• AttributeError : 'FFmpegAudio' object has no attribute '_process' while trying to play audio from URL

  13 août 2022, par jmcamacho7

  I can't find any solution online and I don't know what's wrong.

  


  My code is : (Not pasting the URL getting since that works fine)

  


  from urllib import parse, request
import re
import pafy
from discord import FFmpegPCMAudio, PCMVolumeTransformer

FFMPEG_OPTIONS = {
    'before_options': '-reconnect 1 -reconnect_streamed 1 -reconnect_delay_max 5', 'options': '-vn'
}

@bot.command(pass_context=True)
async def play(ctx, * , search):
  query_string = parse.urlencode({'search_query': search})
  html_content = request.urlopen('http://www.youtube.com/results?' + query_string)
  search_results=re.findall('watch\?v=(.{11})',html_content.read().decode('utf-8'))
  print(search_results[0])
  
  if(ctx.author.voice):
    channel = ctx.message.author.voice.channel
    await ctx.send("https://www.youtube.com/watch?v="+search_results[0])  
    url = "https://www.youtube.com/watch?v="+search_results[0]
    conn = await channel.connect()
    conn.play(discord.FFmpegAudio(url, **FFMPEG_OPTIONS))
  else:
    await ctx.send("Necesitas estar en un canal de audio para usar este comando")


  


  It just gives me this error everytime I try it :

  


  Traceback (most recent call last):
  File "/home/runner/HakuBot/venv/lib/python3.8/site-packages/discord/player.py", line 103, in __del__
    self.cleanup()

    proc = self._process
AttributeError: 'FFmpegAudio' object has no attribute '_process'


  


  Anyway to solve this ?

  I have this code, and i would like to remove audio from tracks 5 and 6. I had tried everything but is not working, I can mute the audio tracks but on edition program i can see the waves, can you help me ?

  


  if (conv.format === 'mxf') {
        // Add 8 audio tracks
        ffmpeg(inputFile)
            .audioCodec('pcm_s16le') // Codec de áudio para MXF
            .outputOptions([
                '-c:v mpeg2video', // Codec de vídeo para MXF
                '-q:v 2', // Qa  vídeo
                '-map 0:v:0', 
                '-map 0:a:0', 
                '-map 0:a:0',

            ])
            .save(outputFile)
            .on('start', commandLine => console.log(`FFmpeg comando iniciado: ${commandLine}`))
            .on('progress', progress => console.log(`Progresso: ${progress.percent}%`))
            .on('end', () => console.log(`Conversão concluída: ${outputFile}`))
            .on('error', err => console.error(`Erro na conversão de ${inputFile} para ${outputFile}: ${err.message}`));
    } else {
        // Outras conversões
        ffmpeg(inputFile)
            .outputOptions(conv.options)
            .save(outputFile)
            .on('start', commandLine => console.log(`FFmpeg comando iniciado: ${commandLine}`))
            .on('progress', progress => console.log(`Progresso: ${progress.percent}%`))
            .on('end', () => console.log(`Conversão concluída: ${outputFile}`))
            .on('error', err => console.error(`Erro na conversão de ${inputFile} para ${outputFile}: ${err.message}`));
    }


  


  I tried to use ffmpeg comands to remove audio from track.

  


• RTSP to HLS conversion with error on some devices

  2 septembre 2024, par Wallace Ketler

  I'm trying to convert, on a node server, RTSP IP camera devices to HLS to run livestreams on the web. The following code works well for some RTSP devices, but for others I encounter problems.

  


     function startLive(rtspUrl, outputDir, id_local, id_camera) {
        return new Promise((resolve, reject) => {
            const processKey = `${id_local}_${id_camera}`;
            if (ffmpegProcesses[processKey]) {
                return reject(new Error('Conversão já está em andamento para esta câmera'));
            }
        
            const process = ffmpeg(rtspUrl)
                .inputOptions([
                    '-rtsp_transport', 'tcp',
                    '-fflags', 'nobuffer',
                    '-max_delay', '1000000',
                    '-analyzeduration', '1000000',
                    '-probesize', '1000000',
                    '-flush_packets', '1',
                    '-avioflags', 'direct'
                ])
                .outputOptions([
                    '-c:v', 'libx264',
                    '-preset', 'ultrafast',
                    '-tune', 'zerolatency',
                    '-c:a', 'aac',
                    '-hls_time', '10',
                    '-hls_flags', 'delete_segments',
                    '-hls_list_size', '5',
                    '-hls_wrap', '5',
                    '-strict', '-2'
                ])
                .output(path.join(outputDir, 'stream.m3u8'))
                .on('start', (commandLine) => {
                    console.log('Spawned FFmpeg with command: ' + commandLine);
                })
                .on('stderr', (stderrLine) => {
                    console.log('FFmpeg stderr: ' + stderrLine);
                })
                .on('end', () => {
                    console.log('Conversão concluída');
                    delete ffmpegProcesses[processKey]; 
                    resolve();
                })
                .on('error', (err, stdout, stderr) => {
                    console.error('Erro na conversão', err);
                    console.error('FFmpeg stdout:', stdout);
                    console.error('FFmpeg stderr:', stderr);
                    delete ffmpegProcesses[processKey]; 
                    reject(err);
                })
                .run();
    
            ffmpegProcesses[processKey] = process; 
        });
    }


  


  When the conversion succeeds, it continues indefinitely with the logs :

  And with the segments saved in the folder configured as output. But for certain devices, after creating the stream.m3u8 file and saving the first segment, the conversion is considered finished and falls into .on('end') . The error log is as follows :

  


  FFmpeg stderr: frame=    0 fps=0.0 q=0.0 size=N/A time=00:00:01.12 bitrate=N/A speed=2.08x    
FFmpeg stderr: [hls @ 0x55e00dfc4380] Opening 'my_path/stream0.ts' for writing
FFmpeg stderr: [hls @ 0x55e00dfc4380] Opening 'my_path/stream.m3u8.tmp' for writing

FFmpeg stderr: video:0kB audio:0kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: unknown
FFmpeg stderr: [aac @ 0x55e00dfff840] Qavg: 65536.000
FFmpeg stderr: 
Conversão concluída


  


  The muxing overhead: unknown only appears when the error occurs and the conversion is complete.

  


  I've already tried changing the video and audio encoders, as well as the various input and output parameters of the conversion. I also tried updating ffmpeg (it's already on the latest version, using fluent-ffmpeg, "fluent-ffmpeg": "^2.1.3",)

  


  I would like to understand why this happens on some devices and how to fix it. Thanks.
