Win10Pro64; Release 2.7.3. I've been using Avidemux for a couple of years without issues. I recently got two new .avi files, and when I try to open them, I get a message box saying "Attempt to open [name].avi failed!" followed by a message box saying "Could not open the file." These files play fine in VLC Media Player, Windows Media Player, and a couple of other programs as well. My initial attempts were from my hard drive, but I also tried the same files directly from the flash drive that held them originally. Same results. Can anyone suggest what might be wrong, or how I can rectify the situation so I can edit them?
Could you please post the textual output of MediaInfo for these .avi files?
A bit much to type. Here's a screenshot.
I meant the text output by MediaInfo (https://mediaarea.net/en/MediaInfo) tool which you copy and paste into your reply, almost no typing involved. But I already can suspect that the problem is related to files containing Type 1 DV stream (https://docs.microsoft.com/en-us/windows/win32/directshow/dv-data-in-the-avi-file-format) while Avidemux supports only Type 2.
You should remux the files in copy mode with FFmpeg to convert them to Type 2 first.
ffmpeg -i "SourceDrive:\FullPathTo\SourceFile.avi" -c copy "TargetDrive:\FullPathTo\OutputFile.avi"
eumagga0x2a... You're correct about the files being Type 1. I contacted the person who created them for me, and he confirmed. Thank you for your help. Wendi
