HDR10+ Profile A HEVC 10-bit 23.976 Sample (in MKV with DTS:X audio)




The ffmpeg command throw this error on every line, with the number always being 93 for multiple different output video codec


nb_cpb 93 invalid.0 q=0.0 size= 0kB time=00:00:00.65 bitrate= 0.5kbits/s speed=3.95x 



A search point to this source file https://github.com/FFmpeg/FFmpeg/blob/master/libavcodec/hevc_ps.c


if (!hdr->flags.low_delay_hrd_flag) {
 hdr->cpb_cnt_minus1[i] = get_ue_golomb_long(gb);
 if (hdr->cpb_cnt_minus1[i] > 31) {
 av_log(NULL, AV_LOG_ERROR, "nb_cpb %d invalid\n",
 hdr->cpb_cnt_minus1[i]);
 return AVERROR_INVALIDDATA;
 }
}



What went wrong ?


ffmpeg -i E:\HDR.mkv -c:v libx265 -c:a copy "HDR.mp4"

How to Play Smooth 4K Video with FFplay ? [closed]
14 mai 2020, par Matan MarcianoIm trying to play 4K video with ffplay and the video is not smooth.



Video File :



- 

- Big Buck Bunny, 4K, 60fps, 30Mbps
- http://distribution.bbb3d.renderfarming.net/video/mp4/bbb_sunflower_2160p_60fps_stereo_abl.mp4







Hardware :



- 

- Dell OptiPlex 7070 Micro (8 Cores, 8GB RAM, GPU : Intel Corporation UHD Graphics 630)
- Samsung U28E590D, 4K Screen
- DisplayPort to HDMI Cable









Software :



- 

- Ubuntu 19.04
- ffplay with libmvx (according this guide : https://github.com/Intel-Media-SDK/MediaSDK/wiki/Build-and-use-ffmpeg-with-MediaSDK)







The FFplay command I used is :
ffplay -vcodec h264_qsv -i input.ts



- 

- Notes :
- During the playing, my CPU usage is around 25% (according to 'top' command)
- FFplay logs indicate on many frame drops
- I also tried VLC and MPV player's- VLC looks bad also. MPV player looks better but still not smooth.











So, its looks like my hardware is good enough for 4K playing. What am I missing ?
How can I play smooth 4K video via FFplay ?
