Comment (by juha-h):
I installed mobile-ffmpeg and used it to record video from android_camera
like this:
ffmpeg -video_size hd720 -f android_camera -i 0 -camera_index 1 -r 10 -t 5
-y <path>
Resulting video always has this side data no matter in which position I
hold the device:
Input #0, android_camera, from '0':
Stream #0:0: Video: rawvideo (NV21 / 0x3132564E), nv21, 1280x720, 30 fps,
30 tbr, 1000000000.00 tbn, 1000000000.00 tbc
05-13 18:59:41.746 18715 18715 I Baresip : Side data:
05-13 18:59:41.746 18715 18715 I Baresip : displaymatrix: rotation
of -90.00 degrees
I haven't yet figured out how I can set android_camera
add_display_matrix() function ctx->sensor_orientation value from a CLI
option.
Suggestions on how to test this issue using ffmpeg CLI options would be
appreciated.
