1. gstreamer 播放音频
command: gst-launch-1.0 filesrc location=./qqqg.wav ! wavparse ! alsasink
2. gstreamer 播放网络流
gst-launch-1.0 playbin uri=http://10.168.6.99:7000/R*0*
3. build a pipeline automatically
pipeline = gst_parse_launch ("playbin uri=https://www.freedesktop.org/software/gstreamer-sdk/data/media/sintel_trailer-480p.webm", NULL);
4. build a pipeline manually 相当于3
GstElement *pipeline, *source, *sink;
source = gst_element_factory_make ("videotestsrc", "source");
sink = gst_element_factory_make ("autovideosink", "sink");
pipeline = gst_pipeline_new ("test-pipeline");
gst_bin_add_many (GST_BIN (pipeline), source, sink, NULL);
gst_element_link (source, sink) != TRUE);
g_object_set (source, "pattern", 0, NULL);
5. 播发音频:gst-launch-1.0 filesrc location=hama.mp4 ! qtdemux name=demuxer demuxer. ! avdec_aac ! audioconvert ! audioresample ! alsasink (audioresample可选)
6.播放mp4文件:gst-launch-1.0.exe playbin uri=file:///F:\\hama.mp4
7.gst-launch-1.0 filesrc location=hama.mp4 ! decodebin ! autovideosink
