The VideoLAN Forums

I hope anyone can help. we are having a bad problem with video on the Mac. Quicktime player works fine BTW. The video is garbled and tiny. Please see the link below to the image of what the problem looks like. Any help would be great. This is driving us nuts!

Is this video from a local file, or incoming from a stream, or live from a capture device?

Version of MacOS?

It doesn't matter. The picture is of a Windows media file being played locally. But it also causes the same problem with multicasts and other network streams.

As you might know, VLC uses the FFMPEG library for decoding the most video- and audio tracks. Since Microsoft did not publish any details on its WMV codecs, the WMV2-codec you probably tried to use is quite buggy. There isn't much you can do to improve the video except to help the FFMPEG-project to create a better one.

The windows-port of VLC can display these videos fine, because it uses a MS-framework (which is Win32 only of course) to display them instead of FFMPEG.

I wish hat was the only problem. We have a capture card that outputs an MPEG-4 stream that can be received using RTSP. In the Quicktime player it works great. In VLC you get the same error that you saw with the WMV file. That was just for an example. I am doing no transcoding. Just selecting Play locally with an MPEG-TS or PS stream. Same problem.

Well, this kind of file plays usually fine at my side so your reported behaviour is kind of strange. Feel free to upload us a sample to ftp://ftp.videolan.org/incoming/ and post the specific name here so we can have a look at it.

Btw. Do you use a self-compiled variant of VLC for these tests or an official, by our team created build?
