H.264 QuickSync Encoding Pitch

[idata]

I'm currently experience an issue on the i7-6920hq that I haven't experienced on the i7-4770.

I'm using QuickSync to encode an image to h.264 to be sent out via UDP in a mpeg transport stream. I'm currently using VLC to receive, decode, and display the video.

The issue is that the decoded image from the i7-6920 appears to have the correct resolution in VLC but the image pitch (# of pixels in a row) isn't correct, visually.

The i7-4770 with the same software works correctly.

The driver versions are the following:

i7-6920hq -> 20.19.15.4483 (Intel HD Graphics 530)

i7-4770 -> 09.18.10.3220 (Intel HD Graphics 4600)

I'm wondering if you know of anything that might cause my issue?

The driver you linked me to wouldn't install. Perhaps the SSU's output will help with that.We ended up installing the 20.19.15.4531 driver (found it on Dell's website for the chipset).

For the attachments:

The left image is what it is encoded and the right image is what is received. The encoder and streamer was written using the Intel Media SDK with the sample_encode application as a reference.

I have VLC version 2.0.5 for the client side.

I don't see the image in my attachments. So, I'll try again.

Hello Michael,

Thank you for the information provided!I noticed that you also have a NVIDIA Quadro M5000M 4GB installed on the system!It would be great to check if one of the GPUs in the unit is triggering the issue (Intel HD Graphics 530 or NVIDIA Quadro M5000M)For that reason, please perform the next tests.1. Disable the Intel HD Graphics 530 GPU, this can be done in the device manager, find display adapters then right click Intel GPU and hit "Disable"2. Check if the problem is still present, once you restarted the system.3. Do the same but disabling the NVIDIA Quadro M5000MAdditionally, related to the drivers, did you try the steps noted above?Hope I can hear from you with the results.Regards,Esteban C
