Manual Appendix: Keyframes and Plugins
by Andrea paz 01 Jan '23

01 Jan '23

I have added a new section to the "Real-World" appendix. It is about a workflow on "Keyframes and Plugins" and is written by DeJay as a post in our forum. See if it is okay. @Dejay I've made minor changes, see if they work for you. If you have other changes or additions let me know. In addition to the .tex files I also attach the .txt file for everyone to read and review.

Fwd: [Libav-user] Creating Panned MP3 Clips
by Andrew Randrianasulu 01 Jan '23

01 Jan '23

---------- Forwarded message --------- От: Terry Corbet <tcorbet(a)ix.netcom.com> Date: вс, 1 янв. 2023 г., 09:10 Subject: [Libav-user] Creating Panned MP3 Clips To: <libav-user(a)ffmpeg.org> I have recently discovered how to use the Audacity Envelope Tool to turn a standard stereo MP3 file into a modified one in which throughout the entire duration of the clip the apparent source of the sounds will traverse from left to right. While I could use that workflow to manually perform the same transformation on multiple files, for my own use as well as to help other family members [who generally have limited computer skills] I want to automate that workflow. Over the past four days I have played as much catch-up on the many topics and toolkits which appear might permit me to engineer a software solution to this requirement. As a newbie, I probably will not correctly summarize what I believe to be the possible tools and approaches, so please forgive any misuse to the correct terminology. I hope/believe that I might be able to state my concepts/questions in a manner which will be most considerate of the time of those who participate in this mailing list and most quickly help me move closer to a good approach to the challenge. 01. I have managed to download the libraries which are used for the maintenance of the ffmpeg, ffprobe and ffplay triumvirate of tools. 02. I have managed to successfully build some sample C programs [taken from the doc\examples sub-directory and other miscellaneous snippets found by following the wonderful links from your Wiki] using the CodeBlocks IDE framework. 03. I have squirreled my way through the parts of the Doxygen documentation which seem like they would be most apropos. What I did not discover was any functions or examples of what I assumed I would be needing to do, which essential would be to process the audio frames of the FrontLeft [FL] and FrontRight [FR] channels of coming out of a stream of packets. That caused me to think that perhaps I would find examples of that processing by searching the Audacity sources to learn when and how they use the ffmpeg libraries. And somewhere between the Audacity and FFmpeg sites I stumbled upon some sources and some documentation concerning what I suppose are two reasonable libraries devoted to "resampling" -- soxr and swr. It was about at that point that I concluded that my modification of the sampled frames probably does not fall within the ambit of what is meant by resampling at all and that led to an investigation of what Nyquist was all about. Wow, what a guy Mr. Dannenberg must be. The 2007 Nyquist Reference Manual is a jaw-dropping read. I think that is enough background/context. Here's were I would appreciate any suggestions: A. Would it be possible to accomplish the steps necessary to achieve the desired result just using ffmpeg.exe? I imagine that, using the command line tool and an appropriate shell scripting language, it might be necessary to make multiple passes of the original .mp3 file and/or the two separate channels. I am not concerned about that loss of throughput; it will always be far faster than any manual procedure. B. Nonetheless, there are some advantages that would accrue from accomplishing the work entirely in an application .exe with a little GUI glitter to help the user be able to attempt some trial-and-error [preview] with slight changes in some of the parameters of the task depending upon the nature of the audio content and the manner in which the user will eventually play the output on different devices in different environments. Since I will not have the capabilities for building an Envelope in the manner that Nyquist [Lisp] accomplishes that, can anyone point me to any sample code doing that in C with the eight ffmpeg .dll libraries? C. Or -- and I appreciate that it is not fair to ask this of this mail group -- but I would appreciate any experience/advice as to whether the solution really ought to be accomplished by some scripting and/or macro facilities wrapped around Audacity? Thank you so much for the fantastic capabilities you have provided with the entire FFmpeg effort and for your patience in reading through my questions as the bell is about to strike on the New Year. _______________________________________________ Libav-user mailing list Libav-user(a)ffmpeg.org https://ffmpeg.org/mailman/listinfo/libav-user To unsubscribe, visit link above, or email libav-user-request(a)ffmpeg.org with subject "unsubscribe".

possible aspect ratio bug with rotated videos?
by Andrew Randrianasulu 28 Dec '22

28 Dec '22

So, I looked into folders with videos recorded on my tablet sometime in last summer. Some of them naturally rotated (vertical) I found latest cingg git show them with wrong (inversed) aspect ratio until I bring up format window and doubleclick on Auto checkbox near format dropdown menus .... I just used 'cin' as program in window "Open with ..." available from context menu item by right-click on video file in konqueror filemanager ( TDE 14.0.13), effectively using cin as video player Was this bug there before? May be * I * made it while working on aspect ratio autodetect .... Something to think about outside of bluray box!

interesting use of tsmuxer, other Bluray software
by Andrew Randrianasulu 24 Dec '22

24 Dec '22

https://m.youtube.com/watch?v=76jHqjYbrbo apparently, you can "demux" srt subtitles to Blu-ray "sup" graphical subtitle stream, then edit it with bdsup2sub++ (c++/qt5 port of java-based bdsup2sup) and remux back into blu-ray! Or create dvd subtitles out of srt subtitles! Or create your your own *.ass/ssa in ageasub and then use https://github.com/Masaiki/ass2bdnxml (in theory it can give you sup file directly according to built-in help) And manipulate subtitle params with https://github.com/cubicibo/SUPer (uses python) Also, not something I tried but interesting piece of software (python again) for manipulating blu-ray internals like playlist/clip info ... https://github.com/shimamura-hougetsu/shinya Also, windows program but may work under wine? 3d (MVC) encoder (x264 can't do this) https://sites.google.com/site/videofan3d/software/frim-encoder. Also, is comment from https://www.cinelerra-gg.org/bugtracker/view.php?id=282#c3706 actually in manual somewhere? I can't see it in https://cinelerra-gg.org/download/CinelerraGG_Manual/Subtitles.html but may be it resided in some other section .... May be this advanced manipulations of Blu-ray streams also better to be put in separate html document? It really not about Cin-gg but still those pieces of info a bit hard to find so having them on our site might be attractor!

Proxy 1:1
by Andrea paz 18 Dec '22

18 Dec '22

>From an answer by IgorBeg on the forum I learn that for 1:1 proxies, if you set the "scale factor," you have double scaling: "The size of your video is scaled down of the Scale factor but, then, it is rescaled up to the project format. For example, your format project is 1920x1080 and Proxy's Scale factor is 1/4, then your videos will be scaled down to 480x270 and then up-scaled to 1920x1080. For an old computer, this option is not recommended." I put this sentence in the manual, you tell me if it is okay.

HDV with PCM audio as Blu-ray video burned to BD-RE discs
by Terje J. Hanssen 12 Dec '22

12 Dec '22

I had to troubleshoot and replace a bad SATA power connector to my internal LG Blu-ray burner that caused confusing disc mount issues and delay, before the burner device worked properly again. lsscsi | grep BD [5:0:0:0] cd/dvd HL-DT-ST BD-RE BH10LS30 1.02 /dev/sr0 So far I have tested successful burning on BD50-RE DL discs with K3b/cdrecord using a single 2GB HDV clip with PCM transcoded audio written to Blu-ray video UDF image. For HDV this time I've tested BD-RE discs from two manufacturers, Verbatim and unlabeled (dealer Slowmoose). Last year I tested also SD-Bluray video successful burned on TDK BD-RE discs. And most important, the discs starts as autoplay after loading in my Samsung UBD-K8500 Blu-ray hardware player. The quality of interlaced video and PCM audio seems for me equivalent via VLC and Samsung BD player. Testing is executed on VLC/Leap 15.4 workstation and Samsung BD-player, both connected to the same Asus 27" LCD monitor (PB2780Q), easy switchable via DP and HDMI ports respectively.
