Overwriting PES and mux/demux errors.

I will confirm these issue, thanks

@andersc can you outline the neccessary fixes? we also used a fork and are restrcutruring a bit. also your code seems to have moved into a repo which has no shared history with this one, so its hard to merge

[maddanio]

I just checked, the only use of string is in PMTElementInfo, should that be replaces by vector or such?

[andersc]

@maddanio I made so many changes to the original repo it's not possible for me to be that specific. Just fork my clone to get to where I'm at ->

https://github.com/Unit-X/mpegts

Then just pullrequest from there.

Ok, i tried porting your unit tests, but I think its too hard, so i switched to your fork. One thing: in both versions the demuxer is sensitive to the block size it is fed. Basically the simple buffer borders must somehow align with the demuxer granularity, otherwise things just fail oddly. I would advice a streaming input here, i.e. either an std istream or a callback. Easiest would likely be the latter, and then plug that into simple buffer.

[andersc]

OK. Great you found a bug. Would it be possible for you to write a failing unit test? Then I'll fix it. Or provide more detailed information.

[maddanio]

Hmm, thats tricky, I think you kinda assert that packet size is divisible by 188 in your tests, which seems to be a magic number. its kinda obvious though that it is fragile like that, as the demuxer very rarely checks for emptiness of the buffer, i.e. it being used up, but happily reads from it the rest of the time. in debug mode that will probably trigger the assertions in the simple buffer

let me try...
