Hi all,
Few questions regarding video quality.
1. I have edited functions.inc.php line 169 to amend it to look like this....
$sTmpl = $sFfmpegPath . " -y -i " . $sInputFile . " -r " . getVideoFps() . " -s " . getVideoSize($sSize) . $sSound . " -qmin 1 -qmax 1 ";
I kept qmin and qmax both at 1 to indicated maximum quality conversion. I also uncheck "save video original quality while converting" and set Recording FPS to 25, and Recording Quality to 100 in the administration panel > modules > Flash Apps > Video Player > Settings
So I believe this should produce a decent video, the results....
Original .avi file = 4.7 MB screenshot below
Dolphin 7 converted the original to flv = 3.61 MB screenshot below
As you can see there is a huge quality difference, so I go and have a look at the error logs
under /public_html/flash/modules/video/inc
error_log reads

again i still am not sure what this entirely means, arvixe is my hosting so there should not be any issues with ffmpeg or php or shouldnt be any errors at all because they support d7 100%
With the quality being of such huge difference and the file size of small difference I wish i could just embed the original avi file and skip D7 doing the conversions and let me do them on my desktop. Maybe there is a way of doing that?
Next question... with the 2 images above... would this be a normal conversion loss or does it look like something is seriously wrong.
I have tried variations of the qmin qmax and without it completely, and having the setting in admin panel on max. This is the absolute best result i could produce up to this point.
The uploads and conversions and crons are all working just the quality is lacking for me and need to get it a bit better for tutorials that I make.
Any suggestions would be simply fantastic, I really like Dolphin 7 and the community has be great. I enjoy the software very much, i just need it a tiny bit better :)
