• Error opening input files : Invalid data found when processing input

  27 mars 2024, par Master's Time

  I am creating disnake music bot. The error is :

  


  [in#0 @ 00000233f8d71500] Error opening input: Invalid data found when processing input
Error opening input file https://www.youtube.com/watch?v=duDUqBtxwXk.
Error opening input files: Invalid data found when processing input


  


  Here is part of my code :

  


  import disnake
import asyncio
from yt_dlp import YoutubeDL
import ffmpeg


YTDL_OPTIONS = {'format': 'bestaudio', 'noplaylist': 'False', 'simulate':'True', 'key':"FFmpegExtractAudio"}
FFMPEG_OPTIONS = {'before_options': '-reconnect 1 -reconnect_streamed 1 -reconnect_delay_max 5', 'options': '-vn'}


async def play_music(inter):
        global YDTL_OPTIONS, FFMPEG_OPTIONS
    print(tm.now().strftime("%H:%M:%S"),"play_music begin")
    id = int(inter.guild.id)
    with YoutubeDL(YTDL_OPTIONS) as ydl:
        info = ydl.extract_info(url, download=False)

    song = {
            'link': 'https://www.youtube.com/watch?v=' + url,
            'thumbnail': 'https://i.ytimg.com/vi/' + url + '/hqdefault.jpg?sqp=-oaymwEcCOADEI4CSFXyq4qpAw4IARUAAIhCGAFwAcABBg==&rs=AOn4CLD5uL4xKN-IUfez6KIW_j5y70mlig',
            'source': info['formats'][0]['url'],
            'title': info['title']
        }   self.vc[id].play(disnake.FFmpegPCMAudio(executable=r"C:\\ffmpeg\\ffmpeg\\bin\\ffmpeg.exe",source=song["source"], **FFMPEG_OPTIONS))
    print(tm.now().strftime("%H:%M:%S"),"play_music end")


  


  I tried to write source = song['source'] instead of source = song['link'], but it didn't seem helpful.

  


• pylwdrone and ffmpeg-python : pipe:0 : Invalid data found when processing input [closed]

  8 mai 2024, par Saail Chavan

  I am using a lewei camera on my drone and i have managed to get the stream using https://github.com/meekworth/pylwdrone, i want to do basic image processing like face or object detection or qr code scan which i am unable to do

  


  when i use this command in terminal :

  


  $ pylwdrone stream start --out-file - | ffplay -i -fflags nobuffer -flags low_delay -probesize 32 -sync ext -


  


  i get a clear feed with no errors

  


  enter image description here

  


  When i am using the script in python i am getting errors and the feed is bit lagged and skips frames

• FFmpeg can successfully retrieve the RTSP stream, but it cannot print the time_base

  18 septembre 2024, par 何西西

  I can successfully obtain the RTSP stream and use the av_dump_format function to print the stream information, but I cannot retrieve the time_base. Why is that ?
FFmpeg is version : n4.0.6

  


  this is my code :

  


  int main(int argc, char *argv[])
{
    struct timeval systemstart_time;
    struct timeval rtspfetch_time1;
    struct timeval rtspfetch_time2;

    AVFormatContext *pFormatCtx = NULL;
    AVPacket *av_packet = NULL;
    AVDictionary *options = NULL;

    gettimeofday(&systemstart_time, NULL);
    print_time_with_microseconds(systemstart_time);
    //av_register_all();
    avformat_network_init();
    const char *input_url = "rtsp://admin:Read1234@192.168.1.164:554/Streaming/channels/1";
    av_dict_set(&options, "buffer_size", "1024000", 0); 
    av_dict_set(&options, "rtsp_transport", "tcp", 0); 
    av_dict_set(&options, "stimeout", "5000000", 0); 
    av_dict_set(&options, "max_delay", "500000", 0); 

    pFormatCtx = avformat_alloc_context(); 
    printf("FFmpeg version1: %s\n", av_version_info());  
    //Open Rtsp Streaming
    if (avformat_open_input(&pFormatCtx, input_url, NULL, &options) != 0)
    {
        printf("Couldn't open input stream.\n");
        return 0;
    }
    gettimeofday(&rtspfetch_time1, NULL);
    print_time_with_microseconds(rtspfetch_time1);
    //Get Stream information
    if (avformat_find_stream_info(pFormatCtx, NULL)<0)
    {
        printf("Couldn't find stream information.\n");
        return 0;
    }
    gettimeofday(&rtspfetch_time2, NULL);
    print_time_with_microseconds(rtspfetch_time2);
    //Find if there is a video stream in the stream
    int videoindex = -1;
    for (int i = 0; inb_streams; i++) {
        printf("i: %d\n", i);
        if (pFormatCtx->streams[i]->codec->codec_type == AVMEDIA_TYPE_VIDEO) {
            AVRational time_base = pFormatCtx->streams[i]->time_base;
            mpp_log("time_base: %d/%d\n", time_base.num, time_base.den);
            videoindex = i;
            //break;
        } else {
            printf("Didn't find a video stream.\n");
            return -1;
        }
    }
    av_dump_format(pFormatCtx, 0, input_url, 0);  
}


  


  result :
the time_base in pFormatCtx->streams[i] is 0 ;

  


  time_base:0/0
Input #0, rtsp, from 'rtsp://admin:Read1234@192.168.1.164:554/Streaming/channels/1':
