Skylake HEVC transcoding

[rasko_N_]

Can i transcode to HEVC with Skylake E3-1275 or E3-1585 with Community version MSS 2017 R3 or need Proffesional MSS?

[Artem_S_Intel]

Yes you can transcode to HEVC using community addition and HW HEVC encoder.

Thanks so quickly answer to my request! So if  i do tests everything is ok. But when i try to transcode with ffmpeg and hevc_qsv i can not open this stream, get errors:

Could you help me 

[Artem_S_Intel]

can you attach your result?

Most likely you have some issue on ffmpeg side with muxing stream into container

[rasko_N_]

We transcoding using tee option of ffmpeg one udp live stream to two different bitrate and frame size  with overlayed logo, everything when transcoding looks nice!

By result I mean result transcoded file, that can't be played, if there are no any license restrictions with content.

[rasko_N_]

No license problem. We can played directly input sream on VLC or ffplay and can analyze it on ffprobe, no problem with source. Also we can transcode such input stream with HW h264_qsv without any problem, problem only with HEVC.

We can played directly input sream on VLC or ffplay and can analyze it on ffprobe, no problem with source. Also we can transcode such input stream with HW h264_qsv without any problem, problem only with HEVC.

sort of confusing messages with mix of everything inside - let's go step by step, please:

1. HEVC and AVC transcoding from ffmpeg with QSV works and does not produce error messages?

2. if VLC cannot play HEVC content only - can you show VLC's details, such as build and VLC log?

1. Works very well without any errors 

2. VLC (last version) can not play this stream, also i can provide information ftom ffprobe:

thanks for the confirmation of the encode.

about VLC , I believe it is the target - can you please run it as

vlc --verbose=2 --file-logging

(this will enable logging into vlc-log.txt file)

and try HEVC playback ?

you might want to share .txt log from vlc

[Maxym_D_Intel]

ok, VLC log does not seem to show any explicit problem related to the codec itself

so it might be muxing or network handling issue(s) as well.

I would recommend you to try VLC nightly build and if does not work, please ask for the help on VLC forum. 

[rasko_N_]

I see very strange things:

1) If before transcoding (via ffmpeg) open ffplayer (or another ffmpeg to play stream) first and restart transcoding on ffmpeg stream can be played normal. 

2) We can not use HLS segmenting for such hevc stream also. Why? for H264 no problem.

I think, this problem not a VLC problem.

[rasko_N_]

Dear Maxym 

I m find problem on segmenting stream with hevc_qsv to see problem could you on your side try one simple test?:

./ffmpeg -i udp://227.0.1.1:1001 -c:v hevc_qsv -load_plugin hevc_hw -pix_fmt nv12 -q 20 -profile:v 1 -preset medium -level:v 51 -b:v 2600k -g 90  -f segment -segment_time 5 -segment_list_type flat -segment_list stream.m3u8 -y -segment_format mpegts  stream%05d.ts

HEVC_QSV can not segmenting streams on ffmpeg

[Artem_S_Intel]

I suspect it is ffmpeg not segmenting streams with HEVC :). Can you try the same with x265? Most likely you'll see the same
