• trying to play audio from youtube with ffmpeg on discord.py rewrite

  13 septembre 2021, par Bobby Cook

  im trying to use a discord bot that plays music, but im getting errors when i run this code and python crashes, and i cant quite figure out whats wrong, except for that its around the @client.command(pass_context=True) async def play(self, ctx, *, url): print(url) server = ctx.message.guild voice_channel = server.voice_client
block. the i apologize for wasting all your time, im really bad at this, and i didnt even write most of this.

  


  import random
import youtube_dl
from discord.ext import commands
from discord.ext import tasks

client = commands.Bot(command_prefix = 'f!')

@client.command()
async def join(ctx):
    channel = ctx.message.author.voice.channel
    await channel.connect()

@client.command()
async def leave(ctx):
    await ctx.voice_client.disconnect()

youtube_dl.utils.bug_reports_message = lambda: ''


ytdl_format_options = {
    'format': 'bestaudio/best',

ytdl = youtube_dl.YoutubeDL(ytdl_format_options)

        super().__init__(source, volume)

        self.data = data

        filename = data['url'] if stream else ytdl.prepare_filename(data)

  I use ffmpeg to convert gif to mp4 on Android. And part of configuration is :

   --disable-encoders \
  
   --disable-decoders \
  
   --enable-small \
  
   --enable-encoder=libx264 \
  
   --enable-encoder=flv \
  
   --enable-encoder=opus \
  
   --enable-encoder=gif \
  
   --enable-decoder=h264 \
  
   --enable-decoder=flv \
  
   --enable-decoder=opus \
  
   --enable-decoder=gif \

  However I can not play the output mp4 on Android. But pc can play it.

  ffmpeg -i output.mp4

  Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'output.mp4':
  
    Metadata:
  
      major_brand     : isom
  
      minor_version   : 512
  
      compatible_brands: isomiso2avc1mp41
  
      encoder         : Lavf58.12.100
  
    Duration: 00:00:09.73, start: 0.000000, bitrate: 330 kb/s
  
      Stream #0:0(und): Video: h264 (High 4:4:4 Predictive) (avc1 / 0x31637661), yuv444p, 280x174, 328 kb/s, 11 fps, 11 tbr, 11264 tbn, 22 tbc (default)

  Is there anything wrong ?

• gstreamer vaapih264enc generated ts segment dont play on AVPlayer

  21 juin 2022, par Guru Govindan

  I have a pipeline that transcodes an rtsp stream into hls segments. The manifest is playable in browsers(with hlsjs) and ffplay and VLC. However when I play the stream or individual ts segments in Quicktime player or my IOS App that uses avplayer, it doesnt work.

  


  This seems to be an issue only with vaapih264enc. When I try the same with software encode like x264enc it works fine.

  


  The following is a simple pipeline where this is reproducible.

  


  GST_DEBUG=3 gst-launch-1.0 rtspsrc location='rtsp://user:pass@10.10.10.12:554/' name=rtpsrc0 \
 rtpsrc0. ! rtph264depay ! queue ! decodebin ! vaapih264enc ! mpegtsmux name=mux ! filesink location=mymux.ts \
 rtpsrc0. ! decodebin ! queue ! fdkaacenc ! mux.


  


  when I run the following command to copy the encoded stream as is from the generated ts segment it works

  


  ffmpeg -i mymux.ts -c copy mymux_ffmpeg.ts


  


  Is the ffmpeg adding some additional header information that the quicktime player is happy with ?

  


  I appreciate any help with this.
