Comment 1 Du Yan 2012-10-18 07:27:22 UTC 
when using mplayer for decoding, it works well.

And the GPU hang issue can be reproduced with the below files: CAPA1_TOSHIBA_B.264
CVWP3_TOSHIBA_E/CVWP3_TOSHIBA_E.264

From the trace log it seems that the CAFI1_SVA_C.264 video stream is based on the interlaced format. It seems that the support of interlace is not very well in gst-vaapi.

Hi, Feng
    Will you please add some comment about this bug?

Thanks.

This video stream is based on the interlaced format, which is not supported in gst-vaapi.

At the same time as it can't be reproduced on the latest kernel/ubuntu 12.04 kernel, this priority of this bug is downgraded.

Thanks.
