DVB subtitles

Anybody know of a tool which can extract/ and or OCR DVB-T subtitles from mts streams? Preferable to srt

Try projectx. It works for .ts files but I'm not sure about .mts. Subtitle Edit is good for OCRing them.

yeah projectx just gives me 30000+ errors (literally) Haven't tried Subtitle Edit yet.

I tried testing the output in subtitle edit and it looks rather flakey alas.

I wrote a simple tool that can extract DVB-T subtitles from MPEG-TS and OCR's them with a Tesseract engine 3. Results are not perfect, but recognition can be improved with training Tesseract for specific font. Unfortunately that is quite complicated process. You can find this tool

I believe you have hard subtitles :) some call them burnt-in, in other words the subtitles are part of the image, that also explains the other issues you have reported. There are tools that "extract" hard subtitles, but you have to test them yourself, on your particular file you have, see videohelp for a list of them.

Can you upload some samples somewhere ? Some transport streams are missing PAT and PMT tables or interval of these tables is way to big and whitout them it doesn't even start searching for subtitles. I think that some tools exists that can rebuild these tables.
