Steps to reproduce:

Steps to reproduce:
  
   Prebuild condition:1000 pictures,200 videos and 164 muisic are stored in the external SD.

1、play a video in  the external SD,and click the "fast forward" key and then click the "fast backward" key;

2、record the response time of  the "fast forward" key  and the "fast backward" key;

3、play a music in the  the external SD,and click the "next" key;

4、record the response time of  the "play" key  and the "next" key;

Lecky, please retest this against 1.2 and post your findings as you did in comment 0.

Hi, Mike,


    We only want to improve the performance in build v1.1.

For music app, fast-forward/rewind were not supported until bug 897882 was landed, it's a v1.2 feature to support AVRCP so I think we are not talking about fast-forward/rewind here, also, for video app there is no such feature because no next/previous buttons for the playing controls.

Lecky, are you talking about the seeking on the duration slider?
