Poor quality HEVC from nvenc
by Elliott Balsley 15 Dec '20

15 Dec '20

I am experimenting with hevc_nvenc and I am having trouble getting a high quality image with VBR mode. I tried giving it a super high bitrate of 100Mbps but this only encodes 29Mbps, which makes me think I am missing some important setting. How can I make it use more bits, and are there any other parameters I should try for better quality? I’m using Tesla T4. I tried B frame refs instead of weighted prediction but that didn’t make any difference and I believe you can’t use both at the same time. I’ve tried several different combinations of nvenc parameters, but I am not sure if I need to also adjust any ffmpeg options too. Here’s an example command. I can post before/after images if it helps. The main problem is blocky artifacts in the darker areas. $ ffmpeg -y -i ArriHD_short.mov -pix_fmt yuv444p16le -an -c:v hevc_nvenc -preset p7 -tune hq -profile:v main10 -rc vbr -rc-lookahead 24 -weighted_pred 1 -spatial-aq 1 -b:v 100M aq-weigh.mkv ffmpeg version N-100390-ge0e9c94c2b Copyright (c) 2000-2020 the FFmpeg developers built with gcc 7 (GCC) configuration: --enable-gpl --enable-nonfree --enable-nvenc --enable-libx264 --enable-libx265 --enable-libfdk_aac --enable-libopus --enable-libnpp --enable-cuda-nvcc --extra-cflags=-I/usr/local/cuda-10.2/targets/x86_64-linux/include --extra-ldflags=-L/usr/local/cuda-10.2/targets/x86_64-linux/lib libavutil 56. 62.100 / 56. 62.100 libavcodec 58.115.102 / 58.115.102 libavformat 58. 65.100 / 58. 65.100 libavdevice 58. 11.103 / 58. 11.103 libavfilter 7. 92.100 / 7. 92.100 libswscale 5. 8.100 / 5. 8.100 libswresample 3. 8.100 / 3. 8.100 libpostproc 55. 8.100 / 55. 8.100 Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'ArriHD_short.mov': Metadata: major_brand : qt minor_version : 537199360 compatible_brands: qt creation_time : 2020-12-10T22:41:31.000000Z Duration: 00:00:20.25, start: 0.000000, bitrate: 175506 kb/s Stream #0:0(eng): Video: prores (HQ) (apch / 0x68637061), yuv422p10le(tv, bt709, progressive), 1920x1080, 173968 kb/s, SAR 1:1 DAR 16:9, 24 fps, 24 tbr, 24 tbn, 24 tbc (default) Metadata: creation_time : 2020-12-10T22:41:31.000000Z handler_name : Apple Video Media Handler vendor_id : appl encoder : Apple ProRes 422 HQ timecode : 00:00:12:21 Stream #0:1(eng): Audio: pcm_s16le (sowt / 0x74776F73), 48000 Hz, stereo, s16, 1536 kb/s (default) Metadata: creation_time : 2020-12-10T22:41:31.000000Z handler_name : Apple Sound Media Handler vendor_id : [0][0][0][0] Stream #0:2(eng): Data: none (tmcd / 0x64636D74), 0 kb/s (default) Metadata: creation_time : 2020-12-10T22:41:31.000000Z handler_name : Time Code Media Handler reel_name : 01_NAB2017_ARRI_Camera_Showreel_Part01_UHD_WL_HDR10_24fps_stereo24bit timecode : 00:00:12:21 Stream mapping: Stream #0:0 -> #0:0 (prores (native) -> hevc (hevc_nvenc)) Press [q] to stop, [?] for help Output #0, matroska, to 'aq-weigh.mkv': Metadata: major_brand : qt minor_version : 537199360 compatible_brands: qt encoder : Lavf58.65.100 Stream #0:0(eng): Video: hevc (Rext), yuv444p16le(tv, bt709, progressive), 1920x1080 [SAR 1:1 DAR 16:9], q=2-31, 100000 kb/s, 24 fps, 1k tbn (default) Metadata: creation_time : 2020-12-10T22:41:31.000000Z handler_name : Apple Video Media Handler vendor_id : appl timecode : 00:00:12:21 encoder : Lavc58.115.102 hevc_nvenc Side data: cpb: bitrate max/min/avg: 0/0/100000000 buffer size: 200000000 vbv_delay: N/A frame= 486 fps= 88 q=14.0 Lsize= 72130kB time=00:00:20.20 bitrate=29238.8kbits/s speed=3.64x video:72125kB audio:0kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: 0.007138%

Public FFmpeg Docker images built with GitHub Actions
by Ryan Williams 14 Dec '20

14 Dec '20

Just wanted to mention this in case it's helpful to anyone: https://hub.docker.com/r/runsascoded/ffmpeg These are Docker images I've built and published (from source releases as well as a few misc Git commits) using GitHub Actions on a fork of the GitHub FFmpeg mirror: https://github.com/runsascoded/FFmpeg#readme If you have Docker installed, you can run ffmpeg without having to install it, e.g.: ``` $ docker run runsascoded/ffmpeg -version ffmpeg version 4.3.1 Copyright (c) 2000-2020 the FFmpeg developers … ``` Other versions are also available, e.g.: ``` $ docker run runsascoded/ffmpeg:4.2.4 -version ffmpeg version 4.2.4 Copyright (c) 2000-2020 the FFmpeg developers … ``` At the moment I've published images for 4.3.1 (which is also "latest"/default), 4.3, 4.2.4, and 4.1.6. The Dockerfile build commands I'm using fail on 4.0.6 and 3.4.8, and I haven't looked much at fixing them. It might be nice to publish images like this under ffmpeg/ffmpeg (I only see a coverity-related image with one "latest" tag not obviously tied to any specific release under https://hub.docker.com/u/ffmpeg currently). The GitHub Action workflow I used here is in principle upstream-able (`DOCKERHUB_USER` and `DOCKERHUB_TOKEN` "secrets" on the FFmpeg GitHub repo, as well as the presence of the .github/workflows/ci.yml file and docker/build.{sh,py} scripts, would cause GitHub to run on every commit and publish images tagged with every Git commit SHA, branch name, and tag), but seems incompatible with existing development/release workflows, so I assume it's not in the cards. Certainly anyone is welcome to take what I've done and upstream some or all of it. In the meantime I'll keep an eye out for new releases and push tags to trigger Docker image builds for them. The /issues page is also open on my fork in case I miss one: https://github.com/runsascoded/FFmpeg/issues Thanks, happy to hear others' thoughts on this. -Ryan

Video recording date with ffprobe
by Mar Andrés López 13 Dec '20

13 Dec '20

Dear all, I would like to extract the date in which my video was recorded. Now I am using the following ffprobe command: ffmpeg -i video.mp4 -v quiet -select_streams v:0 -show_entries stream_tags=creation_time -of default=noprint_wrappers=1:nokey=1 Which prints the creation_time and I guess that it is the datetime in which the file was created. But I want the time in which the video was recorded, should it be in the video metadata? Is that possible to retrieve this value with ffmpeg? A lot of thanks. P Please consider the environment before printing this e-mail.

nvenc and parallel process memory leaks?
by Paweł Bajorek 12 Dec '20

12 Dec '20

Hi, I have a problem with transcoding using nvenc. The problem is incresing memory consumption, it is about of hundreds kB/s. Im transcoding parallel exactly 74 streams to hls. After many hours some processes are killed by oom_killer. It can be restarted, but in this case i have less and less memory and so i cant restart it. oom_killer starts about 30 hours after start transcoding. im using newest version which is available from git for ffmpeg (sources), cuda version 11.02, and compiled with: pkg_config='pkg-config --static' --enable-nonfree --enable-cuda --extra-cflags=-I/root/ffmpeg/include --extra-ldflags=-L/root/ffmpeg/lib --enable-cuvid --enable-nvenc --extra-cflags=-I/usr/local/cuda/include --extra-ldflags=-L/usr/local/cuda/lib64 --enable-gpl --enable-libnpp --enable-libx264 --enable-libx265 --enable-libfdk-aac --enable-libopus --disable-pthreads on Ubuntu LTS 18.04 below is cmd im using: ffmpeg -vsync 1 -copytb 1 -analyzeduration 10000000 -probesize 10000000 -hwaccel cuvid -c:v h264_cuvid -hwaccel_device 0 -deint 1 -drop_second_field 1 -overrun_nonfatal 1 -fifo_size 713924 -buffer_size 67108864 -f mpegts -i "udp://239.254.2.217:6060"?timeout=5000000 -filter_complex "[0:v]split=outputs=4[map:v:0][v1][v2][v3];[v1]scale_npp=-1:720[map:v:1];[v2]scale_npp=-1:480[map:v:2];[v3]scale_npp=-1:360[map:v:3]" -map [map:v:0] -map [map:v:1] -map [map:v:2] -map [map:v:3] -map a:0 -map a:0 -map a:0 -map a:0 -ac 2 -ar 44100 -c:v:0 h264_nvenc -profile:v:0 baseline -c:v:1 h264_nvenc -b:v:1 3072k -maxrate:v:1 3072k -profile:v:1 baseline -c:v:2 h264_nvenc -b:v:2 1536k -maxrate:v:2 1536k -profile:v:2 baseline -c:v:3 h264_nvenc -b:v:3 300k -maxrate:v:3 300k -profile:v:3 baseline -c:a:0 libfdk_aac -b:a:0 128k -c:a:1 libfdk_aac -b:a:1 128k -c:a:2 libfdk_aac -b:a:2 64k -c:a:3 libfdk_aac -b:a:3 32k -metadata service_provider="SPI" -metadata service_name="Kino Polska HD" -max_muxing_queue_size 512 -flush_packets 1 -preset:v fast -gpu 0 -flags:v +global_header+cgop -movflags +faststart -mpegts_service_id 0x2fb8 -mpegts_pmt_start_pid 0x3ee -g 125 -f tee "[select=\'a:0,v:0,a:1,v:1,a:2,v:2,a:3,v:3\':f=hls:hls_list_size=10:hls_segment_filename=/opt/streams/cache/hls/20/playlist_%v_%d.ts:hls_flags=delete_segments:master_pl_name=20.m3u8:var_stream_map=\'v:0,a:0 v:1,a:1 v:2,a:2 v:3,a:3\']/opt/streams/cache/hls/20/playlist_%v.m3u8" I tired with -rtbufsize, -re, -deint 2 (it was before, i read that it can be problem so i changed to 1 and it not helps).

11 Dec '20

Trying to transcode a file and perform a pixel conversion from 8 to 10 bit.

Ffmpeg list camera capabilities
by Alan White 10 Dec '20

10 Dec '20

Hi folks, Can anyone help me understand how to trigger ffmpeg to list the resolutions and frame rates supported by attached video cameras on Linux please? With dshow on windows the options can be listed, with avfoundation on macOS you can pass a bogus frame rate and it lists the valid ones however on Linux all I can find is the list of supported resolutions for supported encoding formats, no frame rates. I know I could use v4l2-ctl if it was installed, but I’m hoping to be able to avoid obliging users to install that. Ultimately I’d like to be able to use the apis from libav* to get this info, but initially looking to scrape the answers from ffmpeg output. Thanks Alan Alan White alan(a)whitemail.net
