[WINDOWS] playbin: avdec_h264 used instead of mfx h264 decode #143

Closed boxerab closed 5 years ago

boxerab commented 5 years ago

I set the rank to be very high for mfx h264 decode, but playbin is still using avdec_h264. Is there another way of forcing gstreamer to us mfx plugin ?

boxerab commented 5 years ago

I have added the mfx dll to /lib/gstreamer-1.0 directory, and gst-inspect can find the mfx plugin, but when I add mfx to my pipeline, I get the error: no element mfx

"mfx" is the collection, container containing several specific plugins. Run "gst-inspect-1.0 mfx" and something like the following will be printed, actually listing the plugin names to be used in a pipeline: mfxh264dec: MFX H264 decoder mfxhevcdec: MFX HEVC decoder mfxmpeg2dec: MFX MPEG2 decoder mfxvc1dec: MFX VC1 decoder mfxvp8dec: MFX VP8 decoder mfxvp9dec: MFX VP9 decoder mfxjpegdec: MFX JPEG decoder mfxdecode: MFX Video Decoder mfxvpp: MFX video postprocessing mfxsinkelement: MFX sink mfxsink: MFX Sink Bin mfxh264enc: MFX H.264 encoder mfxhevcenc: MFX H.265 encoder mfxjpegenc: MFX JPEG encoder mfxvc1parse: VC1 parser

According to this issue's title you might want to use "mfxh264dec" in your pipeline.

Thanks, But, I don't see any of these plugins when I run gst-inspect

brmarkus commented 5 years ago

What do you see instead when running "gst-inspect-1.0 mfx"? Instead of copying the MFX DLL, can you do a "make" and "make install"? Not sure what else need to be installed and in place.

Also, when I build the INSTALL project, it installs into c:\lib\gstreamer-1.0 which is the wrong directory

Here is the output from gst-inspect:

c:\Users\aaron\src\gstreamer-media-SDK>gst-inspect-1.0 mfx Plugin Details: Name mfx Description MFX encoder/decoder/video post-processing plugins Filename C:\gstreamer\1.0\loki_x86_64\lib\gstreamer-1.0\gstmfx.dll Version 2.0.2 License LGPL Source module gst_mfx Binary package gst_mfx Origin URL http://www.intel.com

I have gstreamer in a non-standard location, btw

brmarkus commented 5 years ago

Ups, didn't know you were building under MS-Windows... If under Linux I could say something went wrong building the mfx plugins... your output of gst-inspect doesn't show anything but "0 features"...

boxerab commented 5 years ago

Perhaps the problem is issue #144

Yes it is indeed.
