These were used because the entropy coder originally came from outside libcelt, and thus did not have a common type system. It's now undergone enough modification that it's not ever likely to be used as-is in another codec without some porting effort, so there's no real reason to maintain the typedefs separately. Hopefully we'll replace these all again somed...

When I removed the special case for EC_ILOG(0) in commit 06390d082dcdfa8addb3dde337543bc0f0ebae44, it broke ec_dec_uint() with _ft=1 (which should encode the value 0 using 0 bits). This feature was tested by ectest.c, but not actually used by libcelt. An assert has been added to ec_dec_uint() to ensure that we don't try to use this feature by accident. ec_enc_uint() was actually correct, but support for this feature has been removed and the assert put in its place. --- libcelt/entdec.c | 3 +++ libcelt/entenc.c | 4 +++- tests/ecte...

Hello everyone, I have been having trouble utilizing the PLC function (I think). In older versions (0.7.1) a pointer to NULL did the trick, but with code from the tip of the GIT repository, this method causes the codec to crash on the C55x fixed point platform. I have not determined where the crash occurs. I have also attempted to pass in an array of zero's and this creates an echoey, reverby

HiI'm trying to run CELT on Win32 but I'm running into some corrupted stack errors when using alloca(). When get_required_bits32() (in file cwrs.c:308) is called from get_required_bits() (in file cwrs.c:328) the 'K' parameter is 1 which means that the uint32 which is allocated on the stack only has 3 bytes instead of 4. This results in a corrupted stack in the following call to

Hi, I am a newbe here, so I hope I am not asking something crazy. I was looking on the Celt downloads and I noticed that the latest command line builds were for version 0.6. I know it is still early in development, and that the devs probably don't have time for developing CL versions for everything. since I know nothing about sourcecode and whatnot, I was wondering if there was a fairly simple

...'restrict' keyword. It does have __restrict which appears to be slightly different - http://msdn.microsoft.com/en-us/library/5ft82fed(VS.80).aspx. If it's too much trouble to get it to compile with VS, are there any prebuilt .lib files availble? The celt_060_tools_win32.zip contains a libcelt-0.dll but it's out of date ( and I don't have the corresponding .def file ). Thanks- John ?

Hi. I am glad to inform everyone here that support for decoding using libcelt was just pushed to ffmpeg. It raised a few API questions or issues: * At least while it's experimental, having a constant in the library for the supported bitstream version would probably be useful. Something like that comes to mind: extern celt_int32 celt_bitstream_version; or, eve...

Hi, I am facing problem when using CELT for iPad. I wonder if someone have experience with that, or someone have idea why it happened. I was able to compile libCelt (and lib Ogg) for iPad (iOS 4.2) and for iPad Simulator I added those libraries to my application, and it was successfully compiled and linked, but once the application start it immediately crash (even if I am not using any of the CELT functions) this is how the libraries were configured ... #iP...

I am working on a project that transports audio in realtime from a linux box to a windows box throuh libcelt. The windows client program is written in C# and C++ and I therefore need the celt library in its most recent version (0.7) to be able to compile in Visual Studio 2008. In order to do this I, as I understand it, need a .vcproj file for the project. Are there any plans on making such a file and ma...
