A bug

If reporting a bug, please fill out the following:

Environment

• pipecat-ai version: main
• python version: 3.12
• OS: macOS

Issue description

Provide a clear description of the issue.

When running SimliVideoService on macOS the following errors occurs continuously:

[swscaler @ 0x148008000] No accelerated colorspace conversion found from yuv420p to rgb24.

This is probably due to the ffmpeg (from PyAV) not being able to optimize image format conversion.

Repro steps

List the steps to reproduce the issue.

Run examples/foundational/26-simli-layer.py.

Expected behavior

No error should show up speeding up image conversion.

Actual behavior

An error is shown but the image conversion happens anyways (slowly).

Logs

Is it possible to use the yuv420p frames directly? The aiortc by default produces them and we converted them to RGB on the Simli integration because it wasn't clear what formats are valid
