FFmpeg sws_scale on changed area
1er octobre 2016, par useprxfI was using
sws_scale
to convert a group of RGB32 images to YUV420 format. Each image is very similar to the previous one and they only differ on a rectangle region Q.My question is how to utilize Q to speed up the conversion process ? An additional parameter should be added to
sws_scale
function.sws_scale( ctx, in_plane, in_stride, sliceY, height, out_plane, out_stride, Q){
// parameter out_plane stores the YUV420 data of previous image
Instead of scanning the whole image, scan through rectangle Q{
Do conversion

How to fix 'ffmpeg server returned 403 forbidden (access denied) ?
1er février, par peppahI'm writing a website to convert youtube videos using NodeJS. I am using a package to convert them (horizon-youtube-mp3). The package works, however, I'm having problems converting. Whenever I try to convert a youtube link, it will return 'server returned 403 forbidden access'. 
This error happens in 95% of the links. Some links actually work and convert correctly, but only a few.



I tried running the script on 3 different computers running 3 different OS's. My VPS, my laptop and my home PC. I looked on the web but couldn't find anything useful.



So yeah, I completely suck since I really don't understand why one video would convert, and the other won't. Even if the region of the video is the same.



Any help would be highly appreciated !

Anomalie #3260 (Nouveau) : Problème de dump sur les tables comportants des index de longueur spéci...
28 août 2014, par b bLe contexte est le suivant : http://contrib.spip.net/GIS-4?debut_comments-list=@476655#forum476655
En résumé, depuis que la table spip_gis contient des index dont la longueur est spécifiée, le système de dump génère une erreur sur ces tables. Après pas mal de recherche, je suis remonté jusqu’à
spip_mysql_show_table()
(raison pour laquelle ce ticket est déclaré sur le core et non le plugin dump).J’ai d’abord étudié ce qui se passe dans
base_copier_table()
de ecrire/base/dump.php :http://core.spip.org/projects/spip/repository/entry/spip/ecrire/base/dump.php#L536
À ce niveau, dans
$desc_source['key']
la longueur des index n’est pas renseignée. Si on compare le contenu des fichiers de cache des descriptions des tables, on observe que tmp/cache/sql_desc*.txt ne renseigne pas la longueur des index. Alors que tmp/cachesql_desc_dump*.txt est ok, la longueur des index y est présente.Du coup, j’en suis remonté à
sql_showtable()
, et plus précisemment àspip_mysql_show_table()
:http://core.spip.org/projects/spip/repository/entry/spip/ecrire/req/mysql.php#L754
Depuis phpmyadmin, un
SHOW CREATE TABLE
renvoie bien ce qu’il faut, ex :CREATE TABLE `spip_gis` ( `id_gis` bigint(21) NOT NULL AUTO_INCREMENT, `titre` text NOT NULL, `descriptif` text NOT NULL, `lat` double DEFAULT NULL, `lon` double DEFAULT NULL, `zoom` tinyint(4) DEFAULT NULL, `adresse` text NOT NULL, `pays` text NOT NULL, `code_pays` varchar(255) NOT NULL DEFAULT ’’, `region` text NOT NULL, `departement` text NOT NULL, `ville` text NOT NULL, `code_postal` varchar(255) NOT NULL DEFAULT ’’, PRIMARY KEY (`id_gis`), KEY `lat` (`lat`), KEY `lon` (`lon`), KEY `pays` (`pays`(500)), KEY `code_pays` (`code_pays`), KEY `region` (`region`(500)), KEY `ville` (`ville`(500)), KEY `code_postal` (`code_postal`), KEY `departement` (`departement`(500)) ) ENGINE=MyISAM AUTO_INCREMENT=24 DEFAULT CHARSET=latin1
Il semble que la regex de la ligne 736 ne match pas la table
spip_gis
certainement à cause des(500)
:http://core.spip.org/projects/spip/repository/entry/spip/ecrire/req/mysql.php#L736
Et du coup, on bascule sur le plan B, qui ne fait qu’un simple
SHOW COLUMNS FROM
ne contenant pas l’information de longueur des index :http://core.spip.org/projects/spip/repository/entry/spip/ecrire/req/mysql.php#L765
Wala où j’en suis ^^ Je ne sais pas si ce comportement est voulu, mais il pose un sacré problème pour les dumps.
