Winscope에서 탐색을 위해 여러 트레이스 간에 상태를 매핑하지 못했습니다. Winscope 버그를 신고하고 트레이스를 첨부합니다.
<table>의 하나 이상의 항목에 vsync_id 값이 누락됨
VSync ID 정보가 누락되어 Perfetto 트레이스를 로드할 수 없습니다.
Winscope 버그를 신고하고 트레이스를 첨부합니다.
중복된 SF 레이어 ID <layerId>가 발견됨 - 계층 구조에 중복으로 추가
SurfaceFlinger 트레이스에 동일한 layerId가 있는 레이어가 두 개 포함되어 있습니다.
SurfaceFlinger 버그를 신고하고 트레이스를 첨부합니다.
화면 녹화는 다른 트레이스와 동기화되지 않을 수 있습니다.
메타데이터에 경과 시간이 아닌 단조 시간이 포함됨
화면 녹화 파일이 오래되었으며 동기화할 수 없는 기존 메타데이터 형식을 사용합니다. 최신 버전의 Android에서 스크린 녹화하면 이 문제가 발생하지 않습니다.
일부 전환을 파싱할 수 없습니다. 전환 보기 도구에서 일부가 누락될 수 있습니다.
기존 전환 트레이스를 파싱할 수 없으므로 뷰어에서 데이터가 누락될 수 있습니다.
<filename>: <error>
매핑되지 않은 기타 오류 Winscope 버그를 신고하고 트레이스를 첨부합니다.

Click **Upload another file** to upload more traces or\nclick **X** to remove uploaded traces.\n\n**Figure 1.** Upload traces in Winscope.\n\nClick **View traces** to view the uploaded traces. Tabs for each trace\nappear on the top panel of the window. If the uploaded file contains the\nrelevant traces, a floating view of the screen recording trace or screenshot is\noverlaid on the screen.\n\nSee [Analyze traces](/docs/core/graphics/winscope/analyze/overview) for more information.\n| **Note:** The supported trace file types are Winscope traces (in Perfetto or legacy proto format), screenshots, MP4 videos with Winscope metadata (collected with adb screenrecord), zip files, gzip file, and bug reports.\n\nParse warnings and errors\n-------------------------\n\nWinscope uses a snackbar to display issues found when loading a trace, such as\nwhen a trace file is discarded because the data is old. The following list\nincludes the current warnings and their meanings:\n\n| Message | Description |\n|-----------------------------------------------------------------------------------------------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| *corrupted archive* | Failed to load the zip file. This usually happens when the zip is empty (0 bytes). |\n| *`\u003cfilename\u003e`: discarded because data is old* | Any traces that finish more than 5 minutes before the next trace starts are discarded. |\n| *`\u003cfilename\u003e`: discarded because data is older than `\u003ctime\u003e`* | Based on the most recent monotonic or boot time offset found, any traces with an offset greater than 5 seconds are discarded. |\n| *`\u003cfilename\u003e`: overridden by another trace of type `\u003ctrace type\u003e`* | When equivalent traces (for example, trace and dump) exist in the same file, Winscope uses the following rules: - Perfetto traces override legacy traces of the same type. - Screen recordings override screenshots. |\n| *`\u003cfilename\u003e`: overridden by another trace of same type* | When traces of the same type exist in the same file, Winscope uses the following rules: - Perfetto traces override legacy traces of same type. - The largest Perfetto trace overrides all other Perfetto traces. - Traces overrides dumps for WindowManager and SurfaceFlinger. |\n| *`\u003cfilename\u003e`: unsupported format* | The legacy trace can't be parsed due to an invalid proto or missing Winscope parser. |\n| *Failed to create `\u003cparser_name\u003e` parser: `\u003cerror\u003e`* | Winscope identified the trace parser but couldn't parse the file. *File a Winscope bug and attach your trace.* |\n| *Cannot visualize all traces: Failed to initialize timeline data. Try removing some traces.* | Winscope failed to parse timeline data from the trace. *File a Winscope bug and attach your trace*. |\n| *Error occurred in frame mapping: `\u003cerror\u003e`* | Winscope failed to map the states between different traces for navigation. *File a Winscope bug and attach your trace*. |\n| *Missing `vsync_id` value for one or more entries in `\u003ctable\u003e`* | Failed to load Perfetto trace due to missing VSync ID information. *File a Winscope bug and attach your trace*. |\n| *Duplicate SF layer ID `\u003clayerId\u003e` found - adding it as **Duplicate** to the hierarchy* | SurfaceFlinger trace contains two layers with the same `layerId`. *File a SurfaceFlinger bug and attach your trace*. |\n| *Screen recording may not be synchronized with the other traces. Metadata contains monotonic time instead of elapsed* | The screen recording file is old and uses legacy metadata format that can't be synchronized. Screen recordings from newer versions of Android shouldn't have this issue. |\n| *Cannot parse all transitions. Some may be missing in Transitions viewer.* | Unable to parse the legacy transitions trace, data might be missing from the viewer. |\n| *`\u003cfilename\u003e`: `\u003cerror\u003e`* | Other unmapped errors. *File a Winscope bug and attach your trace*. |"]]
