#transcode — Public Fediverse posts

Was anyone aware that OBS now offers "Enhanced Broadcasting" aka Multritrack Video? This offloads video transcoding to the person that is streaming their content and off of the servers themselves.

This is the single biggest cost of hosting a livestreaming server. If users are willing to use what's in their system we can make the bar to entry incredibly low.

Just completed a #Transcode of around 30 minutes of .webm vid+aud into h.265 (aka #HEVC).

Took 8 hours.

And the computer's fan did a lot of whirring.

Getting a format that the TV wil play without #Transcoding seems necessary.

#H265 #WebM

TIL: #K3B kann DVDs rippen

nutzt dafür #transcode

was so seit 10(?) Jahren nicht mehr von irgendwem gepflegt wurde und daher in "keiner" distri mehr dabei ist

Yay!

Darf ich K3B also auch als totes Projekt ansehen?

I had hoped to add some #ffmpeg hardware acceleration on the #timelapses at @alberniweather using the old AMD RV730 card in #footiMac but I've not found the magic command to make it happy. I got close I think, but it seems to just refuse to connect to the video driver.

If there are any ffmpeg experts out there familiar with vaapi and old AMD graphics cards, I'd love to have a little help.

I created a reddit post in r/ffmpeg with all the details.

Has anyone tried #tdarr ? #video #transcode #transcoder #h264 #h265 #av1 #av1video

@RockyC
Ah, that makes a lot of sense. Have you looked at #Tdarr or #sickbeard_mp4_automator (not sickbeard or MP4 exclusive) that will automatically convert content when it's added?
#transcode

I could not find a working example for command line VLC to convert a WEBM video file to an MP3 audio file, so here you go:

vlc -I dummy INPUT_FILE.webm --no-sout-video --sout-transcode-samplerate 44100 --sout "#transcode{acodec=mp3,ab=128,channels=2}:std{access=file,mux=raw,dst=OUTPUT_FILE.mp3}" vlc://quit

https://codeberg.org/raster/gists/src/branch/main/VLC-macOS-CLI-Video-to-Audio

When you think about it it's pretty amazing we are carrying devices around that could at a pinch #transcode an hour of video live from #vlc on your phone to a TV that can't handle the codec without any discernable drain to the battery.

OK so for completeness, I remembered I had a script that captured a live stream and rendered it to file using cvlc, so I fucked around with that a bit and it works.

cvlc input.flac :sout="#transcode{acodec=mp3,ab=128,channels=2,samplerate=48000}:file{dst=output.mp3,no-overwrite}"

Also, I have no idea why I thought it was quicker, if anything it's fractionally slower than using a flac-lame pipeline or ffmpeg 🙄

Сегодня я узнал что vlc можно использовать так:
Пишем сие чудо
cvlc -vvv pulse://alsa_output.pci-0000_00_14.2.analog-stereo.monitor --sout '#transcode{acodec=mp3,ab=128,channels=2}:standard{access=http,ds
t=0.0.0.0:8888/pc.mp3}'

В терминал заменяя alsa_output.pci и тд на что нибудь из вывода pactl list |grep "Monitor Source", а потом заходим на localhost:8888/pc.mp3 например с телефона что бы не помереть от эха

Было бы конечно проще если бы работал нормально audio-share или я например знал как это сделать средствами чисто pipewire или pipewire-pulse, но это тоже очень классно

@SavahRellcast

How big was your file? More than 40MB?

There are ways to compress it down. I don't know what kind of computer you have, but there's a program available for #Linux, #Mac, and #Windows called #Handbrake that is supposed to be quite user-friendly. I haven't used it myself (I use some commandline tools that are ... difficult to get started with) but it has good word-of-mouth.

Downloads are here:

#transcode #codec #video

One of my hobbies is creating tools to #transcode my collection of Blu-ray Discs and DVDs for playback on #Plex servers. These are all cross-platform wrappers for #FFmpeg or #HandBrake. My most flexible script, focused on hardware video encoders, is here:

Feel free to message me if you have questions about my scripts, FFmpeg, #HandBrakeCLI, #MKVToolNix or other video nerdery. I've been doing this for over a decade so I can probably point you in the right direction.

Handbrake updated to v1.6.0. Now has AV1 video encoding.

Okay #fediverse I need a bit of #vlc #help - Trying to stream a mp4 into a RTP source. I can get it to connect, but the quality is horrible. using this "--sout "#standard{vcodec=h264,acodec=mp3,ab=128,channels=2,samplerate=44100}:std{access=rtmp,mux=ffmpeg{mux=flv}...." or "--sout '#transcode{vcodec=h264,vb=4000000,fps=30,scale=1,acodec=mp4a,ab=192,channels=2}:std{access=rtmp,mux=ffmpeg{mux=flv}...." both end up starting okay, then very quickly being unwatchable. Please boost!

This application also allows you to pull movies off from the physical DVD's you might still have on your shelf.

Many keep preferring physical media, by the way. Do you?

RAHH, 2h que je cherchais un moyen de faire un mp3 avec les 10 que j'ai à la suite.

vlc -vvv --sout '#transcode{vcodec=none,acodec=mp3,ab=128,channels=2,samplerate=44100}:file{dst=test.mp3}' --no-sout-all --sout-keep *.mp3

@kelbot I start the stream in a script at startup In a single line:
vlc --qt-start-minimized v4l2:///dev/video0:width=720:height=480 --sout '#transcode{vcodec=theo,acodec=mpga,vb=800, ab=128}:standard{access=http,mux=ogg,dst=:8080}'

Kalopsio worked on a small but powerful #script to #transcode your audio files before importing those into your #Funkwhale instance.
