Interlace driving me mad .....

So, I grep'ed ffmpeg-4.3 sources and apparently thise falgs consumed by few encoders outside of mpeg2/4: guest@slax:/dev/shm/cinelerra/cinelerra-5.1/cinelerra$ grep 'AV_CODEC_FLAG_INTERLACED_DCT' ../thirdparty/ffmpeg-4.3/libav libavcodec/ libavdevice/ libavfilter/ libavformat/ libavresample/ libavutil/ guest@slax:/dev/shm/cinelerra/cinelerra-5.1/cinelerra$ grep 'AV_CODEC_FLAG_INTERLACED_DCT' ../thirdparty/ffmpeg-4.3/libavcodec/*.c ../thirdparty/ffmpeg-4.3/libavcodec/cuviddec.c: avctx->flags |= AV_CODEC_FLAG_INTERLACED_DCT; ../thirdparty/ffmpeg-4.3/libavcodec/cuviddec.c: avctx->flags &= ~AV_CODEC_FLAG_INTERLACED_DCT; ../thirdparty/ffmpeg-4.3/libavcodec/dnxhddata.c: interlaced == !!(avctx->flags & AV_CODEC_FLAG_INTERLACED_DCT) && ../thirdparty/ffmpeg-4.3/libavcodec/dnxhdenc.c: if (avctx->flags & AV_CODEC_FLAG_INTERLACED_DCT) { ../thirdparty/ffmpeg-4.3/libavcodec/dvenc.c: if (s->avctx->flags & AV_CODEC_FLAG_INTERLACED_DCT) { ../thirdparty/ffmpeg-4.3/libavcodec/libx264.c: x4->params.b_interlaced = avctx->flags & AV_CODEC_FLAG_INTERLACED_DCT; ../thirdparty/ffmpeg-4.3/libavcodec/libxavs.c: x4->params.b_interlaced = avctx->flags & AV_CODEC_FLAG_INTERLACED_DCT; ../thirdparty/ffmpeg-4.3/libavcodec/mpegvideo_enc.c: if ((s->avctx->flags & (AV_CODEC_FLAG_INTERLACED_DCT | AV_CODEC_FLAG_INTERLACED_ME)) && ../thirdparty/ffmpeg-4.3/libavcodec/mpegvideo_enc.c: s->progressive_sequence = !(avctx->flags & (AV_CODEC_FLAG_INTERLACED_DCT | ../thirdparty/ffmpeg-4.3/libavcodec/mpegvideo_enc.c: if (s->avctx->flags & AV_CODEC_FLAG_INTERLACED_DCT) { ../thirdparty/ffmpeg-4.3/libavcodec/mpegvideo_enc.c: if (s->avctx->flags & AV_CODEC_FLAG_INTERLACED_DCT) { ../thirdparty/ffmpeg-4.3/libavcodec/nvenc.c: if (ret < 1 && avctx->flags & AV_CODEC_FLAG_INTERLACED_DCT) { ../thirdparty/ffmpeg-4.3/libavcodec/nvenc.c: if (avctx->flags & AV_CODEC_FLAG_INTERLACED_DCT) { ../thirdparty/ffmpeg-4.3/libavcodec/nvenc.c: if (avctx->flags & AV_CODEC_FLAG_INTERLACED_DCT) { ../thirdparty/ffmpeg-4.3/libavcodec/pngenc.c: s->is_progressive = !!(avctx->flags & AV_CODEC_FLAG_INTERLACED_DCT); ../thirdparty/ffmpeg-4.3/libavcodec/proresenc_anatoliy.c: ctx->is_interlaced = !!(avctx->flags & AV_CODEC_FLAG_INTERLACED_DCT); ../thirdparty/ffmpeg-4.3/libavcodec/proresenc_kostya.c: if (avctx->flags & AV_CODEC_FLAG_INTERLACED_DCT) ../thirdparty/ffmpeg-4.3/libavcodec/proresenc_kostya.c: int interlaced = !!(avctx->flags & AV_CODEC_FLAG_INTERLACED_DCT); ../thirdparty/ffmpeg-4.3/libavcodec/qsvenc.c: if (avctx->flags & AV_CODEC_FLAG_INTERLACED_DCT) { guest@slax:/dev/shm/cinelerra/cinelerra-5.1/cinelerra$ grep 'AV_CODEC_FLAG_INTERLACED_ME' ../thirdparty/ffmpeg-4.3/libavcodec/*.c ../thirdparty/ffmpeg-4.3/libavcodec/huffyuvenc.c: s->interlaced = avctx->flags & AV_CODEC_FLAG_INTERLACED_ME ? 1 : 0; ../thirdparty/ffmpeg-4.3/libavcodec/motion_est.c: if ((s->avctx->flags & AV_CODEC_FLAG_INTERLACED_ME) ../thirdparty/ffmpeg-4.3/libavcodec/motion_est.c: if ((s->avctx->flags & AV_CODEC_FLAG_INTERLACED_ME) ../thirdparty/ffmpeg-4.3/libavcodec/motion_est.c: if (s->avctx->flags & AV_CODEC_FLAG_INTERLACED_ME) { ../thirdparty/ffmpeg-4.3/libavcodec/mpegvideo.c: (s->avctx->flags & AV_CODEC_FLAG_INTERLACED_ME)) { ../thirdparty/ffmpeg-4.3/libavcodec/mpegvideo_enc.c: if ((s->avctx->flags & (AV_CODEC_FLAG_INTERLACED_DCT | AV_CODEC_FLAG_INTERLACED_ME)) && ../thirdparty/ffmpeg-4.3/libavcodec/mpegvideo_enc.c: AV_CODEC_FLAG_INTERLACED_ME) || ../thirdparty/ffmpeg-4.3/libavcodec/mpegvideo_enc.c: if (s->avctx->flags & AV_CODEC_FLAG_INTERLACED_ME) { ../thirdparty/ffmpeg-4.3/libavcodec/mpegvideo_enc.c: if (s->avctx->flags & AV_CODEC_FLAG_INTERLACED_ME) { ../thirdparty/ffmpeg-4.3/libavcodec/mpegvideo_enc.c: if (s->avctx->flags & AV_CODEC_FLAG_INTERLACED_ME) { So, reworked this section again ... basically only excluding mjpeg codec case from setting those flags, instead of whilelisting mpeg2/4 only Strangely ffv1/avi shows interlace (with my patch) if source was Top Field First and not showing it if source was Bottom Field First ..:/ dv file re-encoded as dv_ntsc.avi shows bff correctly, it seems. mp4 container with h264 also gets it right now .... mpeg2 works (but not sure if field order correct or now ..I'm confused by ffmpeg source :/) mkv seems to work (but it was working before) https://cloud.mail.ru/public/5AM1/275yC576u How to test those 'tb/bb/tt/bt' cases?

Backup in CinGG
by Andrea paz 12 Feb '21

12 Feb '21

I was thinking of adding a section in the manual about how backup works in CinGG. Please correct me if I am wrong: if I don't enable the new option (default), a backup is created at each editing action (see below the list of actions suggested by Andràs) but this overwrites the previous backup.prev so in .bcast5 there will be only one backup file (plus backup.xml whose function I don't understand). The same when we manually create a backup via File --> save backup. When we make a File --> Load backup, in addition to bring on the timeline the backup.prev we also create a new backup.prev. If I enable "Autosaves continuous backups" the backup.prev file is not overwritten, but a new backup.prev_xxxxxxxx_xxxxxx (with data and clock time) is created. These are small files so their number is not a problem. In any case when you exit CinGG the various backups are deleted except for the last 50, which will still be available at the next restart. The new option is put in Settings --> Preferences --> Appearance Tab under the Dangerous section because if you have a crash or anyway you don't exit CinGG correctly, the delete phase doesn't happen and the risk is the increase of the backup files inside .bcast5 but, as said, their size is very small and so not a big problem. With this option enabled, how does File --> save/load backup work? Is there anything I didn't understand? Is there anything to add? There are a few parts where save_backup() is called (Reuss Andràs): cinelerra/cwindowgui.C:2 cinelerra/swindow.C:1 cinelerra/keyframepopup.C:2 cinelerra/pluginpopup.C:1 cinelerra/mwindowedit.C:87 cinelerra/presetsgui.C.sav1:1 cinelerra/assetpopup.C:1 cinelerra/cwindowtool.C:1 cinelerra/render.C:1 cinelerra/setformat.C:1 cinelerra/mwindow.C:9 cinelerra/keyframegui.C:2 cinelerra/mwindowgui.C:1 cinelerra/mainmenu.C:1 cinelerra/loadfile.C:2 cinelerra/savefile.C:2 cinelerra/menueffects.C:1 cinelerra/main.C:1 cinelerra/presetsgui.C.sav:1 cinelerra/record.C:1 cinelerra/plugindialog.C:1

AppImage for CinelerraGG testing
by Phyllis Smith 12 Feb '21

12 Feb '21

MatN has provided all of the ground work to make an AppImage for CinelerraGG. I have followed the instructions he provided and there are now 2 versions for testing. I only did very minimal testing to load a file. Files are at: https://cinelerra-gg.org/download/testing/ cin_for_older_distros.AppImage - built on Ubuntu 16 (kernel 4.4, I think) cin_for_newer_distros.AppImage - built on Fedora 32 (kernel 5.8, I think) After downloading you will have to change the mode for execution (chmod +x cin_for_older_distros.AppImage) For appimage, the build is supposed to be done on the lowest version distro because otherwise newer libraries might be missing. For example, I tried running cin_for_newer_distros.AppImage on ubuntu 16 and GLIBC version xxx.xxx was not available.

automatic save of
by Reuss András 08 Feb '21

08 Feb '21

Hi I read sometimes cinelerra mail list (not very carefully) and someone once asked for an automatic backup with timestamp or something like that. I created a small patch that would provide this: on save_backup() call, a new version with timestamp is created from backup.prev. I don't know if it is useful at all. It compiles at least, but I cannot test it because cinelerra stops at start due to some missing theme plugin, did not investigate it. Thanks for your attention. Br Andras

Resolution for "help - ?" key in Batch Render Menu
by Phyllis Smith 05 Feb '21

05 Feb '21

(Rather than continuing old discussions over different emails, starting a new thread of moderation). GIT checkin of the "help" key addition to the BatchRender menu is complete with 10 language translations for the Quick Start by RafaMar. I had to do a lot of testing today to try to make sure there are no hangs, but I could have missed something so hopefully there are no problems. Some notes follow: 1) Most likely only new or occasional users will need to take advantage of the help so there is no impact to the majority of people. Especially since with the fast computers these days, Batch Render is considered to be more of an advanced feature. 2) The majority of people using the help key will already have a browser up in another window. But* if no browser is already up*: a) the following message: ###!!! [Parent][RunMessage] Error: Channel closing: too late to send/recv, messages will be lost may come up in a terminal window as an informational message as you "browse" around, but should have no effect on Cinelerra. b) the following message: [Child 8939, MediaDecoderStateMachine #2] WARNING: Decoder=7f2eba25cc00 Decode error: NS_ERROR_DOM_MEDIA_*FATAL*_ERR (0x806e0005): file /builddir/build/BUILD/firefox-81.0.2/dom/media/MediaDecoderStateMachine.cpp, line 3470 may come up in a terminal window as an informational message as you "browse" around, but should have no effect on Cinelerra. I tracked this down in my situation to YouTube videos using newer plugins that I did not have hooked up to my browser which would not play and instead just said "Something went wrong". So basically, error messages that were probably there all along but you just did not see, might now be visible. To clear up and get no more of these messages, you can quit out of Cinelerra and then take the browser down and bring it back up as you normally would -- at least this is what worked for me. -------------------------------------- Note to *Andrea*: if you have a chance to confirm the above, that would be highly appreciated. Note to *Walter*: there really is the possibility of a hang in Cinelerra where the user could lose work so xdg-open instead of the environment variable had to be used. This was true of firefox which is the only browser I tested. All of the Shell Commands continue to use CIN_BROWSER and I could not get any hang with the same usage there. Most likely you will not need to use the Batch Render help key anyway. ------------------------------------- I am moving back to test "multiple backups" as provided by Andras and Andrew. Then hopefully the library upgrade as Andrew wrote about a few days ago.

[PATCH] [buildsystem] patch for building nasm 2.14.02 as thirdparty app
by Andrew Randrianasulu 04 Feb '21

04 Feb '21

This patch adds in somewhat hackish way support for building nasm as part of thirdparty/ tree, combined with earlier openjpeg-2.4.0 patch. It worked without autgen.sh on my machine, but if you use github [0] tarballs ./autogen.sh step is needed. Also, dav1d-0.5.1 patch hardcoded nasm path to /usr/bin/nasm I un-hardcoded it, so it actually can be build with newly-compiled nasm ... seems to work on Ubuntu 16.04.7 amd64 ? At least simple ./configure doesn't fail in dav1d dir .... [0] https://github.com/netwide-assembler/nasm/archive/nasm-2.14.02.tar.gz also you can get xz traball from https://sources.voidlinux-ppc.org/nasm-2.14.02/ {one can wonder why one need x86 asm on PPC, but may be for cross-compiling}

2 little issue
by Andrea paz 03 Feb '21

03 Feb '21

Starting CinGG from the terminal I often see this string (not always): ###!!! [Parent][RunMessage] Error: Channel closing: too late to send/recv, messages will be lost Does anyone have any idea what this means? Another problem is that recently, when I compile CinGG from git, the autogen.sh step produces a lot of warnings and asks me to use "autoupdate". After using autoupdate everything works fine and I can go on with autogen.sh, configure, etc. I always use the same commands to compile (I do a copy/paste) and only lately it gives me this problem. Andrew had said it was a directory level issue, but I'm not knowledgeable to understand what that means or how to fix it. Do you know how to fix it? I bring back the exact instructions I use: " git clone --depth 1 "git://git.cinelerra-gg.org/goodguy/cinelerra.git" cinelerra5 cd /home/paz/cinelerra5/cinelerra-5.1 ./autogen.sh ./configure --with-single-user --with-booby make 2>&1 | tee /tmp/cin5.log && make install "
