Hi.
I have a Blu-ray ISO, that I try to playback via FTP on my local network (FTP server in house).
The video is stopping on eath 30-60 sec. to buffer up, and then starts again. The CPU load is 98-100% on my RPI.
If I connect via SMB to the same local server, playback works fine, and the CPU load is about 50%.
Is ther a setting, that I have overlooked, when using FTP ??
I have tryed many settings for the video buffering, but no one works for me.
The problem is only when I playback Blu-ray via FTP.
It's a 512MB Pi running 1GHz.
It look strange that the FTP protocol use 50% more CPU than the SMB protocol.
I have allso tryed to test my FTP server localy, at I can pull 10 times more bandwith from it, than the Pi playback via FTP use. So it's not my FTP server that have a problem.
When I Playback Blu-ray via FTP the CPU load is 98-100% and the video stop/start each 50-60 sec.
When I Playback Blu-ray via SMB the CPU load is 50-70% and playback works fine.
When I playback a SD movie via FTP protocol, the CPU load is 60-70%
When I playback a SD movie via SMB protocol, the CPU load is 30-50%
I test via the same SD video in both cases.. and the playback do not start/stop via FTP. Only if I playback a Blu-ray via FTP, then the CPU goes to ~100% load.
Hmm.. The FTP protocol is normaly a more simple protocol, than the SMB. So I can't see why it takes more CPU time, to use FTP ?!?
It's the same on openELEC (4.0.7), Helix and allso tryed Raspbmc. All showes the same issue.
Best regards
