Hi guys,
I am getting error while doing encoding of yuv video to h264 format. Please suggest any changes for the following command but I was using the same command previously and it was working fine. I updated ffmpeg recently I am not sure if that affected it. Command and error is as following-
ffmpeg$ ffmpeg -y -s 720x480 -b 256k -r 30 -f rawvideo -i akiyo_720x480.yuv -pass 1 -vcodec libx264 -y -b 256k -r 30 -preset fast -g 10 -s 720x480 -coder 1 -flags +loop -cmp +chroma -flags2 -fastpskip -partitions +parti4x4+partp8x8+partb8x8+parti8x8+partp4x4 -chromaoffset 0 -b_qfactor 0.45 -flags2 +wpred -subq 8 -flags2 +mixed_refs -flags2 +dct8x8 -me_range 16 -me_method umh -keyint_min 10 -sc_threshold 40 -trellis 2 -i_qfactor 0.71 -qcomp 0.5 -rc_eq 'blurCplx^(1-qComp)' -level 40 -bf 16 -b_strategy 1 -flags2 +bpyramid -bidir_refine 1 -refs 6 -cqp 28 -qmin 8 -qmax 48 - f -deblockalpha 0 -f h264 -deblockbeta 0 -threads 0 output.264
