libuvc_cam : issue about running the driver
I have follow the instructions in libuvc_camera, run the launch file as
<node pkg="libuvc_camera" type="camera_node" name="usb_cam">
<!-- Parameters used to find the camera -->
<param name="vendor" value="0x199e"/>
<param name="product" value="0x8302"/>
<param name="serial" value="3"/>
<!-- If the above parameters aren't unique, choose the first match: -->
<param name="index" value="0"/>
<!-- Image size and type -->
<param name="width" value="640"/>
<param name="height" value="480"/>
<!-- choose whichever uncompressed format the camera supports: -->
<param name="video_mode" value="uncompressed"/>
<param name="frame_rate" value="60"/>
<param name="timestamp_method" value="start"/>
<param name="camera_info_url" value="file:///.../*.yaml"/>
<param name="auto_exposure" value="1"/> <!-- use aperture_priority auto exposure -->
<param name="auto_white_balance" value="false"/>
</node>
the terminal came out the following information at last few lines :
unsupported descriptor subtype: 13 uvc_get_stream_ctrl_format_size: Invalid mode (-51) and process has died
Does any body could provide any clue to solve this issue? Thank you very much.
