  • ffmpeg, lower fps with gpu - too many packets buffered

    29 mai 2020, par Alter

    I'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.

  • Attempting to compile FFmpeg 4.2.3 statically for Windows 10 (x86_64), but binaries asks for missing DLLs

    29 mai 2020, par Expectator

    I 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&#xA;</scrubbed>

    &#xA;&#xA;

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