[MPlayer-dev-eng] [PATCH 2/2] playback_speed limits: MP_CMD_SPEED_*

[Robert Juliano]

Patch 2: prevent non-positive playback_speed

While -speed and mp_property_playback_speed clamp playback_speed,
MP_CMD_SPEED_* didn't.  Ex. with input.conf "[ speed_incr -0.1",
playback_speed could still become non-positive.
