MFX_ERR_UNDEFINED_BEHAVIOR returned by MFXVideoDECODE_DecodeFrameAsync function.


I've converted transcode_VM(D3D) sample from C++ to C language calling the C level APIs. I've used same session to save context of Encoder and Decoder. In the Transcoding loop, first call to the function MFXVideoDECODE_DecodeFrameAsync returns MFX_ERR_UNDEFINED_BEHAVIOR.

I'm using Windows 7 with D3D9 device acceleration. Can someone help me with the error code.

IDirect3D9Ex_CreateDeviceEx crashing: Memory voilation


I am trying to run Intel Media SDK Decoder with a C-only application-wrapper. I have used the tutorial-source-code from C++ simple_decode_d3d. Inside the CreateHWDevice() function, the IDirect3D9Ex_CreateDeviceEx() call is resulting in an "Access violation reading location 0x00000001" error. The same call pD3D9->CreateDeviceEx() in another C++ project, returns successfully. Is this behavior expected?

[SOLVED] gstreamer vaapi - connecting vaapipostproc with vaapiencoder_h264

Using Ubuntu Desktop 14.04 with gstreamer 1.3.1 and VAAPI 1.5.9-2 on an Intel NUC

I'm trying to use gstreamer + VAAPI to decode, scale and re-encode a video stream. VAAPI works fine, but I cannot get the vaapipostproc src to work with the vaapiencode_h264 sink.

does not like the negotiated frame rate: check_video_info: invalid framerate (0/1):

I am sorry to trouble you but I really need some help. Thank you very much!!
