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 :

Quick stream from file which exists
4 mai 2017, par parsaI implement live streaming from mp4 video file which exists on the path with ffmpeg under hls format.
When my video file have the quality greater than hd720 , in encoding there are so many delays for creating .ts fragments.
I mean the .ts fragments slowly produced on my path,and because of it I have so many delays in showing the stream.
Here is my ffmpeg code for streaming :ffmpeg -re -i 123.mp4 -s cga -f hls -hls_list_size 0 -c:v libx264 -c:a aac 200p/out.m3u8
-s nhd -f hls -hls_list_size 0 -c:v libx264 -c:a aac 360p/out.m3u8
-s hd480 -f hls -hls_list_size 0 -c:v libx264 -c:a aac 480p/out.m3u8
-s hd720 -f hls -hls_list_size 0 -c:v libx264 -c:a aac 720p/out.m3u8
-s hd1080 -f hls -hls_list_size 0 -c:v libx264 -c:a aac 1080p/out.m3u8And here is the console output :
ffmpeg -re -i ../files/412-887123464/video/412-887123464.mp4 -s cga -f hls -hls_list_size 0 -c:v libx264 -c:a aac ../fil
