• 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

  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.

  


• ffmpeg converting mov to mp4

  16 mai 2019, par alienbuild

  Trying to convert .mov to .mp4. Tried various suggestion codes on stackoverflow but nothing seems to be working.

  `...muxer does not support non seekable output [48] => Could not write header for output file #0 (incorrect codec parameters ?): Invalid argument [49] => Error initializing output stream 0:0 -- [50] => Conversion failed! ) 1`

  I’ve tried various codec properties such as ac3, aac, libvo_aacenc

  exec('
  
  /usr/local/bin/ffmpeg -y -i https://***.***.com/assets/regions/region-1/input.mov' . 
  
  ' -c:a ac3 ' 
  
  . 'https://***.***.com/assets/regions/region-1/output.mp4' 
  
  . ' 2>&1', $out, $res);
  
  
  
  $modx->log(modX::LOG_LEVEL_ERROR, print_r($out));
  
  $modx->log(modX::LOG_LEVEL_ERROR, $res);
  
  
  
  return true;

• FFMpeg : how to blur two fixed regions at the bottom of the video file ?

  24 décembre 2022, par bully44

  I'm trying to blur to rectangular regions at the bottom of the video. Only short region around center should stay as it is, and 140 pixels regions on both sides should be blurred.
The left region is ok, but just cannot set correctly the right one. For visual reason, I'm displaying it higher, but I just cannot get x coordinate and size in correct position.

  


  ffmpeg -i Test1.mp4 -filter_complex  \
"[0:v]crop=iw/2-40:140:0:ih-140,avgblur=10[b0]; \
 [0:v]crop=iw/2-50:140:iw/2+200:ih-140,avgblur=5[b1]; \
 [0:v][b0]overlay=0:H-h[ovr0]; \
 [ovr0][b1]overlay=W/2+100:H-h-500" \
 -c:a copy -movflags +faststart Test_blur.mp4


  


  As FFMpeg newbie, I must be doing something obviously wrong.
Thanks in advance,
regards.
