So, I spend few hours trying to incorporate the partial change. I'm not sure that the video sent by <jamrial> earlier follows the faces order here https://github.com/google/spatial-media/blob/master/docs/spherical-video-v2-rfc.md#semantics-3
Because when I made this change, I got a reasonable equirectangular ouput: https://imgur.com/a/BEN00 comparing to the changes sent earlier. https://imgur.com/a/vaIvW diff --git a/libavfilter/vf_panorama.c b/libavfilter/vf_panorama.c index de08ef4..5383d57 100644 --- a/libavfilter/vf_panorama.c +++ b/libavfilter/vf_panorama.c @@ -34,12 +34,12 @@ enum Projections { }; enum Faces { + DOWN, LEFT, + TOP, FRONT, RIGHT, - TOP, BACK, - DOWN, }; struct XYRemap { @@ -403,7 +403,7 @@ static int config_output(AVFilterLink *outlink) switch (face) { case LEFT: - locate(z, x, y, M_PI, rw, rh, &ox, &oy); + locate(z, x, y, -M_PI_2, rw, rh, &ox, &oy); break; case FRONT: locate(x, z, y, 0., rw, rh, &ox, &oy); @@ -418,7 +418,7 @@ static int config_output(AVFilterLink *outlink) locate(x, y, z,-M_PI_2, rw, rh, &ox, &oy); break; case DOWN: - locate(y, x, z,-M_PI_2, rw, rh, &ox, &oy); + locate(y, x, z, M_PI_2, rw, rh, &ox, &oy); break; } What I'm saying is: when I changed face order to this (which video sample seems to follow), I got a reasonable output. down | left | top front | right | back Comparing to Google's: right | left | top down | front | back _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
