Anamorphic 16:9 SD-DV(D) widescreen to AV1.webm
by Terje J. Hanssen 16 Jan '24

16 Jan '24

I wanted to test AV1.webm rendering from anamorphic 16:9 SD-DV(D) widescreen sources, which have different SAR 64:45 than 1080i HDV SAR 4:3 It would be fine to get this SAR value verified and clarified vs Wikipedia's table which specifies different for PAL (16:9) 720x576 : SAR 5:4, PAR 64:45 https://en.wikipedia.org/wiki/Pixel_aspect_ratio#Pixel_aspect_ratios_of_com… This legacy 16:9 SD format was created and can be obtained among the following methods:: 1. DV camcorders with Widescreen feature, the right/true way and wrong/fake way https://www.videouniversity.com/articles/dv-formats-everything-you-need-to-… 2. DV wide record or downconvert playback using a HD(V) camcorder with this feature 3. DVD video disc enhanced for 16:9 or a BD video disc with 16:9 SD content 4. Render/transcode i.e a HD(V) video file using a) Cin-GG b) FFmpeg I have used the two latter methods as follows: 4 a) Cin-GG Loaded a PAL 1080i/50 HDV clip Set Format Preset: PAL 576i (16:9) - DV(D) File Render File Format: FFmepg - avi (NB! because plain Raw DV still causes DAR 4:3) Audio: Preset: avi_pcm_s16.avi Video: Compression: dv_pal.avi ffprobe -hide_banner dv07_05_wide_cingg.avi Input #0, avi, from 'dv07_05_wide_cingg.avi': Metadata: software : Lavf60.16.100 Duration: 00:06:58.04, start: 0.000000, bitrate: 30342 kb/s Stream #0:0: Video: dvvideo (dvsd / 0x64737664), yuv420p, 720x576 [SAR 64:45 DAR 16:9], 28802 kb/s, 25 fps, 25 tbr, 25 tbn, 25 tbc Stream #0:1: Audio: pcm_s16le ([1][0][0][0] / 0x0001), 48000 Hz, 2 channels, s16, 1536 kb/s mediainfo dv07_05_wide_cingg.avi General Complete name : dv07_05_wide_cingg.avi Format : AVI Format/Info : Audio Video Interleave Commercial name : DV Format profile : OpenDML Format settings : BitmapInfoHeader / PcmWaveformat File size : 1.48 GiB Duration : 6 min 58 s Overall bit rate mode : Constant Overall bit rate : 30.3 Mb/s Frame rate : 25.000 FPS Writing application : Lavf60.16.100 Video ID : 0 Format : DV Codec ID : dvsd Codec ID/Hint : Sony Duration : 6 min 58 s Bit rate mode : Constant Bit rate : 24.4 Mb/s Width : 720 pixels Height : 576 pixels Display aspect ratio : 16:9 Frame rate mode : Constant Frame rate : 25.000 FPS Standard : PAL Color space : YUV Chroma subsampling : 4:2:0 Bit depth : 8 bits Scan type : Interlaced Scan order : Bottom Field First Compression mode : Lossy Bits/(Pixel*Frame) : 2.357 Stream size : 1.40 GiB (95%) Audio ID : 1 Format : PCM Format settings : Little / Signed Codec ID : 1 Duration : 6 min 58 s Bit rate mode : Constant Bit rate : 1 536 kb/s Channel(s) : 2 channels Sampling rate : 48.0 kHz Bit depth : 16 bits Stream size : 76.6 MiB (5%) Alignment : Aligned on interleaves Interleave, duration : 208 ms (5.21 video frames) 4 b) FFmpeg transcode HDV to DV-wide ffmpeg -hide_banner -i hdv07_05.m2t -vf scale=720:576,setsar=64/45,setdar=16/9 -c:v dvvideo -c:a pcm_s16le dv07_05_wide.dv Stream mapping: Stream #0:0 -> #0:0 (mpeg2video (native) -> dvvideo (native)) Stream #0:1 -> #0:1 (mp2 (native) -> pcm_s16le (native)) Stream #0:0: Video: dvvideo, yuv420p(tv, bt709, top coded first (swapped)), 720x576 [SAR 64:45 DAR 16:9], q=2-31, 200 kb/s, 25 fps, 25 tbn Stream #0:1: Audio: pcm_s16le, 48000 Hz, stereo, s16, 1536 kb/s frame=10457 fps=356 q=-0.0 Lsize= 1440422kB time=00:06:58.28 bitrate=28210.6kbits/s dup=217 drop=0 speed=14.3x ffprobe -hide_banner dv07_05_wide.dv [dv @ 0x56036476e580] Estimating duration from bitrate, this may be inaccurate Input #0, dv, from 'dv07_05_wide.dv': Metadata: timecode : 00:00:00:00 Duration: 00:06:49.72, start: 0.000000, bitrate: 28800 kb/s Stream #0:0: Video: dvvideo, yuv420p, 720x576 [SAR 64:45 DAR 16:9], 25000 kb/s, 25 fps, 25 tbr, 25 tbn, 25 tbc Stream #0:1: Audio: pcm_s16le, 48000 Hz, stereo, s16, 1536 kb/s mediainfo dv07_05_wide.dv General Complete name : dv07_05_wide.dv Format : DV Commercial name : DVCAM File size : 1.37 GiB Duration : 6 min 49 s Overall bit rate mode : Constant Overall bit rate : 28.8 Mb/s Frame rate : 25.000 FPS Recorded date : 1970-01-01 00:00:00.000 Video Format : DV Commercial name : DVCAM Duration : 6 min 49 s Bit rate mode : Constant Bit rate : 24.4 Mb/s Width : 720 pixels Height : 576 pixels Display aspect ratio : 16:9 Frame rate mode : Constant Frame rate : 25.000 FPS Standard : PAL Color space : YUV Chroma subsampling : 4:2:0 Bit depth : 8 bits Scan type : Interlaced Scan order : Top Field First Compression mode : Lossy Bits/(Pixel*Frame) : 2.357 Time code of first frame : 00:00:00:00 Time code source : Subcode time code Stream size : 1.17 GiB (85%) Audio ID : 0 Format : PCM Format settings : Big / Signed Duration : 6 min 49 s Bit rate mode : Constant Bit rate : 1 536 kb/s Channel(s) : 2 channels Sampling rate : 48.0 kHz Bit depth : 16 bits Stream size : 75.0 MiB (5%) --------------------------------- The HDV source has Scan order : Top Field First What would be right, Top or Bottom Field First for the output file (they differ)?

I tried again with commit 677df71d1663090d5a9ee3b1e48c3c17cb5cc8a2 from https://github.com/heroineworshiper/hvirtual it seems to link and work if I add two patches on top of it, attached (one git and one just plain diff) There was also problem libraw-1.2.0 - i just run libtoolize/autoreconf -f commands in this thirdparty directory

current set of my patches
by Andrew Randrianasulu 15 Jan '24

15 Jan '24

So, I tried to clarify a bit that we have display aspect ratio selectable, updated cingg team copyright year, added even more finegrained sar/dar reporting (guessed, container detected, codec detected). I tried to use libavutil function for reporting SAR in setformat.C but it need some dynamic gui subwindow/object, not static BCTitle... so just prototype that does not update as you update window, only calculated on window objects create time, so each time you reopen set format window. 3 new git diff patches hopefully for application 0003 should be applied on top of 0001-Add-guessed-detected-SAR-DAR-values-to-ffmpeg-asset-.patch from another thread one plain diff patch just for showing where SAR info might surface if I ever learn now to create dynamic text subwindows :)

Set stream sample aspect ratio in ffmpeg.C
by Andrew Randrianasulu 15 Jan '24

15 Jan '24

Now it seems to display correct (16/9) DAR for sample encoded directly from hdv. (but for speed I tested vp8/webm, not av1/webm)

When input format and output rendering formats are identical, it seems that nothing needs to be set/edited manually in Set Format. Then the unavoidable request/suggestion: Could correspondingly different I/O format via selected Presets also bake in Autoscale as default (beside color space mentioned before) ? (refer to the: -vf scale=720:576,setsar=64/45,setdar=16/9 in the ffmpeg line below) >> According to my understanding this should down-convert the full source image to DVD 16:9 anamorphic format, which at playback should display upscaled 16:9 screen. >> That is, just as in my first post >> 4 b) FFmpeg transcode HDV to DV-wide >> ffmpeg -hide_banner -i hdv07_05.m2t -vf scale=720:576,setsar=64/45,setdar=16/9 -c:v dvvideo -c:a pcm_s16le dv07_05_wide.dv >> >> Gnome File properties and VLC Tools Codec info just say1440x1080 resolution for the HDV source and 720x576 for the CinGG rendered avi and dv output. >> I don't know if it possible to find out exactly, but >> >> Visually I espect and will estimate that the "middle part" 720x576 px symmetrical around the center of the source image is kept.

Video Formats and the latest players AV1, WebM, HEIF

AV1 and WebM: Play it with your browser and smart-phone! I've just tested PAL HDV 16:9 and SD-DV 4:3 video clips rendered with Cin-GG to AV1 video and Opus audio muxed in a WebM container. They playback fine in VLC mediaplayer and not at least in Firefox and Google-Chrome browsers on Linux. Transferred these WebM clips using Gnome File manager on Linux to my smart-phone Google Pixel 7 Pro via USB connection. Tested these AV1 WebM clips playback worked fine on Pixel 7 with Android 14, possibly using its Tensor hw decoder.

vorbis encoding param fix ?

was about to suggest to try plain audio encoding via our own vorbis encoder but recognized settings were not working. Hopefully attached patch fixes audio-only ogg native encoding param dialog. Can you try it out?

in ffmpeg asset detailed info for files like HDV info is guessed, for files like mov / mp4 you sometimes can get detection working. code lifted from dump.c and ffprobe.c
