這幾天都在測試出現解碼錯誤的問題,
使用Goto掃後面的片段若出現解碼錯誤,則影片看到後面就會嚴重LAG,反之則正常
以下是測試發生解碼錯誤的媒體資訊

結論:
經由不斷的反覆測試,懷疑Video-Writing library : XviD 50涉有重嫌
檔案再1GB以下解碼正常,1GB以上則出現錯誤,這是在 XviD 50會出現的問題。
在Video-Writing library 為ZJMedia MPEG Encoder時,檔案在1GB以上依然順利解碼
小弟對影音解碼沒什麼研究,只是做了簡單的比較,若有不對的地方請多指教~

今天測試發現XviD 50再1G下也會出現解碼錯誤!
而影片看到2/3字幕會消失但沒有LAG

使用Goto出現解碼錯誤,仍可正常播放?
目前推測,非Xvid 50格式且1G以下的檔案能正常播放,但不能使用Goto
