FFprobe 在非常大的 .mov 文件上报告无效 sample_count
FFprobe reports Invalid sample_count on very large .mov file
我有一个 1.1TB ProRes 422 MOV 文件（录制时间超过 24 小时）。
当 运行ning ffprobe -v error -print_format xml -select_streams v:0 -show_format -show_streams "Metadata Error.mov" 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>
但是如果我运行mediainfo，我得到正确的信息：
