#H265

@3draven @akhil Спасибо, крутяк! 👍

Нашёл в #Telegram какого-то бота, написал запрос, он выдал.
Продублируют сюда, пусть останется, мож кто найдёт, тоже пригодится.

Скрипт для конвертирования видеофайлов (mp4|avi|mkv).

#!/bin/bash

# Укажите путь к папке с файлами для конвертирования
folder_path="/путь/к/папке"

# Переходим в папку с файлами
cd "$folder_path"

# Проходим по каждому файлу в папке
for file in *
do
# Проверяем, является ли файл видеофайлом
if [[ -f "$file" && "$file" =~ \.(mp4|avi|mkv)$ ]]
then
# Конвертируем файл с помощью ffmpeg
ffmpeg -i "$file" -c:v copy -c:a copy "${file%.*}.mp4"
echo "Конвертирован файл: $file"
fi
done

Я от себя поменял команду конвертации на

ffmpeg -i "$file" -c:v libx265 -vtag hvc1 -c:a copy "${file%.*}.mp4" — конвертация в .mp4 с кодеком h265

The compression ratio #h265 achieves in comparison with #h264 is impressive. Without setting up a scientific measurement, it would guess around 0.6 in file size.
But the encoding time required for that is just unholy. I never did much video editing or encoding, but the CPU time one can burn on that is insane.

@AIBot

Was ist #h265 ?

@susie I guess encoding in #AV1 (#VP9 + #Opus) isn't an option?

Cuz that should deliver #H265 - level #Efficiency and be on par with 24.000kbit/s #H264...

I'm testing a fantastic #fdroid application: #FFshare. It Converts / compress videos. It's excellent but it doesn't support #h265 (that is a pitty).

Just a test
Seems like #mastodon supports #h265 #video

@planettimmy @glassbottommeg #H265 / #AVC is contested by two #PatentPools (so it's not like with #H264 / #MPEG4 that you just pay #MPEG LA a fee)...

#AV1 (#VP9 + #Opus) & #WebM (#VP8 + #Vorbis) are the way to go...

I’m looking for someone experienced in ffmpeg/libavformat and web codes. I want to stream a frame buffer to a pubsub event bus which relays eventually the data as h264/h265 to a browser to show a video feed there. #ffmpeg #libavformat #h265 #h264

I wrote an article on how to quickly (13x speedup) convert an #H265 video to #VP8 using #FFmpeg and #Vaapi to upload it to #Mastodon respecting its restrictions 🎬

Thanks to Michael Kennedy @mkennedy , Samuel Colvin @samuelcolvin and Sebastián Ramírez Montaño @tiangolo for the interview they did at #PyConUS 2023 🇺🇸

Great article on why single frame comparisons are bad when comparing video quality, sometimes worse than bad metrics like VMAF.

#av1 #h265 #h264

Are there any good resources about how to render #videos optimized for the #web?

* What container formats and codecs are widely supported?
* What codecs should be preferred?
* Is #VP9 on #WebP better than #H264 in #MP4?
* Do we still need H264 for compatibility?
* Are there other codecs I should consider shipping? #AVIF? #H265? Do we ever need #GIF anymore?
* What tools can optimize these videos to shrink them as much as possible?
* Best practices for accessible videos? It feels weird that `alt` isn't a thing, but are captions supposed to address that?

I feel like I have a good sense of how to do images effectively after watching enough #HTTP203, but I'm less clear on effective video deployments.

I'm thinking: should I reencode a lot of old media into newer formats like #HEIF and #H265 in order to save disk space?

It will take some work and a lot of fiddling with settings but the worst of all is having to forever keep a dictionary of file hashes to look for duplicates.

Khronos Finalizes Vulkan Video Extensions for Accelerated H.264 and H.265 Decode

Vulkan Video extensions seamlessly integrate hardware accelerated video compression and decompression into the Vulkan API

Probando a subir video a #Pixelfed:

VÍDEO

He comprimido el video para poder subirlo, ha quedado bastante decente aun habiendo reducido el peso en un 85%, pero, ¿Me recomendarías algún compresor de video (online o software)?

I used to have a nice set of commands to create #H264 based videos at one point in time., but unfortunately it was removed for something else and git wasn't involved at that point in time.

Or have we come far enough yet that #H265 is an option?

If you were concerned about #Fedora losing some of the native graphics processing bits in mesa (#vaapi, #h264, #h265, #va1, etc.), #RPMFusion now has mesa-freeworld in testing to bring it back.

Encoding my #movies library in #h265 😛 my disk will thank me (but I have a 4k movie... it takes way too long to encode so I made it fhd, doesn't matter I don't use 4k displays anyway)
