  • Youtube Dlp returns with error code of 400 [closed]

    10 mars 2024, par nikita goncharov

    I 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>

    &#xA;

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

    &#xA;

    import youtube_dl

    &#xA;

    or

    &#xA;

    import yt_dlp as youtube_dl

    &#xA;

    youtube_dl.utils.bug_reports_message = lambda: &#x27;&#x27;&#xA;&#xA;&#xA;ytdl_format_options = {&#xA;    &#x27;format&#x27;: &#x27;bestaudio/best&#x27;,&#xA;    &#x27;outtmpl&#x27;: &#x27;%(extractor)s-%(id)s-%(title)s.%(ext)s&#x27;,&#xA;    &#x27;restrictfilenames&#x27;: True,&#xA;    &#x27;noplaylist&#x27;: True,&#xA;    &#x27;nocheckcertificate&#x27;: True,&#xA;    &#x27;ignoreerrors&#x27;: False,&#xA;    &#x27;logtostderr&#x27;: False,&#xA;    &#x27;quiet&#x27;: True,&#xA;    &#x27;no_warnings&#x27;: True,&#xA;    &#x27;default_search&#x27;: &#x27;auto&#x27;,&#xA;    &#x27;source_address&#x27;: &#x27;0.0.0.0&#x27;,  # bind to ipv4 since ipv6 addresses cause issues sometimes&#xA;}&#xA;&#xA;ffmpeg_options = {&#xA;    &#x27;options&#x27;: &#x27;-vn&#x27;,&#xA;}&#xA;&#xA;ytdl = youtube_dl.YoutubeDL(ytdl_format_options)&#xA;&#xA;&#xA;class YTDLSource(discord.PCMVolumeTransformer):&#xA;    def __init__(self, source, *, data, volume=0.5):&#xA;        super().__init__(source, volume)&#xA;&#xA;        self.data = data&#xA;&#xA;        self.title = data.get(&#x27;title&#x27;)&#xA;        self.url = data.get(&#x27;url&#x27;)&#xA;        self.duration = data.get(&#x27;duration&#x27;)&#xA;        self.image = data.get("thumbnails")[0]["url"]&#xA;    @classmethod&#xA;    async def from_url(cls, url, *, loop=None, stream=False):&#xA;        loop = loop or asyncio.get_event_loop()&#xA;        data = await loop.run_in_executor(None, lambda: ytdl.extract_info(url, download=not stream))&#xA;        #print(data)&#xA;&#xA;        if &#x27;entries&#x27; in data:&#xA;            # take first item from a playlist&#xA;            data = data[&#x27;entries&#x27;][0]&#xA;        #print(data["thumbnails"][0]["url"])&#xA;        #print(data["duration"])&#xA;        filename = data[&#x27;url&#x27;] if stream else ytdl.prepare_filename(data)&#xA;        return cls(discord.FFmpegPCMAudio(filename, **ffmpeg_options), data=data)&#xA;

    &#xA;

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

    &#xA;

    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&#x27;Player error: {e}&#x27;) if e else None) &#xA;

    &#xA;

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

    &#xA;

    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

    &#xA;

    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 Alireza

    This 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 =
    0xFFFFFFFF

    This 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 Rumi

    I 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.

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

    &#xA;&#xA;

    JNIEXPORT jint JNICALL Java_com_example_testjava_TestjniActivity_initencoder(JNIEnv* env,jobject obj){&#xA;&#xA;    av_register_all();&#xA;    avcodec_register_all();&#xA;    codec = avcodec_find_encoder(AV_CODEC_ID_H264);&#xA;    if (!codec) {&#xA;      __android_log_write(ANDROID_LOG_INFO, "debug", "not found");                &#xA;       return -1;&#xA;    }&#xA;.&#xA;.&#xA;.&#xA;}&#xA;

    &#xA;&#xA;

    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.
