  • Ajouter notes et légendes aux images

    7 février 2011, par

    Pour 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 (...)

  • Organiser par catégorie

    17 mai 2013, par

    Dans MédiaSPIP, une rubrique a 2 noms : catégorie et rubrique.
    Les différents documents stockés dans MédiaSPIP peuvent être rangés dans différentes catégories. On peut créer une catégorie en cliquant sur "publier une catégorie" dans le menu publier en haut à droite ( après authentification ). Une catégorie peut être rangée dans une autre catégorie aussi ce qui fait qu’on peut construire une arborescence de catégories.
    Lors de la publication prochaine d’un document, la nouvelle catégorie créée sera proposée (...)

  • Very slow writes on MySQL 8 - waiting for handler commit

    23 mai 2023, par Akshat Goel

    I have MySQL 8 docker installation installed on an edge device which has the following two tables to write to

    


    video_paths | CREATE TABLE `video_paths` (
  `entry` int(11) NOT NULL AUTO_INCREMENT,
  `timestamp` bigint(20) NOT NULL,
  `duration` int(11) NOT NULL,
  `path` varchar(255) NOT NULL,
  `motion` int(11) NOT NULL DEFAULT '0',
  `cam_id` varchar(255) NOT NULL DEFAULT '',
  `hd` tinyint(1) NOT NULL DEFAULT '0',
  PRIMARY KEY (`entry`),
  KEY `cam_id` (`cam_id`),
  KEY `timestamp` (`timestamp`)
) ENGINE=InnoDB AUTO_INCREMENT=7342309 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci


    


    AND

    


    CREATE TABLE `tracker` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `table_name` varchar(255) NOT NULL,
  `primary_key_name` varchar(255) NOT NULL,
  `pointer` int(11) NOT NULL DEFAULT '0',
  PRIMARY KEY (`id`),
  UNIQUE KEY `table_name` (`table_name`)
) ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci


    


    The following queries are run every few secs for up to 32 cameras and are taking a lot of time as indicated by the slow query log.

    


    UPDATE tracker SET pointer = 7342046 WHERE table_name = 'video_paths'

INSERT INTO video_paths (timestamp,duration,path,cam_id,hd) VALUES (1597548365000,5000,'/s/ss/x-0/v/2020-08-16/3/1.ts','x-1',1)



    


    Most of the time is spent in the waiting for handler commit state

    


    The total size of my data (tables + index) is 1GB and I have the following settings enabled to optimise for write

    


    skip-log-bin - Disabled the bin log because I don't have a replica and therefore no use for it
innodb_flush_log_at_trx_commit =2 - I am Optimising for performance rather than consistency here.
range_optimizer_max_mem_size =0 As mention in this question, I have allowed max memory to range optimiser.
inndo_buffer_pool_size= 512Mb - This should be enough for my data ?.
    
innodb_log_file_size= 96Mb *2 files

    


    I am seeing queries that are taking up to 90-100 secs sometimes.

    


    SET timestamp=1597549337;
INSERT INTO video_paths (timestamp,duration,path,cam_id,hd) VALUES (1597548365000,5000,'/s/ss/x-0/v/2020-08-16/3/1.ts','x-1',1);
# Time: 2020-08-16T03:42:24.533408Z
# Query_time: 96.712976  Lock_time: 0.000033 Rows_sent: 0  Rows_examined: 0


    


    ---UPDATE---
Here's the complete my.cnf file

    


    my.cnf

[mysqld]
pid-file        = /var/run/mysqld/mysqld.pid
socket          = /var/run/mysqld/mysqld.sock
datadir         = /var/lib/mysql
secure-file-priv= NULL
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0

skip-log-bin
innodb_buffer_pool_size=536870912
innodb_log_file_size=100663296

# Custom config should go here
!includedir /etc/mysql/conf.d/

conf.d/docker.cnf 
[mysqld]
skip-host-cache
skip-name-resolve 


    


    The docker container is using the host mode so complete 15GB memory is available to the container.

    


    --- UPDATE 2 ---
After increasing the innodb_buffer_pool_size to 2GB as suggested by @fyrye, the statements have now started getting stuck on STATE = UPDATE instead of waiting for handler commit.

    


    ---- UPDATE 3 ---
Looks like the CPU is causing the bottleneck

  • ffmpeg command execution never stops

    19 août 2020, par Khawar Raza

    I am trying to concatenate 3 videos of different resolutions and overlaying 2 videos as transition effects(though the chroma key color removal is not yet implemented) between videos using below command :

    


    ffmpeg 
-i input1.mp4 
-i input2.mp4 
-i input3.mp4 
-i transition1.mp4 
-i transition2.mp4 
-filter_complex 
"[0:v]pad=width=1080:height=1920:x=(1080-iw)*0.5:y=(1920-ih)*0.5:color=black[video0];
[1:v]pad=width=1080:height=1920:x=(1080-iw)*0.5:y=(1920-ih)*0.5:color=black[video1];
[2:v]pad=width=1080:height=1920:x=(1080-iw)*0.5:y=(1920-ih)*0.5:color=black[video2];
[video0][video1][video2]concat=n=3:v=1:a=0[outv];
[3:v]scale=w=1080:h=1920[t0];
[4:v]scale=w=1080:h=1920[t1];
[outv][t0]overlay=enable='between(t,6.6045,9.6335)'[out0];
[out0][t1]overlay=enable='between(t,12.5655,15.6165)'[out1];
[0:a][1:a][2:a]concat=n=3:v=0:a=1[audio]" 
-c:v libx264 -pix_fmt yuv420p -map [out1] -map [audio] -preset ultrafast output.mp4


    


    I get success only with few videos. Most of the times the command execution never stops. It keeps on appending something to the output video file even for hours. Here is the output from console :

    I even tried command without overlay and audio parts but result was same. I am working on Android app and using below ffmpeg wrapper library :

  • FFMpeg - Overlay not being shown when enable=between parameter is added

    19 août 2020, par Khawar Raza

    I am using below command to add transitions effect between videos using overlays such that when one videos is about to finish, the overlay gets visible. Before showing overlays, I have to add padding and concatenate videos make one single video and then display overlays. :

    


    ffmpeg 
-i input1.mp4 
-i input2.mp4 
-i input3.mp4 
-i transition1.mp4 
-i transition2.mp4 
-filter_complex 
"[0:v]pad=width=1080:height=1920:x=(1080-iw)*0.5:y=(1920-ih)*0.5:color=black[video0];
[1:v]pad=width=1080:height=1920:x=(1080-iw)*0.5:y=(1920-ih)*0.5:color=black[video1];
[2:v]pad=width=1080:height=1920:x=(1080-iw)*0.5:y=(1920-ih)*0.5:color=black[video2];
[video0][video1][video2]concat=n=3:v=1:a=0[outv];
[3:v]colorkey=0x00d800:0.1[t0];
[t0]scale=w=1080:h=1920[tr0];
[4:v]colorkey=0x00d800:0.1[t1];
[t1]scale=w=1080:h=1920[tr1];
[outv][tr0]overlay=0:0:enable='between(t\,7\,9)'[out0];
[out0][tr1]overlay=0:0:enable='between(t\,12\,15)'[out1];
[0:a][1:a][2:a]concat=n=3:v=0:a=1[audio]" 
-vsync 0 -c:v libx264 -pix_fmt yuv420p -map [out1] -map [audio] -preset ultrafast output.mp4


    


    But above command does not show any overlay video. If I remove enable=between(t, start, end) from overlay parameters, all the overlay gets displayed at video start. I am very beginner to video editing and to FFMpeg. Can anybody guide me what I am doing wrong here ?
