The numerator and denominator are inversed.
For example, when the picture rate of a video signal is 25 fps, vps_time_scale may be equal to 27 000 000 and vps_num_units_in_tick may be equal to 1 080 000. in current implementation it will create a "0.04" fps stream.

Hi,

I do not see a parameter to make an interlaced HEVC encoding (1080i29.97). For example, I could generate interlaced HEVC encoding with x265 with below command. What would be a command for SVT? SVT sample application has a parameter ("-interlaced-video") to signal interlaced video though.

Parameter for x265:
-x265-params interlace=1

When transcoding 4KP60 10bit HEVC source (80M) to 16M, 20M, it doesn't generate output file. My script is like this.

ffmpeg_4.1_svt-hevc -loglevel info -r 60 -i input.ts -c:v libsvt_hevc -tune subjective -rc vbr -profile:v main10 -level 5.1 -b:v 16M -bufsize 32M -maxrate 16M -preset 11 -g 120 -y -f mpegts out.ts

Result is core dumped with Out of bound maxBufferSize for level 5.1 and tier 0. When set bufsize same as bit rate, result is still the same. Not setting bufsize, maxrate doesn't help either.

Moscow State University is soon (deadline March 1) starting with it's yearly codec review, it would be great to have SVT-HEVC included in it.

• MSU Annual Video Codecs Comparison 2019: Call for codecs

Dear.
Today I heard SVT-HEVC support RC mode for OQ (-tune 1) so I tried to test ffmpeg plugin for libsvthevc. there is no issues with RC mode for SQ (-tune 0)
However I showed below error message.
./ffmpeg -y -i ./nvme.mp4 -c:v libsvt_hevc -tune 1 -rc 1 -preset 10 -b:v 6M -r 30 -c:a aac -b:a 192k -tag:v hvc1 -f mp4 ./nvme_h265_1.mp4

Thank you

Is this supported on macOS?

As far as I could find out the Mac Pro uses Xeon processors...

Hi, could you please provide static target for libSvtHevcEnc? It's easier for deploying.
I have tried to manually fix Source/Lib/Codec/CMakeLists.txt but then its failed to Built target SvtHevcEncSimpleApp:

I tried to encode in the fastest mode for 4K 10bit sequence, like Netflix_FoodMarket2. There seems to have some bugs in the encoded bit-stream which made the ffmpeg decoder to output wrong images in the bottom rows in some frames.

The sequence could be downloaded from here:
https://media.xiph.org/video/derf/
And I used ffmpeg to convert it from y4m to yuv420p10 format.

The decoding image and bit-stream is public here.

Hi,
Parameter "-vid-info" doesn't take effect while do encoding with SVT-HEVC.

• Try to use SVT-HEVC version v1.2.0 to encode HEVC bitstreams with parameter "-vid-info" equals to 0 or 1, then use tools to check generated HEVC bitstreams, the value of "vps_timing_info_present_flag" always is 0.
• Try to use SVT-HEVC version v1.3.0 to encode HEVC bitstreams with parameter "-vid-info" equals to 0 or 1, then use tools to check generated HEVC bitstreams, the value of "vps_timing_info_present_flag" always is 1.

The encode command line we used as below: (take v1.3.0 app as example)

Such as 59.94 fps:
./ffmpeg -i XXX (a 59.94 fps stream) -c:v libsvt_hevc svt.265

After apply the FFmpeg plugin patch to FFmpeg, then run the transcode with the command:

./ffmpeg -i ~/Videos/skyfall2-trailer.mp4 -an -c:v libsvt_hevc test_svt.mp4

get the message like:

[mp4 @ 0x556f3d808940] Timestamps are unset in a packet for stream 0. This is deprecated and will stop working in the future. Fix your code to set the timestamps properly
[mp4 @ 0x556f3d808940] Encoder did not produce proper pts, making some up.

I think the plugin didn't handle the DTS/PTS.

Could you give a config item like --threads or give a theoretical boundary about the cores?I don't know how many physical cores is suitable to svt-hevc。

Question is on ffmpeg plugin. Is it on by default if it runs on skylake? Is there any way to disable AVX512 instruction for SVT HEVC encoder?

SVT-HEVC with the commit "43eb2e332b61a43f5d088e6d8be286f03eda43b8"

Hi, could you please provide static target for libSvtHevcEnc? It's easier for deploying.

Try this command:
./ffmpeg -i 4k-in.mp4 -c:v libsvt_hevc -preset <10/9/8..> -tune 1 -rc 0 -qp 31 4k-out.mp4
There would be one frame less in 4k-out.mp4 than 4k-in.mp4.

But if the input is *.264 file, seems no frame drop.

As title
An example call could be:
ffmpeg.exe -i "%~dpn1.avs" -f rawvideo -an -| ebHevcEncApp.exe -w 1920 -h 1080 -rc 0 -qp 26 -fps-num 24000 -fps-denom 1001 -i - -b "%~dpn1.hevc"

How to show PSNR of the video sequences after compression?
By ffmpeg on reconstructive sequences?

hi, my enviroment is centos6.9, when running build.sh, show the following info which failed to get the executable file. Could anyone have a look, thanks!

An user guide in markdown would be much easier to maintain.

• Upload original user guide (.docx I think?)
• Convert user guide to Markdown (using word-to-markdown and/or Pandoc for example).
• Check Markdown file on errors
• Upload to user guide in Markdown GitHub

When running "build.sh", CMake returns an error message and stops.
And no, using MSVC is not a proper solution — actually it's not a solution at all.

I try to test the program, but it exit directly without any error msg and output bitstream is 0B.

Then I trace the code, and find that CheckXcr0Zmm exit it,

int CheckXcr0Zmm() 
{
    uint32_t xcr0;
    uint32_t zmm_ymm_xmm = (7 << 5) | (1 << 2) | (1 << 1);
#if defined(_MSC_VER)
    xcr0 = (uint32_t)_xgetbv(0);  /* min VS2010 SP1 compiler is required */
#else
    printf("[%s-%d]\n", __func__, __LINE__);
    __asm__ ("xgetbv" : "=a" (xcr0) : "c" (0) : "%edx" );  // program exit here at once
    printf("[%s-%d]\n", __func__, __LINE__);
#endif

    return ((xcr0 & zmm_ymm_xmm) == zmm_ymm_xmm); /* check if xmm, ymm and zmm state are enabled in XCR0 */
}

I mark CheckXcr0Zmm function, and the program test OK.

Is there any problem for mark this code?

Have you got any plans for it?
Anyway can you help to configure it in current version of plugin?

Dear,
When we use the SVT-HEVC App with version v1.3.0 which is from Github Master (https://github.com/intel/SVT-HEVC.git) to do encoding with below command, and then measuring PSNR/SSIM using ffmpeg, comparing a bitstream to input yuv, found there is PSNR/SSIM mismatch issue.

- Do encoding with SVT-HEVC app:

- Measure PSNR/SSIM using FFMPEG:

Thanks and waiting for your feedback.

Encoding 100 NV12 format frames with VBR mode with cmd:

then use ffplay check test.h265, found the context is wrong.

the commit dc6c637 (mainline/master)

But YUV420P is Ok for this case.

So, is it have plan to support other input pixel format for nv12 or other format ?

Using encMode12 to encode a 10bit 4K 422bit stream.

While using FFMPEG with SVT-HEVC plugin, -preset 10 doesn't work for objective VQ mode. Based on the readme document, 1080p should support upto encMode 10 for both tune 0 and tune 1.
below is the command I am using:
/ffmpeg -i <input.mp4> -c:v libsvt_hevc -tune 1 -preset 10 out.mp4

[libsvt_hevc @ 0x40110c0] Error setting encoder parameters
*** Error in `./ffmpeg': free(): invalid pointer: 0x0000000004afcdd0 ***

I encode a 4K video by setting the frame rate and the number of frames as follows:

ffmpeg -i "input" -nostdin -f rawvideo -pix_fmt yuv420p - | ./HevcEncoderApp -i stdin -fps 30 -n 60 -w 3840 -h 2048 -b output.bin

The encoder finishes successfully and according to the summary at the end, 60 frames are encoded and the frame rate is 30fps:

SUMMARY --------------------------------- Channel 1 --------------------------------
Total Frames Frame Rate Byte Count Bitrate
60 30.00 fps 963170 3852.68 kbps

However, when I check the frame rate of the output binary video (ffprobe), I get 25fps. The duration and the bit-rate of the output video cannot be estimated because of "missing picture in access unit". I tested the encoder with different videos (in terms of resolution and frame rate) and the software always produces output videos with 25fps.

I run the encoder on Ubuntu 16.04 with 2 cores.

Try this command:
ffmpeg -i <720p input>.264 -c:v libsvt_hevc -preset 10 -tune 1 -rc 0 -qp 31 output.265, make sure it's "preset 10" which is not valid for 720p input.

Set latency-mode 1 will reduce the speed a lot.

Hi,

I followed the ffmpeg plugin build instruction on https://github.com/intel/SVT-HEVC/blob/master/ffmpeg_plugin/README.txt but it failed as shown below. How can this be fixed?

The library crashes with the following command line:
SvtHevcEncApp -i SlideShow_1280x720_20.yuv -w 1280 -h 720 -tune 1 -encMode 8

The crash is due to this secondSearchRegionIndexPosInteg going out of range.

cmd: ../bin/HevcEncoderApp -c ../bin/Sample.cfg -i clip2_540x960_25_org.yuv -w 540 -h 960 -n 200 -rc 0 -q 26 -fps 25 -b test_new.265，result is distorted like the following：

source file and output test_new.265 can download from https://pan.baidu.com/s/1jEBzesyQ4-FEjyhITjvexA

Using HM to decode the encoded bitstream, will assert(if you turn it on) at checking for rtsp_stop_one_bit in VPS

Hi,

I used the tool on "Ubuntu" to encode a 2K/HDR video with the following command:

sudo HevcEncoderApp -i input.raw -b ouput.265 -w 1920 -h 1080 -fps 23.976 -bit-depth 10 -tune 0 -rc 1 -tbr 15000000 -encMode 0 -level 6.2 -tier 1

The encoding was finished; however, a lot of artifacts appears when playing the output 265 file with different players.

There are lots of bad blocks and noises here and there in the frames and the artifacts come to its peak especially when there is a big scene difference. Would you mind taking a look at the command and providing some feedback on how to fix it?

Also, processing a 4K video tends to freeze the machine (4 cores). Is there a way to specify number of cores to be used?

Thanks a lot!

EbInitEncoder takes too much time(1.8s) on Ubuntu16.04 v1.3.0 Xeon-E5.
After some debug, parsing /proc/cpuinfo costs most of time(1.3s). Because E5 has 72 cores ,and big cpuinfo file.

e5-cpuinfo.txt

An example of the encoding command line is as follows:
"D:\Encoder\FFMPEG\ffmpeg.exe" -loglevel level+error -i "%~dpn1.mp4" -pix_fmt p010le -strict -1 -f rawvideo -nostdin - | "D:\Encoder\SVT-HEVC\SvtHevcEncApp" -i stdin -encMode 9 -tune 0 -w 1920 -h 1080 -bit-depth 10 -profile 2 -fps-num 24000 -fps-denom 1001 -q 30 -n 300 -b "%~dpn1_SVT-HEVC.hevc"

You can use any H.264 video file encoding to reproduce the problem.

@lijing0010 could update README, user guide, sample config file accordingly?
