How to compress an .mp4 [on hold]
11 novembre 2014, par FTLRalphI have an .mp4 file I generated from the jcodec library. The filesize seems a bit on the high side compared to other .mp4 files I’ve seen (a 360-frame .mp4 at 640x360 came to about 13mb).
I can’t seem to find anything about compression from jcodec (the lack of documentation doesn’t help much). I was wondering if there’s another library I can use to possibly pass in this .mp4 file and get a smaller one in return ? Or some other solution ?
I understand I can lower the bit rate with jcodec (which in turn reduces file size) but going anything below 256 leaves very obvious video artifacts.
Oh, and this is all pure video - no sound. And I’m also referring to actual code/libraries, not programs.

ffmpeg burn ass subtitle to mp4. The properties WrapStyle(0:word wrap, 1 : the char '\N' or movie edge force change line, 2 : only \n and \N change line).


English subtitle run OK.
Chinese subtitle has no word wrap when WrapStyle=0.

Jwplayer function snapshot using ffmpeg and php
5 janvier 2021, par Offboardbefore anything I'm using version 6, then the Snapshot plugin does not work.



I'm finally with 2 questions, take a sequence of photos of a percentage of the video, so googled it and got this code from ffmpeg :



ffmpeg -i video.mp4 -r 0.5 -f image2 output-%05d.jpeg




so far so good, but I do not know how to take a screen shot of the video by setting the time, if I'm right this code is per frame.



I searched again to get the function that calls the images, to generate good is quite simple, but the problem is that I found the pictures looks is all in one look.



if anyone has any function or know how to do please tell me : D
My English sucks, so do not call if I messed up.
