Monitoring de fermes de MediaSPIP (et de SPIP tant qu’à faire)
31 mai 2013, parLorsque l’on gère plusieurs (voir plusieurs dizaines) de MediaSPIP sur la même installation, il peut être très pratique d’obtenir d’un coup d’oeil certaines informations.
Cet article a pour but de documenter les scripts de monitoring Munin développés avec l’aide d’Infini.
Ces scripts sont installés automatiquement par le script d’installation automatique si une installation de munin est détectée.
Description des scripts
Trois scripts Munin ont été développés :
1. mediaspip_medias

Ajouter notes et légendes aux images
7 février 2011, parPour pouvoir ajouter notes et légendes aux images, la première étape est d’installer le plugin "Légendes".
Une fois le plugin activé, vous pouvez le configurer dans l’espace de configuration afin de modifier les droits de création / modification et de suppression des notes. Par défaut seuls les administrateurs du site peuvent ajouter des notes aux images.
Modification lors de l’ajout d’un média
Lors de l’ajout d’un média de type "image" un nouveau bouton apparait au dessus de la prévisualisation (...) -
Automated installation script of MediaSPIP
25 avril 2011, parTo overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
The documentation of the use of this installation script is available here.
The code of this (...)

libx265 motion compensation and CU traverse
17 juin 2016, par ArianaI’m trying to play with the H.265 motion compensation and search (HEVC- libx265 implementation from here : https://bitbucket.org/multicoreware/x265/downloads). I need to slightly extend the edge extension search, and fill the macro block with left-most pixels as if my sample videos are like cylinder (rightmost is connected to leftmost).
What I need to do is basically this :
One way to do that is to modify the edge extension area (which is already in the code, in the
frameFilter.cpp
), and do that for rightmost and fill parts of blocks which are out with leftmost pixels. I identified the piece of code here which apparently is responsible for that. Can someone help me with implementing this feature ?if ((col == 0) | (col == m_frameFilter->m_numCols - 1))
{
// TODO: improve by process on Left or Right only
primitives.extendRowBorder(reconPic->getLumaAddr(m_rowAddr), stride, reconPic->m_picWidth, realH, reconPic->m_lumaMarginX);
if (m_frameFilter->m_param->internalCsp != X265_CSP_I400)
{
primitives.extendRowBorder(reconPic->getCbAddr(m_rowAddr), strideC, reconPic->m_picWidth >> hChromaShift, realH >> vChromaShift, reconPic->m_chromaMarginX);
primitives.extendRowBorder(reconPic->getCrAddr(m_rowAddr), strideC, reconPic->m_picWidth >> hChromaShift, realH >> vChromaShift, reconPic->m_chromaMarginX);
}
}
// Extra Left and Right border on first and last CU
if ((col == 0) | (col == m_frameFilter->m_numCols - 1))
{
copySizeY += lumaMarginX;
copySizeC += chromaMarginX;
}
// First column need extension left padding area and first CU
if (col == 0)
{
pixY -= lumaMarginX;
pixU -= chromaMarginX;
pixV -= chromaMarginX;

Revision 9f5fd31d7f : Expand UMV border to 96 pixels Ensures that the full 64 pixel border is availab
29 avril 2013, par John KoleszarChanged Paths :
Modify /vpx_scale/yv12config.h
Expand UMV border to 96 pixelsEnsures that the full 64 pixel border is available for prediction (need a
minimum of
64+INTERP_EXTEND on all sides, and 32+INTERP_EXTEND on UV). Value also must be a
multiple of 32 to keep UV stride alignment. The smaller border was causing the
prediction
to read outside the frame, which can cause a mismatch.TODO : Get rid of this explicit border and use edge emulation instead.

vp9 : Add bsf to fix reordering in raw streams
9 janvier 2017, par Mark Thompsonvp9 : Add bsf to fix reordering in raw streams
Takes a raw input stream containing frames with correct timestamps but
possibly out of order and inserts additional show-existing-frame
packets to correct the ordering.(cherry picked from commit 34e051d16850701694410a0e72e0e4ff3a5ec293)
(cherry picked from commit b43b95f4789b6e60f9684918fd3c0a5f3f18aef6)Also converted from bitstream to get_bits.
