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

FFmpegMediaMetadataRetriever returns setDataSource failed : status = > 0xFFFFFFFF
26 août 2015, par AlirezaThis is a weird error ! because it sometimes works but sometimes doesn’t work. I’m using FFmpegMediaMetadataRetriever to get the thumbnail from a video using an URL path.
retriever.setDataSource(((Video) obj).getVideoAddress());
return following error :java.lang.IllegalArgumentException : setDataSource failed : status =
0xFFFFFFFFThis is my code :
FFmpegMediaMetadataRetriever retriever = new FFmpegMediaMetadataRetriever();
Bitmap bmp;
retriever.setDataSource(((Video) obj).getVideoAddress
());
bmp = retriever.getFrameAtTime();Note : I checked the INTERNET permission and it exists. The problem is exists with some videos but with the same format ! I mean the only difference between videos is bit rates, length, size and others like this but not the file format.

avcodec_find_encoder(AV_CODEC_ID_H264) returns null
22 janvier, par Monjura RumiI am building an android application which will encode image captured from camera preview and later decode it. I am using ffmpeg library to encode and decode. To build static library with x264 I have used this tutorial. http://dl.dropbox.com/u/22605641/ffmpeg_android/main.html. As a source code of ffmpeg if I use the one downloaded from the link given in tutorial I can built it but can't build library if i use source code downloaded from here git clone git ://source.ffmpeg.org/ffmpeg.git ffmpeg. I have built library in ubuntu and using it in windows 7 in Eclipse. As I need only h264 encoder and decoder I have used following code for ffmpeg, slightly modified from tutorial.

build_one




After building library I have been able to build android ndk. A little part of my JNI code is here.



JNIEXPORT jint JNICALL Java_com_example_testjava_TestjniActivity_initencoder(JNIEnv* env,jobject obj){

 av_register_all();
 avcodec_register_all();
 codec = avcodec_find_encoder(AV_CODEC_ID_H264);
 if (!codec) {
 __android_log_write(ANDROID_LOG_INFO, "debug", "not found"); 
 return -1;
 }
.
.
.
}




When I run my java source code that calls initencoder() I get -1 as return value and logcat prints "not found". That means avcodec_find_encoder() returns null and if condition is being ok. I don't know what's wrong. Why this function is returning null ? I have searched a lot but did not find any solution that could guide me to right direction. some says to use avcodec_init(). But ndk-build command fails and shows error saying undefined reference to 'avcodec_init()'. I have started with library build because I thought may be I am doing wrong from the first stage. Did I make any mistake in library building like not enabling things that I should ? Please help me here. This is kind of urgent for me.
