问题 I'm playing a transport stream file (*.ts) using the following pipeline: gst-launch-0.10 playbin2 uri=file:///c:/bbb.ts But I need to convert that into a pipeline myself. I'm not sure how to achieve this. So far I have tried: (works fine) gst-launch-0.10 -v filesrc location=c:/bbb.ts ! tsdemux ! audio/x-ac3 ! fakesink But if i replace fakesink with autoaudiosink it fails with a not-linked error. And even the fakesink doesn't work for video: gst-launch-0.10 -v filesrc location=c:/bbb.ts !

What is the sequence to be followed to play a song using gstreramer?

问题 I am building a music player based on gstreamer-0.10. I am able to play the successfully , but I have issues when I change the state of the pipeline. I have posted the code to initialize and start the pipeline below : void start_gstreamer() { gst_init(0,NULL);//call to initialise gstreamer time_val=0;//set to default value volume = 1.0;//set volume to default value player = gst_element_factory_make ("playbin2", "player");//get pipeline equalizer = gst_element_factory_make ("equalizer-10bands"
