<div dir="auto">Hi all, I am attempting to use the KWIVER Docker image published <a href="https://hub.docker.com/r/kitware/kwiver/tags" target="_blank">here</a> to extract KLV meta data from the public VIRAT FMV data set hosted <a href="https://data.kitware.com/#collection/56f56db28d777f753209ba9f/folder/56f57fa48d777f753209c713" target="_blank">here</a>. I’m attempting to use the `kwiver dump-klv` command line tool with these videos but I am running into an issue where the ffmpeg video reader plugin isn’t found.<br>
<br>
Does anyone have tips on how to configure this Docker image so that `KWIVER_PLUGIN_PATH` is set and ffmpeg is available? Perhaps there is larger issue with the Docker image since `KWIVER_PLUGIN_PATH` is not set and `kwiver/build/bin` is not in the PATH on start?<br>
<br>
Here is the error I get when running `kwiver dump-klv 09152008flight2tape1_1.mpg” (<a href="https://data.kitware.com/#item/56f57fa48d777f753209c714" target="_blank">the first video</a> in that data folder):<br></div>
