File types & Downloads

  • @burnout426 said in File types & Downloads:

    Your example filenames seem really weird though.

    I somehow modify the initial title when saving, usually not entirely.


    So you say, opening in Classic might help? The player is awesome, it won't only take HLSs.

    Maybe. VLC might be better though and should play HLS streams (last time I checked in a 4.0 dev build at least). VLC will play mp3 files with no extension, so that'll help too. Ctrl + j will show codec information for the file that's playing so you can tell what it is.

  • Thank you!

    Changing the extension of a file doesn't change its content. So, you can change extensions back and forth to whatever you want without harming the file content.

    No, I can't.
    While the file is undefined, I can choose to add an extension to its name, after which the system takes it "away" to hold it as the file's type determination and it is no longer in its name. I can neither change it back nor to another file type.
    Theoretically, MPC could "save as" to another type, but upon such trying I found it either taking too long or failing to proceed, not sure...

    CtrlJ doesn't work in MPC, but I found some properties.
    For an undefined audiofile: Audio: MPEG Audio Layer 3 48000Hz stereo 320kbps [Audio].
    For a "Film" type "audio only" file: Audio: MPEG Audio Layer 3 44100Hz stereo 192kbps [Audio].
    For an undefined videofile: Video: MPEG4 Video (H264) 428x240 25.00fps [Video] Audio: AAC 22050Hz stereo 705kbps [Audio].
    Does MPEG mean "mp3"?
    The "film" type might manifest in an "avi" extension. What extension would manifest this "Video recording" type? It's used by the Windows MovieMaker.

    Do you have "hide extensions for known file types" checked in Explorer's folder options? It's the default unfortunately and you should always uncheck it.

  • @burnout426 How do you do that?
    I didn't find it in the folder menu. System settings?

    I found a performance issue with some video files.
    In the past, all downloaded files ran o'k with my MPC. In some recent years, some start exhibiting sound not synchronised with the picture; but just recently it appeared same files ran o'k in my WMP. The difference would be made if I'm able to ^rename^ such files with .avi instead of .mp4, don't you think?
    Well, I like MPC, but it doesn't seem to have any autoupdate function nor does it even have an "update" option - only I found a link somewhere there, not been yet... (I'm not sure if I should: things've been alright with minor issues, what if I update and it stops working?)

    Since I don't know what Windows version you are on, here is a description for Windows XP up to Windows 10.

  • @yanta

    Windows XP

    In Windows Explorer, choose Tools > Folder Options.

    Click the View tab in the Folder Options dialog box.

    In Advanced Settings, select Show Hidden Files and Folders.

    Deselect Hide Extensions for Known File Types.

    Click OK.

    Found it.
    But why should I "select Show Hidden Files and Folders"? They're in separate listings and are they at all relevant to one another?


    Anyway, if I do this "Deselect Hide Extensions", what possible complications, if any, could it infer? (And I hope I can revert it the same way if anything at all...)

  • @joshl

    But why should I "select Show Hidden Files and Folders"?

    The webpage I linked to describes also how to show hidden files and foldes, however, you don't need to change that setting, only what @burnout426 mentioned (= to unhide extensions for known file types).

    Anyway, if I do this "Deselect Hide Extensions", what possible complications, if any, could it infer?

    There are no possible complications, it's quite the contrary, not to hide extensions for known file types means an increase in safety.

    And I hope I can revert it the same way if anything at all...)

    Yes, you can.

    Exactly.

  • Funny thing.

    I downloaded a video file to which the browser assigned the .mp4 extension.
    Funny thing it wouldn't synch in either of my players (WMP & MPC).
    I tried stripping it with no extension - no synch.
    I tried .mpg - it synched in my WMP.
    WTF?
    Yeah, the most funny thing is that my MPC said it was actually a MPEG Layer 4 file...
    Well, I can't establish a law of physics yet, but the liter the file the less possibility of such synching problems. Meaning density-like: up to a hundred per 40-minute episode, like lower quality or something... Usually meaning 240p is o'k. Usually, maybe...

    Thank you for your pointing me out to that setting, I wouldn't do without it.
    (:

  • Opened an old video here.
    It was a browser download or something. The file downloaded as .avi - so it was .avi. I opened it with my MPC: Shift F10 - second tab said it was Xvid, but I opened the third tab there - it said video was MP4. What does that mean?
    Just curious. Plus it might mean something considering better use and knowledge...

  • @joshl Sound like it's an mpeg-4 video in an avi container (as opposed to an mp4 container). The mention of xvid might be due to the specific version of mpeg-4 (mpeg-4 part 2 asp profile) that's being used.

  • @burnout426 I saw something about "advanced video codec", forgot. In the third tab there. I guess it's something like AAC but for the picture...

  • @burnout426 So, when I see "H.264" in tab 2, it's practically it? Yeah, there's often (usually) some additional stuff in tab 2 regarding the video (though not only), like sometimes, some dimensions differ from the resolution, one written with a ":", the other with some "x" (wondered about that).

  • @joshl The order of the tabs in my MPC is "Details", "Clip", "Media Info". If you see "(H264)" for "video" on the Details tab, that's good enough. But, you can use that plus the General and Video info on the "Media Info" tab to get the full picture.

    Or, you can just hit ctrl + j in VLC. You might like the way they list the info better.

  • @burnout426 Maybe.
    Tab 1 only shows info listed in your file system. If you stream a file from the Web, it says many idontknows there, nor does it show the inner package, like you said the second tab does.
    For some time I didn't look at the content of the third tab, only that ".avi" time I did.

    ok.

    Tried renaming an old "H.264" file with an .avc - my system didn't recognise it:)
    I surmise I might just stick with the .mp4🙂
