Some formats contain aspect info, others don't, and some might be limited in what aspect ratios they can describe. You need to ensure that you are using a container/codec which can contain the aspect ratio you want to use. I'd reccomend reading up on the different video formats, and then try one of them which supports what you need. libav *should* preserve the sample_aspect_ratio value if possible. If it doesn't, and the format supports it, report it as a bug. -- Michael Conrad IntelliTree Solutions llc. 513-552-6362 [EMAIL PROTECTED] _______________________________________________ libav-user mailing list [email protected] https://lists.mplayerhq.hu/mailman/listinfo/libav-user
