Implementing closed caption on Roku

Question

Hi All,My understanding is that with the Roku 2 support was added for closed captioning (this is based off the many posts concerning closed captioning with NetFlix channel).  I am developing a channel and the client has requested closed captioning be supported but i can not find any details on how to add closed captioning data to the stream.  Can anyone point me in the right direction?  Is there an XML file like the standards around some flash players or do you encode the data directly into the m3u8 stream?   Any advice is greatly appreciated!ThanksJeff

We are planning to support closed captioning via SMPTE TimeText in a coming software update. We don't support it today in the SDK.  We'll post more when it we have more to announce.

Does Roku still support SRT files?  You could try using those while waiting.

It's still in the development guide under Content Meta-Data

Under SubtitleUrl ("Since Firmware version 2.6:")
roVideoPlayer and roVideoScreen: Will display an overlay of subtitles stored in an SRT formatted file.
Example: "http://www.myco.com/vid/1932.srt"

Thanks for the responses. Is it possible to use an SRT file with streaming content? It seems that the instructions require you use <filename>.mp4 and <filename>.srt to make this work but in my case i am using m3u8 streams.

Thanks
Jeff
