[Kwiver-users] KWIVER Docker Usage: KWIVER_PLUGIN_PATH

[Bane Sullivan]

Hi all, I am attempting to use the KWIVER Docker image published here to extract KLV meta data from the public VIRAT FMV data set hosted here. 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.

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?

Here is the error I get when running `kwiver dump-klv 09152008flight2tape1_1.mpg” (the first video in that data folder):
