TagList.getSampleIndex

bool getSampleIndex(string tag, uint index, out gst.sample.Sample sample)

Gets the sample that is at the given index for the given tag in the given list and copies it into the variable pointed to by sample. Free the sample with gst_sample_unref() when it is no longer needed. You can retrieve the buffer from the sample using [gst.sample.Sample.getBuffer] and the associated caps (if any) with [gst.sample.Sample.getCaps].

Free-function: gst_sample_unref

Parameters

`tag`	tag to read out
`index`	number of entry to read out
`sample`	address of a GstSample pointer variable to store the result into

Returns

true, if a sample was copied, false if the tag didn't exist in the

given list or if it was null.
