    Incorrect Video Orientation / Rotation

    Hi,

    I have been trying unsuccessfully to encode a video and keep its original orientation. Below is the code I am using with no luck. I have pulled this together from your samples and a few posts from this forum. Any guidance you could provide would be greatly appreciated.

    I have also attached a sample video file I have been testing with that was recorded on a Moto X (2nd gen) running Android 5.1 and what the output looks like.

    what are the meaning of intel_gpu_top information when encoding by qsv

    Hello!

             I use qsv to encoder 8 video streams ( mpegts udp --> h264 rtmp,  720P), and watch gpu usage by intel_gpu_top.  because we use msdk 1024 in our encoder product, so I can't use metrics_monitor in product. I googled but not found the meaning of intel_gpu_top output.  

              What are the meaning of  intel_gpu_top information: render, bitsteam, GAM, TSG, VFE, TDG?   Thanks very much !

    session independence and error_not_supported ..

    I'm currently having a problem and wonder if someone could shed a light on how to solve it. According to the docs: "Each SDK session can independently be a software-based session or hardwarebased session." which here unfortunately seems not to be the case. Basically the problems breaks down to an error MFX_ERR_UNSUPPORTED returned by a call to MFXInit (MFX_IMPL_HARDWARE_ANY) function under some special circumstances. These are as follows.

    MFXVideoCORE_SyncOperation failing with MFX_ERR_DEVICE_FAILED

    Hello,

    I'm using FFmpeg for my transcoding needs (to transcode multiple live streams) and I've been looking into a QSV-enabled encoder which was recently added there. I looked at the code and it's a fairly simplistic, basically something among the lines of:
