Currently -they are returned with a PTS of 0 because they aren't associated -with a timestamped frame to encode. These are handled by either -returning the timestamp of the last buffer to have been received, -or in the case of the first buffer the timestamp taken at -start_streaming. -This results in a race where the current frame may have started -before we take the start time, which results in the first encoded -frame having an earlier timestamp than the header bytes. - -Ensure that we never return a negative delta to the user by checking -against the previous timestamp. - -Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.org> ---- - .../staging/vc04_services/bcm2835-camera/bcm2835-camera.c | 5 +++++ - 1 file changed, 5 insertions(+) - ---- a/drivers/staging/vc04_services/bcm2835-camera/bcm2835-camera.c -+++ b/drivers/staging/vc04_services/bcm2835-camera/bcm2835-camera.c -@@ -393,6 +393,11 @@ static void buffer_cb(struct vchiq_mmal_ - ktime_to_ns(dev->capture.kernel_start_ts), - dev->capture.vc_start_timestamp, pts, - ktime_to_ns(timestamp)); -+ if (timestamp < dev->capture.last_timestamp) { -+ v4l2_dbg(1, bcm2835_v4l2_debug, &dev->v4l2_dev, -+ "Negative delta - using last time\n"); -+ timestamp = dev->capture.last_timestamp; -+ } - buf->vb.vb2_buf.timestamp = ktime_to_ns(timestamp); - } else { - if (dev->capture.last_timestamp) { |
