rerun 是做什麼的?
使用 rerun.experimental.Mp4Reader 將 .mp4 影片擷取至 Rerun chunk 串流。閱讀時需了解如何將影片轉換為 VideoStream、選擇串流或資產模式、透過 FFmpeg 進行轉碼(B 幀、輸出編碼器、GOP 大小),或將影片 PTS 對齊到錄製的牆鐘時間軸。建構於 rerun-chunk-processing(串流機制)和 rerun-data-model(影片在錄製中的資料歸屬)之上。
透過 rerun.experimental.Mp4Reader 將 .mp4 影片擷取至 Rerun chunk 串流。適用於將影片轉換為 VideoStream、選擇串流或資產模式、透過 FFmpeg 進行轉碼(B 幀、輸出編碼器、GOP 大小),或將影片 PTS 對齊到錄製的牆鐘時間軸。
此技能主要圍繞 Rerun 生態系統中的影片資料處理,提供一個名為 `rerun.experimental.Mp4Reader` 的 API,用於從 .mp4 檔案中讀取並將之轉化為 Rerun 的 chunk 串流。使用場景包括:將影片載入為持續串流的 `VideoStream` 或一次性完整加載的資產模式;利用 FFmpeg 進行轉碼參數控制(如處理 B-frames、設定輸出編碼器、調整 GOP 大小);以及將影片的呈現時間戳記(PTS)對齊到錄製的牆鐘時間軸上,以確保多模態資料的時間同步。底層依賴 `rerun-chunk-processing` 處理串流機制,以及 `rerun-data-model` 定義影片在錄製中的資料歸屬與結構。支援平台包括透過 Rerun SDK(Python 或 Rust)整合的自訂視覺化工具。
