Udemy-dl: Skip automatically generated subtiles

[ipkpjersi]

Hello,

I think it would be great if there was a way to skip automatically generated subtitles. This is a super necessary feature IMO and if you could find a way to do that, that would be amazing. I'm hoping that this should be simple enough to do since you already have the code for downloading and skipping subtitles.

Also, while I'm here, what happens if I have the resolution parameter set to 1080p but then a course only offers 720p, would it download the next highest resolution (so 720p)?

Great program, by the way!

@ipkpjersi thank you for the appreciation and using this program.

it already skips the automatically generated subtitles. when you set the resolution param to 1080p it will try to find that resolution if its not there it will show you a prompt asking that this quality is not available would you like to download the default one?. BTW you should set resolution param to 1080 instead 1080p which is already mention in README.
Example:

python udemy-dl.py -u [email protected] -p p4ssw0rd https://www.udemy.com/COURSE_NAME -r 1080

the other option is you set -d (default option) with -r (resolution option) which checks for the requested resolution and if its not there it will automatically download the default one and will not ask you that question again and again.

Example

python udemy-dl.py -u [email protected] -p p4ssw0rd https://www.udemy.com/COURSE_NAME -r 1080 -d

Hello,

In that case, it's a bug. When I downloaded from this course: https://www.udemy.com/webdevelopercourse/learn/v4/ that has automatically generated subs, it still downloaded the subs: https://i.imgur.com/2W59ocf.png

The command I used is: python3 ./udemy-dl.py https://www.udemy.com/webdevelopercourse/learn/v4/overview

Thank you for the information about resolution, that is good to know.

@ipkpjersi thanks i'll have a look and try to fix that as well. BTW is there any thing annoying about auto gen subs just asking, coz people wanna to download subs and you want to skip those caption.

[ipkpjersi]

Automatically generated subs are often very inaccurate for uncommon programming words/technologies and can be distracting so it would be nice to only have the manually generated subtitles which are known to be correct and skip the automatically generated subtitles.

[ipkpjersi]

Sorry for the double post but I am thinking that maybe if you are able to make it skip auto generated subs, perhaps you could make it as a flag/argument that way people who want auto generated subs can have them and people who don't can skip them.

[r0oth3x49]

@ipkpjersi i just checked the course with --skip-sub options it does not download the captions so this is not the bug. either i am not getting your point or you are not getting my point.

have i look i don't see any subs on this video although according to you it has auto gen subs.

there are two flags already available for subs.

• --sub-only which will download subtitles only.
• --skip-sub which will skip subtitles and download course lectures etc.

i will close this issue by tomorrow as invalid .

[ipkpjersi]

I don't feel it is invalid, I showed you my screenshot that has automatically generated subtitles downloaded by this program. Here is proof of the subtitles in-browser: https://i.imgur.com/TbarG0P.jpg

Here is proof that this program is downloading subtitles: https://i.imgur.com/nS9QUer.png

Try and see if you can replicate this functionality on Ubuntu 16.04 (in a virtual machine maybe), I am using Ubuntu 16.04. If you require any other information or can think of any other way I can help debug this, please feel free to let me know.

[ipkpjersi]

Sorry for the double post, but I just realized I am not explaining myself well. I want an enhancement to this program that skips ONLY automatically generated subtitles (because they are usually very inaccurate), while still downloading manual subtitles (which are usually perfect). I am not sure if this is even possible.

You can see in my in-browser screenshot that instead of it saying "English" it says "English [Auto]".

[r0oth3x49]

@ipkpjersi i got your point & tested on Ubuntu a latest available version with a simple command, here is a simple way you can skip subs (either it is auto gen or created by author or course). there is no special way available right.

python3 udemy-dl.py -u USER -p PASS COURSE_URL --skip-subs

again i'll say this not the bug this is invalid. the screen shot you showed is downloading because you didn't set flag --skip-sub that's why it is downloading.

[ipkpjersi]

I'm not quite sure you are getting my point. My point is I would like to skip automatically generated subs whilst downloading manually created subs without having to specify individual courses to skip subs or not, but instead have a "--skip-automatic-subs" that checks if the subs are automatically generated and if so skips them for that course, otherwise it downloads them as they must have been manually created. I don't want to skip all subs, just automatically generated subs.

By default, this program does not skip automatically generated subs and download only manually created subs, this program simply downloads all subs regardless of whether they are automatically generated or not. Skipping subs skips both automatically generated and manually created subs. Is what I want not possible? It would certainly be a nice enhancement. If it is not possible then certainly this issue should be closed. Thanks.

[r0oth3x49]

@ipkpjersi i got your point and also checked some courses having auto-gen subs but either of these courses have auto gen subs or custom created subs i cannot find both in a single course. find me a course which has both auto gen subs & author's created subs so i can test the utility properly otherwise i will consider this option as future update.

[ipkpjersi]

Hello,

Yeah it's not possible for a course to have both automatically generated and manually created subs since automatically generated subs are only created if an author has not manually created subs. I wasn't sure if it's possible to check if subtitles are automatically created or manually generated.

Thanks.

[r0oth3x49]

@ipkpjersi always welcome and thanks for using this utility. now i assume you are clear about subtitles and also satisfied with the available options for skipping/downloading subs as you said it is not possible for a course to have both auto subs & custom one as well.

• Skip captions

python3 ./udemy-dl.py https://www.udemy.com/webdevelopercourse/learn/v4/overview --skip-sub

• Download captions only

python3 ./udemy-dl.py https://www.udemy.com/webdevelopercourse/learn/v4/overview --sub-only

if you still have any suggestions do suggest i will consider that as future enhancement.

[ipkpjersi]

Yeah I would still like the ability to skip only automatically generated subs while still downloading manually created subs (without having to check on a course-by-course basis, but having this program check automatically). I think that would be a good future enhancement.

[r0oth3x49]

@ipkpjersi okay i 'm considering this as future enhancement and also will wait for other to suggest the same. now i 'm closing this issue as future enhancement. BTW this is nothing but just another check on subs.
