Python+ffmpeg realizes multi-threaded downloading, decryption, merging into MP4 and output of TS video in m3u8 file.

編輯：Python

demand ： Download the movie from the target website to the local .

Target site movies ：《 Adventure in the jungle 》 Watch the movie online for free _ Apocalypse cinema

Analysis website ：

1, According to web page analysis Of the film m3u8 It's on the index.m3u8 in , There are two in the web page index.m3u8, Choose the second .（ How to analyze a web page , I won't discuss it here ）

download m3u8 file

# download m3u8
def down_m3u8(url):
resp = requests.get(url, headers)
text = resp.text
with open(" Adventure in the jungle .m3u8", "w") as f:
f.write(text)
print(" Adventure in the jungle .m3u8 Download complete ")

2, Yes, downloaded m3u8 analysis , Here you will find that there is a process AES-128 encryption ,ts The video will not play after downloading , So you need to decrypt .

Using multi thread download ts video

# Use thread pool to download m3u8 Inside ts
def down_ts():
with open("./ Adventure in the jungle .m3u8", "r", encoding="utf-8") as f:
# n = 0
with ThreadPoolExecutor(10) as t:
for n, line in enumerate(f):
line = line.strip()
if line.startswith("#"):
continue
t.submit(ts_video, n, line)
# download ts video D:\\data\\movie_ts\\m1 Download for ts Video storage path
def ts_video(n, line):
# Download Video
resp3 = requests.get(line)
with open(f"D:\\data\\movie_ts\\m1\\{n}.ts", "wb") as f:
f.write(resp3.content)
print(n, " Download complete ")

3, The video downloaded here is encrypted , Can't watch directly in the player , The next step is to encrypt the downloaded data ts Decrypt the video

Decrypt ts video

# Yes, download t well ts Decrypt the video D:\\data\\video\\m1\\ After decryption ts Storage path
def jiemi():
f = open("./ Adventure in the jungle .m3u8", "r", encoding="utf-8")
keys = []
for file in f:
key = re.findall(r'URI="(.*?)"', file) # Match with regular key
if key:
keys.append(key[0])
key_url = keys[0]
resp4 = requests.get(key_url)
key = resp4.text
key = key.encode("utf-8")
aes = AES.new(key=key, IV=b"0000000000000000", mode=AES.MODE_CBC)
download_path = "D:\\data\\movie_ts\\m1"
all_ts = os.listdir(download_path)
li = []
for i in all_ts:
i = i.split(".")[0]
li.append(int(i))
li.sort()
for i in li:
with open(f"D:\\data\\movie_ts\\m1\\{i}.ts", mode="rb") as f1, \
open(f"D:\\data\\video\\m1\\2000{i}.ts", mode="wb") as f2:
bs = f1.read()
f2.write(aes.decrypt(bs))
print(f" The first {i} Video processing finished ")

Decrypt okay ts video

Decrypt okay ts Video can be viewed directly with the player

4, Good for decryption ts For video ffmpeg synthesis MP4 video

You need to install ffmpeg

Windows:

1. Get into http://ffmpeg.org/download.html#build-windows, Click on windows The corresponding icon , Enter the download interface and click download Download button ,
2. Unzip download okay zip File to specified directory
3. Put the extracted files in the directory bin Catalog （ contain ffmpeg.exe ） Added to the path In the environment variables
4. DOS Command line input ffmpeg -version, The following interface appears to indicate that the installation is complete ：

Mac ( Open the terminal (Terminal), use homebrew install ):

brew install ffmpeg --with-libvorbis --with-sdl2 --with-theora

Linux:

apt-get install ffmpeg libavcodec-extra

ffmpeg synthesis MP4 video

# Good for decryption ts For video ffmpeg synthesis MP4 video
def movie_video():
filePath = "D:\\data\\video\\m1"
file_list = os.listdir(filePath)
li = []
for file in file_list:
file = file.split(".")[0]
li.append(int(file))
li.sort()
ts_file_name = []
for i in li:
i = str(i) + ".ts"
ts_file_name.append(i)
with open("D:\\data\\video\\m1\\file_list.txt", "w+") as f:
for file in ts_file_name:
f.write("file '{}'\n".format(file))
print("file_list.txt The generated ")
txt_file = "D:\\data\\video\\m1\\file_list.txt"
mp4 = "D:\\data\\movies\\ Adventure in the jungle .mp4"
cmd = f"ffmpeg -f concat -i {txt_file} -c copy {mp4}"
try:
os.system(cmd)
except Exception as e:
print(e)
print("done")

Tips ： When the code runs to Pictured Shown , Here is in the composite video , It takes time , Just wait patiently for the completion .
