07-30 12:21:07.795   364   489 E FrameDecoder: failed to get video frame (err -1010)
From the log, we find the testcase is related with colorformat.

Bug #117044023

[root cause]:
1. we can get below information from source code:
OMX_COLOR_FormatYUV420SemiPlanar = 0x00000015 ;
OMX_COLOR_Format32BitRGBA8888 = 0x7f00a000;
“ MediaMetadataRetrieverTest#testGetFrameAtIndex” cts  case requires the color format of the frame data to be OMX_COLOR_Format32BitRGBA8888 color format.
Frameworks\av\media\libstagefright\colorconversion\ColorConverter.cpp ：
bool ColorConverter::isValid() const {
……
 case OMX_COLOR_FormatYUV420Planar:
            return mDstFormat == OMX_COLOR_Format16bitRGB565
                    || mDstFormat == OMX_COLOR_Format32BitRGBA8888
                    || mDstFormat == OMX_COLOR_Format32bitBGRA8888;
case OMX_COLOR_FormatYUV420SemiPlanar:
        case OMX_TI_COLOR_FormatYUV420PackedSemiPlanar:
            return mDstFormat == OMX_COLOR_Format16bitRGB565;
……}
ColorConverter does not support color format conversion from OMX_COLOR_FormatYUV420SemiPlanar to OMX_COLOR_Format32BitRGBA8888.

 2. The input data of this case should be OMX_COLOR_Format32BitRGBA8888 color format, and the ColorConverter in frameworks only support color format conversion from OMX_COLOR_FormatYUV420Planar to OMX_COLOR_Format32BitRGBA8888, does not support  from OMX_COLOR_FormatYUV420SemiPlanar to OMX_COLOR_Format32BitRGBA8888.
    But the video hardware decoder of Unisoc device can output YUV data with OMX_COLOR_FormatYUV420SemiPlanar color format, it can not output OMX_COLOR_FormatYUV420Planar color format. So this case failed.

[changes]:
Add a color conversion code to ColorConverter(Frameworks\av\media\libstagefright\colorconversion\ColorConverter.cpp, the patch is listed below). Enable ColorConverter to support color conversion from OMX_COLOR_FormatYUV420SemiPlanar to OMX_COLOR_Format32BitRGBA8888.
Because the hardware decoder of Spreadtrum phone does not support OMX_COLOR_FormatYUV420Planar. we need the ColorConverter in frameworks support color format conversion from OMX_COLOR_FormatYUV420SemiPlanar to OMX_COLOR_Format32BitRGBA8888.
    We will request to waive for this. Could you help us or give us a waiver? Thanks a lot.
