FFmpeg avio_open_dir returns -40 on Windows, even when directory exists
28 janvier, par グルグルI'm use ffmpeg7.1 on windows 10. And libavformat's version is 61.
I use a absolute path of a directory on
avio_open_dirbut it's failed, and return -40.
I useav_err2strgotFunction not implemented.
What problem it is ?

extern "C"
{
#include <libavformat></libavformat>avformat.h>
}

int main()
{
 av_log_set_level(AV_LOG_DEBUG);

 auto dir = "D:\\music";
 AVIODirContext* dirCtx;
 auto ret = avio_open_dir(&dirCtx, dir, nullptr);
 if (ret < 0)
 {
 av_log(nullptr, AV_LOG_ERROR, "Can't open %s: %s\n", dir, av_err2str(ret));
 exit(EXIT_FAILURE);
 }
}


output


Can't open D:\music: Function not implemented


It's not the path incorrect problem. I used
std::filesystem::exists("D:\\music") && std::filesystem::is_directory("D:\\music")to verify that the path is correct.

Youtube Dlp returns with error code of 400 [closed]
10 mars 2024, par nikita goncharovI have a python discord bot that can play music and uses discord.py https://discordpy.readthedocs.io/en/stable/. To play get the music I use yt_dlp or youtube_dl. But when requesting a video it returns with a 400 error code.


This is the error with yt_dlp :


WARNING: [youtube] YouTube said: ERROR - Precondition check failed.

WARNING: [youtube] HTTP Error 400: Bad Request. Retrying (1/3)...

WARNING: [youtube] YouTube said: ERROR - Precondition check failed.

WARNING: [youtube] HTTP Error 400: Bad Request. Retrying (2/3)...

WARNING: [youtube] YouTube said: ERROR - Precondition check failed.

WARNING: [youtube] HTTP Error 400: Bad Request. Retrying (3/3)...

WARNING: [youtube] YouTube said: ERROR - Precondition check failed.

WARNING: [youtube] Unable to download API page: HTTP Error 400: Bad Request (caused by <httperror>)</httperror>

I will leave some of the code that I use for my bot... The youtube setup settings :


import youtube_dl


or


import yt_dlp as youtube_dl


youtube_dl.utils.bug_reports_message = lambda: ''


ytdl_format_options = {
 'format': 'bestaudio/best',
 'outtmpl': '%(extractor)s-%(id)s-%(title)s.%(ext)s',
 'restrictfilenames': True,
 'noplaylist': True,
 'nocheckcertificate': True,
 'ignoreerrors': False,
 'logtostderr': False,
 'quiet': True,
 'no_warnings': True,
 'default_search': 'auto',
 'source_address': '0.0.0.0', # bind to ipv4 since ipv6 addresses cause issues sometimes
}

ffmpeg_options = {
 'options': '-vn',
}

ytdl = youtube_dl.YoutubeDL(ytdl_format_options)


class YTDLSource(discord.PCMVolumeTransformer):
 def __init__(self, source, *, data, volume=0.5):
 super().__init__(source, volume)

 self.data = data

 self.title = data.get('title')
 self.url = data.get('url')
 self.duration = data.get('duration')
 self.image = data.get("thumbnails")[0]["url"]
 @classmethod
 async def from_url(cls, url, *, loop=None, stream=False):
 loop = loop or asyncio.get_event_loop()
 data = await loop.run_in_executor(None, lambda: ytdl.extract_info(url, download=not stream))
 #print(data)

 if 'entries' in data:
 # take first item from a playlist
 data = data['entries'][0]
 #print(data["thumbnails"][0]["url"])
 #print(data["duration"])
 filename = data['url'] if stream else ytdl.prepare_filename(data)
 return cls(discord.FFmpegPCMAudio(filename, **ffmpeg_options), data=data)


Approximately the command to run the audio (from my bot) :


sessionChanel = message.author.voice.channel await sessionChannel.connect() url = matched.group(1) player = await YTDLSource.from_url(url, loop=client.loop, stream=True) sessionChannel.guild.voice_client.play(player, after=lambda e: print( f'Player error: {e}') if e else None) 


I searched for posts with the same error and they where either old or didn't solve my problem.


I tried importing instead of yt_dlp, I tried importing youtube_dl. But when I make the request it does not answer, no exception and no warning it just does not answer, as if the funcion is empty


I will link my other post that I asked. It might be usefull : Error : Unable to extract uploader id - Youtube, Discord.py
