Fossies - software archive

I wonder if we should add CinelerraGG into it? so far only Cinelerra 7.3 actually there (but it provides some autogenerated software documentation?) https://fossies.org/search/linux/misc?q=folder_search&ml=25&q1=cinelerra&q2… https://fossies.org/dox/cinelerra-7.3-src/adeviceprefs_8C.html for example.. might be useful for more real (experienced) programmers? ps: not sure if 7.3 can be called Community edition now?

Wayland

I'm trying wayland and CinGG opens a warning window when I load a project; see image. Everything works fine and there are no messages at the terminal, but I was wondering if it does it to you too.

Test rendering whit x265
by Andrea paz 17 Aug '21

17 Aug '21

I did some tests with the new and old x265. I report some data, while the terminal output is attached in test-x265.txt. I used a 5 min video in h264 4.2.0 but good quality. Size= 471 MB. x265-10bit: CPU 50-80% (multithread) 27.5 fps file size 46 MB x265-12bit: CPU 50-80% (multi) 25.5 fps file size 45 MB x265-Hi: CPU 80-90% (multi) 10.6 fps file size 1.7 GB x265-Lo(w): CPU 40-70% (single/multi) 34 fps file size 67.5 MB HEVC-vaapi CPU 0-50% (single) 85.8 fps file size 117 MB (I could not see the GPU engagement) Only in x265-lo do I perceive a small decay in quality compared to the original. All others are comparable. For me a great news (thanks Andrew!) is the exploitation of multithread; on the terminal you can read the sentence: "Thread pool created using 16 threads" I have a CPU 8c/16t. The only thing I regret is that the new x265 drivers introduce a CinGG build delay of 15 min. Before my entire compile was 5 min, now it's 20 min.

variable fast/slow playback speed hack
by Andrew Randrianasulu 11 Aug '21

11 Aug '21

so i wondered if changing speed for fast/slow reverse and normal playback was possible.. after few hours of hacking I made this patch. it makes fast/slow playback speed configurable in Cinelerra_rc via new stored variables: ===j LOADPREVIOUS16 /data/data/com.termux/files/home/LibRaw/RAW_CANON_G1.CRW LOADPREVIOUS17 /data/data/com.termux/files/home/av1-cpu5-crf10.mkv SLOW_SPEED 5.000000e-01 FAST_SPEED 4.000000e+00 here I set fast playback speed to 4x, while slow_playback default remain at 0.5 .... no gui yet because I am still unsure about gui elements but I had idea about putting two input boxes in Preferences for this.. but I can be wrong with my hacking....

Fwd: in/out point selected plugin attach fix?
by Phyllis Smith 11 Aug '21

For some reason, my reply only went to Andrew so am forwarding it correctly. ---------- Forwarded message --------- From: Phyllis Smith <phylsmith2017(a)gmail.com> Date: Sun, Aug 8, 2021 at 7:52 PM Subject: Re: in/out point selected plugin attach fix? To: Andrew Randrianasulu <randrianasulu(a)gmail.com> Andrew, forgot to respond to the following: again, I wonder why it was noted by Phyllis "but making it a Preference is > not > a good idea.". Just because our Preferences a bit crowded already? > In the past, we have gotten into trouble when the Preferences window got bigger on some smaller monitors. A goal has always been to have Cinelerra continue to work on lesser hardware (which is one of the reasons proxy exists). What was happening is that the Preferences menu on a small monitor was cut off at the bottom and so there was no way for the user to click OK, Apply, or Cancel ! so the user was stuck. There is a minimum size for this window and adding more Preferences in the Appearance tab causes problems if it does not fit while still "looking good". So at this time it is very important to save room in Preferences for the really necessary things.

I will try to see if I can figure out what it is for but it also may be lost to the sands of time.
