Rust rewrite I should have submitted/pushed more incrementally but just played with it on my computer as I was learning the language. The new Rust version more or less matches the functionality of the current C++ version, although there are many caveats listed below. Upgrade notes: when moving from the C++ version, I recommend dropping and recreating the "recording_cover" index in SQLite3 to pick up the addition of the "video_sync_samples" column: $ sudo systemctl stop moonfire-nvr $ sudo -u moonfire-nvr sqlite3 /var/lib/moonfire-nvr/db/db sqlite> drop index recording_cover; sqlite3> create index ...rest of command as in schema.sql...; sqlite3> ^D Some known visible differences from the C++ version: * .mp4 generation queries SQLite3 differently. Before it would just get all video indexes in a single query. Now it leads with a query that should be satisfiable by the covering index (assuming the index has been recreated as noted above), then queries individual recording's indexes as needed to fill a LRU cache. I believe this is roughly similar speed for the initial hit (which generates the moov part of the file) and significantly faster when seeking. I would have done it a while ago with the C++ version but didn't want to track down a lru cache library. It was easier to find with Rust. * On startup, the Rust version cleans up old reserved files. This is as in the design; the C++ version was just missing this code. * The .html recording list output is a little different. It's in ascending order, with the most current segment shorten than an hour rather than the oldest. This is less ergonomic, but it was easy. I could fix it or just wait to obsolete it with some fancier JavaScript UI. * commandline argument parsing and logging have changed formats due to different underlying libraries. * The JSON output isn't quite right (matching the spec / C++ implementation) yet. Additional caveats: * I haven't done any proof-reading of prep.sh + install instructions. * There's a lot of code quality work to do: adding (back) comments and test coverage, developing a good Rust style. * The ffmpeg foreign function interface is particularly sketchy. I'd eventually like to switch to something based on autogenerated bindings. I'd also like to use pure Rust code where practical, but once I do on-NVR motion detection I'll need to existing C/C++ libraries for speed (H.264 decoding + OpenCL-based analysis).

switch to ffmpeg with compile fix for Linux/arm For the moment, this is my own fork of the ffmpeg crate on github with this one fix: https://github.com/scottlamb/rust-ffmpeg/commit/a67d25cb85369597e0e4820172330e8a3168589f

Rust rewrite I should have submitted/pushed more incrementally but just played with it on my computer as I was learning the language. The new Rust version more or less matches the functionality of the current C++ version, although there are many caveats listed below. Upgrade notes: when moving from the C++ version, I recommend dropping and recreating the "recording_cover" index in SQLite3 to pick up the addition of the "video_sync_samples" column: $ sudo systemctl stop moonfire-nvr $ sudo -u moonfire-nvr sqlite3 /var/lib/moonfire-nvr/db/db sqlite> drop index recording_cover; sqlite3> create index ...rest of command as in schema.sql...; sqlite3> ^D Some known visible differences from the C++ version: * .mp4 generation queries SQLite3 differently. Before it would just get all video indexes in a single query. Now it leads with a query that should be satisfiable by the covering index (assuming the index has been recreated as noted above), then queries individual recording's indexes as needed to fill a LRU cache. I believe this is roughly similar speed for the initial hit (which generates the moov part of the file) and significantly faster when seeking. I would have done it a while ago with the C++ version but didn't want to track down a lru cache library. It was easier to find with Rust. * On startup, the Rust version cleans up old reserved files. This is as in the design; the C++ version was just missing this code. * The .html recording list output is a little different. It's in ascending order, with the most current segment shorten than an hour rather than the oldest. This is less ergonomic, but it was easy. I could fix it or just wait to obsolete it with some fancier JavaScript UI. * commandline argument parsing and logging have changed formats due to different underlying libraries. * The JSON output isn't quite right (matching the spec / C++ implementation) yet.
