We have licenses for your IPTV product for use in Hong Kong.
An important requirement of our customer is the ability to choose been three possible closed caption sub-streams in MPEG4 stream available off air at the hospital.
We note that you have Boolean (Yes/No) flags for switching closed captions on and off but we haven’t come across an obvious API for selecting between the possible streams.
As an example, we have posted a sample captured off air in Hong Kong at: http://www.oneviewservices.com/SubTitleTest.mpg
) reports the sub-streams for this file in the screen grab attached below which shows streams for subtitles in the Languages: Chinese, English and CHS (Simplified Chinese)
We notice that you may not have supported multiple alternative subtitles in the past:http://www.elecard.com/forum/index.php?topic=1035.0
However, our question is: do you currently support the selection between multiple alternative subtitles in your IPTV Player product (or rather in your DirectShow Filters which we will be using directly)?
If not, can you suggest any work-around for us to resolve this issue.
