Suggestion

When Kbox 11 is used as the client to receive streams from a video stream cloud phone, the image freezes after 10 minutes. The receiving frame rate and decoding frame rate are both 0. The fault affects the testability of long-term stability of the video stream engine. It can be rectified after reconnection.

The software decoding performance of the Kbox 11 emulated device is insufficient, and the decoding delay is high.

When the system software decoding interface freezes, the decoding thread of the video stream engine client cannot obtain a new buffer to receive stream packets from the server.

After multiple retries time out, the decoding function of the video stream engine client enters the error handling process and the decoding thread exits.

The performance of the Android native decoder built in Kbox 11 is poor. Further analysis is required.

Currently, the native software decoding interface of Kbox 11 is used only by its own gallery. Mainstream video players such as XPlayer, Tencent Video, TikTok, and iQIYI use their own FFmpeg software decoding interfaces or self-developed software decoding interfaces instead of the native software decoding interface of Kbox. Therefore, the impact scope of poor software decoding performance is limited.

Use the Kbox 9 emulated device as the client.

Continue to analyze the problem with the native software decoding performance and locate the root cause. If the problem lies in the native decoder, no solution will be provided. If the problem is related to integration, continue to solve the problem.

Minor

The build tool Gradle 7.5.1 has a vulnerability (CVE-2023-26053).

On March 9, it was reported that Gradle 7.5.1 had a vulnerability (CVE-2023-26053). The video stream engine in this delivery adopts Gradle 7.5.1.

1. The vulnerability of the build tool does not affect the final binary, thus imposing no risk on the live network.
2. After vulnerability analysis, it is found that this delivery is not affected by this vulnerability.

This delivery is not affected by the vulnerability and no workaround is required.

Currently, no other Gradle versions are available, and the vulnerability has no impact on this delivery. After Gradle 8.0.1 is available, the build tool will be upgraded from 7.5.1 to 8.0.1 to resolve this vulnerability.
