I found that the the link in the m3u8 file is a bmp file instead of mp4.


Does it matter ????
Can anyone tell me how to download the mp4 video file ?


Thank you for reading this !

How Can i Download this video ? Encrypted m3u8 ?
16 septembre 2022, par אורן NOHello everyone For almost a whole month now I have been trying to download a file from a specific site


This is the link to the video
https://www.karaoke.co.il/api_play.php?type=clip&id=58370&autoplay=undefined&referer=karaoketv


The M3u8 files are split into 2 parts.


Video file

And an audio file
https://www.video-cdn.com/video/encrypt/750802ea0bc2d02fac93adeaa1398ec2/750802ea0bc2d...2-57d9518fae69


As far as I know there is a Key that needs to be entered in order to download the file.


And when I run the command in ffmpeg


I encounter many errors like :
Unable to open key file


Anyone who can download it.
I would be very happy if he would write me a code that works and explain to me how to do it


These are all the codes I have already tried

FFMPEG - Download video in parts and concat, stutter at concat points
23 juillet 2022, par rnbwSmnMy goal is to download a video (or M3U8) in parts/chunks which I can later concat.


For context, I would like to download videos in an Android Service which may be stopped at any time, so I think chunking is the right approach.


After some time I got the "downloading the parts" right, using this. I would later put that in a function, and for now I chose the chunks to be 30 seconds long.


%offset% = 30 * %part%

ffmpeg -ss %offset% -t 30 -i INPUT_FILE -avoid_negative_ts 1 out%part%.mp4



The first line is just pseudocode, part is starting at 0.
This works fine, downloading 30 second long .mp4 files.


After that I tried merging them together into a single .mp4. For the tests I only downloaded the first few parts.


Concat command :


ffmpeg -safe 0 -f concat -i concat.txt -c copy final.mp4



This would be a very short concat.txt file :


file 'out0.mp4'
file 'out1.mp4'



The concat works but has one problem : At the point where both files are actually combined, so at 30 seconds, there is a small stutter in video and audio.


So what I think is going on is that I download parts that are 30s long, starting at multiples of 30s so there is a small overlap ? In the "Details" part of the Windows file properties it also shows a length of 31 seconds, so the video is even longer than I want.


I tried setting the duration of each part in the concat.txt, both to 30s and to 30s - 1 frame


23.98 fps -> 1/23.98 spf = 0.0417s



But with a duration of 30 as well as 29.9583, although it is better, there is still a small stutter.


file 'out0.mp4'
duration 29.9583
file 'out1.mp4'
duration 29.9583



I also tried with a different fileformat, .ts files, but the stutter was still there. I still think my timings are not quite right, but at this point I don't know where the problem is exactly. What do I need to change to remove the small stutter ?
