Hi Mark,

if you think that my post is in a wrong section, please, move this thread to the correct place.

I need to know the size for debugging utilities.
Running a smooth streaming session, i wont' know, what's the size (byte) of a downloaded chunk.

I find this project on github
https://sdkdocs.roku.com/dosearchsite.action?where=sdkdoc&spaceSearch=true&queryString=IsDownloadSegmentInfo

How can i get chunk size info ?

if you have any suggestions please let me know

Thanks

roVideoScreenEvent and roVideoPlayerEvent contain these undocumented event types: 31 - IsDownloadSegmentInfo(), and 37 - IsSegmentDownloadStarted(). I'm not sure why they're undocumented. I've found them useful for debugging HLS streams. You can figure out the event fields from the GitHub file you linked to.

IsDownloadSegmentInfo() does contain the size of each downloaded HLS segment. I'm not sure whether it would apply to smooth streams as well. You could try it and see.

Hi belltown,
i have tryed to play an ism, stream format, using your Git code.
That's the Manifest link:
http://playready.directtaps.net/smooths ... m/Manifest
Updating the search link on documentation ( https://sdkdocs.roku.com/display/sdkdoc/roVideoScreen#roVideoScreen-SupportedInterfaces i have found info about ism support, so i modified categories.xml file in your code, to play that contents. 

Starting the video i read this for example:

...
uiPlayVideo. roVideoScreenEvent [31]-isDownloadSegmentInfo. Message: Download segment info. Index: 58. Data: 0
     Sequence:         58

You said: "I'm not sure whether it would apply to smooth streams as well".  Why do you think so?
