		# <a name="ColorConversion"></a> Fuzzer for Colorconversion

		ColorConversion supports the following parameters:
		1. SrcColorFormatType (parameter name: "kSrcFormatType")
		2. DstColorFormatType (parameter name: "kDstFormatType")

		\| Parameter\| Valid Values\| Configured Value\|
		\|------------- \|-------------\| ----- \|
		\|`kSrcFormatType`\| 0. `OMX_COLOR_FormatYUV420Planar`<br/>1. `OMX_COLOR_FormatYUV420Planar16`<br/>2. `OMX_COLOR_FormatYUV420SemiPlanar` <br/>3. `OMX_TI_COLOR_FormatYUV420PackedSemiPlanar` <br/>4.`OMX_COLOR_FormatCbYCrY`<br/>5.`OMX_QCOM_COLOR_FormatYVU420SemiPlanar`<br/>6.`COLOR_FormatYUVP010`\|Value obtained from FuzzedDataProvider\|
		\|`kDstFormatType`\| 0. `OMX_COLOR_Format16bitRGB565`<br/>1. `OMX_COLOR_Format32BitRGBA8888`<br/>2. `OMX_COLOR_Format32bitBGRA8888` <br/>3. `OMX_COLOR_Format16bitRGB565` <br/>4. `OMX_COLOR_Format32bitBGRA8888`<br/>5.`OMX_COLOR_FormatYUV444Y410`<br/>6. `COLOR_Format32bitABGR2101010`\|Value obtained from FuzzedDataProvider\|


		#### Steps to run
		1. Build the fuzzer
		```
		$ mm -j$(nproc) color_conversion_fuzzer
		```
		2. Run on device
		```
		$ adb sync data
		$ adb shell /data/fuzz/arm64/color_conversion_fuzzer/color_conversion_fuzzer
		```
