【中文标题】FFprobe 在非常大的 .mov 文件上报告 Invalid sample_count【英文标题】：FFprobe reports Invalid sample_count on very large .mov file 【发布时间】：2018-03-09 07:57:21 【问题描述】：我有一个 1.1TB ProRes 422 MOV 文件（录制时间超过 24 小时）。
运行ffprobe -v error -print_format xml -select_streams v:0 -show_format -show_streams "Metadata Error.mov" 时，我得到以下信息：
<ffprobe>
[mov,mp4,m4a,3gp,3g2,mj2 @ 0000000000709520] Invalid sample_count=-118755256
[mov,mp4,m4a,3gp,3g2,mj2 @ 0000000000709520] error reading header
Metadata Error.mov: Invalid data found when processing input
</ffprobe>
但如果我运行mediainfo，我会得到正确的信息：
