Looking for problem video files

Wed Oct 26, 2005 12:38 pm

In the next few weeks, Roku will be embarking on another concerted effort to address video compatibility issues. So I'm looking for problem video files.

If you can share with us any MPEG-2 TS or PS file that has playback problems (of any kind) on PhotoBridge software version 2.0.35, please send me a PM.

Thanks,
Dave

This is great news :D !!! All my 50Hz PAL rips stutter, they seems to coincide with chapter/file breaks and it's fixed with a pause > pause in MPlay... It happens maybe 2-3 times whilst watching a film, 60Hz NTSC rips work perfectly!!!

Is this a hint that the final release of 2.0 has not been abandoned?

We're all very pleased to hear that. I know I'm not the only one who is grateful to see resources being applied to getting a finshed 2.0 firmware shipping.

GIven the amount of work already done on the 2.0 firmware, I would imagine everyone at Roku would want to see it finished and shipping as the default firmware as soon as possible. The sooner all PBs ship with 2.0 firmware the better, IMHO.

Update -- the two vids I listed above play just fine now on the new beta, as do several others that used to not play. Very pleased to see this update!

I would tend to agree all bar one thing, which might not be roku and might be mplay.

If I open the sony demo sometimes mplay stutters badly, while opening it in cinemasix 1.6 is fine, only a reboot brings mplay back on line.

I marcelo3d.

It can be found in usenet

alt.binaries.hdtv

Sorry i deleted it from my ftp after daveroku grabbed it.

On a side note I can only play the sony one using nfs.
sometimes mplay handles the sony other times it stutters.
very odd and what or who is the issue i have no idea, but a click of the remote reboots the unit and im back in business with mplay.

I'm not set up for usenet downloads. Sorry.
If you have a file that produces the problem, please post it where I can download it or snail-mail it to me in a CD/DVD.

hdclips.net has all kinds of stuff. The troublesome Sony and LG demos are there, as is the Avril Lavigne clip that I couldn't play before downloading 2.0.36.

As an aside, that's a great site -- lots of cool little clips to download.

davidd provided me with the Sony demo. Here are my findings:
1. The file is really a Program Stream file, not a ts, as the extension says. At least that is what Cascade reports.
2. There are a couple of glitches in the file. About 3 in the first 3 minutes. They are tiny video jumps, like a frame or two are missing.
3. The file is very close to 25 Mbps.
4. The file plays fine with MPlay with my setup (WinXP, smb, wired eth)
5. Probably because file fragmentation, timing the copy of the file to /dev/null gives me 25Mbps.
6. I can play the file many times without it stuttering.

Once, during playback the image paused for a fraction of a sec and audio was lost. Considering that I'm at the limit of how fast the server can serve the file, I'm not surprised.

So, please check the network speed for streaming this specific file:
time cp sony1080i.ts /dev/null
Take the size of the file, multiply by 8 and divide by the number printed as "real", in seconds. If the result is less than 25000000, you have a server or network problem that prevents you from playing this file.
