View Full Version : Calculating size of M2V?

LIGHTNING UK!, in IFO mode you presently show the time, fps and size of the selected PGC. I'm looking for an easy and quick way to know the actual size of the m2v stream in bytes to allow some derived ABR calculations I'm tinkering around with (without demuxing).

I just curious if you have enough information available to you in IFO mode to calculate the final size of the m2v? Do you know the bitrate of the ac3s? Even if you do, I guess subs might be a problem?

/Add: Hopefully not to distract you from the above, I noticed Stream processing follows the file splitting settings. The second increment of a m2v seems to have an invalid header.

Maybe consider a setting to allow file splitting to be handled separately for streams? Switching file splitting back and forth is not a problem at all, but remembering to do so can be :)

No, I probably dont have enough info. That said, I've never really looked into it to be honest.

As for invalid headers, I make no attempt to correct these for m2v. You get what's read and that's it.

Like you said, ripped streams are usually made into 1 big file - and then the problem doesnt exist.

I dont quite get why you stream process sometimes and then dont others? Surely if you have a way of doing things you'll always do it that way? So basically just leave the file splitting for IFO mode on 'Auto'!

Sorry but it would be a bit of a pain in the arse to change (or add to) those options now so they'll be staying as they are.

Great job on the new release. I was amazed at the download counts of previous versions. I think I saw one with 6 million? Wow.

As for the other, np, just got to remember to shift splitting back and forth when needed for m2v stream.
