Large-sized MPEG-2 file playback a tad wonky in PS3?

Posted May 21, 2007 at 5:28PM EST by QJ Staff

Listed in: PS3 Tags: Sony

Although Tommi Pisto's email tip, represented by the JPEG you're looking at stage right, makes the case perfectly clear, why it's happening that the PS3's playback of larger-than-4GB MPEG-2 video files is rather shot. Although the menu language isn't English, the running commentary and the results are still perfectly understood.

In those test cases, the PS3 can't properly read files larger than 4GB, leading to a screwy inability to track (rewind/fast forward) through the video. As Tommi notes, this bug makes the PS3 ineffective as a home media center "for those who wants to watch their own captured (Sony HDV digital camcorder) files (one hour cassette = 10GB)." In short, it could spark home video issues.

Well thanks, Tommi, for bringing this to light. Now we wonder if this is a firmware thing, possibly encouraging a future update to correct it. Too bad we don't know what firmware Tommi experimented on. We wonder if Sony's aware of this and if this is an isolated case or not.

Its not likely to be fixed for a very long time. Its a File system issue. It most likely will require a severe overhaul to the PS3 oS & a complete format of your PS3's harddrive. I'm sure they won't leave it like this but for now I'd say its gonna stay like this for awhile. I'm amazed he got anything over 4GB to work.

the pic is 192x480 pixels. how do i take a closer look? it's a little hard to see anything in that small pic.

The PS3 uses Fat32 and can only read Fat32 for some reason...

This is why Mac formatted iPods can't be viewed on the PS3, etc., etc.

Does anyone know why they went with Fat32?

# Too big ? — Guest 2007-05-21 21:13

The reason that the PS3 cannot handle files bigger than 4 Gb could be to stop piracy. Think about it, if the PS3 cannot read properly these files, and knowing that most games are larger than 4Gb, it will help preventing again illegal copy and potential iso loaders... Fat32 is particularly handy in this case, isn't it !!!!

# I agree! — Guest 2007-05-21 22:28

these is good for now.

# meh — comedy 2007-05-22 00:15

here's an idea, all of you who are wasting so much space on home video files in mpeg2 re-encode it to something like x264 and you can reduce the size by a great deal. if you want to play it on the ps3, reencode it to avc etc.

yeah, it would be nice if the thing played files over 4 gigs, but you can work aroudn it if you want: cut it into a couple of files, reencode, watch it on something else.

# :D — Guest 2007-05-22 02:50

Fat32 is better, not to mention MS owns the other format (ACSsomething?) ;3 lol

# no.. — Guest 2007-05-22 03:10

4GB (2^32) is a typical limitation of a 32bit file or memory system. Versions of windows which use FAT32 have the same problem, and so do Macs using an older OS. This shouldn't be news to anyone who has tried to do video editing in the past few years.

# . — Guest 2007-05-22 03:34

But the PS3 is supposed to be the all in one media center!

# >> — Guest 2007-05-22 05:23

i can play >4GB files usin ps3 linux streamed from pc, so no probs for me

# Ahhh... — Shatterdome 2007-05-22 06:03

Well, FAT32...that explains it all now.

That is just funny stuff....although NTFS was brought around by microsoft, I doubt that they own the rights on it...but I suppose it's possible....however I beleive other systems have used NTFS other then MS....

Well then, yes, to change this it would require a format AND a firmware upgrade....very *****ty...

BTW fat32 is NOT better then NTFS....in more ways then I care to list....

# mostly agree with blade... — Guest 2007-05-22 06:29

The hard drive is not formatted FAT32. It would still most likely be the file system, but I can tell you it's not FAT... You would have to reformat the drive if this were to change.

# The only problem is: — Guest 2007-05-22 07:43

the PS3 is too slow without hardware framebuffer access to display a video FULLSCREEN on Linux!

So you can play the videos... but they are to slow and have too less FPS

# ext2 — Guest 2007-05-22 09:20

PS3 is never going to use NTFS but there is no reason to use it anyway.

If rumours are right about the GameOS being a linux derivative they could use any linux filesystem (ext2, ext3, ...).

ext2/3 is one of the most robust filesystem you can dream of and max filesize is 4 terabytes. ext2 was developed in 1993 so it has been around for a very long time.

# Filesystem — Guest 2007-05-22 10:35

Just because the PS3 supports FAT/FAT32 USB cards does not mean its internal File System is FAT32 as well.

At any rate, there are other bugs in the media player, such as with AAC files...

# Here's a thought... — Shatterdome 2007-05-22 12:33

What if someone wants to keep the 1080P resolution of their HD file that they just recorded with a sony HD camcorder, and want to play it using their Sony PS3 on their Sony 1080P overpriced HDTV.....oh yeah...they can't....so then whats the point of HD again ?

# Huh? What the?... — Guest 2007-05-22 16:29

One question: How the heck could he transfer a file larger than 4GB onto the PS3 to test in the first place? I couldn't put any media file larger than 4GB on ANY media I've tried... not even a dual-layer DVD would be able to house such a thing. And where is the source of this news? I'd like to see how he did it.

# uh — Guest 2007-05-22 17:25

Red Kawa PS3 Media Center, goes to File System, downloads the file straight from his PC.

# Hmm... — Guest 2007-05-22 18:36

I see. I'll experiment with a 1080p MPEG-2 TS file on 1.70 and see if it indeed cannot rewind/fastforward as well as the separated 4GB files.

# sigh.... — Guest 2007-05-23 01:00

What a weak and pathetic way to use Linux.

Can't even play a damn video.

# Well — Guest 2007-05-23 02:41

Shatterdome:

I guess they will just connect that HD camera straight to the fancy HDTV then =)

# thador? — Guest 2007-05-23 11:38

B.B. is saying that's why they used fat32. It's known that it has problems with files over 4gb, thus sony used it to limit what you can do.
