you can get this information from the name of output pin of the Elecard MPEG Push Demultiplexer filter. But it is a new feature and it is available in SDK version 1.2. If you have an obsolete SDK version, please contact our sales(firstname.lastname@example.org
) for update.
Example of pin`s name: Audio (PID <number> @ Prog# <number>) lang: <code>
<code> - the language identifier (it is usually first three letters of language name). The code standard values are described at http://en.wikipedia.org/wiki/List_of_ISO_639-2_codes
If the audio stream doesn`t include information about language then the field 'lang' is absent.
