title: Is it possible to determine if a subtitle track is imaged based or text based with ffprobe
body: <p>I'm writing a script that burns subtitles into video files to prepare them for a personal stream I'm hosting. I'm having a hard time finding which type of subtitle is used in the file. I use ffprobe to get the files' information, and I can get stuff like the codec type, but I was wondering if there is a way to determine if a subtitle track is image based or text based. I can only think of getting a list of all possible codecs and match the codec type with this list but it would be very useful to have an info somewhere that can tell me &quot;OK this is an image-based subtitle track&quot;, as when I burn I cannot use the same filters with ffmpeg to burn image vs. text subtitles.</p>
