Building a new decoder - some questions on the spec (residue decode)
Hi I am trying to build a new decoder in Java, I know there are a couple of java decoders already but they don't implement the bit of the spec I am having questions on Question 1) In section 8.6.2 it mentions "However, it is also possible to set [residue_begin] and [residue_end] to specify a range partially or wholly beyond the maximum vector size. Before beginning residue decode,

Vorbis encoding at half speed
Echoing Hiroka, who is likely on the right track. Simply telling the encoder 'one channel' and then passing stereo data will not convert the stereo data to mono. The encoder encodes whatever it is given...

A few questions about libvorbis from a newbie
Hello Martin, > how a number of samples with no defined size is translated into 8, 16, or 32 bit values in my buffer Although I do not know in detail about the actual implementation of libvorbis, most of the decoders should internally produce single-precision (32bit) floating point values, or 32bit integers as the result of PCM decoding. They are downcast to PCM samples with 8bit, 16bit, or

Vorbis encoding at half speed
Hello Ross, The attachment appears at least to me as a valid monaural Vorbis audio. It says in its header that there is only one audio channel, no stereo mapping is in use, and there is only one audio vector per frame. Actually it does not sound well, in a way that makes me wonder if two channels are unexpectedly merged into one... (thus it might sound like half-speed) I guess there is

A few questions about libvorbis from a newbie
I am deeply sorry about the corrupt message just being sent; there seems to have been a compatibility issue with my mailer and my browser. This is an identical copy of the previous message: Hello Martin, Vorbis encoders are lossy, which is in a sense equivalent to converting the sample size of the raw PCM stream into something that would result in the desired bitrate. The "sample size"

Vorbis encoding at half speed
I’m using a Windows development component which uses vorbis.dll, ogg.dll, vorbisenc.dll for encoding an Ogg Vorbis file. It's all working well except for one user occasionally has a 1 hour file appear as 2 hours and it plays at half speed. It is being converted from stereo to mono before feeding the encoder with a channels=1 configuration. Here is an example file which will be available for

Problems with dovecot/sendmail combi.
Hi, I am really stuck here. I am trying to setup imap for an external mail server. I have a freebsd server running sendmail / dovecot. I am transfering the existing mail from an exchange 2003 server to the mailserver using imapsync. This works fine, but gives errors when it tries to make a submap, also thunderbird gives an error "Mailbox doesn't allow inferior mailboxes" when I try

Help understand decoding of stereo vorbis data
Hi, I'm trying to implement a vorbis decoder, and am having some trouble getting it to work with stereo vorbis data. It's giving me some PCM output which is roughly right, but it has artefacts. I think it's most likely something to do with my handling of floor decode/curve synthesis. My first thoughts are that I'm handling the submap number/floor mapping incorrectly; I'm

A few questions about libvorbis from a newbie
Sorry about the personal reply Ian. I hope keeping the subject the same is the way to reply to the list (I have never used a mailing list before). The last thing I am not grasping is how *pcm_total *works without a concept of sample size? If the sample size is whatever I decide to read it as, how does it calculate the number of samples (of one channel I'm assuming because we have to multiply

[PATCH libnbd 2/2] api: Implement local command with systemd socket activation.
This adds new APIs for running a local NBD server and connecting to it using systemd socket activation (instead of stdin/stdout). This includes interop tests against nbdkit and qemu-nbd which I believe are the only NBD servers supporting socket activation. (If we find others then we can add more interop tests in future.) The upstream spec for systemd socket activation is here:

This neutral refactoring adds -DTLS_MODE. We can in future change the requested TLS mode, but not in this commit. It also checks that nbd_get_tls_negotiated returns true after connecting, when the requested mode was set to LIBNBD_TLS_REQUIRE. --- interop/Makefile.am | 4 ++++ interop/interop.c | 26 ++++++++++++++++++++------ 2 files changed, 24 insertions(+), 6 deletions(-) diff --git

[RFC] Make LoopVectorize Aware of SLP Operations
Hello, We would like to propose making LoopVectorize aware of SLP operations, to improve the generated code for loops operating on struct fields or doing complex math. At the moment, LoopVectorize uses interleaving to vectorize loops that operate on values loaded/stored from consecutive addresses: vector loads/stores are generated to combine consecutive loads/stores and then shufflevector

[RFC] Make LoopVectorize Aware of SLP Operations
Hi Florian! This proposal sounds pretty exciting! Integrating SLP-aware loop vectorization (or the other way around) and SLP into the VPlan framework is definitely aligned with the long term vision and we would prefer this approach to the LoopReroll and InstCombine alternatives that you mentioned. We prefer a generic implementation that can handle complicated cases to something ad-hoc for some

[PATCH 3/3] v2v: vdsm: add --vdsm-fixed-ovf option
Add option for -o vdsm that enables output of the modified OVF. oVirt engine should already be able to consume the OVF, but let's not take any chances and enable it only by command line argument. It can be made default later when it receives proper testing. Signed-off-by: Tomáš Golembiovský <tgolembi@redhat.com> --- v2v/cmdline.ml | 5 +++++
