Would you be able to confirm/deny that MMPPF (Win8) supports the SMPTE Image tag in TTML Captions.

For example (taken from: https://www.smpte.org/sites/default/files/st2052-1-2010.pdf):

I have tried using the image tag but no image is shown and no error is produced.

Hello, MMPPF for Win8 does not support SMPTE-TT images at the moment although we are hoping to add this in a future release.

Hello,

I currently work on DVB-SUB (en 300 743) to SMPTE-TT transcoding.
If the current MMPPF has currently no support for SMPTE-TT images, is someone aware of an alternative player, even something young and not stable, I would like to do some first tests with my output streams.

Thankx,

Hello, Any precision for this release date ?

And how difficult is it to implement in the MMPPF ?
I have neither .NET nor MMPPF background, 'only' C/C++ on linux (and win32 10-15 years ago ...), but if the MMPPF framework is well built, I suppose it should be similar to display some text (like TTML for EIA-608/DVB-TXT does) or a PNG image ...

Any pointer fo familiarize with MMPPF / image display ... related to this subject appreciated.

Thanks in advance,
