End of flash, is there any other format?
by Kirtomy 31 Dec '20

31 Dec '20

Dear friends, we are running a small Socialengine forum since years and we uploaded videos which were converted by FFmpeg version 0.6.5. The path is shown as /usr/local/bin/ffmpeg. Our provider cannot help us, so what can we do to get uploaded videos converted to mp4 or avi, they are all converted to flv which will be no longer supported. Thanks for your help Sally Kirtomy

Decimate question
by Mark Filipak (ffmpeg) 30 Dec '20

30 Dec '20

Decimate will drop a repeated frame in each sequence of 5 (=default) frames. I assume the dropped frame can be any 1 of the 5. Is there a way to discover which of the 5 frames it dropped? Thanks for your attention. Be happy, be healthy, be safe.

Ynt: Mailman privacy alert

Hi, I have 8 minutes and 51 seconds of video recording (30 fps). Although the total image is 532, it turns out to be 533. ffmpeg -i 1.MP4 -c:v mpeg4 -q:v 2.0 -vsync 0 -an 2.MP4 I converted it to cfr format using this code.The result has not changed. Also, while dividing the video into frames, the first frame of the first second is taken or is it the 30th image? Best Regards, Mert. Arş.Gör.

How to properly escape a literal comma ", " in drawtext filter text?
by Steven Kan 29 Dec '20

29 Dec '20

I am attempting to overlay the text, “Room Temp Water, No Heat Mat” onto some video. If I use that exact string, the comma renders as a white box. According to the drawtext documentation, I should escape the comma, but depending on the context I may have to escape the escape character before the comma, etc. Values from 0 to 7 escape slashes do not work, as they each result in a white box where I want my comma. This results in 8 white boxes: ./ffmpeg -i /Users/steven/Documents/Baking/4Up.mp4 -vf "drawtext=fontfile=/System/Library/Fonts/Keyboard.ttf: text='Room Temp Water,\,\\,\\\,\\\\,\\\\\,\\\\\\,\\\\\\\ No Heat Mat': fontcolor=white: fontsize=24: box=1: boxcolor=black(a)0.5: boxborderw=5: x=(w-text_w)*0.05: y=(h-text_h)*0.05" -c:v libx264 /Users/steven/Documents/Baking/TextwOverlay.mp4 What is the proper way to insert a literal comma into the text argument of drawtext? Or should I continue adding slashes until it works? ;-) Thanks!

Screenrecording bound to a certain window & desktop ?
by tuxic＠posteo.de 29 Dec '20

29 Dec '20

Hi, (I am using GENTOO Linux and X11/openbox and a NVidia GeForce RTX 2060 SUPER graphics card.) I want to use ffmpeg for screenrecording (beside other tings of course...) Currently I need to stay on the certain desktop, which I currentlu recording. Is it possible somehow, to "lock" ffmpeg to a certain desktop and a certain window while recording in a way, that I am allowed to work on another window and another application's window while recording whithout corrupting the result of that recording? And if yes: How can I accieve this? Cheers! mcc

simple bob -- How?
by Mark Filipak (ffmpeg) 29 Dec '20

29 Dec '20

I seek a way to do simple bob (i.e. repeat fields at 2xFPS) with no other filtering. Can you help me? I suppose I could do something like this: -filter_complex "split[s1][s2],[s1]separatefields[A1][a1],[s2]separatefields[A2][a2],[A1][A2]weave[Ao],[a1][a2]weave[ao],[Ao][ao]merge" (Kindly forgive any mistakes -- I haven't done anything like this in a couple of months.) But I thought I'd ask here for an easier way. These gave pretty good results. They're listed from best to worst: bwdif yadif=send_field_nospatial yadif=send_field However, I suspect that, in addition to mechanical frame changes, they're also making some (unwanted) cosmetic changes. Based on what's written in the documention, these seemed promising: separatefields,doubleweave separatefields,tinterlace=mergex2 But they produced surprising and undesired results. Optional Reading: I also tried this: separatefields,select=eq(mod(n,4),0)+eq(mod(n,4),3),weave It's not what I actually want, but I tried it because it doesn't make sense to me -- weave together fields N%4==0 and N%4==3? (Really? Modulo-4? fields 0 & 3?) -- so, because it doesn't make sense to me, I thought I might learn something interesting. So, what happened? "Conversion failed!" is what happened. Why it's cited as an example (https://ffmpeg.org/ffmpeg-filters.html#Examples-121) in the documentation is a mystery to me.

Decimation with ppsrc=1 malfunctions

Decimation with ppsrc=1 malfunctions. Paul fixed this somewhat, but it's still in trouble. Since I eliminated threading and decimation as the cause, I suspect that frames numbers are being bollixed. The report package is here: https://www.dropbox.com/t/zu4cezneCJIsdmUu Expires Jan 2, 2021.

ffplay - Hikvision RTSP stream on Wan
by Moty.Hevroni 28 Dec '20

28 Dec '20

Dear ffmpeg support team, I would like to get your opinion on a problem that occurs when trying to open RTSP streams, of our cameras (Hikvision) via Wan: When accessing the camera within the LAN, by command: (ffplay -i rtsp://admin:pass@192.168.1.40/streaming/channels/101/) The connection is working properly and the video window pop-up automatically. So I connected the camera to a separate router, with proper port-forwarding (554 TCP + UDP), then I tried to access it true WAN by command: (ffplay -loglevel debug -i rtsp://admin:Test1234@195.133.154.12/streaming/channels/101/), and the following error occurred: (Note: VLC worked fine in both LAN and WAN) root@kali:~# ffplay -loglevel debug -i rtsp://admin:Test1234@195.133.154.12/streaming/channels/101/ ffplay version 4.3.1-5 Copyright (c) 2003-2020 the FFmpeg developers built with gcc 10 (Debian 10.2.0-15) configuration: --prefix=/usr --extra-version=5 --toolchain=hardened --libdir=/usr/lib/x86_64-linux-gnu --incdir=/usr/include/x86_64-linux-gnu --arch=amd64 --enable-gpl --disable-stripping --enable-avresample --disable-filter=resample --enable-gnutls --enable-ladspa --enable-libaom --enable-libass --enable-libbluray --enable-libbs2b --enable-libcaca --enable-libcdio --enable-libcodec2 --enable-libdav1d --enable-libflite --enable-libfontconfig --enable-libfreetype --enable-libfribidi --enable-libgme --enable-libgsm --enable-libjack --enable-libmp3lame --enable-libmysofa --enable-libopenjpeg --enable-libopenmpt --enable-libopus --enable-libpulse --enable-librabbitmq --enable-librsvg --enable-librubberband --enable-libshine --enable-libsnappy --enable-libsoxr --enable-libspeex --disable-libsrt --enable-libssh --enable-libtheora --enable-libtwolame --enable-libvidstab --enable-libvorbis --enable-libvpx --enable-libwavpack --enable-libwebp --enable-libx265 --enable-libxml2 --enable-libxvid --enable-libzmq --enable-libzvbi --enable-lv2 --enable-omx --enable-openal --enable-opencl --enable-opengl --enable-sdl2 --enable-pocketsphinx --enable-libmfx --enable-libdc1394 --enable-libdrm --enable-libiec61883 --enable-chromaprint --enable-frei0r --enable-libx264 --enable-shared libavutil 56. 51.100 / 56. 51.100 libavcodec 58. 91.100 / 58. 91.100 libavformat 58. 45.100 / 58. 45.100 libavdevice 58. 10.100 / 58. 10.100 libavfilter 7. 85.100 / 7. 85.100 libavresample 4. 0. 0 / 4. 0. 0 libswscale 5. 7.100 / 5. 7.100 libswresample 3. 7.100 / 3. 7.100 libpostproc 55. 7.100 / 55. 7.100 Initialized opengl renderer.
