Two products described as “Linux devices” can have very different processor architectures, toolchains, audio drivers and available memory. A precise device brief is therefore more useful than a general request for low-latency video. Put the following information into one working document and give every unknown item an owner and a confirmation date.
Operating system and build environment
Provide the chipset, processor architecture, operating system version, runtime libraries, compiler toolchain and application language. If the product has several hardware revisions, identify the exact models required for the first release. Avoid substituting a chipset family name for the production configuration.
Explain application permissions, installation and update methods, background execution requirements and the diagnostic information available from production firmware. An SDK compiling successfully is a useful checkpoint, but it does not settle runtime behavior or future maintenance.
Keep development-board information separate from production-device information. Differences in memory, drivers and system configuration should remain visible throughout the assessment.
Media inputs and outputs
List camera and microphone access methods, whether media is supplied as raw or encoded data, available encoders, speaker output interfaces and timestamp sources. Explain whether local recording, recognition software or another application also uses the same media.
If access depends on a manufacturer-specific interface, obtain its documentation and a working sample early. When the application cannot access live media, resolve that device dependency before treating the RTC work as a straightforward SDK integration. Browser media specifications are useful background, but they do not substitute for a native platform’s actual interfaces.
Include the audio-processing arrangement where it is known. The team should understand which component is responsible for local processing before trying to troubleshoot the complete remote conversation.
Networks and participant relationships
Specify Wi-Fi, wired or cellular connectivity, the intended markets and whether devices will enter enterprise networks. Identify the receiving client: browser, app or another device. Describe one concrete session, such as a robot speaking with one mobile user while an administrator joins only for support.
Explain device binding, who can initiate a call, how credentials are obtained and refreshed, and what should happen to media after hanging up. Business authorization should be designed across the application; knowing a room identifier is not itself evidence that a participant should have access.
Resource budget and validation materials
Provide available CPU capacity, memory, battery and thermal headroom under representative product load. When measurements are missing, schedule them. Idle-device observations should not silently become the production budget.
Prepare a sample device, a repeatable local media demonstration, the intended launch window and the first acceptance task. Separate confirmed conditions, items requiring device tests and questions awaiting supplier answers. This gives integration scope and quotations a shared basis.
The checklist is general preparation guidance. Compatibility and performance must be checked against the specific SDK and device versions. For an RTC integration and pricing assessment, submit a summary through the inquiry form; do not include device secrets or access credentials.
