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). Fixes trac issue #1092. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	181b2c3724	avcodec/mjpegenc: disallow encoding amv with height%16!=0 I do not know on which side to place the padding to encode with 16x16 MBs If someone knows or has a known to be correct sample, please contact me Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago

Michael Niedermayer	6005ab3e0e	avcodec/mjpegenc: use av_log2_16bit() in encode_block() This reduces the number of operations done per non zero coefficient Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
