adds the ability to answer incoming calls, place outgoing calls and inject
audio into an active call, plus fixes that make call handling work on
current WhatsApp Web.
call:
- accept() answers a call (audio only by default, even for video calls)
- end() hangs up an ongoing call
- playAudio(media) streams a MessageMedia/base64 audio clip to the other party
- isConnected() reports whether the other party has answered
client:
- call(chatId, { video, waitForAnswer, answerTimeout }) places an outgoing call
- getActiveCall() returns the ongoing call, if any
fixes:
- Incoming "call" event: current WhatsApp Web reports calls through
WAWebCallCollection's activeCall attribute; the previous internal-map hook
no longer fires. The map hook is kept as a fallback.
- Call.reject() now goes through the voip stack, which the previous signaling
stanza no longer triggers on current WhatsApp Web.
audio is captured through a synthetic Web Audio stream, so no microphone is
required and it works headless. Adds the browser flags needed for this.

whatsapp Web now asks for confirmation before any call that is not flagged as a user gesture, so startWAWebVoipCall waited on a popup and the call was never placed. Pass the same entry point and trust flag the call buttons use.
builds on the call audio injection so a call can now show a still image or
play a video clip to the other party, in a chosen frame orientation.
- Call.showImage(media) and Call.playVideo(media, { loop }) draw onto a
canvas that is fed through navigator.mediaDevices.getUserMedia, the
camera entry point WhatsApp uses (separate from the microphone one)
- Client.call and Call.accept accept orientation ('landscape', 'portrait'
or 'auto') and resolution; the orientation is fixed for the call and a
portrait frame is pre-rotated so WhatsApp displays it upright
- Call.setVideoResolution changes the resolution during a call
- Requires Google Chrome for H.264; works headless and without a camera

Description
Builds on #201825 (call answering and audio injection) and adds video to calls: show a still image or play a video clip to the other party, in landscape or portrait, at a chosen resolution.
New
Callmethods:showImage(media)shows a still image to the other party for the duration of the callplayVideo(media, { loop })plays a video clip into the call; resolves when it finishes, or immediately when loopingsetVideoResolution(px)changes the outgoing video resolution mid-callNew options on
Client.call/Call.accept:orientation:'landscape'(default),'portrait', or'auto'(follows the first source). Fixed for the whole call.resolution: the short side of the frame in pixels (default 720).Injected audio (
playAudiofrom #201825) works during video calls too, so you can show video and speak at the same time.How
The outgoing camera is acquired through
navigator.mediaDevices.getUserMedia, which is patched to serve a canvas-backed stream instead of a physical camera. A draw loop paints the current source (a still image or a looping video) onto the canvas, andcanvas.captureStream()produces the outgoing frames. No camera is required and it works headless.Notes
Testing Summary
Verified live end-to-end against a real phone: showing a still image, playing a looping portrait video, injected audio playing over the video at the same time, and a mid-call resolution change. Unit tests for the call API are in
tests/call.js.
