Vybrid GStreamer Optimization

ierkiaga — Thu, 12 Feb 2015 15:43:47 GMT

Hi everybody,

Currently I'm workin in a design with a vybrid VF6XX (Quartz Development Kit) and I'm decoding H264 coded video with GStreamer. It works great when decodes small resolution videos but decoding is too slow when using fullscreen (800x500). I experienced this issue both when working with native 800x500 videos or reescaling lower resolution videos.

My GStream pipeline is the following one: gst-launch filesrc location=$1 ! qtdemux ! h264parse ! ffdec_h264 ! ffmpegcolorspace ! fbdevsink device=/dev/fb0

I know that this processor does not have any video decoding units and using software decoding libraries is so hard for the processor. However I would like to share my experience and ask if anyone has more expirence with Vybrid + GStreamer, and how I can improve de H264 decoding process.

Thanks

Ibai Erkiaga

timesyssupport can you attend this case?

Hello Ibai,

Unfortunately, without some kind of hardware accelerated decoding, h264 decode at higher resolution will lack performance.
