A real strange problem ripping ??? Virus ?? or is it me

[Johnnysh]

Hi Guys

I have been away over the weekend, but great reading all the updates,

now whats really intresting is a few weeks ago I sent my test VOB file (Black Eyed Peas) to someone running Vista and windows media player and he said it played perfectly smooth ??

At this point, nothing made sense to me ?? I tried it on win 7 and xp and it played so jerky ????

Now I notice in the recent replys, that someone else with vista said it played fine too ?

So is this a problem with Windows 7 / XP or is there some other setting / codec / driver in Vista thats making NTSC files play smooth??

I do not own vista, but if it solves the problem I would consider buying it,

Though I feel it's going backwards and I am not getting to the bottom of this problem,

I know the quality of the file is not perfect, but I have the same problem from an orginal rip from a high quality Madonna DVD

I do appreciate your ideas and feedback

Regards

John

Did you try the files I uploaded? Do they play smoothly for you?

[Johnnysh]

Hi

Just tried both files on my windows XP machine

both files when played in media player 11 play in a jerky motion when moving as image is moving in a left direction, the same sort of jerky motion that I am getting with my ntsc videos

I am not getting any other defects in either file with lines or image quality, the lines are sharp and crisp.

I am watching this on a 21inch CRT refesh 140hz

I also have the same issues on other computer with flat screens

so no these files do not play smooth ? thanks for uploading these test files

This is so stange, why not smooth playback ???


thanks


One other strange thing a few weeks ago when playing with this problem in my DJ software, When I increased the bit rate setting inside software config area of the audio.

The video played back much more smoothly when viewing the ntsc video file, though the audio sounded much faster.

Now after reading a little about ReClock application it tells me when playing video files the video clock is taken from the audio ? and the application ReClick works by adding a new clock not related to the audio.

Could this be anything to do with my problem and why when speeding up the audio clock rate in my DJ video software it improoved the playback

Thanks

Ok after viewing the same two test files on my Win7 PC with a Flat Secreen monitor set to 60hz

I can say they do not play smoothly for me and worst than on my XP machine with a CRT monitor




1) both files have a comb edge even when paused in VLC, but in media player the edges are pin sharp with no comb edge

2) All lines are perfectly straight from top to bottom when paused in both players



3) In VLC Player When playing bff.mpg & tff.mpg I get a constant line with a slight off set about 5mm from the bottom of the video (full screen)
With random lines and an slight offset to the right from top to the bottom when image is moving/playing

Very jerky and choppy playback the image is almost breaking up at different times whilst it is playing

In Windows Media player I have a slightly different result

There is no line about 5mm up from the bottom, the image is still scrolling jerky

and I am getting random lines from left to right going across the image anywhere from the top of the image to the bottom

Sometimes it seems worst than others and each time I play the files it can give slightly different results

Its not always a line thats offset sometimes it can be a band area (larger than a line) thats offset slightly ??

In widows media player its Very jerky and choppy playback the image is almost breaking up at different times whilst it is playing


All i know is the xp machine has given much better results on a crt monitor than on this window 7 PC


Thanks for any feed back or ideas

There's is definitely something wrong with your computer(s).

For #1, you may have to manually set VLC to deinterlace. While playing select Video -> Deinterlace -> Bob, or Discard (the latter takes less CPU power but doesn't look as good with real video). It sounds like you are describing tearing in #3. This happens when the video frame buffer is changed while the graphics card is displaying the frame. The top part of the image you see is from one frame, the bottom from another. The tear usually moves up/down the screen while playing. When you pause the video the tear goes away (because the frame buffer is no longer changing, the graphics card is simply displaying the same frame over and over).

The first thing to try is changing the output device in VLC. Tools -> Preferences -> Video, in the Display box, try changing the Output pulldown to the different settings. See if any of them works better. VLC can be unreliable when changing this setting. I find it's best to exit and restart the program after changing this. Some of the options won't work and some are just silly (ascii art). Default and Windows GDI should work well.

What kind of CPU usage do you see at idle and when playing the simple TFF/BFF files?

Jagabo

thank you so much for your reply,

Yes you are right on the windows 7 pc I am seeing a tear effect, just was not sure how to decribe it, but yes its a tear effect.

The tear does move from the top to the bottom, I will continue to read your reply and change settings in VLC on the windows 7 PC



CPU idle toggles from 88 90 94 % when playing video

Ok tried what you have sugested with all video output options in VLC, some worked and displyed a video window, some did not

But none of them cured the video tearing fault !

None of my video cards here are the later type (HDMI out), I did try to buy one on saturday but I have got to change it as its faulty

Every card I have, both nvidia and ATI all have TV svideo out sockets, could this have anything to do with the tear effect ?? (i.e. being partly analogue TV output signals on the video card) ??

just an idea ??


So now I have to ask, what would cause in both VLC & WMP the frame buffer on the video card to keep changing whilst playing the video file ?? causing a tear effect ??

I do also have the shark 007 codec pack installed ?

Could this frame buffer change be down to a virus or nasty ?? I have scanned the pc over and over ??? and everything seems good ??

Thanks again

CPU idle toggles from 88 90 94 % when playing video

That's really high for playing an MPEG 2 video on a modern computer. I see essentially zero CPU usage when idle, 10 to 50 percent when playing an MPEG 2 video on a dual core Celeron -- depending on which output device and which deinterlacing mode I select. Your high CPU usage is probably related to your problem with MPEG 2 video. Although, I don't see why it would be much different with 25 fps PAL.

Ok tried what you have sugested with all video output options in VLC, some worked and displyed a video window, some did not

But none of them cured the video tearing fault !

VLC isn't the best of players for Win7. I would switch to something like MPCHC. But try this in VLC:

Go to Tools -> Preferences. At the bottom left select All in the Show Settings box. In the left pane expand the Video section. Then expand the Output module section and select DirectX. Make sure Triple Buffering is enabled. Also try changing the state of the two settings above it. In the Video -> Filters section make sure all filters are disabled.

None of my video cards here are the later type (HDMI out), I did try to buy one on saturday but I have got to change it as its faulty

Every card I have, both nvidia and ATI all have TV svideo out sockets, could this have anything to do with the tear effect ?? (i.e. being partly analogue TV output signals on the video card) ??

HDMI and s-video shouldn't have any effect on this issue.

So now I have to ask, what would cause in both VLC & WMP the frame buffer on the video card to keep changing whilst playing the video file ?? causing a tear effect ??

Windows graphics drivers have the ability to switch frame buffers only when the display isn't being drawn on the monitor by the graphics card. You may find a setting in the graphics card's setup applet that controls this. Look for mention of tearing, vertical blanking, VBI, etc.

I do also have the shark 007 codec pack installed ?

I don't know shark 007 but codec packs should usually be avoided. Especially with VLC which has no ability to use any external codecs. Still, they could install output drivers that could cause problems.

Could this frame buffer change be down to a virus or nasty ?? I have scanned the pc over and over ??? and everything seems good ??

Malware is a possibility (especially with the high CPU usage) but I think it's unlikely.

[sum_guy]

That is extremely high cpu utilization, I concur with jagabo, since you have nothing to lose, why not try downloading malwarebytes and running a complete scan, maybe something is running in the background that is killing performance? Traditional viruses are not the problem they once were, but malware is rampant. I wouldn't download this from anywhere but the source...

[Johnnysh]

thank you

I am doing a scan right now from malwarebytes, thanks for the suggestion

for many years I have had a feeling that all my machines have lacked Performance and I have never been able to get to the bottom of it

I have wiped windows so many times, formatted hard drives, even Kill Disked drives, fdisk and so on

A month ago I even purchased and Intel I7 2.8ghz with 6gig of DDR3 ! and still having problems with that machine !

I think this video fault is just visually showing some thing much deeper in the way of a problem that I have lived with for many years !

By you guys informing me my CPU usage is high has now lead me to thinking something is quite wrong somewhere

The only problem I have had over the years is nothing ever finds any spyware etc. the machines are always show as clean ??

It may be something thats hiding on the hard drive before windows even loads ?? so it has windows in it control i.e. controlling the windows kernels

Could it even be somthing more clever than rootkits or spyware, may be something custom written to cause problems ?? that undetectable ? I don't want to start getting paranoid but this is all crazy,,,,

Could this be a hardware virus (Cmos / bios / Harddrive / Video Card) thus why nothing ever detects it in windows, I may be sounding a little bit extreeme


And whats really strange is we have now gone round in a full circle, from a video fault back to what I started this topic off on "A real strange problem ripping Virus or is it me" !!!


Umm

not sure


all I know is for as long as I can remember I have had video problems


when playing black.mpg my system idle is 67 / 54 % using VLC Player


here is the spec of this machine, though not the fastest processor !!






thanks for you advice




Nothing nasty showing ??

Antivirus programs could be a problem -- if it's scanning every byte of the video while it's being played.

[Johnnysh]

Ok

I will now remove this antivirus software on this machine and test again processor idle %

thanks

[jagabo]

AV software usually lets you specify what types of files are scanned.

[Johnnysh]

Ok I have removed it

I now have no anti virus software on this pc at all, not that anything previously flagged any viruses anywhere

I have run the test again using VLC playing my black.mpg file (black eyed peas) video clip



this still does not look good ?






Here is the tasks when running the same video file in windows media player

[jagabo]

So you're now seeing VLC using about 30 percent CPU and no other programs are using any significant amount? That looks about right. You're still getting jerky playback? This won't fix tearing.

[Johnnysh]

Yes

VLC is using about 30% and still get the tearing problem

Yes still getting Jerky playback

And yes still getting tearing ??

I will post results using your test files to, this playing bff.mpg (I think its much less due to the video being not so complicated and no sound ?)







here is exactly the tear effect I see in the VLC player

http://www.megaupload.com/?d=JX68XL0H

[jagabo]

I didn't see any tearing in that sample video. Tearing looks like the image in this post:

https://forum.videohelp.com/threads/313687-video-wrinkles?p=1939257&viewfull=1#post1939257

But if you are having problems with tearing in a MPG file you're probably having it with other types of videos too. What graphics card is in your computer? Have you updated it to the latest WHQL certified drivers? The fact that WMP and VLC are having similar problems hints that the driver is at fault.

My Win7 computer is running an old dual core AMD 3800 CPU and an ATI Radeon 4850 graphics card. I get no tearing there. CPU usage runs 5 to 10 percent using VLC to play my TFF/BFF files, about twice that with your Black Eyed Peas video.

[Johnnysh]

Hi


Looking at your link I have the same problem, tearing

I will be trying out a new video card later today

but at the momment I have an ATI x1950 video card in this system


One thing thats strange is I only seem to get the tearing on your two files, when I play black.mpg no tearing, just very jerky playback ?? but the jerky playback may be related to the tearing ??

Thanks for your reply

Just something to try assuming that the dvd doesn't have encryption. double click on the my computer icon and right click on the dvd drive with the disk in and select explore. double click on the video_ts folder and select view by type. Just copy one of the large VOB's to your desktop and doubleclick it to play. VLC should play it or rename the extension to .mpeg and it will play in any player. VOB are nothing more than mpg files with a a vob extension. See what result you get. Not much effort to see if the result is different. If not encrypted then there isn't any reason to re-encode to mpg. if still problematic, keep the file and open it in dvdshrink and see if the preview plays in reauthor mode. If it plays but won't in outside of dvdshrink then you have an codec issue. I only use the K-Lite packs for all of my clients.
