System frames are now queued. Before, system frames could be generated from any
task and would not guarantee any order which was causing undesired
behavior. Also, it was possible to get into some rare recursion issues because
of the way system frames were executed (they were executed in-place, meaning
calling `push_frame()` would finish after the system frame traversed all the
pipeline). This makes system frames more deterministic.
Before CancelFrames didn't need to be waited for because system frames were
processed in-place and therefore calling push_frame() would finalize after it
traversed all the pipeline. Now, system frames are queued so we need to wait
until CancelFrame reaches the end of the pipeline.
- Restore TextInputMessage.realtimeInput structure for correct API format
- Remove invalid turnComplete message from _send_user_text method
- turnComplete is only valid for clientContent, not realtimeInput messages
- realtimeInput text completion is automatically inferred by the API
This fixes WebSocket 1007 errors caused by mixing realtimeInput and
clientContent message types in violation of the Gemini Live API contract.
Fixed a line length issue in tavus.py where the on_transcription_stopped callback was exceeding the maximum line length. Split the partial() call across multiple lines for better readability and compliance with project style guidelines.
As suggested in PR review, removed the _on_transcription_stopped and
_on_transcription_error method definitions. Now using the consistent
partial(self._on_handle_callback, ...) pattern for these callbacks,
matching how all other callbacks are handled.
This simplifies the code while maintaining the same functionality.
This was sending a 1007 because it was wrapping RealtimeInput in the json.
- Updated the `TextInputMessage` class to directly store text input as a string.
- Modified the `from_text` class method to create an instance using the new `text` attribute.
TavusTransport was broken in Pipecat 0.0.77 due to PR #2292 adding required
callbacks (on_transcription_stopped, on_transcription_error) to DailyCallbacks.
This fix adds placeholder implementations of these callbacks to TavusTransportClient,
allowing TavusTransport to initialize properly. These callbacks are not used by
Tavus (which handles avatar video, not transcription) but are required by the
DailyCallbacks validation.
Fixes initialization error:
- 2 validation errors for DailyCallbacks
- on_transcription_stopped: Field required
- on_transcription_error: Field required
