    Hi,
    I'm using a locally based Israeli TV operator named NEXTTV.co.il (NOT the Chinese based NextTV streaming service).
    I would like to save a local copy of my intended program to watch offline on my laptop, since my resources are somewhat limited for streaming - old A8 smart phone, no TV / smartTV, so can't watch live TV - only VOD with my laptop and ONLY when home network is free

    HLS streaming is encrypted [not sure about method of encryption though] so regular browser extensions (downloadhelper/ HLS downloader/ etc) wouldn't do the trick.

    I understand that forum rules forbid subscription materials, but in my case I really believe I do not violate the rules;
    Web based client does require login details (based on Israeli ID details and phone number) but this is a local TV operator (which only operates in Israel) that also aires public broadcast local programs which is only what I'm trying to save for personal viewing (programs that aired on the regular TV channel which I couldn't watch OTA/FTA as I don't have a TV, just the laptop).

    I've tried simple ffmpeg commands such as:
    ffmpeg -i 'url' -c copy video.ts

    but I get HTTP error 403 Forbidden, I'm not sure if i'ts because I need to add HTTP headers, or provide some other type of authentication method (login details, cookie...)

    As I'm quite a novice, I would really appreciate it if someone can help me with step by step trial and error command guide that I can try till I to get it right.


    Below is an example hit details for a sample program via video download helper (I understand session expires so I need to recheck every time I try again).

    [Thx in advance!]

    hmm...
    I'm not a developer so I don't have any experience with chrome dev tools.
    from what I can see all kinds of cookies are being called for.
    I've attached a photo of the console panel with a cookie query wherein what I think the relevant cookie might be are expanded.
    [portal.mk-sense.com and hotjar.com].
    I hope this is what you were referring to and is the in the right context, please forgive me if I'm not correctly contextualizing it.
    If something more specific is required, may you please direct me with a step by step where to pinpoint and focus on.
    I should also mention that as part of the first viewing process it required me to install a chrome extension called "Player for NextTV content".
    Below is also the ffmpeg output:

    ok, PSB what I actually filtered on screen (sorry if it's no exactly as mentioned as I filtered by url beginnig since i couldn't locate a cookies tab).
    And PSA captured HRA log, which I hope will be of better use.

    Hey,
    By any chance were you able to look at the last log I sent?

    Thank you for all the help.

    So I'm sure that I need to provide some cookie for authentication, since I can still watch video even after 24hr or re-opening the browser, without logging in again.
    So all I need is for someone to help identify the coookie and how to set it via ffmpeg.

    By any chance can someone take a look I provided in the thread (it's still the same session), and help out?

    Thanks in advance.

  9. Save your Fiddler session. Give the file.

    Hi,
    Sorry for the delay (time differences).
    In order to simplify things and keep size to a minimum I preformed the following scenario:
    1.Open chrome browser (where initial login was performed and nexttv app is installed)
    2. Start fiddler capture
    3. enter main portal https://www.nexttv.co.il/ --> portal displays not logged in (in hebrew)
    4. click on any new video --> portal displays connected, no login required again (this is were credentials where fetched in some way)
    5. start playing video
    6.stop capture

    fiddler session doesn't detect any cookie sent/set under request/response in accordance (I've tried this scenario a couple of times).
    So I'm a little confused, perhaps an external server is used to manage credentials and this was performed only when I was prompted to login initially at the beginning.
    [I'm a little reluctant to play around and clear chrome cache to see what happens;
    as this is working at the moment and I'm not prompted to re-login, wherein all the attached logs in this thread pertains to it]

    Is there a way around this??
    I'm not entirely sure how to analyze and interpret this simple scenario log, hope you might lend a hand and see what is missing in order to make some progress...

    Thanks in advance!

  11. Configure HTTPS in Fiddler. Save your Fiddler session. Give the file.

    OK, exact same scenario with capture https enabled in fiddler, obviously much bigger in size...
    (sorry about that, wasn't aware it's not on by default, I haven't worked with fiddler before, just a little wireshark).
    PSA

    Thx!

  14. I looked at the log. This is not an easy task. There is no solution yet. I'll write if I can decide.

    I see, so it's not just a one liner ffmpeg command with a few more variables which I thought I just needed a little help to identify and integrate correctly.
    If you com to realize that this will require a lot more extensive analysis and to and fro, then perhaps it's not worth the effort (it might even be easier to acquire an actual complaint TV set).
    Please just let me know when you come to a decision as you noted.

    Thanks for the effort regardless of the final outcome...
