lavc : remove libfaac wrapper
29 septembre 2016, par Josh de Kocklavc : remove libfaac wrapper
There is really no need for two aac wrappers, we already have
libfdk-aac which is better. Not to mention that faac doesn’t
even support HEv1, or HEv2. It’s also under a license which is
unusable for distribution, so it would only be useful to people
who will compile their own ffmpeg, only use it themselves (which
at that point should just use fdk-aac).Signed-off-by : Josh de Kock <josh@itanimul.li>

Merge video with ffmpeg(or alternatives) with extra properties(an overlay)
28 juin 2021, par dconixDevI'll be scraping clips from twitch and merging them to create a single video file.
I already figured out the scraping of twitch clip links(but i only get 16-20 videos because i need to scroll with selenium but i dont really mind it, if you have a working solution then make an answer about it) and also the simple merging videos.


I'm scraping links with :


#!/usr/bin/python3.9
import bs4
import requests
import time
from datetime import datetime
from selenium import webdriver
from selenium.webdriver.firefox.options import Options

# Initialize driver and run it headless
options = Options()
options.headless = True
driver = webdriver.Firefox(options=options)

def extract_source(url):
 agent = {"User-Agent":"Mozilla/5.0 (Windows NT 10.0; rv:78.0) Gecko/20100101 Firefox/78.0"}
 source=requests.get(url, headers=agent).text
 return source

def extract_data(source):
 soup=bs4.BeautifulSoup(source, 'html.parser')
 names=soup.find_all('a', attrs={'data-a-target':'preview-card-image-link'})
 return names

driver.get('https://www.twitch.tv/directory/game/League%20of%20Legends/clips?range=24hr')

# I wait 3 seconds for the clips to get pulled in
# I'd like here to scroll down a bit so i can scrape more clips, but even after i tried some solutions my firefox(was debugging in GUI mode, not headless as it is now) wasnt scrolling
time.sleep(3)
extract_links=extract_data(driver.page_source)
for a in extract_links:
 print(a.get('href'))

driver.quit()

# I tried scrolling using this but didnt work, not sure why
# this script is supposed to scroll until youre at the end of the page
# SCROLL_PAUSE_TIME = 0.5

# # Get scroll height
# last_height = driver.execute_script("return document.body.scrollHeight")

# for i in range(3):
 # # Scroll down to bottom
 # driver.execute_script("window.scrollTo(0, document.body.scrollHeight);")

 # # Wait to load page
 # time.sleep(SCROLL_PAUSE_TIME)

 # # Calculate new scroll height and compare with last scroll height
 # new_height = driver.execute_script("return document.body.scrollHeight")
 # if new_height == last_height:
 # break
 # last_height = new_height


I'm joining videos together after downloading(with youtube-dl) with ffmpeg :


ffmpeg -safe 0 -f concat -segment_time_metadata 1 -i videos.txt -vf select=concatdec_select -af aselect=concatdec_select,aresample=async=1 out.mp4

Where videos.txt is as follows :


file 'video_file1.mp4'
file 'video_file2.mp4'
...


I can't really find answers on how to add a watermark(different for each video, although i found this it doesnt explain how to add a unique watermark to individual videos but the same watermark to two videos) without having to render each and every video twice but doing so in one go.


I think I stumbled upon some people who made their
videos.txtas follows in purpose of adding extra options to each video :

file 'video_file1.mp4'
option 1(for video_file1.mp4)
option 2(for video_file1.mp4)
file 'video_file2.mp4'
option 1(for video_file2.mp4)
option 2(for video_file2.mp4)
...


Would this work for unique watermarks for each videos(lets suppose watermarks are named video_file1.png, ... meaning the same as the videos, also the watermark is transparent in case that needs more configuration)
