Convert crashes on subtitle extraction and no more Conversions execute

[ateece 2]

So i've queued up a few folders for conversion and I notice that it keeps hanging; the conversions just stop; ffmpeg is no longer running in Task Manager.

Looking in the Emby log this seems to happen after an exception extracting the subtitles which leads me to believe there are 2 issues:

1. Exception during conversion of 1 file stops Emby from converting other files in the queue. It just shows a status of "Transferring". Opening the conversion job and pressing save allows it to continue to the next file.
2. ffmpeg subtitle extraction has issues.
3. Exceptions sometimes occur during conversion such as "File name cannot be null" when it is trying to copy the file (exception can be found in attached log file).

Logs attached but the exception is:

Hi, this should be improved for the next release of the server, thanks.
