To my understanding, EAC is just a special case of cubemap, which should consist of six square faces. Apparently, that is not the case for this output. Can anyone help me understand why the output EAC texture does not have square faces as in regular cubemaps? Thank you! you can overwrite the default output size with the w and h options: v360=e:eac:w=3000:h=2000 Michael ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
