#486 ISMV

[frank]

MediaInfo.exe (GUI) 0.74 and 0.78 can crash for an ISMV file with the error message "invalid floating point operation". The CLI version and the explorer shelll extension have no problem with the file and report it as MPEG-4 ISML (piff) IIS smoth streaming file format.

No idea what that was about, downloading. Oh, "ducks_take_off" as ISMV. Test with right click, MediaInfo 0.7.99: Invalid floating point operation. CLI 0.7.99: Okay. Explorer info: Okay. CLI info JFTR:

Looking again at this issue, 0.7.99 CLI worked, GUI failed, MediainfoOnline also fails: The "encoding settings" are rather long, maybe too long for the GUI.
