driver ‘qcom-venus’ on card ‘Qualcomm Venus video encoder’ driver ‘qcom-venus’ on card ‘Qualcomm Venus video decoder’ So, I am expecting that ffmpeg can decode it at 25 fps using the HEVC accelerator.Īm I missing something in the command line or in the environment?īelow are the command and the ffmpeg -i AMP_D_Hisilicon_3_2160p_fps_25.265 -c:v hevc_v4l2m2m -f null out.nullįfmpeg version 3.4.7 Copyright (c) 2000-2019 the FFmpeg developersĬonfiguration: -enable-gpl -enable-nonfree -enable-static -disable-shared -enable-pthreads -enable-neon -enable-thumb -enable-optimizations -enable-hwaccel=v4l2

I tried a video sequence encoded at 25 Hz. However, when I try to decode a video sequence at 4K, ffmpeg is not able to decode in real-time, i.e., at the frame-rate at which the video is encoded. I tried an old version of ffmpeg (3.4.7).
