Error info:
---------------------
This video only has 60 frames, but we get 65 or more frames while decoding.

Reproduce steps:
---------------------
1.xinit&
2.mplayer -vo vaapi -va vaapi MR7_BT_B.h264

Comment 1 cc 2012-11-27 00:19:01 UTC

Do something correct:

The video "MR7_BT_B.h264" has 59 Frames by reference, (The detail info: resolution: 192*128, chroma format:4:2:0, YUV filesize: 2899968)

The decoding output video file only has 45 frames by our driver, (The detail info: resolution: 192*128, chroma format:4:2:0, YUV filesize: 2211840)

1. Test with the latest driver and MR7_BT_B.h264 decoding is passed now.

2. sp1_bt_a.h264 and sp2_bt_b.h264 decoding failed. they can playback well with no frames lossing. but compare with software decoding, the decoding quality is too poor.

Comment 3 Du Yan 2012-11-29 02:50:35 UTC

compare with the sp1_bt_a.h264/sp2_bt_b.h264 yuv refererencefile which download from ITU we get below result:
