Changing the location property on filesrc about gstd-1.x

[michaelgruner]

Those exact commands work for me. You are only allowed to change a filesrc location in the NULL state. The pipe is in the NULL state when it's created by gstd, so you should be able to change it just fine. Here's my output:

mgruner$ gstd-client pipeline_create testpipe filesrc name=src location=/path/file1.mp4 ! fakesink
{
  "code" : 0,
  "description" : "Success",
  "response" : {
    "properties" : [
        {
            "name" : "name",
            "value" : "\"testpipe\"",
            "param" : {
                "description" : "The name of the current Gstd session",
                "type" : "gchararray",
                "access" : "((GstdParamFlags) READ | 234)"
            }
        },
        {
            "name" : "description",
            "value" : "\"filesrc name=src location=/path/file1.mp4 ! fakesink\"",
            "param" : {
                "description" : "The gst-launch like pipeline description",
                "type" : "gchararray",
                "access" : "((GstdParamFlags) READ | 234)"
            }
        },
        {
            "name" : "elements",
            "value" : "((GstdList*) 0x7fb085038310)",
            "param" : {
                "description" : "The elements in the pipeline",
                "type" : "GstdList",
                "access" : "((GstdParamFlags) READ | 224)"
            }
        },
        {
            "name" : "bus",
            "value" : "((GstdPipelineBus*) 0x7fb085039b20)",
            "param" : {
                "description" : "The bus callback for this element",
                "type" : "GstdPipelineBus",
                "access" : "((GstdParamFlags) READ | 224)"
            }
        },
        {
            "name" : "state",
            "value" : "((GstdState*) 0x7fb085039880)",
            "param" : {
                "description" : "The state of the pipeline",
                "type" : "GstdState",
                "access" : "((GstdParamFlags) READ | UPDATE | 226)"
            }
        },
        {

            }
        }
    ]
}
}
