Bug 49489 – Mplayer-1.0-pre4 has problems with locale

• Product: Gentoo Linux
• Status: RESOLVED UPSTREAM

[Description Sebastian 2004-04-30 05:37:07 UTC]

Hi,

I use mplayer to play divx movies on my dvb card. It basically decodes the divx/xvid/whatever and encodes it to mpeg2 on the fly and sends it to the dvb card. I use it for VDR (a linux video disk recorder software). Anyway, there are problems usig pre4 wth 23.976fps movies that weren't in pre3. 

Here's the output of pre3:

I was on #mplayerdev at freenode and this is the convo with the devs there:

<dalias> maybe there's some way to enable it sikkh, i dunno
<micmac> Hi. I got a problem and no answer in mplayer. Can I post it here?
<dalias> better to wait on #mplayer or post to mplayer-users list, but...
<dalias> we're being really idle and stupid in here right now
<micmac> Ok :)
<dalias> so we might as well
<dalias> answer a question
<micmac> I got a problem with pre4 when I want it to send the video to my dvb card. pre3 works, pre4 doesn't. It tried FFMPEGs lavc to decode the vid but fails with "[mpeg1video @ 0x849cf60]removing common factors from framerate" and "[mpeg1video @ 0x849cf60]MPEG1/2 doesnt support 29/1 fps". If you want to you can see the whole error message and the output of both mplayer versions at [URL]http://www.vdrportal.de/board/thread.php?threadid=16398&sid=[/URL]
<dalias> uhg ok
<dalias> just a sec
<dalias> the problem is locale
<dalias> in your locale "," is the decimal separator
<dalias> so 29.97 gets parsed as 29
<micmac> I don't understand. Why does it work with pre3?
<Mosu> probably because pre3 hasn't used setlocale or sth like that
<dalias> because the old libavcodec ignored the fact that the framerate was invalid
<Mosu> or that
<dalias> mosu, no, old lavc silently let you use bad framerate and results were probably unpredictable
<micmac> So it's a Gentoo problem in my case?
<dalias> micmac, no
<dalias> if mplayer is going to support locale, it needs to work around problems like this
<sikkh> dalias: btw Jeff Dike (UML creator) also uses emacs ;)
<micmac> Then it's a problem with my "export LANG=de_DE@euro"?
<dalias> the problem is that people put locale support in mplayer without thinking about it
<dalias> so it's buggy
<dalias> yeah
<dalias> if you get rid of that it will work fine
<dalias> you could also try using 30
<micmac> How can I get rid of it with ./configure?
<dalias> and see if that gets rounded to a reasonable number
<timebomb_> micmac: just put an alias that overrides that lang
<timebomb_> then when you use mplayer it will have no probs
<dalias> --disable-i18n
<dalias> or what timebomb_ said
<timebomb_> u could e.g. use alias mplayer 'LANG=en_US mplayer' in your .bashrc
<micmac> timebomb_, sorry, I'm nut dumb but maybe my English is not too well. Can you say that once more please.
<timebomb_> assuming that you use bash from that export and gentoo
<micmac> oh. ok thx.
<timebomb_> hehe nut dumb might be misunderstood :D
<micmac> Can I paste this convo in the [URL]www.vdrportal.de[/URL] thread I opened?
<dalias> sure
--- timebomb_ ist jetzt bekannt als timebomb
<micmac> ty guys. Are you gonna try to get rid of this locale mixpup in the future?
--- ChanServ gibt Voice-Status an timebomb
<timebomb> that might be so
<timebomb> maybe with pre5 :)
<micmac> Thanks!
<micmac> bye bye
<timebomb> bye

Maybe you guys can have a look at this behaviour, too.

Thanks
Sebastian

Please confirm this in pre5.

Hello!

Yep, same thing with pre5:

I ask Juri in the mplayer-dvb mailing list if this could be fixed easily. And he said that I would have to change the 29.976 to 30. Well, that works:

But isn't that the wrong fix? Isn't it only a workaround? Well, maybe it's just fine. At least it works. Maybe this is a good time to close this bug #? What do you think?

[Comment 3 Chris White (RETIRED) 2004-11-10 20:46:17 UTC]

Can you post a bug for this in the MPlayer -dev mailing list and in their bugzilla?  Please also provide the tracking number.  I have a few ideas on how to solve it, but I'm not 200% sure.  Thanks ahead of time.

[Comment 4 Sebastian 2004-11-11 03:10:46 UTC]

Hi Chris!

Are you sure you want to investigate further? I found that lavc no longer accepts float input. If you feed it with -vop lavc=5500:30 instead 29.97.. all's well. If I remember correctly I already posted this quite some time ago at mplayer-dvb. But response was rare. I was told to use int numbers instead. How about just closing this #?
