The update broken the general usage: ./ffmpeg -loglevel info -re -i /root/bunny.mp4 -vcodec nvenc -preset hp -fflags +genpts -vb 24000k -minrate 24000k -maxrate 24000k -bufsize 48000k -muxrate 26000k -cbr 1 -2pass 0 -r 50 -g 100 -pix_fmt yuv420p - acodec aac -strict -2 -ac 2 -ar 48000 -ab 256k -flush_packets 0 - packetsize 188 -y -f mpegts out.ts ./ffmpeg -loglevel info -re -i /root/bunny.mp4 -vcodec nvenc_h265 - preset hp -fflags +genpts -vb 24000k -minrate 24000k -maxrate 24000k - bufsize 48000k -muxrate 26000k -cbr 1 -2pass 0 -r 50 -g 100 -pix_fmt yuv420p -acodec aac -strict -2 -ac 2 -ar 48000 -ab 256k -flush_packets 0 -packetsize 188 -y -f mpegts out.ts FFmpeg stucks, does not work for both. Before with nvenc work working fine with above commands. It looks like - g parameter, -muxrate, -flush_packtes stuck FFmpeg with this update. Below line works: ./ffmpeg -loglevel verbose -i /root/bunny.mp4 -vcodec nvenc_h265 -preset hp -r 50 -y -f mpegts out.ts _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
