Currently ffmpeg doesn't have a parameter to maintain the aspect ratio of the original video given a certain height/width.

If you search around in the internet, this's a high demand feature, will be very useful if implemented.

This's a feature request, there's no output to place since this feature is missing.

Please reopen if you can provide an easy to reproduce testcase that shows why this is a desirable feature.

For e.g. we have a HD 1920x1080 p video which needs to be converted for a 320x280 mobile device using easy to use front ends like winff.

We need to maintain the aspect ratio in this case to ensure the video doesn't distort yet is playable in the small screen. For e.g. we wanna maintain the 320 px width and make the height variable.

Anyway, this bug should be closed cause the scale filter provides such a feature, I'll write about this in my blog.
