A bit more info on a how to would be great. Even if it's a one line example of usage.

Please look at the updated readme for clarity.

Hi! I spent the whole day trying to make it work, with different video sources, with the multisegment and the single segment... always the same error. I am very new to phyton so hopefully it´s an easy-to-solve issue?

This is the message I keep getting: C:\Users\luis\DRM\dashdownloader.py:77: SyntaxWarning: "is" with a literal. Did you mean "=="? if video.status_code is 200: Traceback (most recent call last): File "C:\Users\luis\DRM\dashdownloader.py", line 142, in video_url,video_keyid,audio_url,audio_keyid = manifest_parser(mpd) File "C:\Users\luis\DRM\dashdownloader.py", line 65, in manifest_parser for prot in adapt_set.content_protections: TypeError: 'NoneType' object is not iterable

Any idea? Thanks!

[Jayapraveen]

Looking at the error, I suspect that the manifest has either no Content protection mentioned or is using cbcs or other cipher suites. If you could attach the manifest link, I could suggest you the modification needed.

[forhobbie]

Thanks! 2 examples I am after: https://shift72d-131.akamaized.net/50ca514a-f3a8-4fdf-a16f-9d5ee04fe4a2/236617/reel_rock_15.mpd https://dmf9cnjua2s32.cloudfront.net/media/AV2AW6FPZiChQ/ad38062f/stream.mpd I can also send you the links with the KEY in private if that helps

[Jayapraveen]

You can try the quickfix commit (d5fbdf1) for the mpd on cloudfront. For the other you'll have to use the multisegmented one. Before running the multisegment, modify the mpd parser for that manifest. You'll probably need to look at mp4box packaging (gpac) for info on how to modify the mpd parser.

[forhobbie]

Thanks. For the cloudfront, video and audio are downloaded (but encrypted?) , and I get on cmd the message "Key not found". Something I have to adapt on the keyfile.json? Elsewhere?

[Jayapraveen]

The script needs the key that was used to encrypt them in the first place. If you have the key and the keyID, you'll need to insert them in the keyfile.json without changing the format.

[forhobbie]

Yes, thanks. I did and it works perfectly. Great work, and thanks for sharing!

Hi. I'm having this error:

Traceback (most recent call last):
  File "D:\Downloads\Drm-Dash-stream-downloader-master\Drm-Dash-stream-downloader-master\dashdownloader_multisegment.py", line 213, in <module>

    second = seconds.match(period).group(1)
AttributeError: 'NoneType' object has no attribute 'group'

Do you know by any chance what's wrong?

[Jayapraveen]

The regex pattern for seconds failed to extract seconds information. I'm really unsure why it failed, Ill rollout a fix for this.

[AlvaroBeiro]

So did you find what was causing it? Because I have no clue.

[Jayapraveen]

Fixed in the latest release.

[AlvaroBeiro]

Now I'm closer, thanks! But still it throws an error:

    for segment in repr.segment_templates:

Thank you so much.

[Jayapraveen]

It is because you havent modified the mpd parser according to your manifest.

[miztertea]

It is because you havent modified the mpd parser according to your manifest.

I am having a similar issue:

Total time: 0 days 0 hours 44 minutes and 26.530312 seconds Processing audio/mp4 Media segments are of equal timeframe Traceback (most recent call last): File "dashdownloader_multisegment.py", line 212, in <module> media_info = manifest_parser(mpd) File "dashdownloader_multisegment.py", line 197, in manifest_parser for prot in repr.content_protections: TypeError: 'NoneType' object is not iterable

Can you help me understand what are some example moidfications to the mpd parser?

[Jayapraveen]

The MPD or Manifest contains the media information for Playback, We have to extract the Media information especially how the media is segmented , timeframe details , encryption scheme used and the url for the segments. The mpd parser function is used to grab those information. I have not used third party downloaders for downloading and merging the media segments as some vendors have made changes to the manifest to make thirdparty tools fail downloading properly, thats why we need to customize the function to every usecase.

1. The best way to make the customizations yourself is get the sample of the manifest.
2. Try to compare the iteration operation done by the mpdparser function on various attributes of the Manifest.
3. Once you have an idea on what each step of the function is doing, recreate the same according to your manifest file.

@fijo33, The mpd link should be replaced with the sample one in the driver code found at https://github.com/Jayapraveen/Drm-Dash-stream-downloader/blob/1d2d2edc6d7b87f08744cb7979e6e7843a90231c/dashdownloader_multisegment.py#L209

@fijo33, Need stack trace. Looks like the request to your manifest needs some authentication.

[Jayapraveen]

@steamupeu, You will need to modify the script as mentioned.

@fijo33, I can help you, if you give a better understanding of what youre trying to do, what you did and what didnt work out.

[andrewzhong1122]

Does this work with dynamic mpd? Thanks
