Compile OpenCV3 with Cuda7.5 ffmpeg (latest) issue OpenSUSE 13.2
23 janvier 2016, par IngeborgI am using an OpenSUSE 13.2-X86-64 and a Geforce 940M GPU. I want to work with it on the Qt5 IDE.
For this purpose, i have installed my GPU Driver with the Cuda7.5 toolkit rpm from the cudazone. Everything is nearly fine.
It detects everything I have made and executed a couple of the cuda samples.As next step, i have installed the current FFmpeg version with nvenc and other libraries like Xvid and many of
the other usefull stuff which would be to much to list it here. After that i have downloaded the current
OpenCV-3.0.0 source code and ran cmake-gui where i have added cuda, ffmpeg, Qt5 etc and maked it.On different points of the make session (make -j4) i get this kind of mistake from my console (The list of the Multiple definition
error is much longer). This is the first one..

Convert a video to MP4 (H.264/AAC) with ffmpeg
5 décembre 2015, par user176455If I don’t make a mistake, Safari currently need MP4 (H.264/AAC) video encoded for the HTML5
<video></video>element.So I tried to convert a video to this format with
ffmpeg. However when I enter the shell commandffmpeg -i video.flv video.mp4, the returned error is :Seems stream 0 codec frame rate

for output stream #0.1An AAC codec is required but I’m quite newbie with ubuntu and I dont really now how to fix this problem. I’m using Ubuntu 9.10 Karmik Koala (for amd64).
Thank you very much. :)
