Hi all,
I would like to know how to change/set the aspect ratio of an already encoded mpeg2 stream (unencrypted). Is there some tool that can do that?
I'm using flaskMpeg with the LSX plugin to encode my mpg2's. The thing is that LSX doesn't set any aspect ratio flag or whatever it is, it just takes whatever it gets. In flask you can check 'Keep aspect ratio', in my case the original AR is usually 16:9, but unfortunately in that case it sends the frames with black-bars to compensate for the aspect ratio to LSX which willingly encodes those too. When I uncheck 'Keep Aspect Ratio' in flask, only the actual data gets encoded, but without the aspect ratio data, the player, mostly PowerDVD, obviously doesn't know how to render it correctly.
I usually encode at high quality with AC3. I also use bbmpeg, virtualdub, avisynth, well, the usual stuff, but couldn't find a solution.
Many thanks for your help!

[I'm not really concerned with any flask setting.
Rather I'd like to know how to change the aspect ratio of any given Mpeg2 stream. I think that it maybe is just a flag, maybe all over the stream, I don't know. Maybe it isn't possible without lengthy recompile. Generally, it's more a LSX problem than flask related. And I'm not so sure if I qualify for customer support]
