Title: Video player feedback
Post by: ubacher on September 22, 2023, 11:54:06 AM
The left /right 5 second jump:
When jumping left which results in a negative time it goes to a very large number.
At times it hangs there.
The jump does not seem to be 5 seconds - somewhat random.

When it stops at the end the jump back 5 secs does not work.

Several more unexplained behaviour.

I can confirm this behaviour.

You jump how? Keyboard or toolbar icons?
If you look at the time display, how far does it jump?
Note that, depending on the video format and availability of key frames in the video, Windows Media Foundation may not be able to jump precisely. Upload a sample video that exhibits this behavior.
A screen shot of the video player does not help much.

Jumping via toolbar icons
each jump is around 10 sec
tested with mp4 and mov files
mts files seems not to be supported

IMatch tells Windows Media foundation to seek 5000 ms when you click the button or use the cursor keys.
What Media Foundation makes of that is outside of my control. Maybe key frames are not available or something else.
Media Foundation media seeking is pretty much a black box. IMatch tells is to go 5 seconds in that direction and that's it. Then IMatch waits for the seek finished event to update the video player UI.

This can very well be the case. IMatch can only support what Windows Media Foundation supports:

Either put the video into another container or use something like VideoLan to play it.

Not a big problem, at least for me, only very view mts files.

This was correct. Using the cursor keys jumped 5s, using the ribbon 10s.
I've now set it to use 5s for both ways.
