Slide show feature in VLC 1.0.0 not consistent

[s.g.]

Hi,

I am using VLC 1.0.0 to load a set of jpeg images into a playlist so I can view the images as an automatic slide show.
I set the Playlist option to "Repeat All".
When I press play. I expect each image to play for 10 seconds (as this is the value automatically set in the Playslist option called "Duration").
However, about 80% of the time, after the play bar has incremented by 10 seconds and has reached its end, the image will hang around for about another 10 seconds before switching to the next image in the list.
And at other times the switch from image1 to image 2 is almost immediate.
Each image that I tested was around 2048x2048.
I have tried this with VLC 1.0.1, as well as on two different Windows XP Machines.

In addition, I tried to use the command line to set the duration and file reload time, as follows:

vlc.exe --fake-duration=5000 (5000 is in ms)
vlc.exe --fake-file-reload=1 (1 is in sec)

But the duration of an image would never match up with the value I set.

Any suggestions as to how to get consistent image switching and playback when playing back images as a slide show?

[s.g.]

One more thing, I performed a similar test as above, except that the images were al 2048x1536 jpegs, running on a mac book pro, and there were no irregularities/timing issues.

It doesn't work with 2048x2048 but is ok with 2048x1536?

[s.g.]

It is still a problem with 2048x1536 images.
However, I did forget to mention that the problem occurs when Video Ouput is set to "OpenGL video output."
When Video Output is set to "Default", the Slide Show works as expected.
I am interested in the Slide Show feature when using OpenGL video output.

Thanks.

Does messages (Tools -> Messages... set Verbosity to 2) complain something when do slideshow with big pictures using OpenGL output?

[s.g.]

There are no error messages from Messages:

[VLC_help]

I don't see any OpenGL related errors, so I have no clue why this would happen with OpenGL video output.

[s.g.]

Ok, using VLC 1.0.1, I observe that images in a playlist (I tested with 4 images of 2048x2048 with the duration of each image set to be 10 seconds) still have long pauses between image switches.

This occurs with the Video Output set to either "Default" or "OpenGL Video Output".

I was watching the Message Logger, and right after an image has been displayed for 10 seconds, the logger says:

(1) EOF reached
(2) waiting decoder fifos to empty (this is repeated multiple times)
(3) finished input (this occurs right before the image switches to the next image)

So, during the extra stall time after an image has played its normal 10 second duration, it is stalling with the message in (2).

This message comes from src/input/input.c.

Any ideas how this can be remedied?

[VLC_help]

Decoder size was changed so hopefully it fixes the issue. But is just seems little odd that this would exist just with one VOUT.
