Here is a Python version to obtain the pssh code for the video from the fastevo.com video:

Code:

    response.raise_for_status()
    return response.text


def extract_kid(mpd_xml: str) -> str | None:
    """Extrait le default_KID du MPD."""
    match = re.search(r'cenc:default_KID="([^"]+)"', mpd_xml)
    if not match:
        return None
    kid = match.group(1).replace("-", "").lower()
    if len(kid) != 32:
        raise ValueError("Longueur KID invalide (doit faire 32 caractères hex).")
    return kid


def build_widevine_pssh(kid_hex: str) -> str:
    """Construit un PSSH Widevine à partir d'un KID hex."""

    pssh_box.extend(bytes.fromhex(kid_hex))
    size = len(pssh_box)
    pssh_box[0:4] = size.to_bytes(4, byteorder="big")
    return base64.b64encode(pssh_box).decode()


def main():
    url = input("Entrer URL MPD : ").strip()
    try:
        mpd_xml = download_mpd(url)
        kid = extract_kid(mpd_xml)

thanks for the script.
But how to exactly trick the license server into giving you the keys.

Just discovered this thread in my rabbit hole research and I'm a bit at my wits end, does anybody have any updates to a solution on this issue?

Fastevo seems to break the normal download workflow. Here's what I found out so far according to my understanding (don't burn me at the stake, I literally started reading about the entire topic just earlier today):

1. Vineless extension does not seem to recognize it, while WidewineProxy2 does. It might be because according to @larley Fastevo have deactivated ClearKey, which may render Vineless useless here.

2. Despite trying with multiple different L3 CDMs that have been public and also extracting my own L3 CDM from an AVD from a Google Desktop emulator via KeyDive, you can download the raw binary data but it fails to decode. WVP2 recognizes the DRM sequence and gives you a working N_m3u8DL-RE command but decrypting using Shaka doesn't work, it always ends up with failing to decode the first frame:

[h264 @ 0x55ec14763e00] top block unavailable for requested intra mode -1
02:06:21.928 WARN : [h264 @ 0x55ec14763e00] error while decoding MB 0 0, bytestream 21857
02:06:21.933 WARN : [aac @ 0x55ec14763e00] SBR was found before the first channel element.
02:06:21.934 WARN : [aac @ 0x55ec14763e00] invalid band type
02:06:21.934 WARN : [mp4 @ 0x55ec148f6300] track 1: codec frame size is not set
02:06:21.971 WARN : [mp4 @ 0x55ec148f6300] aac bitstream error

rendering the file unplayable.

3. The KID is extracted correctly, looking at the MPD XML definition anyway. PSSH I'm not sure but should not be the issue. Sending a request to the licensing server https://api.fastevo.net/service/api/v1/mediaprotection/licenses/wv is not straight forward. If I try to use pywidevine directly, it just gives me 401 unauthorized, but that's maybe because header replication hasn't happened. So I tried replicating a valid request by copying the request headers from a valid license exchange with specific reference to Authorization and X-Signature like @sesamap159 suggested and I get a 428 Precondition Required answer with a non-descript JSON object with 3 attribute keys, "e", "i" and "k" , which I also neither know what that means, nor is it helpful in any obvious way.
The license request payload and answer are all seemingly running through protobuf stuff, the type specified is application/octet-stream so I'm also unsure how do use any of this.

Since things are playable on a normal ChromeCDM in a non-mobile browser, I don't really know where to go from here, they might change the keys according to CDM like mentioned here https://forum.videohelp.com/threads/416316-%5BRelease%5D-WidevineProxy2-Extension-Bypa...rapping/page24 and give out invalid keys for certain captured CDMs (? not even sure this is possible) but I don't know.

Any help or insight appreciated.

How did you get the correct keys? My WVP2 generated command does not seem to work, the keys from the license server are wrong. If I execute yours it works without problems. As far as the MPD files are concerned, they are mostly the same between my stream and yours. Mine contains more <AdaptionSet> but that's about it.
Regardless of what I do, I cannot decode the videostream. Thought I'd try to use your User-Agent but that makes no difference. Even if it made no sense I actually tried to use the keys from your example but that doesn't help either. Something about this set of keys doesn't work:

--key 69c628ccae01bc623001249000000000:9c8fba808a5340bef 49cb0d507732928

Fastevo seems to break the normal download workflow. Here's what I found out so far according to my understanding (don't burn me at the stake, I literally started reading about the entire topic just earlier today):

1. Vineless extension does not seem to recognize it, while WidewineProxy2 does. It might be because according to @larley Fastevo have deactivated ClearKey, which may render Vineless useless here.

2. Despite trying with multiple different L3 CDMs that have been public and also extracting my own L3 CDM from an AVD from a Google Desktop emulator via KeyDive, you can download the raw binary data but it fails to decode. WVP2 recognizes the DRM sequence and gives you a working N_m3u8DL-RE command but decrypting using Shaka doesn't work, it always ends up with failing to decode the first frame:

[h264 @ 0x55ec14763e00] top block unavailable for requested intra mode -1
02:06:21.928 WARN : [h264 @ 0x55ec14763e00] error while decoding MB 0 0, bytestream 21857
02:06:21.933 WARN : [aac @ 0x55ec14763e00] SBR was found before the first channel element.
02:06:21.934 WARN : [aac @ 0x55ec14763e00] invalid band type
02:06:21.934 WARN : [mp4 @ 0x55ec148f6300] track 1: codec frame size is not set
02:06:21.971 WARN : [mp4 @ 0x55ec148f6300] aac bitstream error

rendering the file unplayable.

3. The KID is extracted correctly, looking at the MPD XML definition anyway. PSSH I'm not sure but should not be the issue. Sending a request to the licensing server https://api.fastevo.net/service/api/v1/mediaprotection/licenses/wv is not straight forward. If I try to use pywidevine directly, it just gives me 401 unauthorized, but that's maybe because header replication hasn't happened. So I tried replicating a valid request by copying the request headers from a valid license exchange with specific reference to Authorization and X-Signature like @sesamap159 suggested and I get a 428 Precondition Required answer with a non-descript JSON object with 3 attribute keys, "e", "i" and "k" , which I also neither know what that means, nor is it helpful in any obvious way.
The license request payload and answer are all seemingly running through protobuf stuff, the type specified is application/octet-stream so I'm also unsure how do use any of this.

Since things are playable on a normal ChromeCDM in a non-mobile browser, I don't really know where to go from here, they might change the keys according to CDM like mentioned here https://forum.videohelp.com/threads/416316-%5BRelease%5D-WidevineProxy2-Extension-Bypa...rapping/page24 and give out invalid keys for certain captured CDMs (? not even sure this is possible) but I don't know.

Any help or insight appreciated.

You have described my first 14-days battle very correctly.. i was even able to decode their protobuf from pages that showed the video.. but even that still gave me wrong keys so i went back to square one.. i did found out that the header you use for "N_m3u8DL-RE" does not matter

i have still 2 venues open(maybe will work, maybe will not):
currently building a chrome version where i can scan network activity to get keys
currently reverse engineering their JS and trying to build a tampermoney script to get keys

Good to know, it's rather frustrating that Fastevo's key behavior on some sites is extremely strange. The documentation on their part is also not that extensive so it's hard to gauge through the obfuscation what's what.

There is an option that I thought about using an injected version of GoogleCDM that may sniff out the keys using something like a customized CDM build but I'm not sure if that's of any help. Injecting something via Tampermonkey for the intermediate JS layer for the Mediaplayer might be better suited but idk.
Either solution is unusually complicated for just this one vendor's key system.
I wonder if WVP2's original author @larley has any insights they could share.

Hi, I'm in the same boat. Got some keys but the vid downloaded is still encrypted. Got my CDM keys from an AVD
