• implement A/V streaming from PC to Android w. low latency [closed]

  11 août 2021, par kekk0

  I would like to code server/client applications to stream PC desktop audio/video to android box device. It would be limited to wired LAN connection, no internet, no wifi ; Aims are good image quality and lowest latency. I was reading about setting up an FFmpeg server on pc to hls/m3u8 and coding a simple exoplayer-based client on android device, but it seems the latency might be high (seconds). Could you suggest me some good alternative solutions ?

  


• 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]"

  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.

  


• How to compress video uploads in a WordPress website hosted on WP-Engine without FFmpeg ?

  27 février 2023, par Golipz

  I am building a WordPress website on WP-Engine and must allow users to upload videos up to 50 Mb. However, I noticed that WP-Engine presumably does not allow the installation of FFmpeg for video compression. What are the alternative methods or tools available to compress videos uploaded by clients on my website without FFmpeg ? Is there any WordPress plugin or other solutions available ? Any suggestions or insights would be greatly appreciated. I really appreciate any help you can provide.
