+== TODO
+=== TODAY
+ - [x] Commit libalabaster build update.
+ - [x] Commit stela changes.
+ - [ ] Commit ffmpeg build update.
+ - [ ] Consolidate spng, stb_img, and wuffs into one file with server/client ifdefs
+ - [ ] Startup timing information
+  - From main() to window_system_main() then everything in desktop_open().
+     - Might as well work on the cleanup part too.
+ - [ ] Packet benchmark.
+  - Create packet, write bunch of ints, send to another thread, thread adds everything.
+ - [ ] RPC header packing.
+  - [ ] Look for more obvious packet_stream/rpc optimizations.
+
+=== DMMN
+ - [ ] List lock.
+ - [ ] Reconnect/Reseek.
+ - [ ] Verbose connection logging.
+ - [ ] List clear.
+
+=== List
+ - [x] list.c:294 assert.
+  - Very common in testing with remote client (SINK_LOCAL-only theory still possible).
+ - [ ] Better name for set_current() type functions.
+ - [ ] Fix ref counting and unloading.
+ - [ ] List unset.
+  - [ ] Cleanup pizzabot.
+ - [ ] Gapless/Queued.
+  - Consider case where an entry gets queued on the sink at a point when the list already
+    expects it to be playing.
+ - [ ] list_close(): Free resources if no sinks or wait for all sinks to be removed then free resources.
+ - [ ] End on a paused entry should advance with the next entry starting paused.
+ - [ ] Allow ended entry to be unpaused (skip to next).
+ - [ ] Factor in estimated ping.
+  - Per-sink?
+ - [ ] Use ended state sink-side?
+  - Never set ended entry?
+ - [ ] Docs.
+
+=== Sink
+ - [x] CTRL+C twice forces SIGINT.
+ - [ ] Synced pausing is broken when video processing falls massively behind.
+   - Will cause 'Requested PTS is lower than oldest frame in video_buffer'.
+ - [ ] Mark entries for removal rather than remove in-place.
+ - [ ] More optimal command queue.
+
+=== Cache
+ - See cache/entry.h.
+ - [ ] EOF when seeking forward in slow http source.
+ - [ ] HTTP timeout.
+
+=== Liana
+ - [ ] Node connection pool.
+  - [ ] One "connection" object should suffice for retrieving duration, handling stream, and loading visual data for client.
+
+=== VCR
+ - Proper "Whole File" implementation.
+  - [ ] Track loop count, reset on flush?
+  - [ ] Reject images.
+ - [ ] Internalize "packet cache" logic.
+
+=== Codecs
+ - [ ] Better wuffs support.
+ - [ ] https://snisurset.net/code/abydos
+
+=== Desktop/CMV
+ - [ ] Consistent cleanup on errors.
+  - Start from desktop.c:camu_desktop_open().
+ - [ ] More visual sink-only status.
+  - [ ] mpv/libplacebo shaders.
+  - [ ] Diagonal swipe for pause.
+  - [ ] Motion blur for next/prev.
+   - Nintendo switch photo viewer-like.
+  - [ ] Overlay text for volume.
+ - [ ] Idle animation.
+   - https://www.shadertoy.com/view/wtsXRX
+
+=== Renderer
+ - [ ] vaapi fallback if Vulkan decoding not available.
+ - [ ] Command queue.
+  - [ ] Queue creation/deletion.
+  - [ ] Texture upload.
+ - [ ] MOMO frame queue.
+ - [ ] Log when scaling flips from required to not and vice versa.
+
+=== CMC
+ - [ ] Browse pane.
+  - [ ] Tile implementation.
+ - [ ] Flesh out "user" concept enough to be usable.
+
+=== Portal
+ - [ ] Post cache thread-safety.
+ - [ ] https://github.com/lwthiker/curl-impersonate
+
+=== Node
+ - [ ] Implement node paradigm.
+ - [ ] Allow cmv to act as a node.
+
+=== libnaunet
+ - [ ] Native Windows file backend.
+  - https://learn.microsoft.com/en-us/windows/win32/api/minwinbase/ns-minwinbase-win32_find_dataa
+
+=== Stela
+ - [x] X11/common nix Vulkan.
+ - [x] GLFW Vulkan destroy surface.
+ - [-] X11 and GLFW cursor.
+  - [x] Xcursor
+ - [-] Fix vaapi on x11.
+  - It's actually Xwayland lacking dma import extension.
+ - [ ] Configurable depth and stencil buffer.
+ - [ ] Consider server-side transcode in terms of the build.
+  - If video decode specific GPU device wiring is needed, should it be in stela?
+ - [ ] Latency tweaking.
+  - Wayland presentation timing.
+  - https://github.com/ishitatsuyuki/LatencyFleX
+
+=== Other Optimizations
+ - [ ] Walk up cmv and document program design.
+ - [ ] Memory pool for al_alloc_object.
+ - [ ] alloca str_to_c_str.
+
+=== Style
+ - [ ] Pass on log levels.
+ - [ ] Rename mutex variables to lock.
+
+=== Tests
+ - [ ] Emulate slow packet stream connection.
+  - ev_set_io_collect_interval() in loop.c.
+ - [ ] Fast open -> shuffle spam -> disconnect deadlock.
+ - [ ] Simulate ping, connection speed, connection instablitiy.
+ - [ ] Seek again before slow client can respond to the first seek.
+ - [ ] al_array_contains
+ - [ ] al_array_unsorted_search_by_key
+
+=== Build
+ - [x] Allow forcing ffmpeg-compat.
+  - 3 levels? latest, 4, 3.
+ - [x] allow --force-fallback-for=libavcodec.
+ - [x] Allow selecting window from camu.
+  - [x] 'guess' option
+ - [x] Don't require shaderc if libplacebo found.
+ - [x] Audio optional based on if libpulse/libasound are found.
+ - [x] libalabaster option for release build with asserts (al_assert only).
+
+=== External
+ - [ ] miniaudio dsound flush.
+ - [ ] notcurses ffmpeg flush/reset.
+
+=== camu_db
+==== Transfer
+ - [ ] json.dumps(d).decode('unicode-escape').encode('utf8')
+ - [ ] Index all posts.
+ - [ ] Impement remake_post() using raw responses.
+ - [ ] Estimate size requirement.
+ - [ ] Re-write database using moves for resources.
+
+==== Status
+ - [ ] Merge run/* in some way that respects the file dates.
+ - [ ] Move original pixiv into proper DB.
+  - [ ] Verify whether pixiv_app returns updated date or created date.
+  - [ ] Flag with unchecked updated date.
+ - [ ] Move in twitterN/pixivN temporary directories.
+  - Clear up significant space.
+  - Rewrite everything with moves.
+ - [ ] Setup system for downloading a list of tweet IDs.
+  - [ ] Download likes.
+  - [ ] Download missing? Twitter posts.
+ - [ ] Proper format for TikTok.
+ - [ ] Proper format for Youtube.
+ - [ ] Sort out and attempt to source various loose files.
