similar to: Status of thread-safeness of libvorbis?

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

Hello, We are running samba on SGI/SUN/HP file-servers. We have about 600 concurrent clients. We are using samba version 1.9.17p4 en have a problem with self extracting exe-files on a samba-mounted disk from NT 4.0. ( This problem also exists with earlier versions of samba e.g. 1.9.16p11 ) If you place the exe-file in a directory called "12345678.123" ( 8.3 filename ), there is no

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

Hello, We have a problem with samba 2.0.3 and a lotus notes 4.6.2 client. The local lotus-notes user's databases are on the home-directory of the user in directory notes/data. The home-directory is a directory on a unix (HP) file-server and is accessed with samba. If a user wants to open the databases in his notes/data directory, he get a notes error "The parameter is incorrect".

I read some lines in libvorbis/include/vorbis/codec.h: /* vorbis_block is a single block of data to be processed as part of the analysis/synthesis stream; it belongs to a specific logical bitstream, but is independant from other vorbis_blocks belonging to that logical bitstream. *************************************************/ My question. Does this imply that vorbis_analysis

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

Hello everybody, Since there is almost no documentation on the vorbis algorithm I have to post some questions on this list. To remind you: I am trying to implement a parallel (multithreaded) ogg encoder, using a manager-worker model. 1. About the vorbis algorithm. I plan to let the workers each process a buffer of vorbis_blocks. The point is that each worker has to start somewhere and can not

Hello, I have some code that encodes PCM data into a vorbis stream, using the workflow shown in http://www.xiph.org/vorbis/doc/libvorbis/overview.html. By analyzing that process with valgrind/cachegrind I found out that 95% of the time used for encoding is spent in the function "vorbis_analysis(&vb, 0)". My question now is: would it be technically possible to parallelize this? I

Hey I am playing with a LOT of threads right now, and I want to know if the threads all need their own little vorbis encoders running in them or what exactly is threadsafe in vorbis? So here are the functions that would be called from many threads of with buffer = vorbis_analysis_buffer( &m_vorbisDsp, 4*DATA_CHUNK_SIZE ); vorbis_analysis_wrote( &m_vorbisDsp, dataLength/dataSize );

Hello We are running samba on SGI/SUN/HP fileservers. We saw a problem on the SGI fileservers. After a while a lot of defunct smbd deamons were hanging and occupying the slots in the process table. We saw the problem with IRIX 5.2 and samba 1.9.16p11 and IRIX 6.2 and samba 1.9.17.p4 . Has anybody seen this problem before? This is a serious problem, because the smbd daemons are filling the

Hi, Lately, my oggenc builds (from CVS) haven't been running correctly. In a few debugging sessions, I've found that I'm getting a divide by zero exception. The exception happens in accumulate_fit (floor1.c), line 455: int weight=nb*info->twofitweight/na; Here is the call stack: accumulate_fit floot1_fit mapping0_forward vorbis_analysis oe_encode main The

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.

Hay! Has anyone come across these errors using valgrind for the oggenc tool or the encoder_example.c: ==13108== Invalid read of size 4 ==13108== at 0x4155734: _vp_offset_and_mix (in /usr/local/lib/libvorbis.so.0.4.1) ==13108==

Hi, I have recently implemented encoding/decoding to/from OggVorbis in my app, with the code being based upon the Libvorbisenc sample code supplied with the SDK. It all works very well indeed (encoding from a PCM file, then playback), except that no matter the length of the source PCM file, the last (approx) 4 seconds of audio is always missing from the Ogg file. I am trying to find some

I'm in the process of collecting performance data on my platform and I thought I'd test the difference between double and float performance. So, I replaced all occurances of double in vorbis with float (as was suggested should work). I ended up hanging at: #0 0x0002695c in cacm283 () #1 0x00026dd0 in vorbis_lpc_to_lsp () #2 0x0001b3cc in forward () #3 0x0001cac8 in forward () #4

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 <p>Hello, I have encountered a situation where oggenc core dumps. I am using vorbis-tools 1.0 on Solaris 8 x86.

Hi there. I'm getting this exception, Floating point division by zero, when encoding at, for example, 22050 hz. This doesn't happens in a specific song or audio, it mostly happens after several calls to vorbis_analysis. This also doensn't happens, at least so far, at 11025, 8820 or 44100. Also, it doesn't seem to happen at low qualities (0, -0.1). The exception is generated in

Hi All, I m having a strange problem with the Ogg-Vorbis writting code. The code I m using to write is skipping some samples at the end of the file. For example I m converting the 10000 sample .wav file ( 441000 sample rate , 16 bit depth , stereo ) to ogg format. But while reading the ogg file I only find 5824 samples in the ogg file. Can any one suggest what could be wrong in the code. Is

I've been trying to piece my way through the encoder_example.c program to better understand how to encode files as ogg/vorbis. I'm stuck on two sections of the code. This is the first /* uninterleave samples */ for(i=0;i<bytes/4;i++){ buffer[0][i]=((readbuffer[i*4+1]<<8)| (0x00ff&(int)readbuffer[i*4]))/32768.f;
