how to get sar (sample aspect ratio) of current stream?

[ikarus76]

hi community!

does anyone know, how i can get the sample aspect ratio parameter (sar) of the current stream? (using libvlc with version 1.0.1)

my problem is the following:
i use vlc for watching iptv. if the stream changes the aspect ratio, the picture gets streched, because the aspect ratio does not change "on the fly". I need to restart the stream or change the channel. in the debug messages of vlc i can see the used sar for the stream. i need to get this information from the stream, to dynamically change the ratio...

any hints?

best regards,
michael

I do it in my program. In the positionchanged event, i check the video size reported by libvlc, and if the ratio doesn't match the ratio of the window, my program resize itself.

I have tried this.

The problem is, that I have a continous stream. The stream occasionally changes video size and aspect ratio, but vlc doesn't recognize it. if i reconnect to the stream, the video size is reported correctly. if i periodically check the video size, it's always the same. what i mean is, that vlc doesn't update the video size during receiving a stream...

The last time i had such a stream (a tv stream from my provider), it was working. Now the stream has changed and has always a 16/9 ratio, so i can't check again.
Maybe it's broken in 1.0.1 ....

i have tried now with different versions (0.9.8a, 1.0.0, 1.0.1) and no one gave me a aspect ratio...

I get the video size, but this always keeps the same size. Also the original VideoLan Client doesn't check, if the sample aspect ratio has changed...

Maybe in my case, the video size was really changing over time, and not the aspect ratio.
