CFLAGS / LDFLAGS
I notice that the user is not able to set their own CFLAGS or LDFLAGS in the ao, ogg, vorbis, and voribs-tools projects. Is there a reason for this? I understand the fact that these modules want to set extremely high optimization flags, and that most users won't know what these are offhand, but there are times when it is useful for the user to specify their own CFLAGS/LDFLAGS. For example,

Compile Problems
Hello, I've been trying to compile some things but have run into some problems. I've have the vorbis directory inside of /usr/src. I have compiled vorbis itself with no problems. I've also copied the results to their respective directories as per the README file. I've also compiled the XMMS plugin with no problem. However when it is installed in the

Can't compile CVS with non-gcc compilers
Without "no-dependencies" in every single Makefile.am's AUTOMAKE_OPTIONS line, automake will put gnu-specific instructions that will barf a) if you don't use gmake, and b) don't use gcc. This is actually in the automake manual, section 7.11, page 26 -- it's not an unexpected thing: "Currently, this support [automatic dependency generation] requires

MP3pro
So it looks like the Frauenhoffer boys are issuing an updated format -- MP3pro. They claim that it will give 128kbps/MP3 quality in 64kbps. I'm interested to see what others think of this. I'm also curious: I've seen others on the list say that Ogg/Vorbis' sound quality is "better" than MP3. Can this be quantified (or is this already on a web page somewhere)? I kinda

Thread issues: clarification
Monty -- I'm still running into problems with my threaded encoded, and I think I just figured out why. I have N threads running in parallel calling vorbis_analysis_blockout() and vorbis_analysis() to do the number crunching on the input samples. They all share a single vorbis_dsp_state -- my understanding was that this was ok; they only *read* from the vorbis_dsp_state, therefore not

By design or a bug?
Happy new millenium! Summary: I'm having a problem queueing up the ogg_packet results of vorbis_analyze() for later writing to an .ogg stream. The docs don't seem to say if this is permissable or not. Hence, I don't know if I'm using the API incorrectly, or if this is an actual bug. ----- Attached is a short patch to vorbis-tools/oggenc/encode.c (from CVS head, 01/01/01... I

Question re: vorbis_block_clear()
I'm running into memory leak and read-from/write-to unallocated errors in the cleanup phase of parallel oggenc. I see in vorbis_block_clear() that it references some fields on the vorbis_dsp_state that it cached during vorbis_block_init(), and conditionally does some cleanup based on the values of those fields. Does this fact effectively mean that you can't have multiple vorbis_block

voribs_analysis() question
A variation on questions that I've asked before... In working on the parallel version of oggenc (both threaded and MPI), a profiling run shows that the function vorbis_analysis() takes up the majority of the run time. This seems to be an obvious choice for parallelization -- send each vorbis_block to a different processor, and let them call vorbis_analsis() in parallel with each other.

vorbis_analysis() dependencies?
Per Monty's suggestions from a while ago, I have [finally] gotten around to playing with different schemes for parallel oggenc. Monty's main suggestion was to have a single thread loop over reading samples and calling vorbis_analysis_blockout(), and then queueing up the resulting blocks to be processed through vorbis_analysis() in other threads (in parallel). To verify that this works, I

vorbis' configure
It seems that the configure script in CVS does not check the CFLAGS environment variable at all. Indeed, on line 121 of configure.in, CFLAGS is explicitly set to be blank. Is this done for a reason? I see that several sets of CFLAGS are passed into the Makefiles by configure based upon specific architecture/compiler combinations -- perhaps this is the reason...? I ask because users may wish to

Non-gcc build problems
I sent a message about 2 weeks ago about build problems at the head of the CVS tree with non-gcc compilers on POSIX systems, although I didn't correctly identify the link problems as being static-library only (see my previous mail about "static link broken"). Some problems have been fixed, but some still seem to be there. I have edited my original mail to list the problems that

Makefile.am patch
Since vorbiscomment is being resurrected in a new form, can someone please fix the vorbis-tools/vorbiscomment/Makefile.am? There's two things wrong: 1. Using _LDFLAGS doesn't allow the user to specify their own LDFLAGS. _LDADD or _LIBS should be used instead. 2. The order of libraries is wrong such that it won't link properly when compiled statically. Here's a trivial

Bug #4
Hi. I created a patch for Bug #4 (ogg123 not honoring /etc/ogg123rc) and uploaded it to Bugzilla, but I have the feeling that the Bugzilla is somewhat neglected... so I just send the patch here. The changes are very simple, one typo (I guess) was fixed (from "/etc/ogg123.rc" to "/etc/og123rc" as it's documented), and I changed an if to a while-loop to make it read the

ov_time_seek to 0s fails... AGAIN
Hello everybody, I sent something about this before, but this bug is still there, so... If you call ov_time_seek(vf, 0); it will fail, returning OV_EFAULT (from ov_pcm_seek_page). I think this must be a bug, because seeking to 0 seconds *should* be OK. Another thing, when ov_time_seek fails with OV_EFAULT, you cannot continue playing (because of the goto seek_error). This is not clear from

Application Crashes When Calling ov_time_seek() function
I’m running into a problem with my application crashing when I make a call to the ov_time_seek() function. The call includes the OggVorbis_File and it is indeed seekable, as I first check that using the ov_seekable() function. Everytime, however I try to seek forward, the application dies with a core dump. I’m working with the example from the “VorbisFile Documentation” site. The application

seeking
Hi, I need to know if it is possible to seek the Speex stream. I want to have an ability to seek in time, just like Vorbis does. Vorbis has function "ov_time_seek" and I want something like this from Speex. Is this possible? Thanks for any reply.
