Marker In, Marker Out. Only play a part in a video

[Kev]

Hi,

I would like to know if it possible to set a marker in and marker out, to be able to play only a part of a video. Is there a command to set a start of a video ?

And if it possible, which will be the accuracie of the markers, second or frame ?

If it's not. What is the reason, it couldn't be done ?
And do you think it could be developped ?

Thank

You already have Bookmarks in the wxWidgets interface. I don't know if that's what you're talking about. It sure is far from perfect but it should at least work

In fact, what I want to do is : only take a part of a video, like that I will ba able to make a video from a lot of small part. But what I understand is that VLC have only a second accuracy. I would something more accurate, like frame or maybe millisecond (ms) to be able to cut the video where I want.

The other thing I want to do is to take only one frame of the video to be able to use it as a keyframe of the video.

I tryed the Bookmarks, but i had some trouble in using it. It seems to doesn't exporte well some time.

i'm trying to understand why VLC can not do frames by frames like some other player does.
I know for exmple that MPlayer is able to do it. So why VLC can't, Aren't they use tthe same librarie ?

Is somebody can explain me why it's not possible ? And do you think it could be done by doing some developpement ?

If you prefer you can explain it in french, it's up to you.

It can't because it does work the same way, since it was designed as a network stream client. The only part of VLC that knows what a frame is is the rendering part, which is at the end of the processing chain.

Thanks, Dionoea. Is there some where I can find how vlc do the playing part ? I would like to get more information about it.

edit :
If I understand well. The fact we are limited in second is due to the API, But under, VLC is using nanosecond. So by using MediaControlAPI, or a new one, I should be able to get more accurate.
