SD movies stutter, HD movies play fine - flanker - 24th May, 2015 06:21 AM HW is Pi2. Running latest version of Xbian (14.2 i believe) with all the updates. Movie library is on another Pi2 connected via Samba and Ethernet cable. My problem is as title says. I can play Blueray movies no problem. Yet whenever I try to play 480p movies it stutters like mad. And it's not just the video. Whole UI becomes sluggish. Tried to downgrade to 14.1.(sudo apt-get install xbian-package-xbmc=14.1-1423177674 ) Same results. I'm not 100% sure, but I believe I used to play SD movies without issue a few weeks ago. I did an update 3-4 days ago and there were tons of stuff on the list. I think one of them is messed up. Only other thing that comes to mind is, maybe I need licences for the codecs in the settings? Ayone else having such a problem? <Edit 1> I think I got the problem. All the movies that stutter has AC3 audio codec. Ones with AAC doesn't stutter. Did we get an update to AC3 codec recently? <Edit 2> MP3 audio encoded videos also stutters, Dolby files don't. <Edit 3> Did a snapshot restore to a month ago. Didn't help. Updating all again. Also deleted advancedsettings file. I used to have caching related stuff in it. Also didn't help. <Edit 4> Enabled debugging. FPS counter shows solid 24 fps yet what I'm getting at is definitely not 24fps. CPUs don't go above 20% While looking at the log files I noticed some weird stuff going on with FFmpeg. Someone more knowledgable could make something out of it hopefully... Debug file is attached. <Edit 5> Fixed! Reverted all playback options and video options to default and increased buffer size. Now it's working as it should. I wonder what caused it. I'll keep messing with it. ![]() <Edit 6> Found the culpit. It's my fckin logitech wireless headphones again... I switched to xbian just so that I could use these things, now they are giving me headache here too... Here is the deal: when I output audio tru HDMI I get butter smooth playback. When I route it thru my wireless headphones, I get stutter. I tried passthrough, didn't work. I know that I didn't have such a problem a week ago. So one of the recent updates caused this. I'll keep looking at it. It's really weird tho, I feel like I'm the only one who uses his pi media station with wireless headphones. RE: SD movies stutter, HD movies play fine - flanker - 24th May, 2015 08:30 AM OK. Here is the final situation. -If I go with default settings for all and use TV's hdmi, all is well. -If I disable MMAL hardware accel. movie runs smooth with headphones or HDMI. But then I can't watch HD movies(software decoder isn't beefy enough I guess...) -If I try to watch an SD video with default settings + Headphones as audio output, I get flashing subtitles and choppy video. Possible Solution: I need an addon that can disable HW acceleration for SD movies and enable them for HD. RE: SD movies stutter, HD movies play fine - flanker - 26th May, 2015 07:36 AM Gave up. Switched to OpenElec. The latest beta doesn't seem to have the stable one's cracking sound problem with Logitech headphones. |
