Research direction
Start with the snapshotVideo call in the issue's reproduction loop and reproduce it on iOS 15.2 with an iPhone X, using the stated capture rate and isRecording=true. Investigate the reported memory-limit crash and verify completion by running the same sustained capture scenario without the application crashing.

Description
【当前现象】：持续调用 snapshotVideo 到第 23s iOS应用会奔溃
【SDK版本】：tencent_trtc_cloud-2.4.1
【iOS版本】：iOS 15.2
【设备型号】：iPhone X
【是否必现】：必现
【复现步骤】：
在 iOS 15.2 上的 iPhone X 设备上运行应用
调用 snapshotVideo 方法，并设置 isRecording 为 true
在持续调用 snapshotVideo 方法的过程中，平均每秒截取16张图，应用会在第 23s 崩溃
【期望结果】：应用能够正常运行
【代码】：
while (isRecording) {
await Future.delayed(const Duration(milliseconds: captureInterval));
String suffix = DateTime.now().millisecondsSinceEpoch.toString();
String filePath = "$recordStoragePath/${suffix}_temp.jpg";
await client.snapshotVideo(
trtcChannel.isLocal ? null : channel.member.userId,
0,
filePath,
);
}
