• Multiple download trim videos ffmpeg + youtube-dl [duplicate]

  4 décembre 2020, par sl4g

  I'm tryng to make a bash script to download and trim videos from URLs in a .txt file, using ffmpeg and youtube-dl. From the Internet I found this https://askubuntu.com/questions/970629/how-to-download-a-portion-of-a-video-with-youtube-dl-or-something-else and this How can I batch/sequentially download m3u8 files using ffmpeg ? and based on that I made this :

  


  #!/bin/bash

#only download the half of urls

HoldList="/home/user/desktop/dir1/code/bash/web.txt"

index=0
while read line ; do
    ffmpeg -ss 00:50:30 -to 00:51:00 -i "$(youtube-dl -f best --get-url $line)" -c:v copy -c:a copy output-${index}.mp4
    ((index=index+1))
done < "$HoldList"


  


  This code only downloads half of the videos. Download one, ignore the next, then repeat...

  


  How can I make not skip every other URL from the file ?

  


  I'm a newbie in Bash script (and in this site), and English is not my first language.

  


• Manifest error pops up when trying to download certain videos for discord.py music bot

  30 novembre 2020, par bork

  I'm trying to make a discord music bot. I'm using youtube-dl to retrieve the info and ffmpeg to play the audio out. My bot has no problems downloading videos and everything is working fine. But when I tried downloading certain videos, this error popped up :

  


  [dash @ 0x7fe45a801200] Manifest too large: 65055
https://manifest.googlevideo.com/api/manifest/dash/expire/1606336104/ei/CGq-X4G6Htauz7sPrZuCsA8/ip/14.192.212.39/id/64a943d43b8f53eb/source/youtube/requiressl/yes/playback_host/r5---sn-h5mpn-30ae.googlevideo.com/mh/Go/mm/31%2C29/mn/sn-h5mpn-30ae%2Csn-30a7rn7l/ms/au%2Crdu/mv/m/mvi/5/pl/24/hfr/all/as/fmp4_audio_clear%2Cwebm_audio_clear%2Cwebm2_audio_clear%2Cfmp4_sd_hd_clear%2Cwebm2_sd_hd_clear/initcwndbps/533750/vprv/1/mt/1606314038/fvip/5/keepalive/yes/beids/23927369/itag/0/sparams/expire%2Cei%2Cip%2Cid%2Csource%2Crequiressl%2Chfr%2Cas%2Cvprv%2Citag/sig/AOq0QJ8wRQIhAOn6Br0QsuXc-3unfhYdzXVXcydzVWioIQlKvv2U4i3OAiB6ApoiqFoPvE3YKYGPbRiId_bHQYO8zsawGGPMidYGAA%3D%3D/lsparams/playback_host%2Cmh%2Cmm%2Cmn%2Cms%2Cmv%2Cmvi%2Cpl%2Cinitcwndbps/lsig/AG3C_xAwRQIhANmxfRNBI4wSJo6trsKkq8GinQ-ADMxgHRmelBwM-GEAAiAafey9YRrZz1h1S6PzV3u0S6IsZUKscGrrGP9Pofv2uQ%3D%3D: Invalid data found when processing input


  


  After trying to download other videos, which have no problem at all, I found out that the videos showing these errors have an extra step that downloads MPD manifest. I would try to download videos that are way larger and it would work, but it's just these certain videos, with the duration of about 7-10 minutes, that would have these errors. I'm really lost.

  


  This is my code for playing the videos in the voice channels :

  


  voice = get(client.voice_clients, guild = ctx.guild)
with YoutubeDL(ydl_opts) as ydl:
                info = ydl.extract_info(url[playlist], download = False)

URL = info['formats'][0]['url']
voice.play(FFmpegPCMAudio(URL, **FFMPEG_OPTIONS))


  


• How can I download videos from reddit using praw

  9 octobre 2023, par rabbibillclinton

  So I want to download videos from reddit, I've seen projects on github but I'm very new to python and don't know how it works, if someone could explain I'd appreciate it, I found this project It works but it seperates audio and video and I want it all in one, I think you can combine those using ffmpeg but I don't know how that works either, also how do I configure some of this stuff like where the videos save and quality, here's my code.

  


  from redvid import Downloader
import praw

reddit = praw.Reddit(client_id = "a", client_secret = "b", user_agent = "c")

subreddit = reddit.subreddit("learnpython")
hot = subreddit.hot(limit=5)

downloader = Downloader(max_q=True)

for submission in hot:
    downloader.url = submission.url
    reddit.download()
