• ffmpeg random mp3 audio play

  24 août 2021, par Arky

  I stream images from an IP camera to an external player and play back mp3 files as background music in a loop. In order to keep the playback continuity, I combined several mp3 songs together. Each time the external player is started, the background music starts from the same track (which was saved first as a result of joining mp3 files). When I start the player, I would like to run a random mp3 file as background music and play the whole list in random order and additionally in a loop.
Here is my current camera streaming code + logo position + mp3 playback

  


   ffmpeg -stimeout 5000000 -rtsp_transport tcp \
 -i "rtsp://IP:PORT/Streaming/Channels/101/" \
 -i /root/logo_streaming.png -filter_complex "overlay=x=main_w-overlay_w-30:y=30" -stream_loop -1 \
 -i /root/mix_57m37s.mp3 \
 -vcodec libx264 -preset veryfast -vprofile baseline -x264opts keyint=40 -b:v 4096k -bufsize 1024k \

• How do I make my discord.py bot play mp3 in voice channel ?

  17 décembre 2020, par ropke

  I'm a beginner in Python and I have recently started making a discord bot for some friends and I. The idea is to type !startq and have the bot join the channel, play an mp3 file that is locally stored in the same folder that the bot.py is in also.

  



  import discord, chalk
from discord.ext import commands
import time
import asyncio

bot = commands.Bot(command_prefix = "!")

@bot.event
async def on_ready():
    print("Bot is ready!")

@bot.command()
async def q5(ctx):
    await ctx.send("@here QUEUE STARTING IN 5 MINUTES")

@bot.command()
async def q3(ctx):
    await ctx.send("@here QUEUE STARTING IN 3 MINUTES")

@bot.command()
async def q1(ctx):
    await ctx.send("@here QUEUE STARTING IN 1 MINUTES")

@bot.command()
async def ping(ctx):
    ping_ = bot.latency
    ping =  round(ping_ * 1000)
    await ctx.send(f"my ping is {ping}ms")

@bot.command()
async def startq(ctx):
    voicechannel = discord.utils.get(ctx.guild.channels, name='queue')
    vc = await voicechannel.connect()
    vc.play(discord.FFmpegPCMAudio("countdown.mp3"), after=lambda e: print('done', e))
    bot.run('TOKEN')


  



  So far my bot joins the channel fine, but it doesn't actually play the mp3. I've asked countless people in the "Unofficial Discord API Discord" and a few other programming Discords, but I haven't gotten an answer yet.

  


• Is it possible to play two videos as one like this ? [on hold]

  25 février 2015, par Marko

  Is it possible to show/play video online that’s made of two or more video files ? Here’s explanation.

  My site is hosted on Linux/Appache/PHP server. I have video files in FLV/F4V format.

  What I want is to have online video player that plays video composed of multiple video files concatenated together in real-time, i.e. when user clicks to see a video.

  Resulting video looks like one video, with no visual clues, lags or any delay between videos parts. Basically what is done is some form of on-the-fly editing or pre-editing, and user sees the result.

  Is this possible anyhow with flash, actionscript, ffmpeg, php, html or some other online technology ? I don’t need explanation how it’s possible, but just a nod that it’s possible and some links to further investigate.
