Okay, before I submit my patch to make libao produce sorta-streamable wav files, I want to know what these partial wav files do to various players. I've posted two sample wav files on my webserver: http://volsung.dhcp.asu.edu/~stan/infinite.wav http://volsung.dhcp.asu.edu/~stan/zero.wav The first uses a riff and data length of 0xFFFFFFFF (approximately infinite) and second uses a riff and data length of 0. So far play (the frontend to sox) stops immediately on zero.wav and plays infinite.wav with a warnin...

I've been kind of busy lately, but I wanted to see what's up with ao after the build change. I was able to check out the vorbis module, but when I tried to check out the ao module I saw this: [stan@volsung vorbis]$ cvs -d:pserver:anoncvs@cvs.xiph.org:/usr/local/cvsroot co -r branch_postbeta2 ao cvs server: Updating ao cvs server: Updating ao/doc cvs server: Updating ao/include cvs server: Updating ao/include/ao cvs server: Updating ao/src cvs server: Updating ao/src/.deps cvs server: Updating ao/src/...

Hi there. Sorry I may be a little off topics with this mail but I have already written to the official libao maintainer (volsung@xiph.org) and he is the one who suggest me to write here. As I did not see any more suitable mailing list @xiph.org here I am. My point is that I have recently written a win32 driver for the libao and I would be glad to see this contribution include to the official libao project. As the offici...

I've been trying to tackle the vorbis source. I ran across what I think is a missing dependency in the vorbis-tools directory. Since ogg123 and vorbize are staticly linked to libvorbis and vorbisfile, when those file change, the executables should be rebuilt. Below I've attached a patch. (I hope it works. I am sort of new to patch and diff.) BTW, I've been trying to find a good

Since 1.0rc2 was released i have found that ogg@64k sounds almost like mp3@128k (in 95% of the 3000 files i encoded...) I tested 1.0rc3 and 64k bitrate (quality=0.0) gives less good quality than before. And bad : it takes longer to encode ! (1.7x vs. 2.0x on a P2/500MHz) Effectively 64k ogg files encoded with rc3 are smaller than files encoded with rc2. I hear people debatting on how satisfied

I'm reordering the code in ao_wav.c that writes wav files to prevent the problem we had earlier. If ogg123 was improperly terminated (Segfault, kill -9, etc.), the output wav file was not even recognizable because the header was totally blank. I have found that at the start of playback (from libao's perspective), I know all of the wav header info except two things: 1) The length of the

I am about to commit HTTP streaming code for ogg123. This has no relation to the discussion about "real" steaming Ogg; it just downloads and plays at the same time. But unless you have a direct T3 connection, it'll almost definately break up quite frequently. Solution? Buffer. But I have other things to work on for the rest of the day... Any screaming objections? This has been

For those of you who want to be able to decode Ogg Vorbis files into other formats, SoX (the swiss army knife of audio programs) now has Ogg Vorbis support in CVS. It can read Ogg Vorbis files and export the audio in any format SoX supports. You can also write Ogg Vorbis with it, but, because of limitations in the design of SoX, only output at 128kbps is supported. Note: Instructions on how to

[I'm still poking around in vorbis-tools. Here's another trivial patch.] In ogg123.c, the function get_stream goes down a linked list looking for the nth stream. Currently it will run off the end of the list and dereference the NULL pointer if the list is smaller than n. Attached is a patch to check for a null list and abort. Would assert() be a better way to do this? -=-=- Stan

Okay, here's the patch that should fix byte-ordering madness. The basic rule with libao is that samples have to be in native byte order. All of the drivers will assume this, and libao provides a ao_is_big_endian() function for library clients (and sometimes drivers) to test their byte ordering. I would appreciate it if someone on a big endian platform test ogg123 and make sure that it works

Just so people know what I'm working on (between physics assignments), here's a quick list of what's currently in the pipeline: * I received an IRIX patch which I am very excited about. I'll be submitting that shortly. * A month ago another user sent me a very small patch that improved ALSA performance on his machine. I don't understand what it does exactly, and would

Ack! I hate it when I have to fix my own crappy code. :) I present the endian fix for the wav output driver. Apply it along with the endian-fix.patch I sent earlier and things should be okay. Hopefully. Kenneth can check me on this with his PowerPC. --- Stan Seibert --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/ To unsubscribe
