* hevc_mvs: avoid deriving tmvp in amvpChristophe Gisquet2014-08-121-1/+2
| | | | | | | | Reduces the number of calls to tmvp derivation from 933685 to 586271 on a sequence. Reviewed-by: Mickaël Raulet <mraulet@insa-rennes.fr> Signed-off-by: Anton Khirnov <anton@khirnov.net>
* hevc: wait proper position for tmvpChristophe Gisquet2014-08-121-1/+2
