How do I properly reduce the resolution of a 360 video using ffmpeg ?
10 avril 2017, par user3799235I have tried reduction with the following technique from a scale of
2048:1024with something like :ffmpeg -i eagle360half.mp4 -vf scale=1024:512 video360_1024.mp4however the playback then becomes warped and warbly (visually similar to a bad vhs tape). I can only speculate that this has something to do with the meridians and equirectangular projections. How would I properly scale/ reduce resolution of a 360 video usingffmpeg, or is this possible with some other cli tool ?Here is the output of mediainfo, ffmpeg, and then mediainfo again :
