ms2130 HDMI-USB3 UHD capture card - not quite as expected?
by Terje J. Hanssen 09 Mar '23

09 Mar '23

So I have received the ms2130 HDMI-USB3 capture card. The A/D AV converter & SV-HDMI/adapter is not received so far, and I have not avialable my HDV camcorder (on service) to output HDMI video stream with. Yet, I have initially run some verification tests on the ms2130 HDMI-USB3 UHD capture card alone, for what they are worth. As "UHD" (and/or USB3) is mostly generic used to identify this card (while ms2130 almost not), the some output is piped and stripped with grep "UHD". ---------------- dmesg | grep UHD [ 2.798210] usb 2-5: Product: USB3.0 UHD [ 2.827772] hid-generic 0003:345F:2130.0005: hiddev97,hidraw4: USB HID v1.10 Device [MACROSILICON USB3.0 UHD] on usb-0000:00:14.0-5/input4 [ 4.805554] usb 2-5: Found UVC 1.00 device USB3.0 UHD (345f:2130) udevadm info /dev/video* | egrep 'DEVNAME|ID_V4L_PRODUCT' E: DEVNAME=/dev/video0 E: ID_V4L_PRODUCT=USB 2.0 Camera: HD 720P Webcam E: DEVNAME=/dev/video1 E: ID_V4L_PRODUCT=USB 2.0 Camera: HD 720P Webcam E: DEVNAME=/dev/video2 E: ID_V4L_PRODUCT=USB3.0 UHD: USB3.0 UHD E: DEVNAME=/dev/video3 E: ID_V4L_PRODUCT=USB3.0 UHD: USB3.0 UHD udevadm info /dev/video* | egrep UHD S: v4l/by-id/usb-MACROSILICON_USB3.0_UHD_20210623-video-index0 E: ID_V4L_PRODUCT=USB3.0 UHD: USB3.0 UHD E: ID_MODEL=USB3.0_UHD E: ID_MODEL_ENC=USB3.0\x20UHD E: ID_SERIAL=MACROSILICON_USB3.0_UHD_20210623 E: DEVLINKS=/dev/v4l/by-id/usb-MACROSILICON_USB3.0_UHD_20210623-video-index0 /dev/v4l/by-path/pci-0000:00:14.0-usb-0:5:1.0-video-index0 S: v4l/by-id/usb-MACROSILICON_USB3.0_UHD_20210623-video-index1 E: ID_V4L_PRODUCT=USB3.0 UHD: USB3.0 UHD E: ID_MODEL=USB3.0_UHD E: ID_MODEL_ENC=USB3.0\x20UHD E: ID_SERIAL=MACROSILICON_USB3.0_UHD_20210623 E: DEVLINKS=/dev/v4l/by-path/pci-0000:00:14.0-usb-0:5:1.0-video-index1 /dev/v4l/by-id/usb-MACROSILICON_USB3.0_UHD_20210623-video-index1 lsusb | grep UHD Bus 002 Device 004: ID 345f:2130 MACROSILICON USB3.0 UHD cat /proc/asound/cards | grep UHD 2 [UHD ]: USB-Audio - USB3.0 UHD MACROSILICON USB3.0 UHD at usb-0000:00:14.0-5, super speed ll /dev/video* crw-rw----+ 1 root video 81, 0 feb. 25 14:15 /dev/video0 crw-rw----+ 1 root video 81, 1 feb. 25 14:15 /dev/video1 crw-rw----+ 1 root video 81, 2 feb. 25 14:15 /dev/video2 crw-rw----+ 1 root video 81, 3 feb. 25 14:15 /dev/video3 --------------------- v4l2-ctl --list-devices USB 2.0 Camera: HD 720P Webcam (usb-0000:00:14.0-11): /dev/video0 /dev/video1 USB3.0 UHD: USB3.0 UHD (usb-0000:00:14.0-5): /dev/video2 /dev/video3 ----------- v4l2-ctl --list-formats-ext ioctl: VIDIOC_ENUM_FMT Index : 0 Type : Video Capture Pixel Format: 'YUYV' Name : YUYV 4:2:2 Size: Discrete 640x480 Interval: Discrete 0.030s (33.000 fps) Interval: Discrete 0.067s (15.000 fps) Size: Discrete 1280x720 Interval: Discrete 0.100s (10.000 fps) Size: Discrete 640x360 Interval: Discrete 0.030s (33.000 fps) Interval: Discrete 0.067s (15.000 fps) ................

07 Mar '23

I opened a thread in the forum but I also post here to let people know about 2 interesting programs: 1- An interesting program for reviewing videos, VFX and animations: https://darbyjohnston.github.io/DJV/index.html Useful especially in the Pro environment. It has a license similar to Open Source but is not fully open. 2- Simpler but Open Source licensed: https://www.dneg.com/xstudio/

Ffmpeg 6 has come out. In a couple of months 6.1 will come out. Few additional filters but, they say, a lot of work under the hood. https://ffmpeg.org/

DVD compliant MPEG-2 Video and PCM Audio
by Terje J. Hanssen 06 Mar '23

06 Mar '23

I thought to create a DVD compliant MPEG2 Video and PCM Audio using the same principles as earlier for BD video. The sample source input is a raw DV25 PAL file which includes PCM audio: ffprobe -hide_banner dv28.dv [dv @ 0x55dc6248cf00] Estimating duration from bitrate, this may be inaccurate [dv @ 0x55dc6248cf00] Could not find codec parameters for stream 0 (Video: dvvideo, none, 25000 kb/s): unspecified size Consider increasing the value for the 'analyzeduration' (0) and 'probesize' (5000000) options Input #0, dv, from 'dv28.dv': Metadata: timecode : 00:00:00:00 Duration: 00:02:16.64, start: 0.000000, bitrate: 28800 kb/s Stream #0:0: Video: dvvideo, none, 25000 kb/s, SAR 16:15 DAR 0:0, 25 fps, 25 tbr, 25 tbn Stream #0:1: Audio: pcm_s16le, 48000 Hz, stereo, s16, 1536 kb/s Unsupported codec with id 24 for input stream 0 1) ffmpeg encoding DV to MPEG-2 video and copy PCM audio as is to a VOB/MPG format: ffmpeg -i dv28.dv -c:v mpeg2video -refs 1 -bf 2 -b:v 8M -maxrate 8M -minrate 8M -bufsize 20M -muxrate 11M -dc 10 -c:a pcm_s16be -f vob -flags +ilme+ildct dv28.mpg ............. a lot of warning messages [vob @ 0x55b227ae4240] packet too large, ignoring buffer limits to mux it [vob @ 0x55b227ae4240] buffer underflow st=1 bufi=6744 size=7680 .................. frame= 3416 fps=400 q=3.6 Lsize= 161296kB time=00:02:16.64 bitrate=9670.2kbits/s speed= 16x video:133611kB audio:25620kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: 1.296714% I've tried various bufsizes and muxrate sizes, but still the warning messages arise. Suggestions? ffprobe -hide_banner dv28.mpg Input #0, mpeg, from 'dv28.mpg': Duration: 00:02:16.64, start: 0.540000, bitrate: 9670 kb/s Stream #0:0[0x1e0]: Video: mpeg2video (Main), yuv420p(tv, bottom first), 720x576 [SAR 16:15 DAR 4:3], 25 fps, 25 tbr, 90k tbn Side data: cpb: bitrate max/min/avg: 8000000/0/0 buffer size: 20004864 vbv_delay: N/A Stream #0:1[0xa0]: Audio: pcm_dvd, 48000 Hz, stereo, s16, 1536 kb/s The resulting dv28.mpg file seems to playback fine with video and audio in ffplay and VLC Afterwards I loaded it as input to tsMuxer, and muxed it to dv28.ts, in lack of a button to create an DVD ISO similar like simple Blu-ray ISO du -sh dv28.* 470M dv28.dv 158M dv28.mpg 164M dv28.ts Any idea how to create a simple DVD iso with tsMuxer command line if possible, or with other tools?

FYI: for some reason the CinGG mailing list is not getting to me
by Phyllis Smith 04 Mar '23

04 Mar '23

Just an FYI. I have not received mail when addressed to the CinGG mailing list since Feb. 27. Do not know why and my secondary address is not either. Must be something wrong with the router here. Will look at the Mailing List Archives to see what I am missing. (Sarcasm - it shouldn't take me more than 6 months to fix it as there is always something broken here, especially light bulbs).

a bit ot: performance vs clean programming (yt, 22 min)
by Andrew Randrianasulu 03 Mar '23

03 Mar '23

https://m.youtube.com/watch?v=tD5NrevFtbU well, I guess in cinelerra case even just time to initially type in all that code was relevant :) but I found it quite heartwarming how someone finally noticed how nicely-looking code may perform ....suboptimally. So, I wish all programmers to find right balance between nice features and nice performance :)

Capturing DV/HDV via Firewire
by Terje J. Hanssen 01 Mar '23

01 Mar '23

IEE 1394 / FireWire (Apple) / i.LINK (Sony) has been a standard connection to transfer native DV and HDV video files to Lin/Win/Apple computers. * FireWire DV/HDV recording should still work via dvgrab, vlc, guvcview, OBS and ffmpeg etc., or directly via some NLE systems. * The basic dvgrab tool is still valid on Linux and was mentioned in the Cin-CV wiki sect. 19.2 * http://cinelerra-cv.wikidot.com/cincv-manual-en:capturing-media#5 * ffmpeg enabled FireWire DV/HDV input device using libiec61883 (Streamcopy) seems also interesting. On my Leap 15.4 or Tumbleweed, ffmpeg-5 is seemingly not compiled with --enable-libiec61883. Is possibly ffmpeg available with enabled libiec61883 via Cin-GG? http://www.ffmpeg.org/ffmpeg-devices.html#iec61883 http://underpop.online.fr/f/ffmpeg/help/iec61883.htm.gz I had a look into the Cin-GG manual chpt 13 "Capturing and Recording Media", but could not see Firewire media transfer was mentioned. However, in the Appendice section B.2 Configuration Features, Optional Packages is found: --with-firewire use firewire (auto) --with-dv use dv (auto) Does this mean that Firewire/dv capture already is supported or optional can be configured?

Virtualized Fedora armhf
by Andrew Randrianasulu 27 Feb '23

27 Feb '23

So I was looking at easy way to get fedora-arm/aarch64 (because install is so slow ....) May be this guide can help (assumes Fedora as base os): https://michel-slm.name/posts/2020-08-20-fedora-armhfp-vm/ while I looked at slightly different image location, for newer os image (2.8 gb for xfce4 image!) https://dl.fedoraproject.org/pub/fedora/linux/releases/36/Spins/armhfp/imag… namely https://dl.fedoraproject.org/pub/fedora/linux/releases/36/Spins/armhfp/imag… for Fedora 37 I only found aarch64 image (small one, so you need to install a lot!).. https://dl.fedoraproject.org/pub/fedora/linux/releases/37/Cloud/aarch64/ima…

OpenCL again
by Andrew Randrianasulu 27 Feb '23

27 Feb '23

So, I run veeery experimental clvk (OpenCL via Vulkan) on my termux, ffmpeg tried to init filter but died. I guess my day is not today ... Anyway, my test line was: ffmpeg -init_hw_device opencl=gpu -filter_hw_device gpu -i ~/20210419_055507A.mp4 -vf "hwupload, boxblur_opencl, hwdownload,format=yuv420p" -f null /dev/null for different filters format might be yuv420p or nv12 ... I wonder if anyone here have working OpenCL ffmpeg setup ? I'll try with llvmpipe/rusticl on desktop .... but it guaranteed to be slow.
