AutoGK encoding stage question

[fewtch]

I noticed AutoGK now creates an intermediate .wav file before encoding to MP3. Just out of curiosity, what happens if the .wav exceeds 2GB on file systems that don't support it?

That would require the movie to be about 4 hours long, wouldn't it?

Not probable for a DVD but a real possibility with TS recordings. Maybe the Oscars? :)

@ydobon

total OT: now everyone knows which TV show we're watching :) (Actually its ended here already)

[ydobon]

:D :D Yeah. Don't you hate cliffhangers? (I also follow it from the UK)

That's true, but it makes me a little nervous anyway... the limit is nowhere near impossible to reach with FAT16/FAT32.

IMO (as a programmer myself) some provision should be made for the possibility, rather than resulting in truncated or no audio if the decoding stage crashed. Perhaps AutoGK should calculate if it's possible to reach that limit and throw up a warning box at least.

FWIW I think the limit is 1.99GB with FAT16 and 3.99GB with FAT32.

P.S. I'd bet $50 that if nothing is done, somebody will complain about probs caused by this eventually... ;)

I doubt that anyone who uses AutoGK still uses FAT16. For FAT32 its pretty hard to find a source that long. Its gotta be a capture and input file itself would probably always be larger then WAV produced from it.

Not necessarily. For example a Dreambox (http://www.dream-multimedia-tv.de/Bereiche/Produkte/DM7000.php) captures to files like
capture.ts
capture.ts.001
capture.ts.002
...
which I rename (for DGIndex-sake) to
capture_1.ts
capture_2.ts
capture_3.ts
...

I agree it's a difficult set of conditions, but I don't think a check/warning would be a bad idea. After all, once you know the video length, it's easy to estimate the WAV size, isn't it?

The video length is not known before job is started anyway.

[ydobon]

So? Start the job and once the length is known...
"WARNING: Intermediate WAV will be larger than 2 GB. If your disk is not formatted as NTFS, it's your fault" :D

Btw AutoGK will not run on FAT16 anyway as its needs long filenames...
