Installation en mode ferme
4 février 2011, parLe mode ferme permet d’héberger plusieurs sites de type MediaSPIP en n’installant qu’une seule fois son noyau fonctionnel.
C’est la méthode que nous utilisons sur cette même plateforme.
L’utilisation en mode ferme nécessite de connaïtre un peu le mécanisme de SPIP contrairement à la version standalone qui ne nécessite pas réellement de connaissances spécifique puisque l’espace privé habituel de SPIP n’est plus utilisé.
Dans un premier temps, vous devez avoir installé les mêmes fichiers que l’installation (...)

apply ffmpeg to many files
30 juillet 2015, par puchuI have written simple script :
#!/bin/bash
find . -name "*.m4a" | while read filename;
do
new_filename=$(echo "$filename" | sed "s/^\(.*\)m4a$/\1flac/g");
if [ ! -f "$new_filename" ]
then
#ffmpeg -i "$filename" -acodec flac "$new_filename" > /dev/null 2>&1;
#wait $!;
echo "$filename";
echo "$new_filename";
fi
doneit outputs correct result :
./Equilibrium, ALAC [GER] viking.folk/2003 - Demo 2003, ALAC/04 - Met.m4a
./Equilibrium, ALAC [GER] viking.folk/2003 - Demo 2003, ALAC/04 - Met.flac
./Equilibrium, ALAC [GER] viking.folk/2003 - Demo 2003, ALAC/02 - Nach Dem Winter.m4a
./Equilibrium, ALAC [GER] viking.folk/2003 - Demo 2003, ALAC/02 - Nach Dem Winter.flacif uncomment ffmpeg and wait :
./Equilibrium, ALAC [GER] viking.folk/2003 - Demo 2003, ALAC/04 - Met.m4a
./Equilibrium, ALAC [GER] viking.folk/2003 - Demo 2003, ALAC/04 - Met.flac
uilibrium, ALAC [GER] viking.folk/2003 - Demo 2003, ALAC/02 - Nach Dem Winter.m4a
uilibrium, ALAC [GER] viking.folk/2003 - Demo 2003, ALAC/02 - Nach Dem Winter.flacAnd no flacs has been done !
PS
#!/bin/bash
find . -name "*.m4a" | while read filename;
do
new_filename=$(echo "$filename" | sed "s/^\(.*\)m4a$/\1flac/g");
if [ ! -f "$new_filename" ]
then
ffmpeg -i "$filename" -acodec flac "$new_filename";
echo "$filename";
echo "$new_filename";
fi
sleep 5;
done1) encode start but suddenly stop with no error messages
2) encode couldn’t start because of "uilibrium" instead of "./Equilibrium"

How do I accelerate fisheye to hequirect conversion with cuda ? [closed]
10 mai 2022, par ZurechtweiserThis is my command


ffmpeg -y -i in.mp4 -vf v360=input=sg:ih_fov=118.2:iv_fov=69.5:output=hequirect:w=2924:h=2924 -b:v 102400k -bufsize 5000k -c:a copy out.mp4



I tried


ffmpeg -y -hwaccel cuda -hwaccel_output_format cuda -i in.mp4 -vf v360=input=sg:ih_fov=118.2:iv_fov=69.5:output=hequirect:w=2924:h=2924 -c:v h264_nvenc -preset slow -b:v 102400k -bufsize 5000k -c:a copy out.mp4



But this resulted in


Impossible to convert between the formats supported by the filter 'graph 0 input from stream 0:0' and the filter 'auto_scale_0'
Error reinitializing filters!
Failed to inject frame into filter network: Function not implemented
Error while processing the decoded data for stream #0:0

. But in my case I have white space of video directory (you can see full path inString commandStr
onPreExecute()
method ofasynctask
) path then it is not working at all. I have also seen same question like this and some more but not get any idea how to resolved it properly. Below is my code of MainActivity.classpublic class MainActivity extends AppCompatActivity implements View.OnClickListener{
