Using Hardware Accelerated Encoding (CUDA) with Dynamic MP4

[rfraedrich]

I like to utilize an RTX 3090 on a virtualized Encoder instance and need to customize the encoding parameters. Otherwise than MP4 Low, SD & HD the dynamic encoding seems to have the command prefix "ffmpeg -i {$pathFileName}..." somehow "hardcoded".

In order to get hardware encoding to work, i need to place "-hwaccel cuda -hwaccel_output_format cuda" inbetween ffmpeg and -i so that my string will look something like this:

ffmpeg -hwaccel cuda -hwaccel_output_format cuda -i {$pathFileName} -vf scale_npp=-2:{$resolution} -c:a copy -c:v h264_nvenc -b:v 8M -y {$destinationFile}

Where can i modify this? Thanks in advance.

Check this ...

add this in your videos/configuration.php file

$global['ffmpeg'] = 'ffmpeg -hwaccel cuda -hwaccel_output_format cuda ';

@DanielnetoDotCom Actually the variable $global['ffmpeg'] is missing from the documentation page you have linked, or it's misleading? To my understanding, it's only to point to the executable location, and not to customize the encoder ffmpeg command line attributes.

$global['ffmpeg'] = '/usr/bin/ffmpeg'; // Location of the FFMPEG executable

you can add some custom parameters like hardware acceleration , for example

$global['ffmpeg'] = '/usr/bin/ffmpeg -hwaccel cuvid ';
