islandora Video module simplified installation

In an attempt to simplify video module installation I tried this :

START===================================================
sudo apt-add-repository ppa:archivematica/externals
sudo apt-get update
sudo apt-get install ffmpeg

download and install Islandora video.js module
https://github.com/Islandora/islandora_videojs/archive/7.x-1.6.zip
NOTE: I installed as module rather than as library.

download and install Islandora Solution Pack Video
https://github.com/islandora/islandora_solution_pack_video/archive/7.x-1.6.zip

Configure Video solution pack as follows:
Viewer - select video.js player
Keep original files after ingest - Checked
Path to ffmpeg executable /usr/bin/ffmpeg
Create .mkv derivative - Checked
Create display MP4 locally - Checked
MP4 audio codec - aac (not libfaac)
Create OGG locally - Checked
Path to Theora executable - ffmpeg2Theora (leave default)
Create thumbnail locally - Checked
Play OBJ datastream if MP4 is not present - Checked
Maximum files size for playing OBJ 500 MB

Specify in /etc/php5/apache2/php.ini (values can vary by setup)
upload_max_filesize=250M
post_max_size=250M
memory_limit=512M

sudo service apache2 reload
sudo service apache2 restart
END=====================================================

This works for me. The only issue is that it creates an error log "video.js not found" - presumably because the video module is looking for it in the /libraries folder. My guess that it might be easier to fix this than to keep the long and complicated video module installation as it currently stands.
Video module tests all pass except two items in .ogg derivative creation. I can live with this.

I am submitting this for your review. As I am not a developer I do not know what/if any repercussions this module installation method may have.

Thanks
