I'm trying to learn VLCKit，I would like to make a player based on this example：vlc-1.1/projects/macosx/framework/Examples

There are two problems:
1. I use a 768 * 480 video for test, when playing, vlc converted my size into 768 * 576. I think the reason is the "aspect-ratio" , so I want to convert to 16:10
2. When I use the under code

Code: Select all

- (IBAction)setAspectRadio:(id)sender {
    char * aspradio = (char *)[[sender title] UTF8String];    //16:10
    [player setVideoAspectRatio:aspradio] ;
}

to change the aspect-ratio to 16:10, but it's error...following is log

Code: Select all

[0x10182df10] main video output debug:new aspect-ratio 768:480, sample aspect-ratio 1:1
[0x10182df10] main video output debug:window size: 768x480
[0x10182df10] main video output debug:cropping picture 768x480 to 0,0,768x480
[0x10024f670] main generic error:Failed to change source AR

main generic error:Failed to change source AR

Please help me!

What does [player videoAspectRatio] return for your video?

What does [player videoAspectRatio] return for your video?

[player videoAspectRatio] : null
I had used different video files for test. so, I think it's none of videos business.
Thanks for your help.

Looks like a bug in libvlc then. You might want to try to the current code base, which will become VLC 1.2 to see if it is fixed (see the vlc-1.2.git repository). If not, you're regrettably on your own, since nobody is currently working on this part of VLC. Of course, you can file a ticket on trac.videolan.org, but there is no warranty to have this fixed in time..
