As an added bonus we usually get PresentationTime set for + each frame, so we can expand on this later for smarter latency + reporting (by looking at the diff between the timestamp from the + driver and the time according to the GStreamer clock). + Use an internal worker thread for opening the device, setting caps, + changing its state and closing it. This way we're a lot more + compatible with drivers that rely on hacks to do video-effects + between the low-level NT API and the application. Ick. + Start the ks clock and set the pin to KSSTATE_RUN on the first + create() so that we'll hopefully get hold of the GStreamer clock + from the very beginning. This way there's no chance that the + timestamps will make a sudden jump in the beginning of the stream + when we're running with a clock. + * sys/winks/kshelpers.c (CHECK_OPTIONS_FLAG, + ks_options_flags_to_string): + Reorder the flags to match the headerfile order, and make the string + a bit more compact. + * sys/winks/ksvideohelpers.c (ks_video_probe_filter_for_caps): + Avoid leaking KSPROPERTY_PIN_DATARANGES. + 2008-09-09 Mark Nauwelaerts <mark.nauwelaerts@collabora.co.uk> * configure.ac: |
