• Anomalie #2381 : Corriger le niveau d’intertitre

  9 juin 2018, par b b

  Il y a des H2 dans la dist, qui introduisent des listes d’articles, de résultats, ou des blocs (forum), je pense qu’ils peuvent rester comme ça.

  Si le bloc de forum sous le texte de l’article reste en h2, il va se retrouver "au même niveau" qu’un intertitre en h2 donc, c’est pas top non ?

• mpv player with SFTP does not work in bash script [closed]

  19 mars 2024, par Pickles888

  I am making a bash script to make it easier to stream from my media server at home.

  


  In the bash script, it asks whether you want to list or search, and then uses mpv to stream the file. For some reason it says the file does not exist. When I try this in the terminal it works, but running the script gives this error :

  


  [ffmpeg] libssh: Error opening sftp file: SFTP server: No such file
Failed to open sftp://[username:password]@[ip.of.server]/[directory/to/file]


  


  My script :

  


  #!/bin/bash

pass="[password]"

if [ $(nmcli | grep -c [home-network]) -gt 0 ]; then
    ip="[private.ip]"
else
    ip="[public.ip]"
fi

mfolder="[/directory/of/file]"

function select_option {

    # little helpers for terminal print control and key input
    ESC=$( printf "\033")
    cursor_blink_on()  { printf "$ESC[?25h"; }
    cursor_blink_off() { printf "$ESC[?25l"; }
    cursor_to()        { printf "$ESC[$1;${2:-1}H"; }
    print_option()     { printf "   $1 "; }
    print_selected()   { printf "  $ESC[7m $1 $ESC[27m"; }

                         if [[ $key = $ESC[A ]]; then echo up;    fi
                         if [[ $key = $ESC[B ]]; then echo down;  fi
                         if [[ $key = ""     ]]; then echo enter; fi; }

    # initially print empty new lines (scroll down if at bottom of screen)
    for opt; do printf "\n"; done

    # determine current screen position for overwriting the options
    local lastrow=`get_cursor_row`
    local startrow=$(($lastrow - $#))

    # ensure cursor and input echoing back on upon a ctrl+c during read -s
    trap "cursor_blink_on; stty echo; printf '\n'; exit" 2
    cursor_blink_off

        esac
    done

    # cursor position back to normal
    cursor_to $lastrow

    cursor_blink_on

    return $selected
}

stream() {

    clear
    sshpass -p "$pass" ssh [username]@$ip ls "$mfolder"
    search
}

cmd() {
    read -p "List or Search 
(S/l)> " cmd
    printf '\n'
    
    if [[ "$cmd" == "S" || "$cmd" == "s" ]]; then
        search
    elif [[ "$cmd" == "L" || "$cmd" == "l" ]]; then
        list
    else
        search
    fi
}

main() {
    cmd
}

main


  


  Anything put in brackets is to not share my personal info (except for arrays, if statements etc)

  


  Also this seems to have only changed while I was making the script. In the beginning, it was working great, but at one point it randomly stopped working.

  


  I have a feeling its some kind of quote mess up or something stupid like that. I have tried to edit it and fix it to the best of my abilities but nothing I did fixed it.

  


  I also think it could have to do with it being run in the bash environment as I normally use zsh. However I tested it in my shell by running /bin/bash and executing the command and it worked.

  


  Also the option chooser was not made by me.

  


• C program cannot find function which included in header file

  17 juin 2013, par Juneyoung Oh

  I made program like this.

    1 #include 
  
    2 #include 
  
    3 #include 
  
    4 #include "libavformat/avformat.h"
  
    5 
  
    6 int main (int argc, char* argv[]){
  
    7         av_register_all();
  
    8         return 0;
  
    9 }

  My header file located in

  root@ubuntu:/home/juneyoungoh/getDuration# find / -name "avformat.h"
  
  /root/ffmpeg/libavformat/avformat.h
  
  /usr/local/include/libavformat/avformat.h

  then I run with gcc getDuration.c , but I show message like below.

  root@ubuntu:/home/juneyoungoh/getDuration# gcc getDuration.c 
  
  /tmp/ccwjonqH.o: In function `main':
  
  getDuration.c:(.text+0x10): undefined reference to `av_register_all'
  
  collect2: ld returned 1 exit status

  Frankly, I do not have any idea what makes this.

  Thanks for your answers.

  ========================== edited #1 ===========================

  when I "ls /usr/local/lib", I get this.

  root@ubuntu:/home/juneyoungoh/getDuration# ls /usr/local/lib/
  
  libavcodec.a   libavutil.a    libopus.la       libvpx.a   python2.7
  
  libavdevice.a  libfdk-aac.a   libpostproc.a    libx264.a
  
  libavfilter.a  libfdk-aac.la  libswresample.a  libyasm.a
  
  libavformat.a  libopus.a      libswscale.a     pkgconfig

  you can see libavformat.a in the very first of the last line.

  so if I command like what you suggest, I get below.

  /root/ffmpeg/libavformat/vqf.c:244: undefined reference to `av_free_packet'

  /root/ffmpeg/libavformat/wavenc.c:181: undefined reference to `av_log'

  It is too long, so I just post little part of that.

  I think all link of libavformat has been broken, But I do not know

  what can I do to fix that link.

  I have installed that their official link said.
