Please provide a solution and asap to include parameter in psz_cqm_file=8-0-8. Does that mean you have a file named "8-0-8”? In that case maybe try replacing the parameter with cqmfile

As Ted pointed out, that probably needed to be a file name. Nevertheless, kindly show us the actual working ffmpeg-2.6 command line. As far as I can tell, psz_cqm_file was never an ffmpeg option. It may have been an x264 option, which is now called cqmfile in the command line tool. You can pass that option from ffmpeg using "-x264opts cqmfile=filename". Cheers, Moritz
Dear Sir, As referred by Moritz below command is working fine for FFmpeg 4.1 -x264opts cqmfile=filename I would like to know the difference between psz_cqm_file and cqmfile.
From notes I got
/* JM format reads the external quantization matrix file in JM format, automatically ignores other -cqm option */ uint8_t cqm_4iy[16]; /* used only if i_cqm_preset == X264_CQM_CUSTOM */ uint8_t cqm_4ic[16]; Thanks Regards Abhishek Punjabi On Mon, Jul 15, 2019 at 8:54 PM Moritz Barsnick <barsnick@gmx.net> wrote:

This is more of an x264 question than an ffmpeg one, but if I were to guess they changed the parameter name at some point because, like, what does psz_cqm_file even stand for, right?
