Using youtube-dl error

[joejim]

I sniffed URL from Video DownloadHleper. It's ESPN live broadcast.
then I tried to download using youtube-dl.

command line: youtube-dl https://nlcache6.streamlive.to/edge/xoaaohmeuajfeyf/chunks.m3u8?nimblesessionid=408522...VuPTIwJmlkPTA=

Then I got this error. in red letters.
At line:1 char:100
+ ... e.to/edge/xoaaohmeuajfeyf/chunks.m3u8?nimblesessionid=408522&wmsAuthS ...

Interesting thing is same URL sniffed by Video DownloadHelper is recording fine by Video DownloadHelper.
(I think Video DownloadHelper is also using youtube-dl to download??)
So why youtube-dl is not working for same url?

Need link.

[codehound]

Without a link to the video you are trying to download, no one can help you as we dont know whether you have the correct m3u8 file. We need to get that ourselves. But with it being an espn account I assume it will need a login.

And maybe read correctly what the yt-dl error message is saying. If you have an & character in your syntax your m3u8 will need " at the beginning and " at the end.

[joejim]

I did post the link. Here it is again.

https://nlcache6.streamlive.to/edge/xoaaohmeuajfeyf/chunks.m3u8?nimblesessionid=408522...VuPTIwJmlkPTA=

It's from ESPN channel, website is https://www.streamlive.to/view/48051/ESPN-(HD)
as I said I sniffed URL using Video DownloadHelper
It's free, there are many channels including ESPN.

[joejim]

I wanna repeat again, This is not a video. It is a LIVE ESPN broadcast like you would watch on cable tv.
There are other channels like CBS, CNN, NBC, FOX, etc...
Also there are other website have LIVE broadcast channels.
http://kmedia.io/ , http://123tv.live/watch/espn/

So again question is why addon like Video DownloadHleper can down load it but using youtube-dl, I get error?

[joejim]

The reason for my question is I think I can get better result downloading using youtube-dl than Video DownloadHelper .
Cus Video DownloadHelper is not always reliable.

Also another clarification. I said "download" but I mean recording LIVE broadcast channel.
It's not a video download.

Think of is as your are watching LIVE sports game(which is not a video) on a channel, and you wanna record it.
How can you use youtube-dl to record the LIVE game?

[LZAA]

youtube-dl --no-part --hls-use-mpegts --referer http://123tv.live/watch/espn/ "http://tmedia.me/espn/espn1-p-4500/espn1-p-4500.m3u8"

[joejim]

youtube-dl --no-part --hls-use-mpegts --referer http://123tv.live/watch/espn/ "http://tmedia.me/espn/espn1-p-4500/espn1-p-4500.m3u8"

WOW, Thanks LZAA, that worked. Few follow up questions.

After I Cntl-C to stop recording, I got final MP4 file. I didn't see any .part files downloading before I stopped youtube-dl.
Does this mean MP4 file is downloaded directly?
I ask this cus when I was using Video DownloaderHelper(VDH) sometimes VDH just stop recording. Then I loose recording.
When VDH was downloading .part files first then aggregate to MP4 later, I loose all recording.
Then I figured out how make VDH download M2TS file, then even is VDH stops, I still got what's been recording.
So if for some reason youtube-dl stops (not by me), will I have what's been recorded already? in MP4 format?

LZAA:
Can you try this website?
http://yoursports.stream/live.php?v=espn
URL is http://ak-hls-brs-espn1.espn.go.com/hls/live/218616/p/espn1-p-4500/espn1-p-4500.m3u8
So I tried youtube-dl command as you can see below.
But I got an error. See below error result.
I think this website is "protected" or something. It will let me play it only on browser but not record.
(too bad cus http://yoursports.stream is great site. Streams fast and never buffers watching LIVE, Only if I can record? LOL)
When I try VDH, it gives me Response Code 400(bad request).

LZAA:
Have you tried VDH(Video DownloadHelper)? Maybe you know already?
It's Firefox/Chrome addon.
Perhaps you can install VDH and test these websites, and compare recording in VDH to youtube-dl command?
I be very interested hearing your comments.

Here are few sites that you can play with.
http://yoursports.stream/ All sports.
http://123tv.live and http://kmedia.io/ , ESPN, NFL, CBS, ABC, etc...

Thanks,

[joejim]

After I replied, I learned more about youtube-dl.
I see that TS chunks are download and I can play it in mpv player during recording. That's same as VDH downloading M2TS that I can watch during recording. WOW.

I am watching NFL, Steelers/Panthers now. So I am recording in VDH and youtube-dl.
At first youtube-dl recorded fine, then computer froze, reboot.
Now VDH is recording but youtube-dl give me error.

I am not what all that means but something to do with can't access source anymore?

Anyway it was a nice learning about youtube-dl, but I think for simple user like me, just stay with VDH and live with whatever happens.

Thanks for your time.
