Author	SHA1	Message	Date
Petru Rares Sincraian	124526ba1a	Added a selftest to libavutil/display.c ... - Check if av_display_rotation_get() gets the correct degrees - Check if av_display_rotation_set() sets the correct matrix - Check if av_display_matrix_flip() changes correct the matrix Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
Vittorio Giovara	e4fe535d12	mov: Write the display matrix in order ... This will allow to copy the matrix as is and it is just cleaner to keep the matrix in the same order specified by the mov standard (which is also explicitly described in the documentation). In order to preserve compatibility, flip the angle sign in the display API av_display_rotation_set() and av_display_rotation_get(), and improve the documentation mentioning the rotation direction.	10 years ago
Vittorio Giovara	a54f03bf07	display: add matrix flip api	11 years ago
Clément Bœsch	fa972dcf1a	avutil/display: use hypot().	11 years ago
Martin Storsjö	82fc9f4b38	display: Include mathematics.h for fallback definition of NAN ... This fixes compilation with MSVC. Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Vittorio Giovara	bddd8cbf68	Add transformation matrix API. ... Add AV_PKT_DATA_DISPLAYMATRIX and AV_FRAME_DATA_DISPLAYMATRIX as stream and frame side data (respectively) to describe a display transformation matrix for linear transformation operations on the decoded video. Add functions to easily extract a rotation angle from a matrix and conversely to setup a matrix for a given rotation angle. Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago
