Jamroom upload stuck at 512M
Installation and Configuration
For being 38% of the size of your mp4 video (240mb versus 617mb), the JR version looks really good, and is certainly "HD" - it's resolution is 1280x720, the same as the MP4 version. To be frank I think 99% of internet users would be happy with the JR version.
Now that doesn't mean we can't make things work better for you

What I think we need to do is find a way to allow you to enter your own custom FFMpeg command line - that way you have 100% control over how the video gets converted.
You can already override the ffmpeg binary that Jamroom uses by adding a line to your data/config/config.php file:
$_conf['jrCore_ffmpeg_binary'] = '/usr/local/bin/ffmpeg';
I do this on my Mac. That way you can custom compile your own ffmpeg with the features and switches that you feel are important to you.
I think the "default" setup for JR video right now is pretty good and meets the majority of our user's needs, as again the most important aspect is disk space utilization. But I will get a ticket open to look at expanding the customization capabilities of the module.
Thanks!
