does decodebin support to play video frame by frame?

[zhi]

hi guys,


does decodebin support to play video frame by frame?


i know that the playbin is able to do so, as described in link: 
https://gstreamer.freedesktop.org/documentation/tutorials/basic/playback-speed.html


however, i want to use decodebin to do so and cannot find a way to do so with gst_event_new_step, the launch statement is below:


data.pipeline = gst_parse_launch("filesrc location=f:/test001.avi ! avidemux name=demux ! decodebin name=decode ! videoconvert ! autovideosink name=videosink", NULL);


but how to get the equal "video_sink" in the pipeline?


thanks in advance
