  I get this error to play video in hls player :

  


  Cannot play media. No decoders for requested formats : application/vnd.apple.mpegurl

  I am using Windows Server 2019, on which I also installed ffmpeg.

• Suggest an Android FFMPEG Media Player App Supporting SRT Protocol for Video Streaming [closed]

  12 décembre 2023, par ChanduGudimetla

  I am currently in search of an Android application that can serve as a receiver or media player utilizing FFMPEG over the SRT (Secure Reliable Transport) protocol. My primary goal is to receive a video stream from one device (Device A) and mirror the screen onto another device (Device B).

  


  Source Application : I am using StreamPack APK on Device A, which handles the encoding of data effectively. Requirement : I need a receiver application for Device B that can decode this stream.

  


  The key requirements are : It should leverage FFMPEG for decoding. It must support the SRT protocol to ensure secure and reliable video streaming.

  


• check media resolution, if resolution is big ffmpeg it, if output is smaller than original delete the original else delete the output

  13 avril 2015, par The Wolf

  I have my storage VPS filled with videos, and hoping I can free up some space, their resolution is pretty big so I decided to re encode them with ffmpeg to a smaller resolution, I am doing every thing manually, first I check using mediainfo test5.mkv the resolution

  ...
  
  Width                                    : 1 280 pixels
  
  ...

  if the width is greater than 720 pixels I issue the following command :

  ffmpeg -i 'test5.mkv' -vf scale=720:-2 -acodec copy -vcodec libx264 -scodec copy -threads 12 -crf 28 -x264-params keyint=240:min-keyint=20 -preset:v slow '[Encoded] test5.mkv'

  then after that I delete the original video if the output has smaller size than the original

  I am hoping there is a script that can automate this, like I will run on a directory then, it will look for all .mkv to subdirectories recursively to perform this checks and actions. How to do this ?

  Also, I am worried that it could fail if I reach automation, since there are special characters in the video’s name of some like single quotes, double quotes, or `, so I will it can be escaped properly.

  Thanks !

  After some google I ended up with the following snippet, I am worried if this is enough, but I’m afraid to run it since I am not sure if it would damage my unix

  #!/bin/sh
  
  
  
  for file in *.{mkv}; do
  
  target="[720p]-${file%.*}.mkv"
  
  [[ -f "$target" ]] && { echo "skipping $file - $target exists" ; continue; }
  
  
  
  
  
  eval $(ffprobe -v error -of flat=s=_ -select_streams v:0 -show_entries stream=height,width "$file")
  
  size=${streams_stream_0_width}x${streams_stream_0_height}
  
  if [ "$streams_stream_0_width" -ge 720 ]; then
  
  echo ffmpeg -i "$file" -vf scale=720:-2 -acodec copy -vcodec libx264 -scodec copy -threads 12 -crf 28 -x264-params keyint=240:min-keyint=20 -preset:v slow "$target"
  
  
  
  fi
  
  done

  can somebody please tell me if my snippet should work ?

  UPDATE

  as it turns out if [ "$streams_stream_0_width" -ge 720 ]; then fails because the width is not integer ? line 10: [: : integer expression expected I am not sure why it is not integer, how can I make it integer ?
