well, the best way to deal with lossy compressed media is to… leave it as-is without recompressing. any time you're recompressing stuff you need to select between various tradeoffs depending on your specific circumstances :/

good morning. I have a question regarding the "deshake_opencl" filter, I need help to get it working in a gpu-only filter chain with vaapi decode/encode. I hope I've come to the right place

Greetings.
<cousin_luigi>
I would like to add two subtitles tracks to an existing mp4 file without reencoding anything. Handbrake doesn't seem to have such an option. How can I do it from command-like ffmpeg?
<cousin_luigi>
Also it would be nice to set descriptors for such tracks.
<furq>
you will have to reencode the subtitle streams because mp4 insists on its own weird text subtitle format
<furq>
i don't think you need sub_charenc but it'll be obvious if you do
<furq>
presumably -sub_charenc iso-8859-1 before that file's -i

Multiple -codec/-c/-acodec/-vcodec/-scodec/-dcodec options specified for stream 2, only the last option '-codec:s mov_text' will be used
<cousin_luigi>
Bah
<cousin_luigi>
No, the metadata thingie did not work
<cousin_luigi>
I can live without it
<furq>
that warning is fine
<cousin_luigi>
thanks
<furq>
-c copy applies to all streams and then -c:s copy overrides it
<furq>
-c:s mov_text
<galad>
cousin_luigi: if you are using a mac I made a little utility years ago to do just that https://subler.org
<galad>
webvtt and ttml can be muxed in mp4 too, however ffmpeg webvtt implementation is incomplete, and I don't know the state of ttml
<cousin_luigi>
galad: linux
<furq>
if you just want language metadata on the subs then -metadata:s:s:0 language=eng works here
<furq>
title doesn't seem to do anything in mpv
<cousin_luigi>
furq: Well, I wanted to mention the encoding.
<cousin_luigi>
Masquerading as language, I suppose.
<furq>
are they the same sub streams but encoded differently
<galad>
mov_text will convert everything to utf-16
<galad>
so unless there is something wrong with the input, there is no need to have different tracks
<galad>
or was it utf-8, I don't remember anymore what's used in tx3g, anyway, it doesn't matter
