Edit: I don't know why but specifying the filename of the script-opts file made it work even though the basenames are the same.

Change:

From:

-- Define a table with default options local o = { memory_usage_percentage = 80, reserved_memory_gb = 6 }

-- Read the options from the script-opts file options.read_options(o)

-- Print the read options for debugging purposes msg.info("memory_usage_percentage: " .. o.memory_usage_percentage) msg.info("reserved_memory_gb: " .. o.reserved_memory_gb)

To:

-- Define a table with default options local opts = { memory_usage_percentage = 80, reserved_memory_gb = 6 }

-- Read the options from the script-opts file (require 'mp.options').read_options(opts, "demuxer-max-bytes")

-- Print the read options for debugging purposes msg.info("memory_usage_percentage: " .. opts.memory_usage_percentage) msg.info("reserved_memory_gb: " .. opts.reserved_memory_gb)

Original post: I am making a lua script to adjust buffer size dynamically based on available ram. The script is working with the hardcoded values: memory_usage_percentage = 80, reserved_memory_gb = 6 but it is not reading the new values from my script-opts file. Do you see why?

cat /home/cmysmiaczxotoy/.config/mpv/script-opts/demuxer-max-bytes.conf

memory_usage_percentage=70 reserved_memory_gb=8

cat /home/cmysmiaczxotoy/.config/mpv/scripts/demuxer-max-bytes.lua (Now edited with fix)

-- Require the necessary modules local mp = require 'mp' local msg = require 'mp.msg'

-- Define a table with default options local opts = { memory_usage_percentage = 80, reserved_memory_gb = 6 }

-- Read the options from the script-opts file (require 'mp.options').read_options(opts, "demuxer-max-bytes")

-- Print the read options for debugging purposes msg.info("memory_usage_percentage: " .. opts.memory_usage_percentage) msg.info("reserved_memory_gb: " .. opts.reserved_memory_gb)

local function is_windows() return package.config:sub(1,1) == '\\' end

local function set_memory_properties(free_mem_kib, total_mem_kib) -- Calculate the percentage of the total memory in KiB local allowed_mem_kib = total_mem_kib * (opts.memory_usage_percentage / 100) -- Convert reserved memory from GB to KiB local reserved_mem_kib = opts.reserved_memory_gb * 1024 * 1024 -- Calculate the amount of memory to use, leaving the reserved memory free local mem_to_use_kib = allowed_mem_kib - (total_mem_kib - free_mem_kib - reserved_mem_kib)

-- Convert to bytes and round to nearest integer local mem_to_use_bytes = math.floor(mem_to_use_kib * 1024)

radion is an internet radio CLI client, written in Bash.

https://gitlab.com/christosangel/radion

Radion can be costumized as far as the station selecting program is concerned. The user can choose between:

• read

!read

• fzf

!fzf

• rofi

!rofi

• dmenu

!dmenu

---

Update: Introduced new feature: costumizing prompt text for fzf dmenu and rofi.

--- Update: Recording functionality added, with the use of another (you guessed it) bash script

!icy

Also options in read as Preferred selector are also case insensitive.

Any feedback is appreciated!
