Subject: [Vorbis] Reg: Bitrates support 576kbps in ogg vorbis
Message-ID: <20091210122426.44F8C1F1E30@zimbra.jasmin-infotech.com>

Hi,

 

I was checking for bit rates support above 500kbps in the libvorbis code, so
I tried to encode ogg files with bitrate 576kbps but the encoder OggdropXpd
gives maximum bit rate of only 500kbps. Does the Vorbis audio support bit
rate 576 kbps?

 

Thanks, 

Emima

Vorbis itself has no real concept of bitrate, and so it has no limits.
 Our specific encoders are not tuned for and do not offer bitrates
over 500kbps (for stereo CD-rate in any case), because that's the
point where it's becoming silly to use a lossy codec; you'd probably
be better off going with FLAC or a lossless codec.

.oga is any non-vorbis audio stram encapsulated in Ogg (eg, Speex, or CELT).

.ogx is just a catch-all for something that doesn't strictly fit in
.ogg, .oga or .ogv.  The extensions actually don't really mean
anything except as a helper suggestion to tie a media type to a
specific player application.  The underlying files don't actually
differ in structure (except for the old .ogg, which implies Vorbis
only).

Well, CD audio stereo has rate of 1411200 bits/sec, FLAC and similar will
typically cut it  by half, i.e. at best it'll be 700 Kbits/sec, so there is
some room for Vorbis yet :).

  Sergei.

I can only say that there is CD audio where bitrates up to 320kB/s (BVR peaks) 
make sense. The problem with FLAC is that even fewer devices support it than for 
Vorbis.

of course I meant "VBR peaks". Sorry!

Subject: [Vorbis] php and mime type
Message-ID: <4B28DFEE.9040208@mac.com>

Hi list,

I'm hoping to find a way via php, preferably without using exec() or 
system(), to reliably identify an ogg vorbis file via php.

Using

$fi = new finfo(FILEINFO_MIME);
$mime_type = $fi->buffer(file_get_contents($upload));

results in 'application/ogg'

My site accepts vouchers for herpetology records, but only image and 
audio. I do not wish to support video vouchers, but if an Ogg Theora 
file is uploaded, it also produces the mime type 'application/ogg' when 
looked at with finfo class.

I need a way to distinguish ogg/vorbis from other types of ogg files, 
and it really needs to be w/o exec or system calls as they are currently 
disabled for security and I do not want to re-enable them.

Is there maybe a pcre extension or something designed to look at vorbis 
tags that could potentially be used to verify the file is ogg vorbis?

After upload I do transcode (from ogg to mp3 and mp3 to ogg so that 
html5 audio with flowplayer fallback works) by cron job that pulls new 
audio vouchers out of database, and I could (and currently do) check 
there, but all record submissions require at least one voucher and I 
would rather catch non ogg vorbis ogg files on submission before the web 
app creates the record in the first place.

Thanks for suggestions.

Doh! I meant pecl extension

I found something from 2003 - http://pecl.php.net/package/oggvorbis

However, it looks dead.

Hi,

I can't play any OGG streams with Windows Media Player 12 after installing the Directshow filter.
I also tried Guliverkli2 and Media Player Classic Home Cinema and they wouldn't work either. Only Winamp can play the streams.
Here is the output I get from Guliverkli2 and MPCHC with the Gabest splitter (with Haali they just hang at 'open file'):

Hello,
I can reproduce the problem.  I have a set of 16 .ogg files; out of  
20 batch conversions of all the files from ogg to wav, it fails 70%  
of the time.

With the -audio-buffer 0 option, out of 20 batch conversions, it  
fails 0% of the time.

Thanks!
