Thanks HolyWu.

ChaosKing,
I think you were keeping list of file extensions that LSmashVideoSource could deal with.
Playing with MediaInfo 19.07, I noticed this

So I've added missing ones to my list of ISO file extensions that LSmashVideoSource/LSmashAudioSource can open.
Complete list.

    Function IsISOFileName(String s)        {s=RT_GetFileExtension(s) Return(s==".mov"||s==".mp4"||s==".m4v"||s==".3gp"||s==".3gpp2"||s==".3g2"||s==".mj2"||s==".dvb"||
                                            \ s==".dcf"||s==".m21"||s==".m4a"||s==".m4b"||s==".m4p"||s==".k3g"||s==".jpm"||s==".jpx"||s==".mqv"||s==".ismv"||s==".isma"||s==".f4v")}

Or bare.

mov, mp4, m4v, 3gp, 3gpp2, 3g2, mj2, dvb, dcf, m21, m4a, m4b, m4p, k3g, jpm, jpx, mqv, ismv, isma, f4v
