ATV buffering this movie, Is bitrate too high? - kedda - 2012-03-14 All, This file is struggling to play on the AppleTV1. I receive consistent buffering. I read that XBMC buffers at 2x the bitrate. I have verified my ATV can and network can comfortably do up to 80 mbps. The image below shows the peaks and valleys of the file. The max bitrate is 44128kbps. The average bitrate is 31198kbps. Why is this buffering? RE: ATV buffering this movie, Is bitrate too high? - Ned Scott - 2012-03-14 Do you have a Broadcom Crystal HD (wiki) card installed on the Apple TV 1? RE: ATV buffering this movie, Is bitrate too high? - kedda - 2012-03-14 Yes. I have the 15 version. the drivers are installed and the box is checked within XBMC RE: ATV buffering this movie, Is bitrate too high? - kedda - 2012-03-15 I should also mention that the movie played perfectly when it was locally stored. i.e. stored on the appletv. RE: ATV buffering this movie, Is bitrate too high? - kedda - 2012-03-15 I can also post additional media info if necessary. However, I think all that is needed is listed above RE: ATV buffering this movie, Is bitrate too high? - interceptor121 - 2012-03-15 You need media info that graph says nothing useful on how the file has been encoded RE: ATV buffering this movie, Is bitrate too high? - kedda - 2012-03-15 Ok, Here it is.... Like I said, it played fien when I copied it onto the ATV1. Code: General RE: ATV buffering this movie, Is bitrate too high? - Ned Scott - 2012-03-16 What protocol are you using to share the files over the network? SMB? AFP? NFS? It's possible there's some weird overhead that pops in and out that will cause occasional buffering. RE: ATV buffering this movie, Is bitrate too high? - interceptor121 - 2012-03-16 When you say that this plays perfectly locally what do you exactly mean? Have you let this movie play for say half hour and checked that it does not drop frames? And what is the file server and how do you connect to it? RE: ATV buffering this movie, Is bitrate too high? - kedda - 2012-03-16 I have tried SMB, NFS and FTP. In order of best to worst it has been FTP -> SMB -> NFS. All being served up from a Windows Home Server 2011. FTP is the closest, but I see that little streaming pop up message in bottom corner of screen saying "cache filled before reaching required amount..." Clicking "o" on keyboard I can see aq and vq struggling to stay above 0. I see that MBit/s range from 28-38 Mb but the machine is capable of 80Mb and I have seen it pull there. some interesting things from log are... Code: CDVDInputStreamFile::SetReadRate - set cache throttle rate to 5113603 bytes per second Code: DEBUG: CDVDPlayerAudio:: Discontinuity - was:1624238138.422667, should be:1624233699.666667, error:-4438.756000 Code: WARNING: CCoreAudioPerformance: Outgoing bitrate is lagging. Target: 576000, Actual: 569441. deltaTime was 1010 Code: WARNING: CDVDMessageQueue(video)::Get - asked for new data packet, with nothing available (2012-03-16, 05:51)Ned Scott Wrote: What protocol are you using to share the files over the network?

Yes, I have let it play for the entire movie and it did not drop frames when played off of the atv not the network. connected to windows home server 2011. sharing options are ftp, smb and nfs. in order of success its ftp -> nfs -> smb.

RE: ATV buffering this movie, Is bitrate too high? - kedda - 2012-03-16 The log is too big to fit on pastebin so I posted it to skydrive. XBMC.log The first 10,100+ lines are a result of playing over the network. Lines ~10200 - 10400 are playing the file from the machine. What's weird is all the references to the iron man 2 bluray. I have no idea why its trying to open that. Before you ask, I am using ftp://127.0.0.1 so that I can use mysql. I do file substitution on the apple tv to redirect to 192.168.1.120. I have also trying accessing the ftp server directly without the file substitution, no difference. RE: ATV buffering this movie, Is bitrate too high? - kedda - 2012-03-19 anyone have any thoughts on this? does anyone think this could be a bug associated with TrueHD or DTS-HD decoding. |
