Hi Sagnac,

I installed streamsave on my Debian 10 Buster Box. My expectation: dump to my disk the stream I am watching.

mpv 0.29.1 Copyright © 2000-2018 mpv/MPlayer/mplayer2 projects
built on UNKNOWN
ffmpeg library versions:
libavutil 56.14.100 (runtime 56.22.100)

ffmpeg version: 4.1.6-1~deb10u1

I have installed:
lua script on: ~/.config/mpv/scripts/streamsave.lua
no config file on: ~/.config/mpv/scripts/script-opts

Steps to reproduce.

Note: I already installed ano

I have A Playlist.me3 PLAYLIST FILE with URL to internet for streamed videos.

url are streamed and played with mpv, no problems

With this command:
mpv --idle=once --load-scripts=yes iptvPlaylist.m3u

I got these error messages after typing CTRL-Z :

`[streamsave] Command 'expand-path' not found.
Playing: iptvPlaylist.m3u

Thanks in advance for your help reviewing this.

Thanks for streamsave lua script.

Hi, thanks for the information.

I see you're using an old version of mpv (v0.29.1) while the expand-path command which the script uses was added in v0.30.0 so updating to the latest version of mpv should fix this issue.

Thanks Sagnac.

I uninstalled mpv from Debian buster. There is no a more recent mpv version from debian backports, so I had to install from git, following this guide:

https://github.com/mpv-player/mpv-build#instructions-for-debian-and-ubuntu

After, some time I finally could install mpv from source.

mpv 0.33.0-329-g8aef22e45d Copyright © 2000-2020 mpv/MPlayer/mplayer2 projects built on Thu Sep 2 18:29:43 EST 2021 FFmpeg library versions: libavutil 57.4.101 libavcodec 59.7.100 libavformat 59.5.100 libswscale 6.0.100 libavfilter 8.7.100 libswresample 4.0.100 FFmpeg version: N-103481-g646afae00f

BUT:

I got this messages while trying to load your lua script.

Can't load unknown script: /home/XXX/.config/mpv/scripts/streamsave.lua

Googling some time I found this was caused by a lua 5.3 version I had installed. Seems a problematic version for mpv scritps and is avoided by mpv. Therefore my mpv build has NO OSM interface and no lua supported.

So I uninstalled lua 5.3 and installed lua 5.2
lua -v Lua 5.2.4 Copyright (C) 1994-2015 Lua.org, PUC-Rio

To recompile mpv I added this to mpv_options config file for compilation

--enable-ffmpeg-strict-abi
--enable-lua
--lua=52

But I get this error when compilation script verifies lua:
Checking for Lua : no ('lua >= 5.2.0 lua < 5.3.0' not found) You manually enabled the feature 'lua', but the autodetection check failed.

Tried the same with another alternative: luajit, but is not detected.

I have both installed:

lua -v Lua 5.2.4 Copyright (C) 1994-2015 Lua.org, PUC-Rio

luajit LuaJIT 2.1.0-beta3 -- Copyright (C) 2005-2017 Mike Pall. http://luajit.org/ JIT: ON SSE2 SSE3 SSE4.1 fold cse dce fwd dse narrow loop abc sink fuse

and these are my installed packages:

`dpkg -l|grep lua

ii luajit 2.1.0~beta3+dfsg-5.1 amd64 Just in time compiler for Lua programming language version 5.1`

I am stuck at this point. Is there any missing lua package dependency?

Thanks in advance for reviewing this issue.

Francisco.

Sorry for the late response. If you're still experiencing difficulty running a newer version of mpv what you can do is edit Line 148 in the script so that the expand-path command is not used.

Specifically, that line should look like this:

file.path = opts.save_directory

Note that you won't be able to specify your preferred directory using mpv style double tilde paths without expand-path.
