GStreamer 學習紀錄 gst-launch-1.0

利用 gst-launch-1.0 同時撥放影像和聲音

$ gst-launch-1.0 filesrc location="/opt/nvidia/deepstream/deepstream-5.0/samples/streams/sample_720p.mp4" ! qtdemux name=demux demux.audio_0 ! queue ! avdec_aac ! audioconvert ! alsasink demux.video_0 ! queue ! h264parse ! omxh264dec ! nveglglessink

使用 decodebin

$ gst-launch-1.0 filesrc location="/opt/nvidia/deepstream/deepstream-5.0/samples/streams/sample_720p.mp4" ! decodebin name=d d. ! nvvidconv ! nveglglessink d. ! queue ! audioconvert ! audioresample ! alsasink

$ gst-launch-1.0 filesrc location="/opt/nvidia/deepstream/deepstream-5.0/samples/streams/sample_720p.mp4" ! decodebin name=d d.src_0 ! nvvidconv ! nveglglessink d.src_1 ! queue ! audioconvert ! audioresample ! alsasink

使用 uridecodebin

nano@nano-desktop:~$ gst-launch-1.0 uridecodebin uri="file:///opt/nvidia/deepstream/deepstream-5.0/samples/streams/sample_720p.mp4" name=d d. ! nvvidconv ! nveglglessink d. ! queue ! audioconvert ! audioresample ! alsasink

只撥放影片

$ gst-launch-1.0 filesrc location="/opt/nvidia/deepstream/deepstream-5.0/samples/streams/sample_720p.mp4" ! decodebin name=d d.src_0 ! nvvidconv ! nveglglessink
