• movenc : Fix conversion of the first frame for extradata-less H264/HEVC

  movenc : Fix conversion of the first frame for extradata-less H264/HEVC
  Move the copying of the frame to vos_data further up in the function,
  
  so that when writing the actual frame data for the first frame, it's
  
  clear that the stream really is in annex b format, for the cases where
  
  we create extradata from the first frame.
  Alternatively - we could invert the checks for bitstream format. If
  
  extradata is missing, we can't pretend that the bitstream is in
  
  mp4 form, because we can't even know the NAL unit length prefix size
  
  in that case.
  Also avoid creating extradata for AVC intra. If the track tag is
  
  an AVC intra tag, don't copy the frame into vos_data - this matches
  
  other existing cases of how vos_data and TAG_IS_AVCI interact in
  
  other places.

• Invalid data found when processing input for Streaming Discord Bot

  4 mai 2022, par DimKewl

  I tried a variety of streaming links that were working in the past for the same code.
After refactoring and working on all possible solutions I could find on google
I always get the following error :

  


  Invalid data found when processing input

  


  My code snippet :

  


   FFMPEG_OPTIONS = {
    "before_options": "-reconnect 1 -reconnect_streamed 1 -reconnect_delay_max 5",
    "options": "-vn -sn -dn"
}
@commands.command()
async def radio(self,ctx,url):
    await self.joinLogic(ctx)
    await self.playStreamOpus(ctx,url)

async def joinLogic(self, ctx):
    if ctx.author.voice is None:
        await ctx.send("Please join a voice channel!")
    else:
        voice_channel = ctx.author.voice.channel
        if ctx.voice_client is None:
            await voice_channel.connect()

async def playStreamOpus(self, ctx, url):
    source = await discord.FFmpegOpusAudio.from_probe(url, **self.FFMPEG_OPTIONS)
    ctx.voice_client.play(source)


  


  What have I already tried :

  


  

  • Re-install all dependencies on pip.

  


  • Tried the PCM instead of Opus.

  


  • Different streaming URLs.

  


  • More options in FFMPEG_Options to explicit that I need only audio.

  


  • Made sure that my bot is joined in my channel and can reach other places in my code.

  


  


• How to install avconv for youtube-dl

  23 janvier 2016, par Hashim

  Up till now, I’ve been using youtube-dl with ffmpeg. I’ve had a few problems doing so, which I posted about in another question, but for the most part, I managed to get ffmpeg set up without a hitch. After having problems converting certain file formats with ffmpeg, I was advised in that question to try and switch to avconv to see whether ffmpeg was indeed the problem, and basically help me troubleshoot, but despite trying for the last 3 hours, I’ve been unable to even get avconv set up.

  So far, I’ve downloaded several of the releases for my Windows 7 x64 operating system from the libav website, each time copying the exact folder structure into the folder where my youtube-dl.exe is, and then making sure that location and the bin folder is in the PATH environment variable. The folder structure looks like this : C:\Program Files (x86)\youtube-dl\usr\bin, where bin contains avconv.exe and the rest of the files that it needs. Does anyone have any clue as to why this isn’t working for me ? It’s beyond me how something so critical to a program as popular as youtube-dl could be so hard and/or badly-documented to get set up.

  Thanks for any help in advance, it’s much appreciated.

  EDIT : Something peculiar that I’ve noticed. When getting rid of all traces of avconv and ffmpeg, youtube-dl throws up the usual error of needing them to convert. But when just the avconv folders are in the necessary places, youtube-dl recognises it as ffmpeg and starts processing the files as such.
