Well, I've read that there have been bugs in valgrind, were SSE optimized versions of strlen() do guaranteed safe overreads of memory, but valgrind wasn't aware the overreads were safe. Anyway, it seems easy to

Well, I sent this earlier this week, but I guess it's stuck in the spam filter, so I'll send it again split up in several parts. First the full source, if this one arrives I'll reply with the patch. Ok, so I ended up creating 2 versions of this. The first one is what I mentioned earlier, pretty much a line-for-line translation of the original example. The c++-style casts made the

Well, I have been away a couple of days, so I don't know if I'm in time, but I reported a memory leak and submitted a patch a couple of months ago. It would be nice if it can make it in. I first reported the leak here: http://lists.xiph.org/pipermail/flac-dev/2011-August/003002.html And the patch is here:

Well, unless somebody has a brilliant idea, I am giving up on this. I don't see how I can do what I wanted to. The slightly hacky way I thought would work, was by guaranteeing the read_callback could read at least enough data to make process_single() return (ie the buffer should contain at least 1 frame or block). But it seems that even when the maximum frame size is known, that can never be

Yeah sure! I don't get

Hi! I think this patch adds the last of the libFLAC metadata functions to the correct classes in libFLAC++. This is 4 CueSheet member function and 1 Picture function. If I haven't looked properly and more functions are still missing, let me know. Next I would like to maybe add a few convenience functions. For instance, a padding block can really only be created and given a size, but this

Hi! Attached is a tiny patch adding a convenience function to create a Metadata::Padding object with a certain size in one statement. In a previous message I mentioned writing some more convenience functions, but on closer inspection they would either be inefficient or very difficult to implement. I have also nearly finished converting the cpp file-encode example to use the C++ api, and will

Ok, so I ended up creating 2 versions of this, I hope the attachments aren't too big. The first one is what I mentioned earlier, pretty much a line-for-line translation of the original example. The c++-style casts made the (already ugly) lines with casts even uglier by the way... The difference in the second version is that the metadata objects are no longer heap-allocated. This is more in

Hi, I was just messing around with a metadata modifier in flac (using the C++ api) and found something strange. When iterating over a chain and calling FLAC::Metadata::Iterator::get_block(), it seems a newly constructed ProtoType* is returned (the source says "return local::construct(::FLAC__metadata_simple_iterator_get_block(iterator_));"), if one does not delete this pointer, the

The attached patch adds the missing FLAC__metadata_object_seektable_*() functions from FLAC's metadata object methods (FLAC/metadata.h) to FLAC++'s SeekTable class. Of the 11 functions in the C API, only 4 are currently in the C++ API, this patch adds the missing 7. If this patch is ok, VorbisComment will be next. A quick look tells me only 5 out of 13

Hi! I've been using a little C++ program I've written to encode flac files. The program does this in the usual way (I think), by inheriting a class from FLAC::Encoder::File, and passing it chunks of raw samples through process_interleaved()... Anyway, the program works beautifully, and I've now decided to try and add some metadata to the encoded flacs. Eventually, there will be vorbis

During my current dealings with the FLAC library I think I discovered a memory leak. After an encoder stream has finish()'ed, I believe you are supposed to use it again by calling init(). However, when verification is enabled, the init() routine will create a new stream decoder (to verify the data) without deleting (or reusing) the existing one. A small program demonstrating this is pasted

Hi! I am working on an application that reads audio data from files, and runs it through some user defined filters. The filters basically all derive from some base filter and have methods start(), update() and finish(). The start routine performs any initialization required by the filter, and finish() does the clean up. In between, I simply read the file piece by piece into a buffer using

Attached is a patch that adds 5 missing FLAC__metadata_object_vorbiscomment_* functions to the VorbisComment class. In my previous message I stated 8 functions were missing, but on closer inspection, 3 of those belong in the VorbisComment::Entry class, and 2 of them already have equivalent functions in there. The last one (FLAC__metadata_object_vorbiscomment_entry_matches()) does not, but I have
