Hardware acceleration support needed with Gstreamer on NVIDEA GPU

[Shrishty Deorari]

Hi All,

I am trying to build VDPAU GStreamer plugins which as I understand are supported inside gst-plugins-bad.  I have following system configuration:

System :   16.04 Ubuntu , 64 bit

Gstreamer: 1.4.5

GPU card and Driver: GeForce GTX 750 Ti, Driver Version: 384.59

The issue is after installing drivers for GPU card and building Gstreamer from scratch (all modules one by one) I built gst-plugins-bad but I see only one vdpau plugin through  gst-inspect-1.0 command.

 ./gst-inspect-1.0 | grep  vdpau
vdpau:  vdpaumpegdec: VDPAU Mpeg Decode

No Other plugins are built or found.

Debugging further I tried enabling hardware accelerations and vdpau while configuring gstliav using following options. 

--enable-vdpau --enable-hwaccels"

On doing so I can see :
Enabled hwaccels:
h263_vdpau        mpeg2_vdpau        vc1_vdpau
h264_vdpau        mpeg4_vdpau        wmv3_vdpau
mpeg1_vdpau

BUt Still, there are no other plugins available for h264 encoding and decoding of VDPAU.

Does the GPU card Which I am using doesn't have this support? Anyone with any clue on this?

"supported" is a bit of an exaggeration. Those elements were barely
ported. As you notice, only MPEG 2 Video decoder is in there. The
interest for supporting this API has remain extremely low, the porting
has not moved ever since. The interest is even lower that that NVidia
has moved to a different API for it's newest HW.

Yes, nothing else has been ported.

Feel free to complete the porting. Other options, which is also
slightly un-maintained on VAAPI side, is to use VDPAU VAAPI driver.

Please note this a very old version of GStreamer. Unsupported nowadays.

That's because it's the only vdpau decoder implemented in GStreamer. Still,
it is unmaintained, AFAIK.

Hardware accelerated decoders in libva are not wrappable in GStreamer.

Nowadays, VDPAU is considered deprecated and superseded by NVDEC, and GStreamer
has already an implementation of it, though I don't know if your card supports
it.

To add to the other replies, the VDPAU API is not supported by NVIDIA
anymore and NVENC/NVDEC are the new APIs. Both are supported by
GStreamer nowadays.

Thanks for the clarification. I was able to compile NVENC plugins on gst-plugins-bad-1.8.0.

Is there NVDEC also available on further Gstreamer  versions?

It's in no release yet, but you can get it from GIT master. NVENC also
got various improvements since 1.8
