Linux mentioned, but not possible to get working?

[spacelama]

There's several mentions on Linux/ubuntu etc in eg README.md, but judging from requirements.txt, this is never going to work with the dependency on pywin32 and inherent dependencies on things such as mpv-2.dll. Looking at git log/git blame, it looks like linux has been an afterthought since well before 4420ee3 and maybe all the way back to v2.1.4 (which I couldn't get pip3 install -r requirements.txt to run anyway).

If it's no longer a consideration, maybe that should be clarified in README.md.

[dfaker]

The win32 module is only used for supporting long and network hosted files on Windows, and the import is skipped on other platforms.

And yes on Linux it's the .so version of the library not the .dll, support for either us handled by pythonmpv.

Looks like removing the win32 line from the requirements.txt should get it all installing for you. I'll see about adding in a Linux specific requirements.txt

[spacelama]

OK, I had further problems when I tried that originally, but didn't realise most of the python stack dumps were from code paths that were try/excepted. Still unable to test probably because of my libmpv version (libmpv1) - I can't test that until I'm in a position to update my workstation from debian oldstable. (install instructions for linux could probably do with a note to ensure apt install libmpv2 or equivalent if available)

[LeKite]

Is it still not possible to run this on Linux? I recently put Manjaro and I'd love to have this on it. I really like the tool.

[dfaker]

@LeKite I've added a requirements-linux.txt now skipping the win32 dependency, that along with libmpv2 should be all you need, give it a go and if you get any failures we'll see what additional guidance we need to add to a linux install note.

[LeKite]

Mmm im very stupid to know how to make it run though. An AUR package would be awesome

Haven't used this program in a while but I cloned it today and i'm unable to get it to work. Using arch linux.

@broconut123 hey buddy I saw you're using Arch.. would you help me make this run? ;w;

Sure. Install tk and possibly mpv with aur helper yay or paru

paru -S tk mpv

cd into the webmgenerator folder

make a virtual environment https://wiki.archlinux.org/title/Python/Virtual_environment python -m venv envname then activate environment with source envname/bin/activate then pip install -r requirements-linux.txt then run it with python webmGenerator.py

I have to add, I made webms previously with this method on Arch...

[dfaker]

@LeKite not really enough to go on there apart from ffmpeg is failing to produce a file.

"previously with this method" could mean anything!

Is this for all encode types? (mp4 and VP8 webm too for example), do you have any filters applied?

What ffmpeg version do you have installed?

Sorry. To clarify. This method means on arch with the installation provided from the other user.. anyway no filters. Happens with mp4 rendering and vp9 webm at least. I can try more and give you any info you ask me

[dfaker]

Does seem like the ffmpeg version mismatch in that case, please run a ffmpeg -version and confirm what you're running.

All seems correct, try running those Ffmpeg commands it's printing into the console in the same wording dir as WmG and see what the internal failure in ffmpeg is.

You'll need to get the console output from a running instance of WmG and make sure to keep WmG open so it doesn't delete the temporary files.

in that case the question is why isn't the prior command producing an output file.

in that case the question is why isn't the prior command producing an output file.

... do I do the same thing as you previously explained?

[Mojavve]

I'm running into the same FileNotFoundError: [Errno 2] No such file or directory issue. The encode gets stuck at 75% and the errors are the same ( [Thread-6 (en] [ERROR] unhandled CONCAT exception and then the no such file error) ffmpeg version n7.0.1 Arch Linux I've encoded hundreds of vp9 webms using WmG previously on the same setup. cloned the repo today

Trying to encode an h.264 mp4 with the filename test.mp4 to vp9 webm.

At the time of the error, my tempVideoFiles folder has filters_1.txt along with 0_testmp4_0.0_1.0010000000000001_c0a5150cb0_1722805269_0.mp4 but no log file despite it claiming it finished pass 1.

Trying to run the ffmpeg commands given

ffmpeg -y -i tempVideoFiles/0_testmp4_0.0_1.0010000000000001_c0a5150cb0_1722805269_0.mp4 -filter_complex_script tempVideoFiles/filters_1.txt -map [outvfinal] -pass 1 -passlogfile tempVideoFiles/encoder_1.log -shortest -copyts -start_at_zero -c:v libvpx-vp9 -c:a libopus -stats -pix_fmt yuv420p -threads 4 -auto-alt-ref 6 -lag-in-frames 25 -quality good -psnr -row-mt 1 -tile-columns 1 -tile-rows 0 -arnr-maxframes 7 -arnr-strength 5 -aq-mode 0 -tune-content film -enable-tpl 1 -frame-parallel 0 -metadata Title=test WmG -b:v 6144000.0 -an -sn -f null /dev/null

I get zsh: no matches found: [outvfinal] Assuming this is just a formatting error with my shell I put it in quotations. Next I get Unrecognized option 'psnr'. if I remove the psnr flag I get [AVFormatContext @ 0x63c31e0e5900] Unable to choose an output format for 'WmG'; use a standard extension for the filename or specify the format manually. [out#0 @ 0x63c31e0a5b00] Error initializing the muxer for WmG: Invalid argument Error opening output file WmG. Error opening output files: Invalid argument I assume this is also just a weird formatting error with the title metadata and my shell so I put that in quotations.

After that, it did work. It created a log, and I then continued to run the 2nd pass command after fixing it up in the same way (adding quotations, removing -psnr):

ffmpeg -y -i tempVideoFiles/0_testmp4_0.0_1.0010000000000001_c0a5150cb0_1722805269_0.mp4 -filter_complex_script tempVideoFiles/filters_1.txt -map "[outvfinal]" -pass 2 -passlogfile tempVideoFiles/encoder_1.log -shortest -copyts -start_at_zero -c:v libvpx-vp9 -c:a libopus -stats -pix_fmt yuv420p -threads 4 -auto-alt-ref 6 -lag-in-frames 25 -speed 1 -quality good -row-mt 1 -tile-columns 1 -tile-rows 0 -arnr-maxframes 7 -arnr-strength 5 -aq-mode 0 -tune-content film -enable-tpl 1 -frame-parallel 0 -metadata Title="test WmG" -b:v 6144000.0 -an -sn tempVideoFiles/test_1.webm

and it worked as well although the output webm was extremely low bitrate for whatever reason. I'm not super familiar with what the PSNR option is supposed to do so maybe the quality is related to removing that?

I know most of this was me adjusting for zsh but I wanted to thoroughly explain all of my steps. psnr being an unrecognized option seemed to be the only real roadblock.

If there's anything else I can supply let me know.

@Mojavve very helpful I saw that was being deprecated but isn't yet gone on my version, will toggle that to the new option.

I'm running into the same FileNotFoundError: [Errno 2] No such file or directory issue. The encode gets stuck at 75% and the errors are the same ( [Thread-6 (en] [ERROR] unhandled CONCAT exception and then the no such file error) ffmpeg version n7.0.1 Arch Linux I've encoded hundreds of vp9 webms using WmG previously on the same setup. cloned the repo today

Trying to encode an h.264 mp4 with the filename test.mp4 to vp9 webm.

At the time of the error, my tempVideoFiles folder has filters_1.txt along with 0_testmp4_0.0_1.0010000000000001_c0a5150cb0_1722805269_0.mp4 but no log file despite it claiming it finished pass 1.

Trying to run the ffmpeg commands given

ffmpeg -y -i tempVideoFiles/0_testmp4_0.0_1.0010000000000001_c0a5150cb0_1722805269_0.mp4 -filter_complex_script tempVideoFiles/filters_1.txt -map [outvfinal] -pass 1 -passlogfile tempVideoFiles/encoder_1.log -shortest -copyts -start_at_zero -c:v libvpx-vp9 -c:a libopus -stats -pix_fmt yuv420p -threads 4 -auto-alt-ref 6 -lag-in-frames 25 -quality good -psnr -row-mt 1 -tile-columns 1 -tile-rows 0 -arnr-maxframes 7 -arnr-strength 5 -aq-mode 0 -tune-content film -enable-tpl 1 -frame-parallel 0 -metadata Title=test WmG -b:v 6144000.0 -an -sn -f null /dev/null

I get zsh: no matches found: [outvfinal] Assuming this is just a formatting error with my shell I put it in quotations. Next I get Unrecognized option 'psnr'. if I remove the psnr flag I get [AVFormatContext @ 0x63c31e0e5900] Unable to choose an output format for 'WmG'; use a standard extension for the filename or specify the format manually. [out#0 @ 0x63c31e0a5b00] Error initializing the muxer for WmG: Invalid argument Error opening output file WmG. Error opening output files: Invalid argument I assume this is also just a weird formatting error with the title metadata and my shell so I put that in quotations.

After that, it did work. It created a log, and I then continued to run the 2nd pass command after fixing it up in the same way (adding quotations, removing -psnr):

ffmpeg -y -i tempVideoFiles/0_testmp4_0.0_1.0010000000000001_c0a5150cb0_1722805269_0.mp4 -filter_complex_script tempVideoFiles/filters_1.txt -map "[outvfinal]" -pass 2 -passlogfile tempVideoFiles/encoder_1.log -shortest -copyts -start_at_zero -c:v libvpx-vp9 -c:a libopus -stats -pix_fmt yuv420p -threads 4 -auto-alt-ref 6 -lag-in-frames 25 -speed 1 -quality good -row-mt 1 -tile-columns 1 -tile-rows 0 -arnr-maxframes 7 -arnr-strength 5 -aq-mode 0 -tune-content film -enable-tpl 1 -frame-parallel 0 -metadata Title="test WmG" -b:v 6144000.0 -an -sn tempVideoFiles/test_1.webm

and it worked as well although the output webm was extremely low bitrate for whatever reason. I'm not super familiar with what the PSNR option is supposed to do so maybe the quality is related to removing that?

I know most of this was me adjusting for zsh but I wanted to thoroughly explain all of my steps. psnr being an unrecognized option seemed to be the only real roadblock.

If there's anything else I can supply let me know.

Now that you mention it. I may have swapped from bash to zsh and the error started occurring.

[dfaker]

PSNR flag changed in master now.

[LeKite]

PSNR flag changed in master now.

I can confirm it worked, but the result is very bad.

This is a 30second clip, webm VP9 with audio. rez is 720p. Is this normal behavior?

[LeKite]

Another 16 second clip from instagram

[dfaker]

Yep that definitely seems worse than expected, I'll need to bisect the ffmpeg versions.

[dfaker]

seemingly an ffmpeg 2-pass regression

[dfaker]

@LeKite okay that seems a lot prettier try a fresh pull.

[LeKite]

Hello, I just did a fresh pull and tried again... Not very different..

[dfaker]

@LeKite Very strange, this is master and ffmpeg version 2024-08-01-git-bcf08c1171 encoding https://www.youtube.com/watch?v=aqz-KE-bpKQ as 20 second 4MB VP9 10BPP webm, timestamps 00:60-00:80

and the standard depth 4MB VP9:

Can you confirm your ffmpeg -version and post the output of ffprobe outputfile.webm?

Also I pulled again the project and tried again, but still super grainy. Also for the yt-dlp I have updated it via the GUI, and my system is up to date.

[dfaker]

ffprobe outputfile.webm on any of your 'grainy' files will be fine.

[LeKite]

yeah I posted it previously

Just wanted to chip in. Did a fresh clone, made a new venv and did the pip install and I just made a VP9 webm without issues.

Mmm, maybe I need to make a new venv? I never done that for previous releases but I will try.

@LeKite

Another one: [beki@arch finalVideos]$ ffprobe dreamymoo_1.webm ...

That's consistent with the prior commit not the current state of master, please share the tempVideoFiles/filters_*.txt it's attempting to use.

[LeKite]

I can confirm, creating again the env, and reinstalling requisites made it work properly. I didn't think it was needed. Previously I just overwrote the files with the new ones. This is what I always used to do in Windows.. works now. Thanks everyone.

[dfaker]

@LeKite great news! I think something went wrong with your pull there as that shouldn't actually be needed.

Closing this thread now, as it's become a grab-bag of Linux issues, if any further problems arise please raise a separate issue.
