researched the forum recently about the above device in an AppleTV, i made the plunge. the unit is installed, and i have verified its operational at boot time and selected it as the renderer in xbmx settings.
the source for the media is on a USB drive attached to my iMac. this is shared via an FTP share, across my 100Mbps LAN. i have verified that this is running at optimal throughputs with network traces. this causes no issues for SD content, or HD content played through native QuickTime player on the ATV (alot of my films have already been converted to .m4v, specifically for the ATV).
playback of HD sources through the Crystal HD unit is stuttering, quite badly. i am presuming that the fps is too low, though on this platform, i dont know how to bring up stream debug-type info at the top of the screen (on my linux box, this was the Enter button, but doesnt seem to be an equivalent on ATV)
the main test was against a sample file of the Inglorious Basterds film, as it was smaller to copy around, etc. below is the details from MediaInfo regarding the encoding of the film:
instead, i have copied 2 xbmc.log files (normal & debugging), links here:
normal
debugging
if i attempt to watch a full blown film, it is forever buffering during playback, then few seconds of playback, before buffering again.
i wasnt aware of any other settings to apply, and thought this was relatively straight forward process. i am hoping someone maybe able to offer more insight into my issue(s)...
regards
