GstParse

Gst.ParseContext

Gst.ParseContext.prototype.new

function Gst.ParseContext.prototype.new(): {
    // javascript wrapper for 'gst_parse_context_new'
}

Allocates a parse context for use with Gst.prototype.parse_launch_full or Gst.prototype.parse_launchv_full.

Free-function: gst_parse_context_free

Gst.ParseContext.prototype.copy

function Gst.ParseContext.prototype.copy(): {
    // javascript wrapper for 'gst_parse_context_copy'
}

Copies the context.

Since : 1.12.1

Gst.ParseContext.prototype.free

function Gst.ParseContext.prototype.free(): {
    // javascript wrapper for 'gst_parse_context_free'
}

Frees a parse context previously allocated with Gst.ParseContext.prototype.new.

Gst.ParseContext.prototype.get_missing_elements

function Gst.ParseContext.prototype.get_missing_elements(): {
    // javascript wrapper for 'gst_parse_context_get_missing_elements'
}

Retrieve missing elements from a previous run of Gst.prototype.parse_launch_full or Gst.prototype.parse_launchv_full. Will only return results if an error code of Gst.ParseError.NO_SUCH_ELEMENT was returned.

Gst.prototype.parse_error_quark

function Gst.prototype.parse_error_quark(): {
    // javascript wrapper for 'gst_parse_error_quark'
}

Get the error quark used by the parsing subsystem.

Gst.prototype.parse_launch

function Gst.prototype.parse_launch(pipeline_description: String): {
    // javascript wrapper for 'gst_parse_launch'
}

Create a new pipeline based on command line syntax. Please note that you might get a return value that is not null even though the error is set. In this case there was a recoverable parsing error and you can try to play the pipeline.

To create a sub-pipeline (bin) for embedding into an existing pipeline use Gst.prototype.parse_bin_from_description.

Gst.prototype.parse_launch_full

function Gst.prototype.parse_launch_full(pipeline_description: String, context: Gst.ParseContext, flags: Gst.ParseFlags): {
    // javascript wrapper for 'gst_parse_launch_full'
}

Create a new pipeline based on command line syntax. Please note that you might get a return value that is not null even though the error is set. In this case there was a recoverable parsing error and you can try to play the pipeline.

To create a sub-pipeline (bin) for embedding into an existing pipeline use Gst.prototype.parse_bin_from_description_full.

Gst.prototype.parse_launchv

function Gst.prototype.parse_launchv(argv: [ String ]): {
    // javascript wrapper for 'gst_parse_launchv'
}

Create a new element based on command line syntax. error will contain an error message if an erroneous pipeline is specified. An error does not mean that the pipeline could not be constructed.

Gst.prototype.parse_launchv_full

function Gst.prototype.parse_launchv_full(argv: [ String ], context: Gst.ParseContext, flags: Gst.ParseFlags): {
    // javascript wrapper for 'gst_parse_launchv_full'
}

Create a new element based on command line syntax. error will contain an error message if an erroneous pipeline is specified. An error does not mean that the pipeline could not be constructed.
