eac3to - audio conversion tool

[Bigmango]

Hi,

SUP (PGS - bluray) subtitle extraction from mkv has been broken for many years.

-> loading the sup in bdsup2sub or any subtitle edit for ocr, etc... always tells me the subtitles are corrupt. Extracting with gmkvextract works perfectly. (this bug has been going on for many years, tested/used on many different systems).

Could you please fix this? (AND if you please, while you are at this please also make sure/confirm that any FORCED tag flags are added in the extracted track name. I dont remeber if eac3to does this, but gmkvextract doesn't and it's a lot of work always veryfying with mediainfo if there are forced tracks in the source).

(As it is now: I always have to demux the mkvs 2 times : first with eac3to to fix the audio delays, then with gmkvextract to extract the subtitles).

Many thanks!

Not always, only when SUP (PGS ) are muxed compressed (zlib) in mkv (like is the default). Normally you obtain zlib compressed SUP not supported in other soft.
From BD files (m2ts) work fine because aren't compressed.

BTW eac3to is an abandoned soft and can't be improved for this or other feature request.
With UsEac3toGUI you can extract the SUP decompressed because work like a GUI for MkvExtract like gmkvextract.
