Six months later and I have now found a way to correct the aspect ratio without transcoding and losing quality. Apparently it can't be done in VLC. But the program MP4Box does it perfectly. MP4Box is a command line tool specifically for packaging and unpackaging container formats. That's all it does...

Bump. Anyone else noticed this?

Hi. I just upgraded to V2.1.3 and the button that allowed you to configure a Direct Show device has disappeared. It used to be on the tab for 'Open capture device'. Now it's not there. So how can you configure a Direct Show device now? I am trying to stream my desktop using the Unreal Screen Capture...

Hi. Can anyone help me with this aspect ratio conversion problem? I have a recording which is in the wrong aspect ratio. It's 720x576 and should be displayed in widescreen 16:9. Due to some mix-up at the encoding stage it is wrongly identified as 4:3. So when I play it in VLC it appears squashed by ...

Thanks J-B. So what key is it ??????

Hi j-b. I don't know the correct syntax to include the aspect ratio inside the transcode. I tried this but it didn't work. vlc "vts_01_0.vob" --sout "#transcode{vcodec=mp2v,aspect-ratio=16:9}:std{access=file,mux=ps,dst="vlcfile.mpg"}" This gave an error in the message w...

After some problems with the command line on Windows I'm finally ready to start transcoding. But I can't get the aspect-ratio option to work. I have some files that are badly encoded with the wrong AR. If I play them in VLC the picture is all squashed. It's easy to change this in the GUI. Select 16:...

Hi VLC_help. Thanks for the tip to remove whitespace. Same as before, this only works if you change the single quotes to double quotes.

With single quotes Vista mangles the command line and VLC can't understand it. I've now got another problem with aspect ratio. I'll make a new thread. Thanks.

Thanks for your help j-b. I think I have nearly solved the problem. It looks like Windows completely mangles the command line when it passes the parameters to VLC. VLC was trying to use a filename of "vlcfile.mpg}'" as the input file (see below). That is actually part of the output file na...

Hi j-b. Thanks for the quick reply. I tried again and the messages window is completely blank. The modules window shows something like this but I think it's quite standard ... libvlc "libvlc"... playlist ... playlist fetcher ... interface "hotkeys" ... interface "globalhotke...

Hi. I've been unable to run transcode successfully from the command line. I've tried all day with different options. Whatever I do there is no output file created. I must be doing something silly. This is one of many commands I tried ... vlc -vvv "vts_01_0.vob" --sout='#transcode{vcodec=mp...
