I. Noted. Will add that profile to existing set. II. I'll look into allowing [srtFile] and some of the other filenames inside encoding profiles. NOTE: streambaby does support closed captions from SRT files - if you have file.srt file accompanying your file.whatever video file it will automatically add captions while streaming. There are options for controlling font size as well. (I worked on the initial implementation of closed captioning support in streambaby and it turned out it actually works fairly well). III. I can add an option for additional arguments to t2extract. Please file an issue request citing this thread which is useful for tracking the issues and for me to get you development versions of kmttg to try out the enhancements.
