Michael Niedermayer	068026b0f7	avcodec/mjpegenc_common: Store approximate aspect if exact cannot be stored Fixes Ticket5244 Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
Vittorio Giovara	2862b63783	lavc: Move prediction_method to codec private options This options is only used by huffyuv, ffvhuv, jpegls, mjpeg, mpegvideoenc, png, utvideo. It is a very codec-specific options, so deprecate the global variant. Set proper limits to the maximum allowed values, and update utvideoenc tests to use the new option name.

Carl Eugen Hoyos	d6cfbcd621	lavc/mjpegenc: Add an option to force outputting chroma matrix. RFC 2435 suggests that mjpeg over rtp uses both two tables.	9 years ago

Michael Niedermayer	d41a4a765b	avcodec/mjpegenc: allow encoding amv with height % 16 != 0 when strict -1 is set This should make it simpler for users to test if such videos work Suggested-by: carl Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Reimar Döffinger	6d695d7acc	Fix nonsense non-mod16 AMV flipping code. It is obviously nonsense since it produces wrong results or even crashes (crashes should be encode-only though).
