• Short HLS MPEG2 Video Segments Do Not Play

  24 août 2019, par Jon H

  I’ve been attempting to cut a video into small segments (words), to be rearranged. While I’ve been able to do it with FFMPEG, cutting into segments and using the fast concat demuxer to reassemble the segments, I am trying to speed it up.

  I have been doing this by splitting the original video into short MPEG2 .ts segments for each word :

  ffmpeg -ss 1 -to 1.5 -i "source.mp4" -c:v libx264 -b:v 1200k -c:a aac -b:a 192k -hls_flags single_file "word.ts"

  I have then tried making a m3u8 playlist of these short video segments, but I found that only segments around 2 seconds or more, play at all.

  I then tried using the ’cat’ command to join these segments into a single file, which I understand should be possible with MPEG2 streams. However, this did not play all the segments either.

  To test if all the segments were present in this concatenated file, I used FFMPEG to convert it back into an MP4 file, and all the segments were present.

  I would appreciate any suggestions on producing the segments, and concatenating individual segments simply without FFMEPG. My project isn’t viable if having to call FFMPEG each time, but would work great if I can simply concatenate words together.

• 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.
