The only caveat of the #Whisper project is that it only works on 16-bit #WAV files.

There is a #FFMPEG script on how to do it via the #terminal

ffmpeg -i input.mp3 -ar 16000 -ac 1 -c:a pcm_s16le output.wav

#DailyBloggingChallenge (364/365)

The ‘Quick Start’ section in the Readme sufficed for setting up.

The only thing that I had to change in the ./models/download-ggml-model.sh script (1) is remove the option --show-progress on line 105. Seems like GNU Wget2 2.1.0 doesn’t have that option.

Alternatively one can replace the option with

--progress=bar --force-progress

Instead opted in to using #Whisper which also works with #KdenLive.

Although Whisper is originally written in #Python there is a #CPP project that makes transcribing very fast. It took less than 2min to transcribe the 26 min audio clip.

Originally wanted to use #VOSK to transcribe the #SpeechToText. Initially tried it out over #KdenLive and its ‘Speech Recognition’ tool.

This took quite awhile to setup, since it is not concrete what kind file format, if any, the VOSK model should have. Additionally, the recommendation of setting up a virtual #Python environment didn’t work as expect and went with the global approach.

And finally scratched the whole approach, once realizing that transcribing 26 min audio clip is taking longer than 10min.

#DailyBloggingChallenge (361/365)

Further options exist like #YouTubeDL (1) or stream via #VLC.

Sometimes I wished that creators would mirror their channels on more permissive sites like #PeerTube or #Odysee that don’t hard-lock into watching ads.

Alternatively one could also use #FFMPEG to combine the files together via the #Terminal like

ffmpeg -i video.mp4 -i audio.wav -c:v copy -c:a aac output.mp4

Most of the time, I try to watch videos on #Invidious with lower resolution to speed up loading time, especially since I watch by default at twice the playback rate.

Today I realized that some instances permit the downloading of content. And even if one has to download audio and video separate, one can easily merge them together temporarily in one’s favorite #VideoEditor without the need to render the end product.

This concludes the explanation behind the process of creating a #Paypal partial for #Hugo using #GoLang tricks combined with #HTML, #CSS, and #JavaScript

The #TLDR can be read at https://bf5.eu/post/guide/hugo-how-to-create-paypal-partial/

#DailyBloggingChallenge (356/365)

Now one shall add the missing checks and default cases. Further one shall add the CSS classes mentioned in 353.

The result is seen in the image.

#DailyBloggingChallenge (355/365)

Now that the partial is complete, look back at its parent. Combining the code from 345 and 348 one gets this image.

The problem of this code so far is that it doesn’t check if the $itemsOutput exists. Further there are no checks that the array .Params.paypalItems has any items and there is no default case.

• 348: https://qoto.org/@barefootstache/112915551078887830

#DailyBloggingChallenge (354/365)

The whole code of the partial looks like in the image.

A lot of this code can be squashed to save space for the cost of readability.

#DailyBloggingChallenge (353/365)

Looking at the #JavaScript code in the image that will be parsed over #GoLang using the printf function.

First one creates a change event listener function that is bound to the id of item-select-$uniqueID. The <select>-tag shall be added the id attribute in line 13 (351).

Additionally a custom attribute data-image shall be created and placed on the <option>-tag in line 15 (351). This holds the path to the image value within the paypalItems element.

Outside of the partial the #CSS classes selected-value and selected-image need to be defined. They present the respective values from paypalItems element.

In the initial case, lines 10-11 will be called that take the value from the first element in the paypalItems array. Defined from {{ $selectedValue := index .items 0 }} which shall be prepended before the JavaScript code.

• 351: https://qoto.org/@barefootstache/112915802181947117

#DailyBloggingChallenge (352/365)

This code will generate dynamically based off of the length of the paypalItem or .items variable and use the first element of it as the default value (line 9).

Next one will extend the code with more CSS classes to ease the referencing of the JavaScript actions.

#DailyBloggingChallenge (351/365)

Now that the #PseudoCode exists, it shall be converted into #Hugo syntax as described in 349. As in the image, some #GoLang functions are used like printf and other Hugo functions to loop over the variables that are saved as an array type.

• 349: https://qoto.org/@barefootstache/112915585198772399

#DailyBloggingChallenge (350/365)

Now wrap the #HTML code (338) with a <div> and a #CSS class that extends the uniqueID (345) in its name. The pseudo code looks like the image.

• 345: https://qoto.org/@barefootstache/112786991862960301

#DailyBloggingChallenge (349/365)

Further within the partial, since safeHTML will be used one can parse string using #HTML and #JavaScript syntax within #GoLang. As an example

{{ $output := "" }}

{{ $output = print $output "<span>Example</span>" }}

{{ return $output }}

This creates a <span>-tag with the text Example after safeHTML pipe is applied.

#DailyBloggingChallenge (348/365)

In 342 the first mention of using a callback function is used without any concrete description of how it shall be built. From the last image one needs to change the partial reference to be saved as a variable which is then piped with safeHTML, so

{{ $itemsOutput := partial "paypal-button" (dict "paypal" .Params.paypal "items" .Params.paypalItems "headName" .Params.paypalHeadName "headValue" .Params.paypalHeadValue "uniqueID" $uniqueID) }}

and the rendering is done via

{{ $itemsOutput | safeHTML }}
