from Imagemagick sources.. https://github.com/ImageMagick/dcraw/commit/00d7d612efb84e27e465a7fbeca355e… but you can try latest (dcraw 9.28) commit from this repo.. in theory it might make cingg's raw decoding a bit faster on opencl-capable gpu... only performace claim I found was "With an OpenCL version of dcraw.c converting an 6034x4012 NEF file to JPEG takes 4.7 seconds instead of 13.8 seconds on my machine. 1:05 AM · 25 мая 2016 г.·" - https://mobile.twitter.com/MagickNET/status/735230384615661568

Playing catchup with randrik12 patches
by Phyllis Smith 17 Oct '21

17 Oct '21

Andrew, when I add the following line to ...thirdparty/Makefile, it errors out pretty much right away: opus.cfg_vars?= --disable-extra-programs This is in randrik12/0052-fix-opus-configure.patch and it would be nice to have this to save a little time.

offtopic: Digitize and record Video with A/D USB adapters
by Terje J. Hanssen 14 Oct '21

14 Oct '21

Although I have and have used some Black Magic external tools for this, I'm also interested in simple and low cost options for Linux workstations. In a recent article the Augustin VGB100 usb2.0 video adaper and VLC was used to record video https://www.arsouyes.org/en/blog/2021/2021-05-17_Numerisation_VHS Any experience here with similar A/D video adapters, quality and applications for recording on Linux?. Second I wonder if some lossless, compressed master video format is available for better quality before final converting with typical ffmeg? And third, maybe a stupid question: Is it possible to record just Audio with an A/D Video adapter, which audio record format and what quality, compared with a pure Audio adapter? And if so, can audio record applications like Audiacity be used? Terje

Debian 32-bit on Qemu
by Andrea paz 12 Oct '21

12 Oct '21

I have installed a Debian 11.1 32-bit on qemu. What packages do I need in order to compile CinGG from git? I remember there used to be a dependency checking script, but I, with Arch, have never used it. Or is it better to use some other installation method?

[WIP] connecting pluginprefs.C back to codebase
by Andrew Randrianasulu 11 Oct '21

11 Oct '21

Basically just monkeying around (it does not do anything with local plugin set) but I can try and push this a bit more so it will actually search plugins in second location I think main idea was to alliw 'favorities' set of plugins somewhere in user dir, if user can't change stuff in /usr. Today Cingg can look in dufferent places for plugins depending on env. variables, still gui might be handy for some users. Also, it show how to add new category in oreferences, so we can offload few things into new tab in the future (or just add them there)

libaom 3.1.1 patch for Ubuntu 16.04.7
by Andrew Randrianasulu 10 Oct '21

10 Oct '21

It seems Cmake version bump in libaom 3.1.x was mostly cosmetic - it builds with attached patch (put in thirdparty/src) right now this new (CinelerraGG/ffmpeg-4.4/libaom-3.1.1) build completes - so not tested yet.

DPX sequence in CinGG
by Andrea paz 09 Oct '21

09 Oct '21

I tried to make an ffmpeg profile of the DPX standard movie format. So now CinGG has DPX support inside ffmpeg and OpenEXR outside of ffmpeg. Remember that these two formats produce a sequence of still images and their relative TOC (it is only the TOC that needs to be imported into CinGG when we want to load this format). So it's good to create a folder where to put all the images and the TOC produced, which are hundreds and even thousands. Big space occupation but super efficient in timeline and great quality. I attach the profile if you want to test it.

offtopic: Digitize and record Audio via Line-In Jack or via USB adapter?
by mat 06 Oct '21

=== Terje:===== 1) My Behringer UFO202 USB Audio interface has arrived. As a first and easy test I have connected it to a PC USB port, the RCA IN L+R to RCA OUT on a Toshiba videoplayer playing an Audio music CD, and third connected earphones to UFO202. 2) Yes, I hear the playback sound in the earphones, however no sound if I plugin the earphones to the normal rear PC backplane's Jack, and no sound in the corresponding speakers. Correct so far? =========== That is normal. By default, incoming (line) signals are not rerouted to outputs, some software must do that. === Terje:===== 3) pavucontrol Configuration | *PCM2902 Audio Codec* Profile: Analog Stereo Duplex * Input Devices | Hardware devices | Hardware Input Devices: PCM2902 Audio Codec Analog Stereo, Port: Analog Input response Built-in Audio Analog stereo, Port: Rear Microphone (plugged in) Respons!? ================ Looks good. Here I have for the non-PCM2902 device (HD audio controller analog stereo) port Line 1, and plugged in. === Terje:===== 4) UFO202 is discovered on my Leap 15.3 as *Device 4 **Texas Instruments PCM2902 Audio Codec* as follows: ... ================ Looks good, same here, except here the video HDMI is the first device and the motherboard HD audio the second. PCM2902 is third also. === Terje:===== pacmd list-sources | egrep '^\s+name: .*alsa_input' ================ Output looks fine. === Terje:===== 5) I am unsure how to practically go from here to record the Audio music files. ================ 8) Which tab/buttons for input in Audiacity (possibly tape/noise filters) - I could not find the PCM2902 input or see any sound response here I suggest to try Audacity first. In Edit->Preferences->Devices, Host Alsa, playback device pulse, recording default (or pulse), 1 or 2 channels as desired. Edit->Preferences->Recording, record on new track (each time you start a recoding you get a new audio track). Then, on the main menu, click on the filed that says "click to start monitoring", this will send input to output, so if your output device is line out it will come out there. For recording, the red button starts recording, the black square button stops. The advantage of using Pulse is that pavucontrol will show recoding applications, you should also see the signal coming in when an application is recording (has opened the input channel). This can be seen on the Input Devices tab. You don't see the device as such, it is "abstracted" by both Also and then PulseAudio. === Terje:===== 9) Would it be reasonable to record and archive in lossless FLAC format and afterwards convert with ffmpeg? to smaller files format of good quality, typical MP3 at 320 kbps (for car usb player) and MP4A for home HiFi? ================ FLAC is very good, it itself is lossless. Audacity can export to a variety of formats (File->Export), I usually use mp3 or wav. Note that if you do a lot of editing on a recording is it better to save the project, that avoid converting back-and-forth between flac and the interanl Audacity 32 bit floats. Audicity is a good editor, you record first, save the original recoding, then apply filters/effects/cuts etc . Like CinGG, keep the original intact. Offhand, I'd say you must have extremely good hearing to hear differences between MP3 320kbps and the original. For cars, I myself would not go above 128 kbps. MP3 at 320 kbps is much better than most home HiFi. And if the source is not digital, (but tape or cassette), 128 kpbs MP3 is already much better than the source material. ========= In CinGG, you could try Alsa, CinGG shows the device directly. Preferences->recording tab. Record driver Also, then you get in the Devoce dropdown box multiple devices, look for something like USB Audio. If you have webcam also connected, you are likely to see two of them. I did have some problems there, my settings are Record driver "Pulse Audio" , leave the device at default. Then pavucontrol determines which devices. I am not sure if the sample rate is set corretly for the device by CinGG, if it does not work or you get lots of errors, try 44100 instead of 4800, the UFO202 supports both. Good luck, Mat

Your MSI Z170-A PRO motherboard has according to specs a Realtec AL892 audio chip. The input converters should have 90 dB S/N (signal-to- noise) ratio (A-weighted), but of course the motherboard might make it a little worse. However, from you record player of tape you will be very lucky to get better than 65 dB S/N. So if an A-D converter has a S/N of 70 dB or better, it is more than good enough for this. Regarding your PC input channels, on current desktop motherboards I usually see three 3.5 mm mini-jacks. Their recording quality for line- in is close to 90 dB S/N or even above 100 on the better ones. In pavucontrol (audio mixer), first check the configuration tab, to see if the Built-in Audio is set up correctly. "Analog stereo duplex" is probably right. Then, on the "Input devices" tab, at the bottom set it to show "Hardware Input Devices", then check that the Port is set to the correct port. For me, "Line In" shows correctly if something is plugged in or not. Make also sure the gain is set to 100%. That said, I sometimes have problems recording LineIn with Audacity, even though all seems OK. have not yet determined what the cause is. External USB sound cards can be quite good, if you stay away from the very cheap ones that are mic/phone only. I have a Behringer UCA-202 which is good enough for this, but there are much better ones (at a price), look at music-oriented webshops. I presume to have an RIAA pre- amp for you record player, these are usually set up for less output that typical PC or usb-audio input, which expect 1 Volt. Drivers are not needed, and disregard any reviews that don't show measurements. MatN
