How to download certain time (number of seconds) live M3U8 link and save?

[zydjohn]

Hello:
I can use the following command to download some live sports stream, like this:
C:\Videos\Download>youtube-dl.exe https://m3u8.1proxy.xyz/media/g_03/playlist.m3u8 --external-downloader ffmpeg --referer "https://bingsport.com/" -o test_video.mp4
But the live stream seem never ends, for example, for one soccer game, 99% of the games will end within 2 hours, unless it has over-time or even penalty shot out. Therefore, I want to set a time limit, like 2 hours (7200 seconds) for such M3U8 link, it seems ffmpeg has such option, but I don’t know how to convert the above command to ffmpeg.
Please advise on how I can either convert the youtube-dl command to ffmpeg command, or if youtube-dl/YT-DLP has similar option to set a time limit like ffmpeg -t option.
I have tried to Ctrl+C to stop the download, but the result file, no matter what name (like: test_video.mp4) I gave, it is not playable on any of the media I have.
So, trying manually stop this kind of download is not working!
Thanks,

here is another example:

yt-dlp --external-downloader ffmpeg --external-downloader-args "ffmpeg:-t 02:00:00" --referer "https://bingsport.com/" -o test_video.mp4 "https://m3u8.1proxy.xyz/media/g_03/playlist_gtom.m3u8"

or you can change 02:00:00 to 7200
