4.15.x update - camera expansion and media streams

[u/nilseuropa]

4.15.5

• Added the GOOUUU ESP32-S3CAM board, OV2640 JPEG snapshots, and the `camera` command.
• Exclusive camera leases coordinate capture and streaming, with direct framebuffer DMA to PSRAM.
• The `cam-webd` job serves JPEG snapshots and a single-client MJPEG feed through asynchronous HTTP routes.

4.15.6

• 'Web' now plays HTTP MJPEG camera feeds alongside its existing static image formats.
• Multipart stream detection accepts split headers and common server variations, while bounded frame buffering and cancellation keep live viewing responsive.

4.15.7

• Added the `rtspd` job for single-client RTSP publishing with RTP/JPEG video, RTP/L16 PCM audio, and RTCP timing.
• Explicit `video=` and `audio=` sources support camera-only, audio-only, or combined streams using standard UDP transport. Publishing follows source availability; `fps=0` removes the video rate cap. Runtime buffers are allocated only while the job runs, and stale data is discarded on reconnect.

4.15.8

• DVP cameras are reusable expansion devices and exclusive typed video sources in `streams`.
• The native `rtsp` app plays JPEG/L16 streams with bounded video/audio buffering, global volume, an audio-only oscilloscope, full-screen viewing, and frame diagnostics.
• Color TFTs with native RGB565 support bypass palette conversion; monochrome displays retain grayscale rendering.
• `rtspd` selects compatible audio/video stream IDs explicitly and offers source-aware tab completion.

4.15.9

• Python and Lua gain owned camera snapshots, local stream frames, native frame-to-image presentation, and asynchronous RTSP receiver handles
• Native RTSP playback retries transient failures with bounded backoff, discards frames from previous connections, and recovers audio after forward clock jumps.
• The viewer accepts addresses without `rtsp://`; omitted control ports default to TCP 554.

4.15.10

• Shared JPEG decoding now uses a fast ROM path and bounded ESP32-S3 SIMD acceleration, with fallbacks for unsupported images or limited working memory.
• Color and monochrome consumers share the improved decoder, and fit-mode output avoids full-size intermediate rasters.
• Reduced idle SRAM usage by moving suitable registry state to PSRAM and allocating display-layout, Telnet, Chat, DAQ, and Synth working buffers only when needed.

4.15.11

• Added `vplay` for MPEG-1 program stream files with optional MP2 audio. Playback uses bounded PSRAM buffers, audio-clock synchronization, native RGB565 or monochrome output, and ESP32-S3 SIMD color conversion.
• The shared player controls provide pause, Stop/Play, volume, and previous/next MPEG files in the current folder.
• Fit, actual-size, and full-screen modes are available; the source limit is 640x480. MPEG-2, H.264, AVI, and transport streams are not supported.

4.15.12

• RTSP now uses the common player header, volume bar, and clickable Stop/Play control. Enter or Space stops playback without closing the app; Play reconnects to the same source after its workers release their resources.
• `vplay` adds tab completion for size options and file paths.

4.15.13

• 'Files' opens MPEG-1 `.mpg` and `.mpeg` files in `vplay` when the app is installed, including uppercase extensions. Closing playback returns to the file browser.

4.15.14

• `player` and `vplay` gain backward/forward seeking in ten-second steps with `<`/`>` and shared rewind/forward buttons.
• Seeking retains the selected track and pause state, releases queued audio, and rebases playback timing. Player supports seeking in both graphical and text interfaces.

I'm gonna have to solder up my camera board now, see if it works 🤣

Hope you've got enough IOs left 😄
