• use BytesIO into python-ffmpeg or other

  3 mai 2022, par Tlaloc-ES

  Hello I have the following poc to develop

  


  Given two S3 paths, origin and destination, I need to download from origin apply a conversion and upload to destination.

  


  The idea is not to use a temporary local folder and use stream data ur another better option if you know.

  


  In order to do this I have the following code :

  


  import ffmpeg
import boto3
from io import BytesIO

origin = 'ah/a.mkv'
destination = 'av/a.mp4'

s3_client = boto3.client('s3')

f = BytesIO()
s3_client.download_fileobj('bucket', origin, f)

stream = ffmpeg.input(f)
stream = ffmpeg.output(stream, 'a.mp4', codec='copy')

(stream.run())


  


  The problem is that

  


  Input doesn' this library looks like that this operation is not possible.

  


  https://kkroening.github.io/ffmpeg-python/

  


  


  TypeError : expected str, bytes or os.PathLike object, not _io.BytesIO

  


  


  But when another library like

  


  https://github.com/aminyazdanpanah/python-ffmpeg-video-streaming#opening-a-resource

  


  I don't know how do the conversion too.

  


  So do you know any way of do this ?

  


  Thanks

  


• Discord audio playing issue

  24 avril 2022, par ItsNaif.

  Explanation

  


  I have this code that plays youtube video audio in voice channels.

  


  When it joins the channel I get an error that says "ffmpeg not found". I ran the terminal command "npm i ffmpeg-static" and it worked fine but after a couple of minutes I get a long error and the music stops playing.

  


  This is my code :

  


  client.on("ready", async () => {

  for (const channelId of Channels) {
    joinChannel(channelId);

    await new Promise(res => setTimeout(()=>res(2), 500))
  }
  
  function joinChannel(channelId) {
    client.channels.fetch(channelId).then(channel => {

      const VoiceConnection = joinVoiceChannel({
        channelId: channel.id,
        guildId: channel.guild.id,
        adapterCreator: channel.guild.voiceAdapterCreator
      });
      const resource = createAudioResource(ytdl("https://youtu.be/0J2gdL87fVs", {
          filter: "audioonly"
      }), {
        inlineVolume: true
      });
      resource.volume.setVolume(0.2);
      const player = createAudioPlayer()
      VoiceConnection.subscribe(player);
      player.play(resource);
      player.on("idle", () => {
        try {
          player.stop()
        }catch (e) {}
        try {
          VoiceConnection.destory()
        }catch (e) {}
        joinChannel(channelId)
      })
    }).catch(console.error)
  }
})


  


• crossorigin header in php is not working after previous php exec ffmpeg command

  17 avril 2022, par ivyyeziyang

  I am using php exec function to execute a FFMPEG command, but I am also using Javascript to send the request and they are cross origin requests, but after the exec command, while I start to send next cross origin request, it shows
Access to XMLHttpRequest at 'https://www..com:550/api/adminapi' from origin 'https://www..com:8081' has been blocked by CORS policy : No 'Access-Control-Allow-Origin' header is present on the requested resource.
which means the cross origin header is not working in the next cross origin request after exec command,
below is the code :

  


  if (isset($_POST['crossorigin'])) {
$crossoriginallow = array();
$crossoriginallow = [
'https://www.***.com:8080', 
'https://www.***.com:8081', 
'https://www.***.com:8082'];
for ($i = 0; $i < sizeof($crossoriginallow); $i++) {
if ($crossoriginallow[$i] == $_POST['crossorigin']) {
  $crossorigin = $_POST['crossorigin'];
  break;
  }
}
header("Access-Control-Allow-Origin:$crossorigin");
header("Access-Control-Allow-Methods:GET, POST, OPTIONS, DELETE");
header("Access-Control-Allow-Headers:DNT,X-Mx-ReqToken,Keep- 
Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache- 
Control,Content-Type, Accept-Language, Origin, Accept-Encoding");
}

exec("ffmpeg -i " . $infilepath . " -c:v mpeg4 -preset veryslow - 
 c:a mp3 -q 0 " . $outfilepath /* . " 2>&1" *//* , $out */);

 $infilepathsep = explode('/', $infilepath);
 $folderpath = '';
 for ($i = 0; $i < sizeof($infilepathsep) - 1; $i++) {
 $folderpath = $folderpath . $infilepathsep[$i];
 $folderpath = $folderpath . '/';
}

 $opendirhandle = opendir($folderpath);
 closedir($opendirhandle);
 $openfilehandle = fopen($infilepath, 'r');
 fclose($openfilehandle);
 unlink(iconv("utf-8", "gbk", $infilepath));
 $result['data'] = $outfilepath;
 $result['msg'] = 'success';
 $jsonresult = json_encode($result);
 echo $jsonresult;
 ob_get_contents();
 ob_end_flush();


  


  I does not encounter this problem before using the same code,but after I reinstall the computer it happens, May I please ask the reason if you know the problem ? Thank you very much for your help !
