amix filter is causing audio to disappear
21 novembre 2019, par MasonI’m trying overlay audio onto a video. I have a very simple ffmpeg command (
auido.mp3is much longer than the video)ffmpeg -i video.mp4 -i audio.mp3 -filter_complex "[0:a] [1:a] amix=duration=shortest [a]" -map 0:v -map [a] test.mp4This produces a silent video. However, when not mapping the video stream
ffmpeg -i video.mp4 -i audio.mp3 -filter_complex "[0:a] [1:a] amix=duration=shortest [a]" -map [a] test.mp4The resulting audio file is as expected.
What could be causing this issues ?
(Is there a better way to overlay audio onto a video via ffmpeg ?)

Anomalie #4401 (Nouveau) : Erreur bloquante avec sql_showtable() en sqlite
20 novembre 2019, par tcharlss (*´_ゝ｀)Glop,
(Constaté sur un SPIP 3.2.4)
La fonction spip_sqlite_showtable() renvoie un tableau incorrect pour `field` dans certains cas (cf. les clés `6` et `4` ci-dessous) :
var_dump(sql_showtable(’spip_billets_types’)) ;
array (size=2)
’field’ =>
array (size=18)
’id_billets_type’ => string ’INTEGER NOT NULL’ (length=16)
’id_billetterie’ => string ’bigint ( 21 ) NOT NULL DEFAULT 0’ (length=32)
’titre’ => string ’text NOT NULL DEFAULT "" COLLATE NOCASE’ (length=39)
’descriptif’ => string ’text NOT NULL DEFAULT "" COLLATE NOCASE’ (length=39)
’quota’ => string ’int ( 11 ) NOT NULL DEFAULT 0’ (length=29)
’prix’ => string ’decimal ( 20 ’ (length=13)
6 => string ’) NOT NULL DEFAULT 0’ (length=20)
’taxe’ => string ’decimal ( 4 ’ (length=12)
4 => string ’) NOT NULL DEFAULT 0’ (length=20)
’selection_min’ => string ’int ( 11 ) NOT NULL DEFAULT 0’ (length=29)
’selection_max’ => string ’int ( 11 ) NOT NULL DEFAULT 0’ (length=29)
’date_fin’ => string ’datetime NOT NULL DEFAULT "0000-00-00 00:00:00"’ (length=47)
’date_debut’ => string ’datetime NOT NULL DEFAULT "0000-00-00 00:00:00"’ (length=47)
’maj’ => string ’TIMESTAMP’ (length=9)
’composition’ => string ’varchar ( 255 ) NOT NULL DEFAULT ’’ COLLATE NOCASE’ (length=50)
’composition_lock’ => string ’tinyint ( 1 ) NOT NULL DEFAULT 0’ (length=32)
’rang’ => string ’int NOT NULL DEFAULT 0’ (length=22)
’id_profil’ => string ’bigint(21) NOT NULL DEFAULT 0’ (length=29)
’key’ =>
array (size=2)
’PRIMARY KEY’ => string ’id_billets_type’ (length=15)
’KEY id_billetterie’ => string ’CREATE INDEX `spip_billets_types_id_billetterie` ON `spip_billets_types` (
`id_billetterie`
)’ (length=94)Et voici ce qu’on devrait avoir, selon la vraie déclaration des champs :
’field’=> array( ’id_billets_type’ => ’bigint(21) NOT NULL’, ’id_billetterie’ => ’bigint(21) NOT NULL DEFAULT 0’, ’rang’ => ’int NOT NULL DEFAULT 0’, ’titre’ => ’text NOT NULL DEFAULT ""’, ’descriptif’ => ’text NOT NULL DEFAULT ""’, ’quota’ => ’int(11) NOT NULL DEFAULT 0’, ’prix’ => ’decimal(20,6) NOT NULL DEFAULT 0’, ’taxe’ => ’decimal(4,4) NOT NULL DEFAULT 0’, ’selection_min’ => ’int(11) NOT NULL DEFAULT 0’, ’selection_max’ => ’int(11) NOT NULL DEFAULT 0’, ’date_fin’ => ’datetime NOT NULL DEFAULT "0000-00-00 00:00:00"’, ’date_debut’ => ’datetime NOT NULL DEFAULT "0000-00-00 00:00:00"’, ’maj’ => ’TIMESTAMP’ ),Donc ça se plante sur les champs
prix_htettaxequi sont tous les 2 identiques :decimal(20,6) NOT NULL DEFAULT 0.
On dirait qu’il y a un souci soit quand il y a une parenthèse, soit quand il y a une virgule dans la déclaration d’une colonne.Du coup sur une table en Sqlite, la requête suivante ne passe pas :
sql_alter(’TABLE spip_billets_types CHANGE prix prix_ht decimal(20,6) NOT NULL DEFAULT 0’)
Car au moment de créer la table temporaire, la requête est erronée :2019-11-20 11:49:50 127.0.0.1 (pid 12659) :Pub:ERREUR : near "6" : syntax error - CREATE TABLE IF NOT EXISTS spip_billets_types_tmp ( id_billets_type INTEGER NOT NULL, id_billetterie bigint ( 21 ) NOT NULL DEFAULT 0, titre text NOT NULL DEFAULT "" COLLATE NOCASE, descriptif text NOT NULL DEFAULT "" COLLATE NOCASE, quota int ( 11 ) NOT NULL DEFAULT 0, prix_ht decimal(20,6) NOT NULL DEFAULT 0, 6 ) NOT NULL DEFAULT 0, taxe decimal ( 4 , 4 ) NOT NULL DEFAULT 0, selection_min int ( 11 ) NOT NULL DEFAULT 0, selection_max int ( 11 ) NOT NULL DEFAULT 0, date_fin datetime NOT NULL DEFAULT "0000-00-00 00:00:00", date_debut datetime NOT NULL DEFAULT "0000-00-00 00:00:00", maj TIMESTAMP, composition varchar ( 255 ) NOT NULL DEFAULT ’’ COLLATE NOCASE, composition_lock tinyint ( 1 ) NOT NULL DEFAULT 0, rang int NOT NULL DEFAULT 0, id_profil bigint(21) NOT NULL DEFAULT 0, PRIMARY KEY (id_billets_type))Allez, une petite une aspirine et je regarde la Regex qui décrypte la déclaration SQL :
/^[^(),]*\(((?:[^()]*\((?:[^()]*\([^()]*\))?[^()]*\)[^()]*)*[^()]*)\)[^()]*$/ -
I want to change the file name with exiftool. To “Result of adding time zone (+9) to CreateDate”
7 décembre 2019, par user3474300I shot a video with a sony camera.
A file with the extension .mp4 was created.
I want to change the shooting date and time to a file name.
The environment is Windows10.
What I tried
I first dragged and dropped the .mp4 video file to exiftool (-k) .exe.
ExifTool Version Number : 11.76
File Name : C0001.MP4
File Modification Date/Time : 2019:10:23 13:10:49+09:00

Track Create Date : 2019:10:23 04:10:32

Last Update : 2019:10:23 13:10:32+09:00
Creation Date Value : 2019:10:23 13:10:32+09:00I then typed the following command at a Windows 10 command prompt :
C:\hoge>"exiftool(-k).exe" -r "-FileNamehoge/C0001.MP4
Warning: Error removing old file - C:/hoge/C0001.MP4
1 directories scanned
1 image files updated
-- press RETURN --The following file was created.
2019-10-23_04-10-32 - C0001.MP4
How can I output the following file ?
I don’t know how to add time zone (+9) to CreateDate.
