Download range #622

raducostea · 2013-01-08T07:55:19Z

Hi,

Is there any way to implement a download range? To download starting from 1m 30 to 1m 50?

Thanks

phihag · 2013-01-08T09:01:21Z

This is request is more complex than it sounds:

At first, we need to be able to download byte ranges. That is fairly easy and possible, but still needs to be implemented and tested.
Then, we need a way to determine which bytes correspond to 90s and 110s, most likely by peeking into the first or last bytes of the file.
Finally, you probably want a full video file, and not a video sequence. We need to reassemble that sequence.

All, in all, this is quite complex, but certainly doable. Feel free to contribute patches or pull request, even for the individual steps.

Hi,

I've tried to implement the Byte Range and it worked but of course the video will not play. Probably i need to reassemble the sequence somehow

phihag · 2013-01-08T11:52:47Z

Feel free to submit a pull request for the byte range. It's far easier to integrate code in small steps than all at once, and others may chip in.

hi guys,

this feature is super important for us. any updates on this issue?

Hi
How could I Download bytes-ranges via youtube-dl?

Thanks

yasoob · 2013-06-30T19:11:15Z

@shaybracha today its too late. I will see tomorrow and will tell you. 👍

shaybracha · 2013-07-01T06:37:54Z

@yasoob thanks...waiting for your answer

yasoob · 2013-07-01T15:12:54Z

Sorry I was not able to do it today because my laptop broke :( okay you
will have to use an external script to get the bytes value.make your own
python script. You can import youtube-dl and extract the info then you can
use requests with stream=true to get the byte range . This is the
procedure. However I will post the complete code in 1 or 2 days after I get
my laptop repaired. Thanx for your patience.

This is fairly easy to accomplish with ffmpeg. Example:

ffmpeg -ss (start time) -i (direct video link) -t (duration you need) -c:v copy -c:a copy (title.mp4)

You can get the direct link by using the --get-url option.

I don't know this projects feelings on adding (optional) dependancies, but this would be trivial to implement provided ffmpeg (compiled with open-ssl) is available. If adding the dependency is not an option, then, as I'm sure you're all aware, this is a pretty mammoth task.

Users who have ffmpeg installed can use method this in the meantime.

mk-fg · 2015-05-19T11:42:30Z

For current twitch.tv VoDs, byte-range is not necessarily needed, as they are split into 4-second chunks, and m3u8 playlist specifies all the chunk lengths precisely (e.g. #EXTINF:3.240,), so if ~4s seek precision is tolerable (which it probably is) - it's only a matter of running through playlist to pick the links needed.

I did write a proof-of-concept script for that here, and it seem to work nicely, except for some sequential download performance issues, which kinda rule-out downloading whole thing with ffmpeg directly.
Did a write-up on on the whole process here.

roberto68 · 2015-12-06T15:04:56Z

@JaySandhu please provide some complete example: cause I did this: ffmpeg -ss 14350 -i https://www.youtube.com/watch?v=mMZriSvaVP8 --get-url -t 11200 -c:v copy -c:a copy react-spot.mp4
and it did not work.

JaySandhu · 2015-12-06T19:15:45Z

@roberto68 Sorry for the confusion, to get a direct link to the video you need to use youtube-dl's --get-url option. Then, with a direct video link from youtube-dl, you can use ffmpeg as described above.

Example:
youtube-dl -f 22 --get-url https://www.youtube.com/watch?v=mMZriSvaVP8

Then with the link:
ffmpeg -ss 14350 -i (link) -t 11200 -c:v copy -c:a copy react-spot.mp4

One line version:
ffmpeg -ss 14350 -i $(youtube-dl -f 22 --get-url https://www.youtube.com/watch?v=mMZriSvaVP8) -t 11200 -c:v copy -c:a copy react-spot.mp4

You can either pick a format with both video and audio (such as -f 22), or you can use ffmpeg to combine a DASH audio and video stream. You'll need to make sure you're ffmpeg build includes open-ssl (so that it can download the video over https).

roberto68 · 2015-12-06T20:42:34Z

thanks JaySandhu, now it's workin right way :)

replace old downloaders with a unified ffmpeg downloader: - replace old HlsFD and RtspFD(based on mplayer and mpv) - add basic support for download range

angular-tools · 2016-02-25T08:06:04Z

I can give it a try to implement this feature.. Right now when I tried to skip the video, youtube sent a request shown below. I then tried downloading the link directly with wget and I also got a file of about 500 KB but it did not play in VLC, KMPlayer, MPlayer, etc. So maybe there is another missing piece?

@johnhawkinson apparently default windows cmd not support $

johnhawkinson · 2019-08-08T13:02:27Z

As I said, use bash. You're also not answering the question I asked, so it's going to be hard to help you.

Hrxn · 2019-08-08T16:37:06Z

Yeah, something like command1 $(sub-expression) flag1 is Bash-only, Windows CMD cannot do such a thing.

One of the many reasons why you should use PowerShell! Because it can do sub-expressions:

So try

ffmpeg -ss 3:59:10 -i $(youtube-dl -f 22 -g 'https://www.youtube.com/watch?v=mMZriSvaVP8') -t 3:06:40 -c copy react-spot.mp4

in PowerShell..

Edit:

Proof: 😄

PS C:\Move> mpv .\react-spot.mp4
Playing: .\react-spot.mp4

Also, since my storage is a bit short, this will download only the portion we need and not the entire 4hrs video to then trim and remove the rest, right? Appreciate any advice from you guys.

Download ffmpeg from https://ffmpeg.zeranoe.com/builds/
extrat it in a new folder and copy the path
example c:\ffmpeg

Replace from the original script "Download.bat"
replace %tools%\bin\ffmpeg.exe for ur path that contain c:\ffmpeg\bin\ffmpeg.exe

Now open a command line "cmd.exe"
In the folder where u saved download.bat
execute:
download.bat "https://www.youtube.com/watch?v=U8WRGFB_PWM" xx:xx yy:yy

xx:xx is start, yy:yy is the end

https://unix.stackexchange.com/a/550496/48971

I would like to try this, if possible, on an Android non-rooted device? I'm using Termux v0.8 with Python v3.7.5, Nano v4.5, and youtube-dl installed in it. With my very basic command line knowledge, what I tried doing is, I downloaded your *.sh file sitting alone to a new folder in my android device. Run Termux with the work directory where the *.sh file is located. Then executed the command "download_youtube.sh https://www.youtube.com/watch?v=U8WRGFB_PWM 00:10:00 00:15:00 intro.mp4" It returned me this line...

 download_youtube.sh: command not found

I thought I may need to install the *.sh file, so I did the "./download_youtube.sh" and returned me a message saying...

 bash: ./download_youtube.sh: Permission denied

I tried "chmod u+x download_youtube.sh" and it says...

 chmod: changing permissions of 'download_youtube.sh': Operation not permitted

I'm not sure what to do next. Can you help me what I did wrong?

Rodsevich · 2019-11-06T23:27:09Z

I know nothing about android and that you said there. But if it's like a normal Linux CLI environment you should check your permissions and where you are and that sort of things...
tell me the output of this:

users
whoami
ls -la .

Shintah07 · 2019-11-07T02:23:07Z

I got Termux from Playstore as Terminal for my Android device. The rest I installed through Termux via pgk, pip, & apt-get commands. I tried the commands you asked and it showed...

 $ users
 No command users found, did you mean:
  Command fuser in package psmisc

 $ whoami
 u0_a103

 $ ls -la
 total 21
 drwx------ 6 u0_a103 u0_a103 3488 Nov  6 15:03 .
 drwx------ 4 u0_a103 u0_a103 3488 Nov  6 13:02 ..
 drwx------ 4 u0_a103 u0_a103 3488 Nov  6 15:13 .cache

 drwx------ 2 u0_a103 u0_a103 3488 Nov  6 13:07 storage

I believe this has to do with my Android not being rooted. Idk. If so, we can't do much about it.

My apologies. I thought they're exactly the same as native Linux Terminal, guess not. I mainly work on desktop. I don't have nor tried Linux before but got interested of it out from your post, so thought of giving it a try. I remembered someone run Linux Terminal from Android so I did a little research and so came Termux and somehow I got those others installed as well. To make typing less painful, I installed Hacker's Keyboard from Playstore to emaulate the physical one. In short, curiosity just got me the desire to try.

@Shintah07 take a look at this: https://wiki.termux.com/wiki/FAQ#Why_do_I_keep_getting_.27permission_denied.27_when_trying_to_launch_a_script.3F

I did as you instructed and got it to work perfectly. It's awesome! I noticed, the downloaded file will be saved to the location where you are currently at in your Termux. Thanks Rodsevich!

Rodsevich · 2019-11-11T15:27:52Z

yeah, unless you put the path in the name. for example:
download_youtube.sh https://www.youtube.com/watch?v=U8WRGFB_PWM 00:10:00 00:15:00 ../intro.mp4 # will create intro.mp4 in the parent dir

download_youtube.sh https://www.youtube.com/watch?v=U8WRGFB_PWM 00:10:00 00:15:00 sorp/intro.mp4 # will create intro.mp4 in the sorp subdir of the current dir

When running the exact code from @Rodsevich in the previous comment (in terminal on macOS), I get this error:
date: illegal time format
usage: date [-jnRu] [-d dst] [-r seconds] [-t west] [-v[+|-]val[ymwdHMS]] ...
[-f fmt date | [[[mm]dd]HH]MM[[cc]yy][.ss]] [+format]

@miklide

Windows syntax
for /F "tokens=* delims=" %a in ('youtube-dl --get-url https://oload.stream/embed/Rp8UClDzOKk') do (ffmpeg -ss 00:26:33.091 -i %a -t 9.983 eam.mp4)
(You need phantomjs.exe on PATH to parse the OpenLoad URL in this example)

Much uglier, naturally 😝

Use %a when typing in the command prompt and %%a in batch files

⚠️ FFMPEG -to parameter is not supported here! If you use it ffmpeg will download sequentially until start time then process your fragment to end time and output your file. If your video is 2 hours long and you want to extract something from near the end you will download GBs of data only to throw it away. -t does work however, so subtract the start time from the end time to get the duration you need. More information: Seeking – FFmpeg

This solution works for me on Windows, in Anaconda prompt.
Just one small edit that when I paste the youtube url, it will be: for /F "tokens=* delims=" %a in ('youtube-dl --get-url "https://www.youtube.com/watch?v=--0NTAs-fA0"') do (ffmpeg -ss 3 -i %a -t 15 eam.mp4)

When I try this code in python, it doesn't work.
Could anyone find the problem on this code, thank you :)
command = ['for /F "tokens=* delims="', '%a',
'in', '(', 'youtube-dl', '--quiet', '--no-warnings', '--get-url', '"%s"' %(url_base + video_identifier),')',
'do', '(', 'ffmpeg', '-ss', str(start_time), '-i', '%a', '-t', str(end_time - start_time),
'-c:v', 'libx264', '-c:a', 'copy',
'-threads', '1',
'-loglevel', 'panic',
'%s' % output_filename,
')']
command = ' '.join(command)
try:
output = subprocess.check_output(command, shell=True,
stderr=subprocess.STDOUT)
except subprocess.CalledProcessError as err:
return status, err.output

UPDATED- It 's already SOLVED, thanks to the solution of es3.
The download.bat file:
@echo OFF
SETLOCAL
SetLocal EnableDelayedExpansion
set url=%1
set "cval=""
set cone=%url:~0,1%
if "%2"=="" (set start_time=) else (set start_time=-ss "%2")
if "%3"=="" (set duration=) else (set duration=-t "%3")
if not !cone!==!cval! goto MSG_INVALID_URL
for /F "delims=" %%i IN ('youtube-dl -f mp4 -e %url%') DO set "title=%4"
for /F "delims=" %%i IN ('youtube-dl -f mp4 -g %url%') DO set "get_url=%%i"
D:\Anaconda3\envs\myenv\bin\ffmpeg.exe -strict -2 %start_time% -i "%get_url%" %duration% "%title%"
goto END
:MSG_INVALID_URL
echo Invalid url, use double quote wrapped url
echo Example: "https://www.youtube.com/watch?v=xxxxxx"
goto END
:END
Then my python code will be like this: (download.bat "[youtube_url]" start_time duration output_file_directory)

Other solution could work well on cmd and python code: (updated from #622 (comment))
powershell.exe ffmpeg -ss 3 -i $(youtube-dl -f mp4 -g "https://www.youtube.com/watch?v=--0NTAs-fA0") -t 15 -c copy react-spot.mp4
Sample python code for autodownload from csv file:

The subprocess.check_output will run the command in Anaconda cmd (As I run this python code in Anaconda cmd) without a popup additional command window, as far as I know.

codewaseem · 2020-03-17T07:09:43Z

@roberto68 Sorry for the confusion, to get a direct link to the video you need to use youtube-dl's --get-url option. Then, with a direct video link from youtube-dl, you can use ffmpeg as described above.

Example:
youtube-dl -f 22 --get-url https://www.youtube.com/watch?v=mMZriSvaVP8

Then with the link:
ffmpeg -ss 14350 -i (link) -t 11200 -c:v copy -c:a copy react-spot.mp4

One line version:
ffmpeg -ss 14350 -i $(youtube-dl -f 22 --get-url https://www.youtube.com/watch?v=mMZriSvaVP8) -t 11200 -c:v copy -c:a copy react-spot.mp4

You can either pick a format with both video and audio (such as -f 22), or you can use ffmpeg to combine a DASH audio and video stream. You'll need to make sure you're ffmpeg build includes open-ssl (so that it can download the video over https).

Thanks!

In my case, I have to read such information like video_identifier, start_time, end_time in the csv file line by line, and download as well as trim the huge number of videos from youtube (such as Kinetics 400 dataset). Therefore a python code for automatically download just a portion of the video is needed for storage saving and also time-saving :)
Full code for that task could be such like the download.py I attached (I'm working on Windows 10)
download.txt

thanks for the quick reply
DUDE, thats PERFECT for what i need, i have text files full of ids and timestamps, some of which are from 3+ hours long podcasts. unfortunately i dont understand coding at all.
so far i changed download.txt to download.py, put it in to folder with csv file, downloaded anaconda3 and added it to environment variables. so few questions
1.
how should the csv file be named and formated? i could adapt it to your code.
video_id 1, output, start_time 1, end_time 1
video_id 1, output, start_time 2, end_time 2
video_id 2, output, start_time 1, end_time 1
pjJ2w1FX_Wg, C:\folder\name.mp4, 00:01:00, 00:01:30 for example?
2.
how do i run the python code? type download.py + path to the csv file in cmd?
thanks for your patience
