Please ensure use USB 3.0 port and run with correct device index, e.g. ./sample/bin/camera 1

You could run <sdk>/tools/list_devices in the Terminal to see the indexes. See "/samples/README.md" to learn more.

About "corrupted data (0 bytes)", FFMpeg prints this information because that V4L2/the driver isn't clearing up properly after the capture.

• Code - FFmepg/v4l2.c, search "Dequeued v4l2 buffer contains corrupted data"
• Issue - Dequeued v4l2 buffer contains corrupted data (0 bytes)
• Patch - uvcvideo error on second capture from USB device, leading to V4L2_BUF_FLAG_ERROR

However, our SDK did not depend on FFMpeg on Linux since 1.6.
