Déploiements possibles
31 janvier 2010, parDeux types de déploiements sont envisageable dépendant de deux aspects : La méthode d’installation envisagée (en standalone ou en ferme) ; Le nombre d’encodages journaliers et la fréquentation envisagés ;
L’encodage de vidéos est un processus lourd consommant énormément de ressources système (CPU et RAM), il est nécessaire de prendre tout cela en considération. Ce système n’est donc possible que sur un ou plusieurs serveurs dédiés.
Version mono serveur
La version mono serveur consiste à n’utiliser qu’une (...) -

ffmpeg, lower fps with gpu - too many packets buffered
29 mai 2020, par AlterI'm trying to lower the fps for a large set of videos. Unfortunately, I don't have much experience with ffmpeg



This is my current command, which is a hybrid of multiple posts. At this point it's more guess work than anything else



ffmpeg \
 -y -hwaccel_output_format cuda -hwaccel_device 0 -hwaccel cuvid -c:v mpeg2_cuvid \
 -i myinput.mp4 -r 25 -c:v hevc_nvenc-b:v 128K -strict -2 -movflags faststart \ 
 /workspace/videos/24fps_trial2/rat1-control2.mp4 -c:v hevc_nvenc




The gist of it is just that I'm trying to lower fps and use hardware acceleration since my dataset is large



The message I get is



Trailing option(s) found in the command: may be ignored.
[mov,mp4,m4a,3gp,3g2,mj2 @ 0x453a100] decoding for stream 0 failed

Attempting to compile FFmpeg 4.2.3 statically for Windows 10 (x86_64), but binaries asks for missing DLLs
29 mai 2020, par ExpectatorI am using Msys MinGW (x86_64) and pulled a snapshot of the latest major release of FFmpeg off of their website. Here is my
./configure
options. I plan to use the binaries on both the computer that I compiled it on, and other Windows computers that I own.


./configure --enable-libaom --enable-avisynth --enable-chromaprint --enable-libdav1d --enable-libdavs2 --enable-libgme --enable-libmfx --enable-libkvazaar --enable-libmp3lame --enable-libilbc --enable-libvpx --enable-libmodplug --enable-version3 --enable-nonfree --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libvo-amrwbenc --enable-libfdk-aac --enable-libopenh264 --enable-libopenjpeg --enable-nvenc --enable-nvdec --enable-cuda --enable-cuvid --enable-libtwolame --enable-vapoursynth --enable-libwavpack --enable-libx264 --enable-libx265 --enable-libxavs --enable-libxavs2 --enable-gpl --enable-static --disable-shared




Output of configure script (pastebin)



Output of
uname -a
(in Msys)


MINGW64_NT-10.0-18362 <scrubbed> 3.1.4-340.x86_64 2020-05-22 08:28 UTC x86_64 Msys
</scrubbed>



The issue that I'm facing is that despite passing the options
--enable-static
and--disable-shared
, the executables generated still requirelibchromaprint.dll
,libfdk-aac-2.dll
, andlibgme.dll
to run. What I expected was that FFmpeg would execute independently of any DLL files since I passed those options to./configure
.
