[08:26] <shifter1> Do any know how ffmpeg reads from character files?  Is this question better suited for #ffmpeg ?
[08:59] <shifter1> ping
[09:07] <burek> ffmpeg is missing docs info on "analyzeduration"
[09:07] <burek> i dont want to file a bug report just because of that :)
[09:10] <cbsrobot> burek: ffmpeg -h | grep analyzeduration
[09:10] <cbsrobot> shows
[09:10] <cbsrobot> -analyzeduration   <int>   .D... how many microseconds are analyzed to estimate duration
[09:11] <shifter1> it doesn't seem to be in the man page
[09:11] <cbsrobot> ah ok
[09:11] <shifter1> I could be worng
[09:12] <shifter1> it should also probably be in the ffprobe man page too
[09:13] <burek> yes, its not in the html doc :)
[09:13] <burek> crap, works only in 1 chan :)
[09:13] <burek> http://ffmpeg.org/ffmpeg.html
[09:13] <burek> :)
[09:15] <ubitux> a lot of options are undocumented
[09:15] <burek> really?
[09:16] <ubitux> you might want to file a bug report for this
[09:16] <burek> too bad :/ people usually use google to find help..
[09:16] <burek> maybe it would be a good idea to periodically do ffmpeg --fullhelp and make html file out of it and publish it?
[09:16] <ubitux> check libavformat/options.c
[09:16] <ubitux> then git grep each option
[09:16] <ubitux> most of them don't appear in the documentation
[09:17] <burek> i see
[09:17] <ubitux> burek: --fullhelp is x264 specific
[09:18] <ubitux> i'm not sure having a ffmpeg -h page is a really good idea though
[09:18] <burek> why not
[09:19] <burek> just setup a cron that does ffmpeg -h > /var/www/bla.html :)
[09:19] <ubitux> because some options will be documented two times
[09:19] <ubitux> otoh, pointing out ffmpeg -h in the main documentation page, saying it might gives a more complete list, might be better
[09:20] <burek> im talking this because of google and its indexing power
[09:20] <burek> so that people can search for a problem and get results fast
[09:20] <burek> it doesn't have to be on the same page as the official documentation
[09:20] <ubitux> where would you integrate a link to this?
[09:20] <burek> it could be (and should) completeley separate page
[09:21] <burek> wherever suitable :)
[09:21] <burek> google bot will find it
[09:22] <ubitux> if you're going to do it, i'd suggest you add anchors to the list
[09:22] <burek> well i could, but i don't have enough privileges to access the machine and create a cron job :)
[09:22] <shifter1> the man page is pretty full
[09:23] <shifter1> why not dump the man page to html 
[09:23] <burek> well, it's a good idea
[09:23] <burek> the only problem i see here
[09:23] <ubitux> the manpage is the same as the online documentation
[09:23] <ubitux> (the source is the same)
[09:23] <shifter1> is it?  how often is updated?
[09:23] <burek> is that people have to update 1) html docs 2) ffmpeg -h options and 3) man ffmpeg
[09:23] <ubitux> so if the online documentation is lacking documentation, the manpage too
[09:24] <burek> i see
[09:24] <ubitux> burek: so piping ffmpeg -h, and generates a page with each line like this: <a href="#opt_analyzeduration">-analyzeduration</a> [...] might be a solution
[09:24] <ubitux> this will help user-helpers to point out an option
[09:24] <ubitux> this could be scripted quite easily
[09:24] <burek> yes, that would be great
[09:25] <ubitux> also note afaik the -h option depends on how you build ffmpeg
[09:25] <ubitux> (for codecs/formats specific options)
[09:25] <shifter1> --help is what I use
[09:25] <burek> yes, that's why i wanted to build a big fat static ffmpeg, with everything in it, but when we discussed the legal issues, I just gave up on it
[09:25] <ubitux> :)
[09:26] <ubitux> OTOH, you could also just add the documentation to the most common missing option docs
[09:26] <ubitux> sending a patch for this isn't much trouble
[09:26] <burek> the problem is to learn git :)
[09:27] <burek> i mean, not for me now
[09:27] <burek> because i alredy did it
[09:27] <ubitux> simple usage is pretty straightforward
[09:27] <burek> but for new people, which just use ffmpeg and notice something to report
[09:27] <burek> do we have forum ready ?
[09:27] <burek> or still not :
[09:27] <burek> :(
[09:28] <ubitux> no idea, still a WIP i guess
[09:28] <burek> man.. we could build 5 forums so far.. :s
[09:28] <burek> why does it go so slow
[09:28] <ubitux> people who care seems not much available
[09:32] <burek> well i have spare time
[09:35] <ubitux> then contact zeranoe
[09:35] <ubitux> :p
[09:37] <burek> i will again :)
