Un peu de ffmpeg

Créer une vidéo avec une liste d'images/photos :

Sous Linux:

cat *.jpg | ffmpeg -f image2pipe -r 1 -vcodec mjpeg -i - -vcodec libx264 out.mp4

 

Sous Windows:

ffmpeg -r 1/5 -i gmic_pencilbw_000000_000%03d.png -c:v libx264 -vf fps=25 -pix_fmt yuv420p out.mp4

Créer l'image du spectre audio d'un fichier audio ou vidéo:

ffmpeg -y -i tets.mp3 -lavfi showspectrumpic=s=1200x600:fscale=log:color=rainbow spectrum.png

 

 

Encodage NVIDIA:

ffmpeg -i "e:\input.ts" -vcodec h264_nvenc -preset slow -level 4.1 -qmin 18 -qmax 22 "e:\output.mp4"

Ou bien :


ffmpeg -loglevel debug -threads 4 -hwaccel cuvid -c:v mpeg2_cuvid -i "e:\input.ts" \
-filter:v scale_npp=w=1920:h=1080:format=yuv420p:interp_algo=lanczos \
-c:v h264_nvenc -preset:v llhq -profile:v main -level:v 4.1 -rc:v ll_2pass_quality -rc-lookahead:v 32 -temporal-aq:v 1 -weighted_pred:v 1 -coder:v cabac \
-f mp4 "e:\output.mp4" 

Windows 10 : Utilisation simultané d'une connexion Ethernet pour le LAN et d'une connexion 4G ou autre pour le WAN

 Suite à une panne de box, j'ai eu recours à mon téléphone portable pour utiliser Internet.

J'ai autorisé le partage par USB sur mon téléphone, connecté celui-ci au PC, mais ça ne fonctionné pas car ma connexion Ethernet été toujours active, si je désactivais cette connexion Ethernet, l'accès à Internet était possible mais alors plus d'accès au réseau local (NAS, etc... )

La solution trouvé ici (et ailleurs) : connexion simultanée wifi et ethernet win10 (pcastuces.com)

Panneau de config -> Centre Réseau et partage -> sur la gauche Modifier les param de carte

1. Clic droit sur la carte a faire passer en priorité haute (Ethernet) -> Propriétés
2. Sélectionnez Protocole Internet version 4 -> propriétés
3. Bouton « Avancé… » tout en bas
4. Décochez ensuite Métrique automatique et entrez une métrique de l’interface a 1
5. Répétez ces étapes pour l'interfaces 4G (ou freewifi) mettant 2 en métrique sachant que plus la métrique est haute moins la carte est prioritaire

Par exemple: Connexion 4G en "10" et connexion Ethernet en "20"

Maintenant il est possible accéder au deux réseaux !

 MPD et les streams Radio France

J'utilise MPD sur un raspberry conjointement avec l'interface web mympd.

J'écoute principalement des streams de Radio France en haute qualité (AAC 192 kbs) et depuis quelques semaines et le matin seulement je constate des coupures du son voir l'abandon par MPD du stream qui passe au suivant de la playlist.

J'ai corrigé ce problème en remplacent le plugin d'entrée curl par ffmpeg

J'ai modifier le plugin d'entrée:

input {
        plugin "ffmpeg"

}

#input {
#        plugin "curl"

#}

... et ça ne résou rien :(

J'ai regardé les paquets TCP échangés. 

J'ai remarqué que le dns renvoyé plusieurs adresses IP pour le serveur radiofrance:

Je pense que le player web du site radiofrance "jongle" avec ces adresses pour utiliser le serveur le plus disponible au lieu de prendre le dernier..

Un coup d'oeil sur les paquets échangés lors de l'utilisation du player web, montre des échanges bien plus complexes.

Le player fini par utiliser 2.21.132.169 comme serveur de stream, soit : a2-21-132-169.deploy.static.akamaitechnologies.com  ...

Install messon and ninja tools:

sudo apt-get install python3 python3-pip ninja-build
sudo pip3 install meson 

Stop mpd service:

sudo service mpd stop 

Compile mpd:

meson . output/release --buildtype=debugoptimized -Db_ndebug=true
meson configure output/release
ninja -C output/release
sudo ninja -C output/release install  

• mpd is in ./output/release
• service files are ./output/release/systemd
• use the mpdconf.example in ./doc for configuration

Workarrounds and errors:

mpd binary is located in /usr/local/bin and this mpd binary try to open mpd.conf located in /usr/local/etc NOT in usual folder /etc

So, you have to link these file and folder:

sudo mv /usr/bin/mpd /usr/bin/mpd_old
sudo ln -s /usr/local/bin/mpd /usr/bin/mpd

Check if folder /usr/local/etc already exists:

ls /usr/local

If an etc folder exists, rename it to etc_bak

sudo mv /usr/local/etc /usr/local/etc_old

Link etc folder:

sudo ln -s /etc /usr/local

move old etc files to linked folder:

sudo mv /usr/local/etc_old/* /usr/local/etc

Repairing Domoticz database...

Some error appearing in domoticz log concerning VACUUM:

2020-01-12 15:00:01.363 Error: SQL Query("VACUUM") : database disk image is malformed

First, stop domoticz:

$ sudo service domoticz.sh stop

Backup the database:

$ cp ./domoticz/domoticz.db ./domoticz/domoticz.db.bak

Method 1

$ sqlite3 ./domoticz/domoticz.db

sqlite> .output domo.sql 

sqlite> .dump

sqlite> .quit

Download domo.sql to your Windows PC,

Try to import domo.sql in Sqlite Browser ( https://sqlitebrowser.org/ ) ,

Note error messages if exists and cleanup manualy ( notepad++ ) domo.sql (duplicate inserts, etc...) until importation success.

When sql is successfully imported, save to "domoticz.db"

Upload to domoticz machine, 

$ rm ./domoticz/domoticz.db

$ cp ./domoticz.db ./domoticz/domoticz.db

$ sudo service domoticz.sh start

If no success then :

$ rm ./domoticz/domoticz.db

$ cp ./domoticz/domoticz.db.bak ./domoticz/domoticz.db

Method 2 (not worked for me)

Open database with sqlite3:

$ sqlite3 ./domoticz/domoticz.db

Check integrity:

sqlite> PRAGMA integrity_check;

*** in database main ***

On tree page 138 cell 50: Rowid 2287 out of order

row 252 missing from index ds_hduts_idx

wrong # of entries in index ds_hduts_idx

...

First reindex DeviceStatus:

sqlite> reindex ds_hduts_idx;

Check integrity again:

sqlite> PRAGMA integrity_check;

*** in database main ***

On tree page 138 cell 50: Rowid 2287 out of order

... Error: database disk image is malformed

Build a clean copy of database:

sqlite> .clone domoticz-clone.sqlite

sqlite> PRAGMA user_version;

0  <----- TAKE NOTE OF THIS VALUE it may be different for you

sqlite> .exit

Open the database copy and correct:

$ sqlite3 domoticz-clone.sqlite

sqlite> PRAGMA integrity_check;

ok

sqlite> PRAGMA user_version = 0;  -- use the number you got from PRAGMA user_version; above

sqlite> PRAGMA journal_mode = truncate;

truncate

sqlite> PRAGMA page_size = 32768;

sqlite> VACUUM;

sqlite> PRAGMA journal_mode = wal;

wal

sqlite> .exit

Copy new cleaned database on domoticz database:

$ mv domoticz-clone.sqlite ./domoticz/domoticz.db

Finally start domoticz service:

$ sudo service domoticz.sh start

You can now check domoticz log with web ui...
