Please help downloading m3u8 video from kaltura

[xingxingjiang]

Hi,

There is a video from a kaltura link that I want to download via ffpmeg.

I've tried multiple variations of ffpmeg syntax to try and download it, with no success.

Here is one example

ffmpeg -i "https://cfvod.kaltura.com/hls/p/1067292/sp/106729200/serveFlavor/entryId/0_z3waapci/v/2/pv/4/flavorId/0_v7e2xtou/name/a.mp4/index.m3u8" -c copy index.mkv

One consistent error message I receive each time is " No trailing CRLF found in HTTP header."

I am able to download this video using a addon in firefox, but the download is so load that it always fails before the entire video is downloaded. I would like to use ffpmeg to download the entire video successfully.

Thanks in advance for any suggestions

I had no problem downloading the video with your command line.

I had no problem downloading the video with your command line.

I have no idea why it does not work for me.

What I tried using the command, I received this message

I just downloaded the most recent version of ffpmeg and I'm still getting the above error.

Thanks Jabago for testing this out. I'm not sure what I can do differently, but you have shown it is possible to download this video.

[xingxingjiang]

I am using Windows 10. I wonder if, Jagabo, you are using a different operating system and it could perhaps account for why you can download the video and it doesn't work on my computer. I'm just guessing about this.

[jagabo]

I'm using Win7. But I just tried it on a Win10 computer and had no problems. Maybe it's the Great Firewall that's causing your problem.
