The picture structure in the output parameters from
MFXVideoDECODE_Query is set to MFX_PICSTRUCT_UNKNOWN for some codecs, so
the structure of the corresponding mfx surfaces created for decoding are
unknown. The pipeline will be broken when these surfaces are used as the
input for msdkvpp.
Example pipeline:
gst-launch-1.0 filesrc location=input_vp8.webm ! matroskademux !
msdkvp8dec ! msdkvpp ! fakesink
Error message:
0:00:00.031568911 14259 0x55b79dc684a0 ERROR msdkvpp
gstmsdkvpp.c:728:gst_msdkvpp_transform:<msdkvpp0> MSDK Failed to do VPP
ERROR: from element
/GstPipeline:pipeline0/GstMatroskaDemux:matroskademux0: Internal data
stream error.
This is a workaround for the above issue
# gst-msdk
gst-msdk is a plugin for
[Intel Media SDK](https://software.intel.com/en-us/media-sdk), a
cross-platform API for developing media applications. The plugin has
multiple elements for video hardware encoding leveraging latest Intel
processors through Intel Media SDK.
- MPEG2 encoding (*msdkmpeg2enc*)
- H.264 encoding (*msdkh264enc*)
- H.265 encoding (*msdkh265enc*)
- VP8 encoding (*msdkvp8enc*)
It requires:
- Intel Media SDK
# Giving it a try
Encoding a simple video test source and saving it to a file.
$ gst-launch-1.0 videotestsrc ! msdkh264enc ! filesink location=test.h264
