• AFTER PHP-FFMpeg not converting (error with ffmpeg)

  15 juin 2018, par Magurean Dan Sergiu

  I have installed ffmpeg server side with all the dependencies, updated it. And then installed PHP-FFMpeg with Composer. Tested that ffmpeg is instaled with a ssh conexion.

  root@host [/opt/ffmpeg]# ffmpeg

  Use -h to get full help or, even better, run 'man ffmpeg'

  But when I try to convert a video file with a php script it throws me a very long error.
  PHP Code :

  <?PHP
  
  include($_SERVER['DOCUMENT_ROOT']."/vendors/install/vendor/autoload.php");
  
  $ffmpeg = FFMpeg\FFMpeg::create();
  
  $video = $ffmpeg->open($_SERVER['DOCUMENT_ROOT'].'/resources/uploads/96048/ffd3c5e349fa5745159deef163b5c253.wmv');
  
  $video
  
         ->filters()
  
         ->synchronize();
  
  $format = new FFMpeg\Format\Video\X264();
  
  $format->on('progress', function ($video, $format, $percentage) {
  
      echo "$percentage % transcoded";});
  
  $video
  
        ->save($format,$_SERVER['DOCUMENT_ROOT'].'/resources/uploads/96048/ffd3c5e349fa5745159deef163b5c253.mp4');
  
  ?>

  Error displayed :

  Unknown encoder 'libx264'

  My question is what to do next ? I have wasted 3 days to make this work and this is the furthest I have come. How can I test if libx264 is installed corectly ? And if it is not installed corectly how cand I reinstal or make it work ?

  After a few modifications

  I have used an already installed ffmpeg, and removed a few commands (that were by default the same) and this time I used only the command line.

• ffmpeg use gpu to encode mpeg4 to ts/m3u8 [closed]

  14 novembre 2024, par danielRICADO

  using ffmpeg I want to trim and transcode a mpeg4 from ts / m3u8

  


  std::string ffmpeg_command = "ffmpeg -hwaccel drm -i " + output_dir + input_file +
                         " -ss 00:00:00.00 -t 31 -c:v " + codec + " -b:v " + std::to_string(bitrate) +
                         " -vf scale=" + std::to_string(width) + "x" + std::to_string(height) +
                         " -hls_time " + std::to_string(30) + " -hls_list_size 0 -hls_segment_filename " +
                         ts_file_pattern + " -f hls " + m3u8_file;


  


  I wanted to choose between codecs based on the system, if gpu is avaiable I'd like to opt to use it, right now I just check if the codec is available

  


  bool is_h264_v4l2m2m_available() {
    std::string result = exec_command("ffmpeg -encoders 2>&1");
    return result.find("h264_v4l2m2m") != std::string::npos;
}


  


  if it is a I wanted to move that process over to the gpu, not just use libx264. Here is the error log. Studying hard on the solution but wold super apperciate any expert advice.

  


  other considerations are - runs in a docker container on a pi5, pibian on the host apline on in the container, container runs in privledged mode

• I cannot play a mp3 file on Discord's voice channel using discord.py

  1er décembre 2024, par ra1ned

  I am creating a discord bot that plays lofi for me. It does not play a song for me even though it shows a green indicator on a voice channel.

  


  Here's what I've written :

  


  if message.content == "!join":
    await message.author.voice.channel.connect()
    await message.channel.send("Successfully connected")

if message.content == "!play":
    if message.guild.voice_client is None: 
        await message.channel.send("use !join")
        return
    
    await message.channel.send("playing a song rn")
    print('*** playing a song rn')
    
    message.guild.voice_client.play(discord.FFmpegPCMAudio('lofi.mp3'))


  


  I put FFmpeg.exe and lofi.mp3 in the same directory as this script.
Also, it is strange that FFmpeg does not return any exception nor output on console although it seems to have failed to load the file. I have seen people who had the same problem, but it seems like that they get some error messages, unlike me.

  


  Here's the output on console after using !join

  


  2024-12-01 16:59:39 INFO     discord.voice_state Connecting to voice...
2024-12-01 16:59:39 INFO     discord.voice_state Starting voice handshake... (connection attempt 1)
2024-12-01 16:59:40 INFO     discord.voice_state Voice handshake complete. Endpoint found: japan8946.discord.media
2024-12-01 16:59:40 INFO     discord.voice_state Voice connection complete.


  


  after using !play, it only displays the message I wrote :

  


  *** playing a song rn


  


  Can someone help me with this ?
