[RFC] Monotonic clock usage in buffer timestamps

2011-11-01 Thread Laurent Pinchart
Hi everybody, The V4L2 specification documents the v4l2_buffer timestamp field as For input streams this is the system time (as returned by the gettimeofday() function) when the first data byte was captured. The system time is a pretty bad clock source to timestamp buffers, as it can jump
