ffmpeg mass add intro to mp4 videos
2 février 2016, par F3rnandI found this script from forums, and a user suggests to use this code to mass add my mp4 files with intro.
for %a in ("*.mp4") do mencoder -ovc copy -oac copy c:\intro.mp4 "%a" -o "c:\temp\%%a"When i use this code on ff Prompt in my Windows Pc. It won’t do anything. I added my data to the location above.
Can anybody explain or suggest how to fix this ?
I also want to know how to mass add outro to all my mp4 files.Thanks
As Requested by mulvya, this is same for all videos as it is generated from same software

FFMPEG not enough data (x y), trying to decode anyway
7 juin 2016, par Forest J. HandfordI’m trying to make videos of Direct3D games using a C# app. For non-Direct3D games I stream images from Graphics.CopyFromScreen which works. When I copy the screen from Direct3D and stream it to FFMPEG I get :
[bmp @ 00000276b0b9c280] not enough data (5070 < 129654), trying to
decode anywayAn MP4 file is created, but it is always 0 bytes.
To get screenshots from Direct3D, I am using Justin Stenning’s Direct3DHook. This produces images MUCH bigger than when I get images from Graphics.CopyFromScreen (8 MB vs 136 KB). I’ve tried increasing the buffer (-bufsize) but the number on the left of the error is not impacted.
I’ve tried resizing the image to 1/6th the original. That reduces the number on the right, but does not eliminate it. Even when the number on the right is close to what I have for Graphics.CopyFromScreen I get an error. Here is a sample of the current code :

}When I search the internet for the error all I get is the FFMPEG source code, which has not proven to be illuminating. I have been able to save the image directly to disk, which makes me feel like it is not an issue with disposing the data. I have also tried only grabbing one frame, but that produces the same error, which suggests to me it is not a threading issue.
