Description

WRITE DESCRIPTION HERE

This is reference to the following issues:

• here,

• here

Kindly add support for AES-128 encrypted HLS videos (such as those streamed via edugyaan.com)

If needed, credentials can be emailed.

Oh! I see! I forgot to add the Example URLs. They could be found in the first issue I listed. But I understand that they must have been mentioned here for everyone's reference.

Please find then below:

• Single video: https://5ad66d227b0c1.streamlock.net/edusecure/_definist/64/1212/5042/121513/64_1212_5042_121513_0.mp4/chunklist_w1422491268.m3u8?isPrimary=true&ref=http%3A%2F%2Ftheiashub.edugyaan.com&sessionId=1l0gahmb2ueads99d190bfcnn4&userId=231644&username=singhal.shagun%40gmail.com&videoId=121513

There are no playlist URLs. The M3U8 playlist URL mentioned above contains partial URLs of the various TS segments.

Further, the above mentioned URL may not work....it keeps changing...especially the sessionId and the chunklist suffix. For a working URL, one would need to fetch a working M3U8 URL by logging into the account for which credentials can be emailed.

[remitamine]

no, post the URLs of the original webpages, not the m3u8 manifest, and verbose log of the command used.

[ComputerUser-CU]

Oh! I've updated the original post with an example of a single video webpage on this website.

Regarding account credentials, please email me at lastaspiration@gmail.com. I'll share the credentials there.

If there are any better sharing mechanisms, kindly do let me know. I'll share the credentials via the same.

I can confirm that @remitamine's suggested modifications in hls.py in this thread did indeed help me download the entire video file. However, with respected to videos downloaded with --hls-prefer-native

1. In absence of FFMPEG, youtube-dl reported malformed AAC bitstream. And the downloaded video couldn't be played either by VLC or by Potplayer.
2. In presence of FFMPEG, youtube-dl went on the fix the malformed AAC bitsream. However, the resultant videos were truncated. e.g.: As against the expected duration of 2 hours 40 minutes, a resultant video was only 30-odd minutes long.

In case I used FFMPEG to download the videos,

1. FFMPEG would sometimes download all the fragments of the video, but write only the fragments worth initial few minutes into the MP4 file;
2. Sometimes FFMPEG would not download the later fragments at all and throw some encryption-related error
3. FFMEG isn't able to resume the file downloads in case it's disrupted/breaks. It always starts downloading from the scratch.

In either case, neither the HLS downloader nor FFMPEG were able to download and reproduce complete video files.

For example, the HLS native downloader produced this file:
https://drive.google.com/open?id=1M8gJMd_-OhX6qJD5KTxBHkavU64w-_WY

It cannot be opened even by VLC. Handbrake as well as ffmpeg say "moov atom not found".

Here is the log of when I try to perform any ffmpeg operation on this file:
