I cannot play large video files... [temporary SOLVED]

[Elisa]

Hi guys,

due I have not a powerful video card I cannot play large video files. The Mediainfo app shows this:

large_movie_screen-info2.jpg

I've tried VLC, KMplayer as well as mplayer in CLI / terminal which says:

So, meanwhile I'll buy a powerful videocard, how I can play that movie:

does anybody know any CLI command which would cause that the video would be "on the fly" resized and simply played in CLI mplayer ?

Or do you know any magic CLI command to resize aka de-/recode movie to such format/size, so the movie clip could be played even on a PC with a slower/weak video card ?
Or maybe to do the job in any GUI app but prefer CLI, if possible

Thanks in advance for any tips or know-how!

Your graphics card supports video up to 1024x1024. So you'll have to resize to that resolution.
This command will resize filename.mp4 to 1024x576 and save it in a file named new-filename.mp4:

Code: Select all

ffmpeg -i filename.mp4 -s 1024x576 new-filename.mp4

It's possible that you need to run this on another computer where the gfx card supports 1280x720.

Thanks AlbertP +1 !
Ok, it's done, one testing file and here are the results:

large_movie_screen-info3.jpg

As for video, it's a bit square-d (1:1, not zoomed etc.) but I couldn't see the original so I am not sure how good the original is.
But unfortunately the audio quality felt down

Is it possible to preserve everything, just changing the size ?
Or is that info in man so have to learn it up?
Ok, I'll sign this as temporary solved, thanks AlbertP.

But if anybody would know any tricks, tips, pls, share them! Thanks.

[AlbertP]

Indeed, ffmpeg doesn't recode very fast. It also can't use your graphics card's video engine so please be patient.

By the way, what graphics card do you have? You can post the output of inxi -Gx here.

BTW, how did you counted the new size ? Is that any ratio / proportional or how I could recount my own, if needing smaller ones etc. Thanks.

[AlbertP]

1280x720 has a 16:9 ratio, and the biggest size your Matrox card supports is 1024 (see the error messages in your first post). 1024 * 9 / 16 = 576. So 1024x576 is the biggest possible 16:9 resolution.

The sound from the old file should be fully preserved. If you want better audio & video quality, you'll probably need to use a more powerful computer for the recoding.

By the way, the 3D driver for Matrox cards will be removed in some future Linux release. I think it'll still be there in 12 but 13 may not have it anymore.
The 2D & video driver will stay so it won't affect playing video files.

Just reading man and just set some switches for preserving codec and 128k bitrate (not 64 as it did), so I'll see when it's done.
