Trouble transcoding with cuda
by Ray Randomnic 06 Sep '19

Hey folks, I'm trying to transcode an HEVC (yuv420p10le) encoded file to H264 using a GTX 1650 nvenc and having issues with what I assume are the pixel formats conversions on hardware. My encode speed (in fps) is pretty low (see below), far lower than I get when transcoding HEVC -> HEVC. ffmpeg version is N-94578-gd6bd902599-gcff309097a+3 (on a Windows 10 OS, though I don't think this is relevant). For the purposes of this experiment, let's say I'm not concerned with lossiness with format conversions. I'd like to know what I'm doing wrong and what commands I can issue for the following: decode on GPU -> format conversion (if necessary) on GPU -> encode on GPU. I might not be understanding a few concepts. The combination of options that I thought were available and I tried out are: - decoder (I mostly left this blank for auto) and encoder (always h264_nvenc) - hwaccel - hwaccel_output_format - filters (vf): - format - scale_npp (for format conversion on gpu) I have no idea what the options pix_fmt or other filters like colorspace do for hardware (how is pix_fmt different from hwaccel_output_format?). At this point I'm kind of stuck. Don't know how to convert formats on the GPU (I assume the format conversion is happening on the CPU). Input details: ffprobe input.mp4 Stream #0:0(eng): Video: hevc (Main 10) (hvc1 / 0x31637668), yuv420p10le(tv, bt2020nc/bt2020/smpte2084), 1920x1080, 24886 kb/s, SAR 1:1 DAR 16:9, 29.99 fps, ... Summary of various combinations (- indicates left blank): test | hwaccel | hwaccel_output_format | filter (vf) | encodefps | note 1 | cuda | - | - | X | Failed 2 | cuda | cuda | - | X | Failed 3 | cuda | yuv420p | - | 361 | Video messed up 4 | cuda | cuda | format=yuv420p | X | Failed 5 | cuvid | cuda | format=yuv420p | 91 | Not using GPU decode 6 | cuda | - | format=yuv420p | 161 | Not using GPU format conversion 7 | cuvid | - | format=yuv420p | 91 | Not using GPU decode 8 | cuda | - | scale_npp=format=yuv420p | X | Failed 9 | cuda | cuda | scale_npp=format=yuv420p | X | Failed I would expect a speed of around test 3 (without the screwed up video). Is there any way to convert the pixel formats on the hardware without screwing up the video? On a similar note, I'd love for someone to explain the failing encodes. Here are the details for corresponding encodes: 1. ffmpeg -loglevel verbose -hwaccel cuda -i input.mp4 -c:v h264_nvenc output.mp4 Fails with the following: [graph_1_in_0_1 @ 000001cc9670e4c0] tb:1/48000 samplefmt:fltp samplerate:48000 chlayout:0x3 [hevc @ 000001cc8740fc00] NVDEC capabilities: [hevc @ 000001cc8740fc00] format supported: yes, max_mb_count: 262144 [hevc @ 000001cc8740fc00] min_width: 144, max_width: 8192 [hevc @ 000001cc8740fc00] min_height: 144, max_height: 8192 [graph 0 input from stream 0:0 @ 000001cc87420840] w:1920 h:1080 pixfmt:p010le tb:1/90000 fr:30/1 sar:1/1 sws_param:flags=2 [h264_nvenc @ 000001cc8747fbc0] Loaded Nvenc version 9.0 [h264_nvenc @ 000001cc8747fbc0] Nvenc initialized successfully [h264_nvenc @ 000001cc8747fbc0] 1 CUDA capable devices found [h264_nvenc @ 000001cc8747fbc0] [ GPU #0 - < GeForce GTX 1650 > has Compute SM 7.5 ] [h264_nvenc @ 000001cc8747fbc0] 10 bit encode not supported [h264_nvenc @ 000001cc8747fbc0] No NVENC capable devices found [h264_nvenc @ 000001cc8747fbc0] Nvenc unloaded Error initializing output stream 0:0 -- Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height 2. ffmpeg -loglevel verbose -hwaccel cuda -hwaccel_output_format cuda -i input.mp4 -c:v h264_nvenc output.mp4 Fails with the following: [graph_1_in_0_1 @ 00000240b7932340] tb:1/48000 samplefmt:fltp samplerate:48000 chlayout:0x3 [hevc @ 00000240b79e37c0] NVDEC capabilities: [hevc @ 00000240b79e37c0] format supported: yes, max_mb_count: 262144 [hevc @ 00000240b79e37c0] min_width: 144, max_width: 8192 [hevc @ 00000240b79e37c0] min_height: 144, max_height: 8192 [graph 0 input from stream 0:0 @ 00000240b7937e00] w:1920 h:1080 pixfmt:cuda tb:1/90000 fr:30/1 sar:1/1 sws_param:flags=2 [h264_nvenc @ 00000240b7483700] Loaded Nvenc version 9.0 [h264_nvenc @ 00000240b7483700] Nvenc initialized successfully [h264_nvenc @ 00000240b7483700] 10 bit encode not supported [h264_nvenc @ 00000240b7483700] Provided device doesn't support required NVENC features [h264_nvenc @ 00000240b7483700] Nvenc unloaded Error initializing output stream 0:0 -- Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height Alright, so it seems that the hardware h264 encoder doesn't support 10 bit encodes (that's coming from the decoder).

coding video for some old Sony
by Erik Dobák 06 Sep '19

06 Sep '19

Hi, i have an old Sony Bravia which accepts only MPEG4 as video and MP3 as audio. If i want to watch videos i do it with this command: ffmpeg -i the_kingdom_of_dreams_and_madness.mp4 -b:v 1M -vcodec mpeg4 -vtag xvid -acodec libmp3lame -q:a 2 the_kingdom_of_dreams_and_madness.avi but for some reason some video do not play at all. some do. is there a way that the input video could influence the output? I thought that when i resample with ffmpeg to these basic codecs all will work... Any hints? E

ffmpeg : Record and preview at the same time

Hello I'm on a project around a Rpi and a webcam with micro USB under rasbian. I correctly save the video and sound in a file: ffmpeg -y -f alsa -i hw: 1 -itsoffset 0.5 -i / dev / video0 -vcodec h264_omx -b: v 2M output-dev-video2-omx.mkv I visualize correctly in real time what points the webcam (I do not need the audio) on this preview: ffmpeg -i / dev / video0 -f avi -codec copy pipe: 1 | ffplay -i blowjob: 0 -> by cons I can not conceive a line: recording in a file, with sound, and at the same time see on my screen what my webcam is filming, a preview in a way. thank you, cDL --- L'absence de virus dans ce courrier électronique a été vérifiée par le logiciel antivirus Avast. https://www.avast.com/antivirus

how to keep decoded frame of h264_cuvid in cuda memory.
by heyufei2008＠outlook.com 05 Sep '19

05 Sep '19

Hi I use h264_cuvid to decode h.264 files. Format of the decoded frames is AV_PIX_FMT_NV12, and it's in host. How to keep the decoded fames stay in cuda memory? I need the frames for 3D rendering. Thanks. John

Audible aax files and concat demuxer
by Hans Carlson 04 Sep '19

04 Sep '19

If I decode an audible aax file using the -activation_bytes option it works fine for a single file, eg: $ ffmpeg -activation_bytes XXXXXXXX -i part-1.aax -codec copy part-1.mp4 BUT if I try to concat multiple files using the concat demuxer it acts like the -activation_bytes option isn't supplied. This feels like a bug? $ cat parts.txt file part-1.aax file part-2.aax $ ffmpeg -activation_bytes XXXXXXXX -f concat -i parts.txt -codec copy parts.mp4 ffmpeg version N-94778-g787c56b9e9 Copyright (c) 2000-2019 the FFmpeg developers built with gcc 7 (GCC) configuration: --enable-libfdk-aac libavutil 56. 34.100 / 56. 34.100 libavcodec 58. 56.101 / 58. 56.101 libavformat 58. 32.104 / 58. 32.104 libavdevice 58. 9.100 / 58. 9.100 libavfilter 7. 58.102 / 7. 58.102 libswscale 5. 6.100 / 5. 6.100 libswresample 3. 6.100 / 3. 6.100 [mov,mp4,m4a,3gp,3g2,mj2 @ 0x2c40580] [aax] file checksum == 21cd2a0732a1b2972e61a4e284da6720b2baba9f [mov,mp4,m4a,3gp,3g2,mj2 @ 0x2c40580] [aax] activation_bytes option is missing!

I can get around this by decoding each part individually and then using the concat demuxer on the decoded parts, but the above still seems like a bug to me.

Best way to get a average bit rate per stream?
by August Johansson 03 Sep '19

03 Sep '19

Hi, I would like to store the average bit rate of every stream in my database. I tested using ffprobe -print_format json -show_streams but this information does not seem to be there. What would be the best way to return this information? Thanks
