similar to: ogg vorbis decoding

Hi devs, I am developing winLAME, a frontend for LAME, and it also supports Ogg Vorbis decoding and encoding. I've got a question about the new API function vorbis_encode_init_vbr(). Do I have to call vorbis_encode_init() before to set the bitrate(s)? And what is a good default value for the "base_quality" parameter? I read on the mailing list that ABR use in Ogg Vorbis is not so

Hi vorbis-devs, I use the Ogg Vorbis libraries built from the win32sdk in winlame. Since the rc2 DLL's are not functioning, I compiled them by myself. The apparent reason is that some data arrays like _residue_P were not shared among DLLs. I looked at the code, and found that IMHO dirty hack in vorbis/win32/src/shmmap*.h that maps the data arrays. Why not placing the data arrays in

Hello Hope you don't mind another newbie's question. Further to GIE's email about problems compiling decoder_example.c example (MS VC 7) using debug static ogg/vorbis libs, we'd appreciate any help getting the example files to compile on MS VC 6. The zip files we have downloaded are: libao-0.8.2.zip libogg-1.0rc3.zip libvorbis-1.0rc3.zip vorbis-sdk-1.0rc3.zip

decoder-example is a complex interaction of lots of Vorbis stuff. vorbisfile (OggVorbis_File) is much simpler. So why is the example code based on the complex stuff? I ask because I am trying to simplify ogg123, and add some features. Kenneth --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/

I am wondering if buffer size for my decoding to pcm can be predicted dependably as follows. So far, the one problem I have had is when I have played a file of only about 5k. The buffer was a little less than 10% too small. I "solved" that by padding the result with an extra 20 percent. However, I have been told that I should be able to rely on the value of ov_pcm_total. char*

Hi, I put together a small a Visual C++ 6.0 project that uses the code from vorbisfile_example.c. I open an ogg file in binary mode and when ov_open gets called, it always fails. I then put together another project and compiled vorbisfile so I could see where the error was occuring. It is happening in _fetch_headers when it calls ogg_stream_packetout. The return values is -1, which means there

Hi, I have looked through the documentation available from the downloads and the web and haven't yet come across a block diagram which shows exactly how the process of going from a .wav file to a .ogg file works. I suspect it is the same as the mp3 process (with a different psychoacoustic model). I found this document:

Why ov_open_callbacks(fd_, &vf, NULL, 0, OV_CALLBACKS_NOCLOSE) takes so long to open OGG file? The OGG file has just 210 MB. It takes a lot of time open the file. I am working on OGG audio recorder and player. Thanks in advance! With kind regards, Pavel

I have a couple of questions with respect to "vorbisfile_example.c" in the ov sdk. 1) Near the end, there is a comment that says "we don't bother dealing with sample rate changes, etc, but you'll have to." I assume the author is regarding to different sample rates as a whole, not dynamic sample rates. Am I correct in that assumption? 2) That etc

There isn't a lot of guidance on how exactly to run the codec I compiled out of cvs just now, but I expected the following to work: cat test.wav | encoder_example | decoder_example But the decoder fails with: End of file before finding all Vorbis headers! Is this a bug? Or am I missing something fundamental? Should I attach the test.wav? -- Daniel --- >8 ---- List

I've fixed a heck of a lot of stuff in the time frame of just over ten minutes. And you all care... right. I actually ran Vorbize, and discovered some stupid bugs (e.g., segfault???). Fixed. Both Vorbize and Ogg123 should now speak fluently in Monty's comment-eese. I'll be working on getting both to implement all the comment tags; I'm seriously considering dropping all comment

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I'm writing a simple application to decompress a set of Ogg files to raw PCM format, using vorbisfile, because that is the simplest way of doing it. These Ogg files are sounds for a game, and thus sometimes very short (about .25 s). However, vorbisfile has severe problems with Ogg files that are smaller than the CHUNKSIZE which is #defined

Hi list, I'm looking into getting OggVorbis support put together for the Curl language (a Linux version is coming out before the end of the year www.curl.com), and am wondering if I could get some *newbie* help... Which of the APIs in vorbisfile are absolutely needed to decode a Vorbis file? I want to keep things simple to start off with and see if I can get Vorbis and Curl working on the

Hi! I'm trying to write a vorbis plugin for my MP3/Music/Media player (http://elmp-tng.sourceforge.net). I'm using vorbisfile, and ov_open_callbacks() (to interface with my VFS layer). The problem is the same using plain ov_open() though... Some files play perfectly, while others (most) fail. ov_open returns OV_EBADHEADER. The really strange thing is that both ogg123, and the simple test

Hi! I'd like to make a stereo 8-bit wav file from a stereo (16 bit) ogg vorbis file (in delphi, with the vorbisfile). I use: ret := ov_open_callbacks(filein,vf,nil,0,ops_callbacks); if ret = 0 Then begin fileOut := TFileStream.Create(savedlg.FileName,fmCreate); repeat ret := ov_read(VF, pcmout, BufferSize, 0, 1, 1, nil); //'cause of the 8-bit

Hi` Is there some example code on how to use ov_open_callbacks with VorbisFile? The documentation I found is _very_ sparse and if possible I don't want to spend much time adding streaming from memory to my code. http://www.xiph.org/ogg/vorbis/doc/vorbisfile/ov_callbacks.html <p>Thanks, -- Daniel, Epic Games Inc. <p>--- >8 ---- List archives: http://www.xiph.org/archives/

I have been having problems compling vorbis on my computer( running redhat 7.1 ), it gives me a bunch of errors about vorbisfile.o( at least that what the errors are complaining about...I don't know enough to figure out what is wrong ). Below is the output I get from compile: Making all in examples make[1]: Entering directory `/home/mchavez/devel/vorbis/examples' /bin/sh ../libtool
