How to change video source in Amazon kinesis_video_gstreamer_sample_app.cpp?

问题

I am running kinesis_video_gstreamer_sample_app.cpp on MacOS and it streams to AWS Kinesis from FaceTime (iSight) camera. How can I switch the video source to a USB Webcam? Thanks :)

Ok, I figured it out finally, modify the file kinesis_video_gstreamer_sample_app.cpp as follows.

Change:

if (data.encoder) {
    data.source = gst_element_factory_make("autovideosrc", "source");

To:

if (data.encoder) {
    data.source = gst_element_factory_make("avfvideosrc", "source");
    g_object_set(G_OBJECT(data.source), "do-timestamp", TRUE, "device-index", 1, NULL);
