[solved] Stuttering - solution: xvid 720p is not h.264 - mchick - 2012-02-08 Things we want from EVERY report: Platform: ATV2 Version of iOS/ATV: 11.0.0 AppleTV2,1, Version 5.0.1 XBMC Build version: Build 9A406a Built on Dec 24 2011 (Git:20111222-22ad8e4) Install method - sshed into ATV2 Detailed Instructions to Reproduce the Problem - Play Video Skin name: Transparency File Share: NFS using haneWIN(also tried mac NFS) Playback Problems: During playback of large HD videos, over 2gb, videos begin to stutter and buffer excessively. I thought SMB was the issue so I gave NFS a try. I am running wireless N. However tried a wire connections with no change. Media File Details: VIDEO.......: 3151 Kbps AUDIO.......: AC3 5.1 - 448 Kbps SIZE........: 2.55 GB FRAMERATE...: 23.976 NTSC RESOLUTION..: 1280x544 SA..........: BVOP: Yes QPEL: No GMC.: No Log: http://pastebin.com/8PTdfCYV - Memphiz - 2012-02-08 Well multiple things: Code: 894.01:39:33 T:149889024 ERROR: ffmpeg[8EF2000]: [ac3] frame sync error 1. that file looks broken to me. 2. Be sure to use the latest hanewin version 3. I recommend using beta2 instead of 1 (or wait a few days for beta3 if you want) 4. The stuttering is because of the above - its all over the log. Looks like that ac3 stream is broken in that file 5. Please provide a full mediainfo output (google mediainfo for the right tool) And last but most important - as of the log this is mpeg4 part2 (aka xvid/divx) - and according to the filename it is > SD resolution (720p). Read the iOS FAQ in the wiki. These kind of files are not hardware decoded and therefore won't play stutterfree on the atv2 at the moment. Use h.264 encoded content for HD resolutions. Problem cleared i think... - Memphiz - 2012-02-08 And now i change that topic because it has nothing to do with NFS at all! - mchick - 2012-02-09 Wow thanks. After I posted I did some more research and saw that is was as you have stated here. Anyway I got another file here that is having some issue when I try to play it. At random times the fps goes way down to like 7 and the whole video stutters. I was wondering if you could take a look at the log file and see what could be causing this.

Logfiles says 4 refframes. Either these are 2 different versions of that file or it is b0rked or ffmpeg in XBMC doesn't detect it correct. Beside that double check that thumbnailextraction is turned off in settings (see the iOS faq on how to do that). - mchick - 2012-02-09 Here is another log. In this one the ref frames match up. Same mediainfo as above. http://pastebin.com/pWnxdz4c During the playback I saw roughly 5 dips to around 7fps. It seems to me this another situation were there is something wrong with the encoding/file. Addition: I also followed the faq for reducing buffering. - mchick - 2012-02-09 Edit: Removed |
