[Feature request] Add option to preserve all audio tracks.

[70sh1]

This would be nice.

[70sh1]

Apparently, replacing -map v:0? -map a:0? -map s:-1? part of the ffmpeg command with map 0 does the trick. Not tested with subtitles or multiple video tracks.

[70sh1]

local o = {
    include_all_tracks = false,
    ...
}

if o.include_all_tracks then
    cmds:arg("-map", "0")
else
    cmds:arg("-map", string.format("v:%s?", mp.get_property_number("current-tracks/video/id", 0) - 1))
    cmds:arg("-map", string.format("a:%s?", mp.get_property_number("current-tracks/audio/id", 0) - 1))
    cmds:arg("-map", string.format("s:%s?", mp.get_property_number("current-tracks/sub/id", 0) - 1))
end

Seems to work. Again, not tested with subtitles or multiple video tracks.

I'll refer to ffmpeg's doc later and implement this feature.
pr is welcome.

Can you try #19?
remember to set select_all_streams=yes in your config file

[70sh1]

Testing on a video without subs results in the following error:

[slicing_copy] stderr: Stream map 's' matches no streams.
[slicing_copy] To ignore this, add a trailing '?' to the map.
[slicing_copy] Failed to set value 's' for option 'map': Invalid argument

Following this suggestion seems to fix the issue:

--
if (o.select_all_streams) then
        cmds:arg("-map", "v?")
        cmds:arg("-map", "a?")
        cmds:arg("-map", "s?")
    else
--
