When I was trying to find yesterday's xmms-plugin bug, i have noticed that seeking in stream without seek-table isn't very good. With attached patch it is much better. -- Miroslav Lichvar -------------- next part -------------- --- src/libFLAC/seekable_stream_decoder.c.orig 2003-02-26 19:41:51.000000000 +0100 +++ src/libFLAC/seekable_stream_decoder.c 2003-07-09 23:49:35.000000000 +0200

I think I've gotten FLAC__lpc_restore_signal() about as good as I'm going to get it. Here's what I have: -a new file, lpc_asm.s, which has the assembly routines -changes to cpu.h, cpu.c, and stream_decoder.c to enable them -changes to configure.in to support the new cpu stuff -a preliminary Makefile.am -maybe something else I'm forgetting Now automake complains that configure.in

...it to work on other BSDs. However, I don't know what that would be, and I couldn't determine any safe way to do the check in Linux, nor do I have any way to test anything other than OS X. The altivec code itself should work on any platform with altivec. Regarding performance, command-line decoding will see a modest improvement, but it's really bottlenecked by the MD5 checking (and I don't have a clue as to how to optimize that). Real-time decoding should be improved substantially -- I've been meaning to test that and will get back to you with the results. -- Brady Patterson (bra...

Ok, the patch from 2003 about improving seeking still didn't make it to CVS, so here is another try. I made some benchmarking with the test_seeking utility from flac sources to show how bad the current seeking is, especially without seektable. Track used for the experiment had about 50 minutes. In the following table is average number of seeks and number of decoded frames required for one

My file is 3 hours long, so decoding takes around 5 minutes on an average computer. That is a bit too long unfortunately...

In case you would like to check another old patch, I have attached updated patch for seekable stream decoder, originally posted on 09/07/2003. -- Miroslav Lichvar -------------- next

Thank you for the feedback. This is cross-compiling for mingw-w64-x86_64 using gcc-5.3.0 and mingw-w64-4.0.4 on GNU/Linux. Upon attempting to compile now, a large number of errors occur in flac/decode.c which I have placed at the end of this email. They are eased by adding this to decode.c: #if _WIN32 #include <windows.h> #include <shlobj.h> #endif ...among the headers. Then, this

Hi All, We are using speex decoder only for narrow band decoding. Quite often, even though source frame is not silence, decoded audio is silence. I wonder there is a problem in the way we uses speex decoder API. Basically, we initialize speex decoder only once and just reset the decoder before we decoding another file. Do we need to intialize speex decoder and d...

...band decode is downshifted at the end. In this same version the wideband then upshifts the signal by the same amount. I would like to do away with the downshift on the narrowband side and the upshift on the wideband side and just past the decoded signal through. To do this and allow for the decoding of narrowband only signals I need to detect who the calling function is to the narrowband decode. What I was wondering is if there was already a member variable that held the current decode state. -Fritz Jean-Marc Valin wrote: >Could you explain a bit more what your question is? > &gt...

To avoid crash caused by an unbound LPC decoding when predictor order is larger than blocksize, the sanity check needs to be moved to the subframe decoding functions. --- src/libFLAC/stream_decoder.c | 30 ++++++++++++------------------ 1 file changed, 12 insertions(+), 18 deletions(-) diff --git a/src/libFLAC/stream_decoder.c b/src/libFLAC/str...

...Somehow, I couldn't get the original wav file back. I used both Speex ver 1.1.6 and ver 1.1.10 to both encode and decode, despite the same output file sizes, the output file from ver 1.1.10 decoder only lasts for a few seconds (the file is supposed to be a few minutes long). I have also tried decoding the wav file that was encoded with ver 1.1.10 encoder with ver 1.1.6 decoder and it works fine.. So I supposed the problem is in the ver 1.1.10 decoder. Have anyone experienced the same problem? Any suggestions or comments would be really appreciated Thanks heaps ______________________________...

...- 'packet decode' floor curves - 'packet decode' residues - synthesise I.e. a bit more highlevel structure to the docs would be cool and provide a lot of clarity. The lowlevel pseudocode is great and highly readable, but I did notice that somewhere halfway (after decoding the headers) the style changed quite a bit leading me to suspect two authors at work. * The second part (packet decode / synthesis) is the probably the hardest to read/understand, and some of the pseudocode is on the edge of difficult to grasp. * 7.2.2. header decode / 7.2.2.1. packet decode...
