SVCDs have blocky, ugly colored picture (Pic inside)

Posted in xn--kfs74mzzid01b.com edit by cfz on January 8th, 2009

Hi!

I�ve updated xbmc to the latest T3CH (15-05 / 8943) and tried to play a few SVCDs. They have all picture errors and the sound is distorted. Here�s a picture example:

It was a fresh install in a new folder. Here�s the debug-log:

Some users on the german evo-x.de-forums have the same picture and sound errors.
----------------
PAL Xbox 1.0
SmartXX V2 Chip with X2 4983 or 79 (?) modified BIOS
XBMC as Dash with T3CH-shortcut
Philips SD-M32 DVD-ROM
60GB HD not lockable
----------------
If it�s a "real bug" and you want me to post a bug-report on SF then i�ll do :nod:

thx in advance for fixing it :rolleyes:

Just tried more builds: (tested from newer builds backwards)
svn 8306: didn�t work
svn 8233: can�t test because of 404 error on T3CH�s site
svn 8103: Can�t play file from the CD. Autostart and from the filmanager didn�t work. From HD the file didn�t work, too
svn: 7937: This is very strange. The mpg-file works from CD, but not from HD :eek:

Hi,

same thing here. :blush:

Build from 07.05.

very nice samples, they show the issue quite nicely. there is repetetive pattern of bytes in the broken file. something definatly goes wrong.

Remember the xbox dvd drives are junk.. they are picky about media as well as formatting. Can you try other medias and see if its universal?

... here u are. (took some time finding an suitable tool on linux)

I have the same problem, tried several svcds and they all look ugly and blocky - hope you can fix that soon - keep up the good work! A big THX to all the guys who spend their free time with enhancing this great piece of software!!! :nod:

Well, we�ll see.
Thanks anyway. :)

HI,

some more information:

As I said, I copied the .mpg to xbox hdd. I did that with an "non-working" copy of xbmc. After that the file was damaged, also if I played it with my "working" copy or even on PC. (same errors!)
On the other hand I copied the same .mpg from same disc, with the working copy, the file on hdd was ok on both builds. So for me it seems to be a disc-reading problem?
I�ll now cut off a slice and post it.

Tried with the same SVCD:
2.01 final: worked :nod:
svn 7667: worked :nod:
svn 8014: worked :nod:
i�ll test more builds tomorrow

so did this used to work? if you could try same sample with an older build and make sure it works it would be nice.

right.. hmm. have any of you guys tried playing the file locally or is it just from disc?

Hi,
same error here.
I tried several builds from april and may, playing svcds (and vcds) does not work.

I also tried a really old build, from jan 2007 (old xbmclinks build), NO problems there. Same disc of course.

I have no idea where te bug is in our somewhat convoluted iso9660 support so i'm rewriting the iso9660 support to use libcdio, can't say how long it will take thou.

Okey, that is very interesting. Could you get me a slice of both the copy that works and the one that is broken. It does indeed sound like a file reading issue.

.. yes, I did, copied the mpeg to box hdd. But it didn�t work either.

Hi,

i just did a test and can comfirm it works fine now.
Thanks for this quick solution, great work.

f

ok.. i want into a wall on the cdio rewrite. found the issue in our old code thou, so it should be fine now.

Hi!
little bit OT: (maybe a sideeffect of this bug)
I wanted to try copying mpg-files by myself to test the reading error. The older XBMC-versions worked fine, but in the newest T3CH 8943 i can�t access my CDs in the filemanager. It shows the Drive as empty. With "My Videos" and the Start-Button the CDs worked fine. Did some further testing:
SVCD - not working (shows as empty)
Xbox-Game - yes
CD with avi - not working
CD with mp3s - not working
DVD-video - yes
Maybe it�s because of the iso filesystem on the CDs? I have no advancedsettings.xml

Remember the xbox dvd drives are junk.. they are picky about media as well as formatting. Can you try other medias and see if its universal?
The older XBMC-versions worked fine, but in the newest T3CH 8943 i can�t access my CDs in the filemanager.
The disks where all the time in the drive, i just switched the XBMC-Version via the file manager. The disks played fine from the menu or via the start-button but NOT in the filemanager. it shows "empty" (only in the newest T3CH).

if somebody could chop of a sample of a svcd somewhere and upload for me i'd be much obliged.
