  1. I used to successfully download 1080p videos from Channel 4 a month or two ago. Now it seems that video mpds don't list 1080p information. Only 576p is available at max. Am I doing something wrong? Can someone confirm this please with:
    Code:
    yt-dlp --allow-u -F "link-to-mpd"
    Sample video (which was previously downloaded in 1080p):
    Thanks!

  3. Thanks codehound. I realized my .mpd link has a filter parameter which limits display height to 576 pixels:
    Code:
    https://ak-jos-c4assets-com.akamaized.net/CH4_43_02_900_70914001001002_001/CH4_43_02_900_70914001001002_001_J01.ism/stream.mpd?c3.ri=13505210914841619937&mpd_segment_template=time&filter=(type=="video"&&((DisplayHeight>=288)&&(DisplayHeight<=576)))||type!="video"&ts=1650237886&e=600&st=ogfRm2mgvM_yxzaYgsXEJUz0Yluvf799U7N8mG6yV1E
    Now I only need to figure out why... Could be a limitation imposed on the user account I'm using.

  4. Are you using the top url in the address bar or using DevTools (F12) and filtering for mpd ?

    If you're using the mpd > click Response tab and you will see all the different / available resolutions towards the bottom

    The problem is that "Response" is generated based on the "&filter=[...]" string used in the .mpd request URL. With the .mpd link that channel4.com provides me, I can only see resolutions up to 1024x576... Any attempts to change anything in filter string results in "400 Bad Request". It would be interesting to figure out how to bypass this because even in your .mpd there's a filter with bitrate limitations. Removing those might uncover 1080p downloads with higher bitrates.

    So far, it doesn't seem to be a restriction imposed on my account. The problem is only reproducible with Chrome browser on my Linux lap top. Chrome on Windows successfully returns .mpd with 1080p streams.

  6. Did this ever get resolved? as i too seem to only be able to download 576p videos, and running the following:
    yt-dlp --allow-u -F indicates that there isn't a 1080p option available? anyone else getting this odd behaviour?

  9. No not using Linux, using Win7 with Chrome, it's everything i've tried over the last few weeks, but the last thing was this i interrogated the server and it's saying no 1080p only 1024x576 max, which is very strange.

    the problem isn't win7 or w10/11, but the browser: it seems that any browser not reply with an mpd with high resolutions (1080p)
    but the only one that gets an mpd with 1080 is edge browser
    so, if you don't have/use edge, install extension at post#11, then select OS win, browser edge

    with this with whatever browser you use it seems to be edge browser
    and with this trick you get a "special" mpd with 1080p

  18. Hi all,

    I ran the command and obtained the list, as showed in the codehound's screenshot.

    What command must I do to then download the files that I want from the list?

    (When I run the command without the --f argument, it downloads a m4a file and a mp4 but they won't play in VLC).

    you don't play audio/video because both are encrypted ... read some other threads on this forum

  20. Thats because they are encrypted. You need the decryption key to decrypt both. Then merge the decrypted video and audio together with ffmpeg or mkvmerge.

    If you post or PM the name of the program someone may provide the keys. If you were unaware of the encryption here; there is no way you will be able to obtain the keys yourself.
