Hi everyone,

I have maybe a silly question;

Is there any possibility to create test video files that would be used for tests and benchmark purposes so whenever there is an issue with buffering, format playing or networking it would be easier to troubleshoot because everyone will be able to test it and maybe to reproduce those issues?

I am not an expert so I am just wondering whether this would anyhow help developers and us users to easy a support on this great software.

That is what I meant thank you. As I can see those are 1080p files wouldn't it be better for tests on aTV to use 720p movies?

Memphiz and would that 1280x720 (720p) MP4 file with surround sound (AC3) work as a good reference? Sorry just want to confirm that.

don't use the planet earth sample. We already know it won't work with most HW video decoders, including the one in the ATV2. That sample file is just very.. absurd.

I use some of the files from the NMT test DVD as it has a lot of different bit rates and audio codecs. There was a newer one around too, but I couldn't find the link (I think it was called DVD9 something).

nope ... the mp4 file is like xvid only mpeg4 part2. The H.264 file 720p should work because it gets the hw decoder ...

I did some tests with rather both files just to show that buffering issues that I see lately (past 2 weeks) and that I reported in other thread. Both files were downloaded from that website (http://bigbuckbunny.org) using a German link Both of them show significant buffering issues (2nd rather more than the first one).

What you might try:

- using SMB (since your media are on NAS)
- setting audio to 16bit (or something similar in Apple system settings do not remember exactly)
- deleting temporarily

Code:

<audio>
                       <defaultplayer>dvdplayer</defaultplayer>
             </audio>

too see if that makes any change.

Did check already all of those settings before except deleting temp files (that I don't know where they are located on aTV):

• used SMB, NFS and AFP
  
• dvdplayer line is properly included in advancedsettings.xml
  
• audio output is set to 16bit
  

Anyway thank you

What I meant is removing dvdplayer lines form advanced setting temporarily.

I will give it a try in the afternoon once I am back home but you might be right - inside of the logs are plenty of errors like this.

22:46:50 T:158130176 DEBUG: CDVDPlayerAudio:: Discontinuity - was:51804263.958562, should be:51691115.208562, error:-113148.750000

Not very positive if it has to do something about a bad audio setting or if thats only because the ATV CPU is really overloaded - true is that my Yamaha AV Receiver always blinks about bad input when that buffering happens.

I will give it a try in the afternoon and will try to keep the whole advancedsettings.xml clean.

Thank you,

Strange. Do you have AC3 capable receiver and DTS capable receiver set in system settings? The only thing i can imagine that it stutters is that atv2 has to mixdown the aac multichannel audio into a stereo audio or something.

BTW - crashlog is only needed when a crash occured (and your link doesn't even link to a correct crash log )

I wanted to provide all logs that are in FAQ {sorry I knew I will mess something its located in /log instead of /logs right?}

But both settings that you mentioned are set in the system menu - I will try to set those in advancedsettings.xml as well just to be double positive after those tests.
