Remember to:

  • Ask your Python question, not if you can ask or if there's an expert who can help.
  • Show a code sample as text (rather than a screenshot) and the error message, if you've got one.
  • Explain what you expect to happen and what actually happens.

:warning: Do not pip install anything that isn't related to your question, especially if asked to over DMs.

@opal snow sorry, i'd suddenly become occupied!!

#

as far as i know, mutagen is metadata-only, at least for the id3 part

#

you can write tags but i don't know that you can get stuff like duration and other properties

#

excuse me while i look back at the old post to see what else i missed

opal snow
#

It happens, same here.

#

neat, i didn't know mp4 split their tracks up like that

#

in retrospect it makes more sense, but i always assumed mkv was more split up on account of the fact that you could softcode subtitles

#

okay, i think i get that!! let me do some fiddling and see what can be done

opal snow
#

It might explain if something got discarded - the tracks probably have to be the same type to overlay them. Distinct tracks is what lets you switch out eg different audio etc.

i suppose i need to acquaint myself with ffmpeg a bit more

cloud barn
opal snow
#

Yah. Do an ffprobe of some subtitled mp4 some time.

cloud barn
#

i've never seen that before, only .srt files that are put on top

#

if i find one, i will!!

#

weird, unless this is outdated, you have to use the hacky fix to add multiple inputs

#

yeah, i'm trying that out right now since i already have two ffmpeg.input() objects

#

i'm getting Could not find tag for codec h264 in stream #2, codec not currently supported in container though, i wonder if that's an os issue with some lacking dependency

opal snow

!paste
(Ignore this, trying to remember how to paste big things.)

Pasting large amounts of code

If your code is too long to fit in a codeblock in Discord, you can paste your code here:
https://paste.pythondiscord.com/

After pasting your code, save it by clicking the Paste! button in the bottom left, or by pressing CTRL + S. After doing that, you will be navigated to the new paste's page. Copy the URL and post it here so others can see it.

i keep docker on my server but this is just a small project

drifting thorn
cloud barn
#

it's just a mac laptop and i don't like fiddling with dependencies on it

#

huh, i haven't heard of that before

#

are there any codecs that would work for my use case ? i'll install orbstack if needed, but it'd be nice to avoid friction setting up the project

#

i'm looking into it and it looks like maybe not, especially since APIC MIME types can be multiple different image types, including png and jpg, so hardcoding a codec won't work

#

it's late for me though, so i'm going to call it here,, thank you all so much for your help!!

#

i'll definitely let you know when the final bits get put into place
