multicast checker
1.0.0
研究项目
您使用脚本的风险由您自行承担
该项目包含2个脚本：
这两个脚本都兼容 python3 并使用 FFprobe 和 FFmpeg
使用前请先安装：
您可以简单地运行以下示例来查看它是如何工作的：
python3 multicast-checker.py --playlist playlist.m3u其中playlist.m3u是一个 M3U 文件，其中列出了所有 UDP 频道
M3U 文件示例：
#EXTM3U
#EXTINF:2,Info channel #1
udp://@233.99.65.1:1234
#EXTINF:2,Info channel #2
udp://@233.99.65.2:5500
#EXTINF:2,Info channel #3
udp://@233.99.65.3:1234
#EXTINF:2,Info channel #4
udp://@233.99.65.4:5500
#EXTINF:2,Info channel #5
udp://@233.99.65.5:1234
该脚本将使用多线程扫描 playlist.m3u 中的所有 schannel 并返回结果。 UDP 流中的 service_name 元数据字段将提前捕获。
输出示例：
[*] Email parameters are not defined.
[*] Run the script with -h parameter for the details.
[*] Channel Info channel #2 is not working
[*] Channel Info channel #4 is not working
[*] Channel Info channel #3 is not working
[*] Channel Info channel #5 is not working
[*] OK >>> Channel is working! >>> "Info channel #1" >>> No stream name found
[*] The following channel(s) are not working:
233.99.65.2:5500 - Info channel #2
233.99.65.4:5500 - Info channel #4
233.99.65.3:1234 - Info channel #3
233.99.65.5:1234 - Info channel #5
[*] Finished in 7.0 second(s)
python3 multicast-scanner.py --range 233.99.65.1/30该脚本将使用多线程扫描给定的 UDP IP 范围并返回结果。 UDP 流中的 service_name 元数据字段将提前捕获。如果找不到 service_name，则将捕获 10 秒样本。
输出示例：
[*] IP range to scan: 233.99.65.0/30
[*] IPs to scan: 4
[*] Ports to scan for each IP: 1
[*] List of the port(s) to scan: 1234
[*] Timeout for UDP stream reply: 5 sec(s)
[*] Timeout for stream data collection: 10 sec(s)
[*] Sample lenght in seconds: 60 sec(s)
[*] Totals:
[*] Total items to scan: 4
[*] Total number of /32 subnets to scan (# of threads): 4
[*] Total number of hosts for each subnet to scan: 1
[*] Estimated maximum time to complete the task: 50 seconds
[*] 0 day(s) 0 hour(s) 0 minute(s) 50 second(s)
[*] Found opened port 1234 for 233.99.65.1
[*] Scanning for 233.99.65.0/32 completed!
[*] Scanning for 233.99.65.2/32 completed!
[*] Scanning for 233.99.65.3/32 completed!
[*] !!! No channel name found for 233.99.65.1:1234 !!!
[*] !!! Channel added to the playlist. 233.99.65.1:1234 >>> 1 !!!
[*] Scanning for 233.99.65.1/32 completed!
[*] Recording the samples for unnamed channels...
[*] !!! Sample for 233.99.65.1:1234 captured !!!
[*] Finished in 14.0 second(s)
[*] 0.0 day(s) 0.0 hour(s) 0.0 minute(s) 14.0 second(s)
[*] Channels found: 1
