A Transcoding DLNA Server

Rustymedia

Rustymedia is a media server. It mimics the DLNA protocol and should work with most DLNA clients.

Usage

# Serve two directories.
cargo run -- --local 'My Videos'=~/Videos --local 'Other Stuff'=/mnt/usb/vids

# See all options.
cargo run -- --help

Transcoding

The server automatically transcodes to formats that the client supports (if required). Right now only a couple of clients are recognized. Other clients get a "safe" profile which is likely to work.

Recent transcodes are cached as anonymous files in /tmp, kill the server to clear the cache.

rustymedia's Issues

Panic on socket connect on MacOS Mojave

Panics at socket.connect("239.255.255.250:1900").unwrap(); in src/dlna/discovery.rs.

Randomize server UUID by default.

It would be good to set it by hash(machine-id, ip, port) or something similar

Cannot build on MacOS

MacOS 10.14.1

I suspect may be an issue I need to raise at https://github.com/meh/rust-ffmpeg instead, but just putting it out there.

I was hoping to work on #4 as my first Rust contribution (thanks for the label), but obviously won't get far if I can't build as is!

Detect Device Type

It would be good to detect the device type and transcode appropriately. It would also be nice to default to no transcoding if we don't know about the device, or maybe try to pick a "safe" or "common" set but that will probably never work.

Path is not expanded

When using ~ as in the example --local 'My Videos'=~/Videos no content is listed.
Absolute path works.

Limit Cache Size

Right now it is unlimited (until the server restarts). It would be good to have a cap.

Ideas:

• Limit by disk space.
• Limit by disk space available.
• Limit by number of entries.
• Purge cheaper transcodes first (audio/container only).

Just making an N file cache is probably good enough for a long time, the other features can be added later.

Persistent Cache

It would be nice to have the cache survive across server restarts. Although it is also kinda nice to have a clean state on restart, so we would probably have to at least add a cache purge option.

Does this compile on FreeBSD

Hi,
Can you provide compile details ? Can the server compile and run on FreeBSD ?
Does it support subtitles when transcoding ? What formats are supported ?

Best regards

Allow setting server info.

It would be things if info such as server name could be set on the command line.
