Encoder.cpp:81 Failed to get cpu core number from /proc/cpuinfo! !

[ForgetMe17]

Hi, i haved built the OMAF-SAMPLE on docker, while i am running the ffmpeg by
[root@cd2f2e35c575 Sample-Videos]# ./run.sh 4K VOD

I got the following errors, it seems that the encoder cannot get the /proc/info, but i was already in the root mode, and by running cat /proc/cpuinfo, i could get the output correctly.

Error initializing output stream 0:1 -- Error while opening encoder for output stream #0:1 - maybe incorrect parameters such as bit_rate, rate, width or height

Any help on this issue will be appriciated.

Hi @ForgetMe17 , can you provide the output of following command in the same environment that your error occurred?

cat /proc/cpuinfo | grep 'cpu cores' | cut -d ':' -f 2 | xargs | sed -e 's/\ /+/g' | bc

Hi @U1X6WK here is my output

[root@10b13c7e783a Sample-Videos]# cat /proc/cpuinfo | grep 'cpu cores' | cut -d ':' -f 2 | xargs | sed -e 's/\ /+/g' | bc

By the way, i am using ubuntu 18.04LTS on a virtual machine, and running the following command, where immersive_server:v1.4 was already built by the instructions in OMAF-Sample/README.md

    docker run --privileged -p 30001:443 -p 30002:8080 -it immersive_server:v1.4 bash  # Map the port.
    cd /usr/local/nginx/conf/
    ./configure.sh CN Shanghai A B C D [email protected]                                     # './configure.sh -h' for details.
    /usr/local/nginx/sbin/nginx                                                    # Start nginx.
    cd /home/immersive/Sample-Videos && ./run.sh <RES> <TYPE>                      # <RES>:[4K,8K] <TYPE>:[LIVE,VOD]

Please notice that we only verified the solution using software and hardware listed in OMAF-Sample/README.md.
Sorry to say that computing resources is way too few and OS of server doesn't match.

and here is the output of the cat command above
