[LLVMdev] [PATCH / PROPOSAL] bitcode encoding that is ~15% smaller for large bitcode files...
Hi all,
I've been looking into how to make llvm bitcode files smaller. There is
one simple change that appears to shrink linked bitcode files by about 15%.
See this spreadsheet for some rough data:
https://docs.google.com/spreadsheet/ccc?key=0AjRrJHQc4_bddEtJdjdIek5fMDdIdFFIZldZXzdWa0E
The change is in how operand ids are encoded in bitcode files. Rather than

Storing FLAC in Matroska
Hello,
I'm looking into storing FLAC audio in Matroska and I have a few
questions.
1. Can I use libflac to extract the compressed frames?
Or will I need to write up a simple file parser?
2. What is required to decode the frames?
From the docs I understand that you need the FRAME and you may need the
METADATA_BLOCK.
Thanks,

METADATA_BLOCK_PICTURE question
Hi everybody,
I have a question about the following part of the METADATA_BLOCK_PICTURE
specification. The components: Width, Height, Color Depth, and Colors
Used don't provide an "unknown" value and seem to assume that the
program encoding the METADATA_BLOCK will be aware of these components of
the file.
As these fields seem to just provide "extra" information (I'm

Storing FLAC in Matroska
First, Thank you for your answers.
I using the following code to try simply decode a flac file and write the
decoded data raw PCM file. The resulting file is just noise and pops, so is
the decoded data in a different format than PCM?
struct flacData {
FILE *inputFile;
FILE *outputFile;
char *filename;
};

No. this in incorrect. The VorbisComment

I'm not sure I understand your question, but one unfortunate
fact about native FLAC is that you cannot discover the frame

The latest version of my cue+wav splitter supports .flac files. Hope to

It also supports .shn and .ape. I've seen shorten

Flac] Where Cover Art?
OK Martin. Thank you for the explanations and for your time.
I am writing a program that reads and writes all existent Tags types. It
lacks only to end the edition (rewriting) of "Native" Flac and Matroska.
Both cases for the same problem: the separation of Tags and Picture in
different blocks. In Flac I resolved it, but now I have to add

Flac] Where Cover Art?
You said "With the exception of where to put a picture file, VorbisComments
in a Vorbis stream are the same as VorbisComments in a FLAC stream."
In METADATA_BLOCK_PICTURE case they would not be the same. Up to now we
could exchange the complete block of VorbisComments. But with the addiction
of METADATA_BLOCK_PICTURE doesn't happen this way.
In Ogg files the METADATA_BLOCK_PICTURE

reassessing the HCL ratings scale
Here is our current rating scale for the HCL:

2 = based on fragments of publicly available protocol
3 = based on publicly available protocol
4 = vendor provided protocol
5 = vendor provided protocol and hardware
I was going to suggest a few changes to the ratings we have assigned (for instance, not having a rating of "5" with an

Tag flac as flac 1.2.1_git
I seem to recall that changes in the second number indicated a minor change
in the *format* of the file itself (for example, 1.1.x to 1.2.x introduced
a new rice coding option used for 24-bit files). Are there any format
changes that would justify that ? Otherwise, 1.2.2 would seem more
appropriate, not to minimize the work that you are doing...
Cheers,
Pyt.

We added a DNS entry to Samba via the Windows DNS Manager which apparently
was invalid. Now we can't see the list of forward lookup in the Window DNS
Manager because it immediately errors and we have to restart the Samba
service.
