<pre wrap="">Hello,
Following the question I asked last week on IRC :
I have a user of Vlc.DotNet that has an anamorphic video (4:3 image buffer
that should be displayed as 16:9) :
<a class="moz-txt-link-freetext" href="https://github.com/ZeBobo5/Vlc.DotNet/issues/386">https://github.com/ZeBobo5/Vlc.DotNet/issues/386</a>
The WPF control he's using uses libvlc_video_set_format_callbacks and
libvlc_video_set_callbacks to render the video, but it's displayed as 4:3 .
Here is the sample file:
<a class="moz-txt-link-freetext" href="https://github.com/ZeBobo5/Vlc.DotNet/files/1784317/AAA.zip">https://github.com/ZeBobo5/Vlc.DotNet/files/1784317/AAA.zip</a>
As per j-b suggestion, I used `libvlc_media_get_codec_description` to get
the description of the first Video track I found. The codec is "mpgv",
description : "MPEG-1/2 Video".
j-b also suggested that I could get the the video aspect ratio by getting
the video track. Is it safe to assume that there is only one video track?
Otherwise, how can I get the video track that is currently playing?</pre>

<span style=" color:#800080;">You may find which track is playing
from the </span><span style=" color:#800080;"><span style="
color:#800080;">libvlc_MediaPlayerESSelected event. on libvlcpp
you get this with onESAdded and onESSelected.<br>
<br>
So file formats do have many video tracks, the first one may not
even be the default one. So it's better to keep track of which
track (ID) is playing.<br>
