От командной строки FFmpeg к Rust: практическое руководство для различных сценариев

FFmpeg — это мощный инструмент для работы с мультимедиа, который широко используется для редактирования видео, конвертации форматов и других задач. Однако использование командной строки FFmpeg (CLI) напрямую может быть связано с определёнными сложностями:

Три минуты на освоение обработки аудио и видео | Элегантное использование FFmpeg в Rust

Обработка аудио и видео может показаться сложной задачей, но в разработке нам рано или поздно приходится сталкиваться с такими задачами, как конвертация форматов видео, обрезка, добавление водяных знаков или извлечение аудио. FFmpeg — это признанный стандарт в индустрии, который умеет почти всё. Его используют популярные программы, такие как VLC, YouTube и OBS. Однако у FFmpeg есть свои подводные камни, которые могут доставить разработчикам головную боль: https://github.com/YeautyYE/ez-ffmpeg

Pretty late, but comment to the #Snap and #Flatpak episodes:

My Flatpaks take up 30GB of space, after deduplication. A ton of outdated runtimes (badly maintained packages) and random stuff like #mpv or #ffmpeg shipped with apps instead of as a runtime extension are issues.

And no, you dont need to have an entire #distribution for #sandboxing. You can use #bubblejail and other new tools like #crabjail or #fortify.

For Flatpak and Snap, cross compatibility is 1st priority

#ffmpeg is powerful, but sometimes I think it is harder to operate than my #kubernetes cluster lol

I made a video and an audio track sound. I synchronized the two with ffmpeg. They are well in sync on my (linux) and on a friend's (mac) laptop.

But when I load and read it on my (android) phone, the audio is slightly (.1-.2 sec?) but visibly out of sync. I can't upload this on Loops. Annoying. Any one has an idea of what I can do?

I'm having lots of fun researching about #HLS, as I develop a video platform as a side quest and try to keep things on a budget, my plan is to have #nginx proxying to #minio but using subrequest auth to serve the streams. Will use #ffmpeg to encode the videos for adaptive streaming and encryption. I think everything I have cooking in my head should work, now down to implement the missing parts before gluing everything together. Oh, and I'm thinking on hosting on an OVH dedicated server.

Here is the new #Development #PC Build:

- #AMD #Ryzen 7 7700X
- #Gigabyte B650 Gaming X AX V2
- #GSkill 32GB DDR5 PC-6000
- #Samsung 990 Evo Plus 1TB
- #Thermalright Peerless Assassin 120 SE
- #LianLi Lancool 2007 Case
- #MSI MAG A750BE PSU
- @kde Neon

Went w/ integrated graphics for the time being & it is more than I need. Does #3dprinting slicing & drawing just fine, #virtualization just fine, #ffmpeg & the little bit of video editing I do. Blows the old i7-6700 w/ 16GB out of the water!

#PeerTube - Importation #YouTube, #transcodage #HLS avec support #P2P en 720p/1080p MP4/AAC, création des vignettes, le tout grâce à #FFMPEG
Après On supprime YouTube
Mais avant, il y a encore toutes les vidéos sur #Emmabuntus et la clé magique

So TIL @ScottManleyHimself developed for #LAME for #FFMPEG. #MP3 #mp3codec

I always find that TikTok downloadable videos have a great size to quality ratio. With dark magic, a friend figured out what #ffmpeg options they use. Here you go:

ffmpeg -i input.mp4 \
-vf "scale=576:1024:flags=lanczos" \
-c:v libx264 -profile:v high -level 3.1 -preset slow \
-b:v 385k -maxrate 420k -bufsize 800k \
-c:a aac -b:a 37k -ac 2 -ar 44100 \
-movflags +faststart \
output_tiktok_style.mp4

I still can't make mpv work again...

I don't know if it is still broken for everyone or if I have broken it even more...

I dropped the old version of libtheora as suggested and messed around with the symlinks and I don't know how to get it back to "normal".

(I use multilib, alienbob and kde6 repos)

I currently have this mess in /lib64:

I did this amazing recording of a tree swaying in the wind and knocking at another tree the other day for my upcoming mini exhibition at Notam. It was recorded by sticking a Geofin in between the roots to get the sound of the wind from the perspective of the tree.

I will resynthesize this as a vibrator motor signal for the exhibition too. Pretty excited!

MTS files are a common container format for high-definition video, often used by HD camcorders, and can be played with various media players like VLC, or converted to other formats like MP4 using Handbrake or FFmpeg. Video editors like Kdenlive, Flowblade and Shortcut also support editing MTS files.
