HEVC Quality

I am doing some experiments with HEVC encoding. I'd like to confirm some things about HEVC encoding with driver version 20.19.15.4474 on a Core-i7 6700K (Skylake) CPU with hardware 1.19 API. I am doing sweeps of various settings and looking at PSNR vs actual (as opposed to requested) bitrate. I am charting the results and calling them "PSNR curves". The sample video I am using is "Samsung Earth From Above" 1080p/29.97. Right now I am just trying to determine if I have bugs in my code that are affecting the results.

Here are my questions about HEVC:
    1) Are the speed-quality settings grouped like (1,2), (3,4,5), (6,7) such that the values in each group are identical to each other?
    2) Are AVBR, VBR, ICQ, and CQP all the supported rate control methods?
    3) In my results AVBR and VBR give relatively close PSNR curves, and likewise with ICQ and CQP. Is it reasonable that AVBR/VBR have significantly higher (better) PSNR curves than ICQ/CQP?

Memory leak in H264 decoder on i7-6770 systems?

October 1, 2016, 5:17 am

i7-6770/8GB RAM in an Intel Skull Canyon NUC running Windows 10 Pro with the 20.1915.4501 driver package. The Media SDK is 2016_R2.

We runnnig code based on the simple_decoder example contained in the Media SDK tutorials: https://software.intel.com/en-us/articles/media-sdk-tutorials-for-client-and-server. The sample has been modified so that it loops over the raw H264 bitstream (thus acting as a continuous test source) and it outputs BGRA. 

On all of the other systems we have here (gen 3,4, 5 and 6 with i5, i7 and Z8350 processors), running both Windows 7 and Windows 10, this code works exactly as expected.

On the 6770, the working set delta (as reported by task manager) is somewhere between 1400K and 2000K per task manager update.

By way of a sanity check we also run a stock build of the sample_decode example. When using the same H264 bitstream file in render mode this application does not exhibit any symptoms of a memory leak.

This is a show stopper for us. [edit] I have attached a complete VS2013/2015 project that demonstrates the issue quite clearly. I hope will help isolate the problem. Any help greatly appreciated!

Many thanks

As described in subject field, the h264 feed, that has motion_vectors_over_pic_boundaries_flag set to 1 in sps header sequence is decoded to huge artefacted green screen. Both in my project and provided decode_sample example.

Feed used is received from Microsoft Media Foundation encoder on WIndows 8 and 10 or from ffmpeg with default 264 presets.

All the returns are MFX_ERR_NONE and no warnings are being received throughout initialization, header decoding and frame decoding processes.

Seeking on ffmpeg hevc_qsv video

October 5, 2016, 3:47 pm

Hi All,

I'm having some playback issues when using ffmpeg and hevc_qsv codec.  The video seems to convert fine, but playback has problems.  When seeking in the video, e.g. clicking on the timeline bar in VLC, potplayer,  or other player, the video takes a long time to seek.  It takes about 10 seconds or so to seek.  Once it starts playing again (after 10 seconds) it plays at twice the speed, like it is catching up.  On Potplayer, it will also not display the preview thumbnails.  Playing on VLC, it doesn't seek at all, it just stays in the same spot.  

I have compiled most recent ffmpeg from scratch on Centos 7.2 using the newest 2017 SDK.  I'm converting on a skylake cpu.  

Converting with h264_qsv or libx265 the files are fine.

Using a simple command line:

/usr/local/bin/ffmpeg -ss 1437.664 -i /temp/lethal.mkv  -c:v hevc_qsv -q 20 -load_plugins 6fadc791a0c2eb479ab6dcd5ea9da347 /temp/lethal-conv.mkv

I have uploaded an example file, but had to change the extension to mp3 to upload.  So, change the extension back to mkv.   I'm not sure if this is an ffmpeg problem or sdk problem.

Hi

I tried to decode AAC/LATM mpeg-ts stream type 0x11) stream with the audio decoder but got MFX_ERR_NOT_SUPPORTED.

AAC with ADTS header stream (mpeg-ts stream type 0xF) is working fine.

is there any way to make the decoder decode AAC/LATM stream?  

Thank you

I had modified the Android JAVA sample app to record in Portrait mode but the recorded video is upside down when recording with the front camera.  Recording with the back camera works fine.

 This is the function in the sample app that sets the orientation for the recording. 

How do I fix the orientation when recording?  Thanks

private void createPreview() {
        surfaceView = new GLSurfaceView(getApplicationContext());

        surfaceView.setDebugFlags(GLSurfaceView.DEBUG_CHECK_GL_ERROR);

        ((RelativeLayout) findViewById(R.id.camera_layout)).addView(surfaceView, 0);

        preview = capture.createPreview(surfaceView, camera);
        preview.setFillMode(fillMode);

        if (getRequestedOrientation() == ActivityInfo.SCREEN_ORIENTATION_PORTRAIT) {
            capture.setOrientation(90);

Device failure error while using mix memory type

October 18, 2016, 3:29 am

I am trying to setup the following chain for video processing.

VPP1 -> VPP2

where     VPP1Params.IOPattern =
        MFX_IOPATTERN_IN_SYSTEM_MEMORY | MFX_IOPATTERN_OUT_OPAQUE_MEMORY; and

              VPP2Params.IOPattern =
        MFX_IOPATTERN_OUT_OPAQUE_MEMORY | MFX_IOPATTERN_IN_SYSTEM_MEMORY;

I am using mfxExtOpaqueSurfaceAlloc for the opaque surface alloc information. Now the problem is, when the intel media sdk library implementation is SW based, I am getting correct output after second vpp session is finished. But when the implementation is HW based, program exits with status code -17 (MFX_ERR_DEVICE_FAILED) from MFXVideoVPP_RunFrameVPPAsync function . I am currently running intel media sdk version 1.17. 

In the release notes of version 1.19, it is stated in common feature that "Opaque memory usage extended to support external allocator in transcoding pipelines with mixed memory types. ". So, Opaque memory with mixed memory types is not supported prior to version 1.19? And if it is not the case, what might be the possible cause for the error?

We are working on Media sdk Gold configuration in which we are encoding Video from media SDK and encoding Audio from ffmpeg /avconv ..

after encoding completed successfully we want to mux these two "es" into mpeg TS .. but unfortunately we are having problem in muxing ..

initially we are trying to identify where encoded frames can be captured /passes in muxing function.

is there any sample or support for media sdk based muxing is available ? welcom for all suggestion having details for audio muxing in media sdk based encoder application .

we are supposed to use ffmpeg based muxing because we are already using ffmpeg to capture live data from capture card..

please suggest any solution

QuickSync get stuck after 2 reconfigurations

October 19, 2016, 11:25 pm

We have some strange issue with QuickSync encoder. During normal encoding we doing 2 reconfigurations (MFXVideoENCODE_Reset). After that, encoder stucks in following state:
1. All sync points completed (no active sync points).
2. 6 frames locked by quicksync, i.e. Locked = 1.
3. EncodeFrameAsync returns MFX_WRN_DEVICE_BUSY warning while trying to submit next frame or flush.
So in this state I can not submit next frame to encoder and there is nothing to read from encoder (bitstream).
 
We added detection for this case and restart encoder when this situation detected. And this works fine when I submit frames in video memory. But in case when buffers in system memory submitted, encoding ends in 8 locked frames and waiting in memory allocator for first available buffer to submit 9th frame. So app freezes in this state.
We using Intel Media SDK 2016 R2 (7.0.0.358). I have dump already with mentioned freeze and can provide it, and will also provide more info as soon as I get that from test team.
