Hi, I'm using GPAC and mp4client on a PC to decode video but can I redirect the decoded video frame to an output video card/device like a BlackMagic card to send the video on a TV through an HDMI link.
Have an idea on how I could achieve that ?
Thanks, Alex.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
GPAC is modular. The output module is chosen at runtime among a list of available modules for your specific build, platform, etc..
The list of output modules available is in modules/. Look for names suffixed with '_out'.
The module actually used is listed in your GPAC configuration file (its location is displayed when launching MP4Client). In the [Video] section, DriverName value.
You can force the module you want to use when launching MP4Client with the '-opt' option.
To build an output module, implement the GF_VideoOutput interface. You can read more in include/gpac/modules/video_out.h .
Please ask if you have any question. Any contribution or feedback on the GPAC codebase is welcome.
