Certain files don't read properly

[ghost]

Hi Buzz, thanks for putting this together! Everything works great for short clips (15 seconds, 3-5MB) but I've tried a couple longer ones (2 min, ~11MB) and they do not grab the data. I tried on your demo page as well and it's having the same issue. Any idea what might be causing this?

As a note, the desktop app for MediaInfo pulls the data correctly for both files.

The screenshot below shows the longer clip on top and shorter one below it.

Solution was to increase chunk size. Misread the size originally.

I successfully read files several GiB in size.

But I also witnessed the behaviour you are describing. I didn't invest time investigating the issue further as this is a proof-of-concept project.

Re-opening as I don't see this entirely solved.

The result should be the same independent of the chunk size.

If somebody would like to investigate please go ahead!

Hey @buzz
I'm also not convinced that #6 which you just closed is the same thing. Those 2 files I put on Dropbox are only around 40MB, but I have other .mp4 and .mpg files that are well over 900MB which are handled just fine.
Also I don't see mediainfo.js hanging or throwing an exception on these files, it just doesn't extract any details.
Thanks

Hi @SaintFlipper
I have to admit I can't prove that this is actually the same bug. As you pointed out it seems this is not about file size. I changed the misleading title of this issue to reflect this.

But then all cases I found so far that show the same poor output, and work without problem with command-line mediainfo, are solved by increasing the chunk size.

This is why I'm fairly certain that this is the same thing.

I propose we track further investigation in this issue until we have proof your theory is right and this are actually two unrelated bugs.

Thanks @buzz
Fingers crossed that they are both caused by the same underlying issue, rather than trying to track down two separate things. Let me know if you'd like any more pass/fail test videos as I have many of various sizes.
Thanks for all the good work on this by the way. Much appreciated and very useful.

Should be fixed in v0.0.3. Otherwise please re-open.
