Verify Integrity of Video Files
Do any of the currently popular container formats, such as Matroska, have error detection? What can I use to verify integrity of my video files?
I know I should have created and stored checksums. |

Unless you are trying to check files that you already had. Frankly the best way is to watch the file. If it checks out, than create a checksum file and mux it in, so that you can check for sure in the future.
Just out of curiousity, what prompted this? |

Run the files through ffmpeg. Something like:
ffmpeg -i <file> -f avi -benchmark -y NUL It'll show a warning anytime a sync error or corruption is detected, something like "overread" or "backstep" for audio or "slice" or "concealing" for video. Some corruptions look like valid streams to the decoder, though, and you can never know without watching. There's a half-decent chance you'll find a few old errors that you never knew were there, since ffdshow has pretty good error corrections. |
