I’m running an Xavier and have a time-lapse script running the following…
ffmpeg -f concat -i /media/nvidia/SCOUT/timelapse/concat.txt -y -r 30 -vcodec libx264 /media/nvidia/SCOUT/timelapse/cam3.mp4
I’ve just done some reading that I cannot use GPU in FFmpeg, does anyone know how I can achieve a similar output from Gstreamer?
Basically reading an input of image files from the concat file and then writing out to h264; but toooo slow on FFmpeg
Hi,
We have not supported hardware encoding in ffmpeg. It is under implementation. For hardware decoding, please check development guide.
Thanks, its my understanding GStreamer should be able to do it, but I just cant find a way of providing it an input type of concat

Tried the multifilesrc but it wants format of 0,1,2,3,4 , mine are in a date format specified in file /media/nvidia/SCOUT/timelapse/concat.txt
I can have it look at the directory rather than the file, but I need the images in the date format to do excluding of night times, weekends and bad weather days.

Hi,
Not sure how to run the gstreamer pipeline exact same as the ffmpeg command. Suggest you go to
http://gstreamer-devel.966125.n4.nabble.com/
Once you have a working pipeline, please replace software encoder with hardware encoder nvv4l2h264enc, to enable hardware acceleration.
