maximum allowed resolution, you can use this to limit the output video to that, while retaining the aspect ratio. For example, device A allows 1280x720 playback, and your video is 1920x800. Using this option (set it to decrease) and specifying 1280x720 to the command line makes the ou...
Changing the resolution of a video file will be one of the most common operations that we will perform when working with video files, and as such ffmpeg is able to do it perfectly. There are several reasons why we should want to change the resolution of a video file, for example:To ...

Previously we had calculated that we needed 278GB of storage to keep a video file with one hour at 720p resolution and 30fps. If we use YCbCr 4:2:0 we can cut this size in half (139 GB)* but it is still far from ideal. * we found this value by multiplying width, height, bits...
You may also add a .so link to .so.MAJOR, so that applications linked against .so are in fact linked to .so.MAJOR and thus ensures better binary compatibility as we take care not changing the MAJOR number until there is an incompatible ABI change. ...
