From: Lasse Collin <lasse.collin@tukaani.org> Return value of rc->fill() is checked in rc_read() and error() is called when needed, but then the code continues as if nothing had happened. rc_read() is a void function and it''s on the top of performance critical call stacks, so propagating the error code via return values doesn''t sound like the best fix. It seems better

From: Lasse Collin <lasse.collin@tukaani.org> The code assumes that the input is valid and not truncated. Add checks to avoid reading past the end of the input buffer. Change the type of "skip" from u8 to int to fix a possible integer overflow. Signed-off-by: Lasse Collin <lasse.collin@tukaani.org> Signed-off-by: Jan Beulich <jbeulich@suse.com> ---

For more information: http://www.publicsource.apple.com/projects/streaming/ I know that a QuickTime Component of Ogg Vorbis (compressor/decompressor) in progress. (Thanks guys) Could I stream Ogg Vorbis with Darwin Streaming Server? Is a Packetizer and Reassembler available (under develope)?

...to prevent clearing the > currently used IDT, move the IDT to the data segment. Ugh. At the very least this needs a comment in the code. I had a patch to fix the kernel ELF loader to clear BSS, which would fix this problem once and for all, but it didn't work due to the messy way that the decompressor handles memory. I never got around to fixing this, sadly.

Good news all! I now have a functional version of the Quicktime Component of the Ogg Vorbis decompressor. In English: this extension will allow all Quicktime apps to play .oggs (including iTunes). I plan on posting it ASAP. I have a few problems with memory that I'd like to get cleared up first. I plan on carbonizing it as soon as it functions in classic. I'll also do a Winders version. --...

Linux 3.11 added respective support, so I think we should follow suit. 1: xen: add LZ4 decompression support 2: libxc: add LZ4 decompression support Signed-off-by: Jan Beulich <jbeulich@suse.com>

The major new feature in 1.0d3 is the addition of an importer and a sound decompressor. This means that MacOS X and Win32 users can play sounds. MacOS 9 users will need to wait a bit more (or help me with the project) as the sound decompressor has an additional requirement that it may not allocate memory while decompressing. Some work needs to be done on the vorbis libraries to mee...

...nverter" can't do the conversion to YV12. 3. I found that the ffdshow raw video filter should be able to do this conversion (although I'd like to have no dependencies other than Theora and Speex). 4. When I render the Theora decode filter's output pin, DirectShow attaches an AVI decompressor, a color space converter and finally the video renderer. 5. I cannot play the filter graph. When trying to do so, GraphBuild shows: "This graph can't play", return code 0x80070000. 6. I tried to replace the AVI decompressor and the color space converter with another ffdshow raw vide...

Hello. I am trying to find a way to retrieve data from Harvard Dataverse website. I usually don't have problem in web-scraping data but the problem here is that there are a bunch of data formats such as .tab, .7z and so and I just can't find a way to retrieve the data I am interested in woth an unique solution. Any hint? [[alternative HTML version deleted]]

I would hope the any sane loader would clear BSS before executing anything. This isn?t currently the case, though....
