[FFmpeg-user] concatenating files in FFMPEG causing the wrong file length

[andrei ka]

fyi, this is example of ffmpeg docker file with gpu encoding capabilities :
https://hub.docker.com/r/jrottenberg/ffmpeg/dockerfile
you take it, mod it for taking 4.1.2 ( FFMPEG_VERSION=4.2.1) , and make
patch mod in docker file

DIR=/tmp/ffmpeg && mkdir -p ${DIR} && cd ${DIR} && \
        ./configure \

DIR=/tmp/ffmpeg && mkdir -p ${DIR} && cd ${DIR} && \
patch -p1  --ignore-whitespace <  /tmp/patch.txt && \
./configure \

and you fire:

docker build --tag ffmpeg:4.2.1.dts .

and you should be fine...
