MEPlayerItem.duration was truncated to whole seconds, losing sub-second precision for short media files. Preserve the full Double/CMTime value.

这个问题在lgpl分支已经修复了。改成 var duration = TimeInterval(max(formatCtx.pointee.duration, 0)) / TimeInterval(AV_TIME_BASE) 就可以了。你可以申请lgpl授权，就可以返回lgpl分支了。

Heads-up on the red buid check: it is not caused by this branch.

The job fails after ~6-8 seconds, during checkout/setup — before any Swift code is compiled — and it fails identically on PRs that have nothing to do with mine, e.g. #927 (buid fail 8s), which is from a different contributor.

This PR changes one expression in MEPlayerItem.duration plus its test. Nothing in it can affect a job that never reaches the build step. Let me know if you'd like me to rebase or re-trigger once the workflow is healthy.

你的改动没有问题，只是我觉得这个改动太复杂了。只要改成下面这样就可以了。一行代码就解决了。
let duration = TimeInterval(max(formatCtx.pointee.duration, 0)) / TimeInterval(AV_TIME_BASE)

Simplified to the one-liner you suggested — the helper extension and its test are gone, and the duration line is now just:

duration = TimeInterval(max(formatCtx.pointee.duration, 0)) / TimeInterval(AV_TIME_BASE)

Dividing the clamped TimeInterval by AV_TIME_BASE keeps the fractional seconds, the way you described. Thanks for the cleaner direction.
