Black output video
I use linux/Ubuntu system with EGL.
I ran the given example./ffmpeg -i media/0.mp4 -i media/1.mp4 -filter_complex gltransition -y out.mp4.
Though voice could be saved, output.mp4 shown nothing but black screen.
Would you mind help me to solve this problem?3q
segmentation fault on amazon linux
hey,
I've been trying to install on amazon linux and so far have been unsuccessful.
I'm following the EGL instructions.
From what I understood the requirements are:
-
glvnd1.0 (from source)
./autogen.sh
./configure --prefix="$HOME/ffmpeg_build"
make
make install -
mesaGL>=1.7 mesaGLU>=1.7
yum install mesa-libGLU mesa-libGLU-devel -
GLEW >=2.0 (from source)
make SYSTEM=linux-egl GLEW_DEST="$HOME/ffmpeg_build"
make install
For ffmpeg I installed the libs required to build with libx264 (following the steps on https://trac.ffmpeg.org/wiki/CompilationGuide/Centos)
PKG_CONFIG_PATH="$HOME/ffmpeg_build/lib/pkgconfig" ./configure --prefix="$HOME/ffmpeg_build" --extra-cflags="-I$HOME/ffmpeg_build/include" --extra-ldflags="-L$HOME/ffmpeg_build/lib" --bindir="$HOME/bin" --enable-libx264 --enable-gpl --enable-opengl --enable-filter=gltransition --extra-libs="-lGLEW -lEGL"
This is the error I get
ffmpeg -i ../ffmpeg-gl-transition/media/0.mp4 -i ../ffmpeg-gl-transition/media/1.mp4 -filter_complex gltransition -y out.mp4

thanksrending bug for 1080*1920 resolution video
When I use gl-transition for video which ratios is 9:16 (such as 1080x1920, 720x1280, 540x960)，glsl filter rending bug，same like issues #7
ffmpeg command:

videos not concatinating with transition applied
I need to concatenate two or more videos without clipping them (with full length) and apply transition while changing the video.
I'm trying your example script on my server as
env DISPLAY=:0 ffmpeg -i s1.mp4 -i s2.mp4 -filter_compl
ex "gltransition=duration=4:offset=1.5:source=crosswarp.glsl" -y out1.mp4
Each video is of duration 30 seconds, thus the desired output should be of 60 seconds. But it generates the video of 31 seconds and the transition is applied just after 1.5 seconds of the first video.
I also tried the example from concate.sh file with 3 files having the duration of 10 seconds, 20 seconds and 5 seconds each respectively. But the video produced is of 9 seconds long with one transition applied on first video switching while there is no transition from 2nd to 3rd video switching.
How to concatenate videos with their full length and apply transition while switching/concatenating of videos?
Problems with alpha channel
I am not sure if alpha channel is not supported or if I am just doing something wrong.
If they are not supported, would it be possible to add support for it into the extension?
It's understandable to omit alpha channel for most use cases, but I would like to be able to use transitions on overlays with alpha channel.
Here's a short example of such command:
ffmpeg -i ./video/logo.png -i ./video/logo2.png -i ./video/image.jpg -filter_complex "\ [0:v]scale=w=320:h=240:force_original_aspect_ratio=1,pad=320:240:(ow-iw)/2:(oh-ih)/2:[email protected],loop=125:1:0,split[logo1_split1][logo1_split2]; \ [1:v]scale=w=320:h=240:force_original_aspect_ratio=1,pad=320:240:(ow-iw)/2:(oh-ih)/2:[email protected],loop=125:1:0,split[logo2_split1][logo2_split2]; \ [2:v]scale=w=640:h=480,setsar=sar=4/3,loop=250:1:0[image]; \ [logo1_split1]trim=1.25,setpts=PTS-STARTPTS[logo1_split1_main]; \ [logo1_split2]trim=0:1.25[logo1_split2_out]; \ [logo2_split1]trim=1.25,setpts=PTS-STARTPTS[logo2_split1_main]; \ [logo2_split2]trim=0:1.25[logo2_split2_in]; \ [logo1_split2_out][logo2_split2_in]gltransition=duration=1.25:source=/filters/crosswarp.glsl[logos_tr]; \ [logo1_split1_main][logos_tr][logo2_split1_main]concat=n=3[logos_concat]; \ [image][logos_concat]overlay " -pix_fmt yuv420p -q:v 2 -y -f mp4 logos.mp4
Using scale and pad to ensure both overlays are the same size, then repeating the process of the example for transition and finally overlaying it over the media file. However, purple from pad was showing, despite the alpha channel being set.
To check if problem is not in something else, like with the padding, I tried simplified transitionless version and it worked, the purple area was now transparent
ffmpeg -i ./video/logo.png -i ./video/logo2.png -i ./video/image.jpg -filter_complex "\ [0:v]scale=w=320:h=240:force_original_aspect_ratio=1,pad=320:240:(ow-iw)/2:(oh-ih)/2:[email protected],loop=125:1:0[logo1]; \ [1:v]scale=w=320:h=240:force_original_aspect_ratio=1,pad=320:240:(ow-iw)/2:(oh-ih)/2:[email protected],loop=125:1:0[logo2]; \ [2:v]scale=w=640:h=480,setsar=sar=4/3,loop=250:1:0[image]; \ [logo1][logo2]concat=n=2[logos_concat]; \ [image][logos_concat]overlay " -pix_fmt yuv420p -q:v 2 -y -f mp4 logos2.mp4
Patch does not apply
Running the command (On OSX) "git apply ~/ffmpeg-gl-transition/ffmpeg.diff" returns this error:
Checking patch libavfilter/Makefile... Hunk #1 succeeded at 367 (offset 15 lines). Checking patch libavfilter/allfilters.c... error: while searching for: REGISTER_FILTER(ZMQ, zmq, vf); REGISTER_FILTER(ZOOMPAN, zoompan, vf); REGISTER_FILTER(ZSCALE, zscale, vf); REGISTER_FILTER(ALLRGB, allrgb, vsrc); REGISTER_FILTER(ALLYUV, allyuv, vsrc); error: patch failed: libavfilter/allfilters.c:360 error: libavfilter/allfilters.c: patch does not apply
*Edited: Verbose version attached.
Is anything up with this plugin and the newst ffmpeg, making this not work anymore?
When trying to build after the command has failed, the follow message appears in the config.log file in ffmpeg.

can only use a few GL Transitions
Hi, i successfully managed to use the following transitions:
- crosswarp
- cube
- Butterflywavescrawler
- circlecrop
- circle
- simplezoom
- InvertedPageCurl
- Dreamy
- Mosaic
- DreamyZoom
- doorway
- fadecolor
- rotate_scale_fade
- swap
but if i want to use any others, and i do, the video gets rendered but there is no visual transition, i get back the original video concatenated without effects.
Can you point me in any direction ?
Thank you
ques for transition
I make the ffmpeg successfully,but I meet the problems "Error initializing filter 'gltransition' Error initializing complex filters. Operation not permitted" when I call the command“./ffmpeg -i media/0.mp4 -i media/1.mp4 -filter_complex gltransition -y out.mp4”.
Then I install the xvfb,export DISPLAY=localhost:1.0,another error occurs when the code call glCreateShader:"X Error of failed request: BadRequest (invalid request code or no such operation)".
I have little experience with OpenGL issues over remote connections.My glxinfo is:
display: localhost:1 screen: 0
direct rendering: No (If you want to find out why, try setting LIBGL_DEBUG=verbose)
server glx vendor string: SGI
server glx version string: 1.4
OpenGL vendor string: Mesa Project
OpenGL renderer string: Software Rasterizer
OpenGL version string: 1.4 (2.1 Mesa 7.11)
Can you give me some help?Thank you!
how do i use it on windows
Dockerile build fail
no editing, Dockerfile just build fail. It's seems like ffmpeg complie error.
I tried to modify the Dockerfile to the following version. and it build succeed.
But when I run ffmpeg -v 0 -filters | grep gltransition
returned T.. gltransition VV->V (null). Seems different from others.
and run ffmpeg -i pic.jpg -filter_complex gltransition -y out.mp4
returned
[AVFilterGraph @ 0x55f6264ddac0] Error initializing filter 'gltransition' with args 'offset=0.5:duration=0.5:source=/tmp/gl-transition/ffmpeg-gl-transition/gl-transitions/transitions/burn.glsl'

rendering bug for some aspect ratios
There's currently an bug where some video dimensions result in warped, funky-looking transitions.
I'm not sure exactly what the bug is, but my best guess is that it has to do with how AVFrame represents its frame data. It seems that AVFrame adds padding to each line to maximize use of SIMD. We're definitely not accounting for this padding, and I think that's what's causing the issue for some video sizes.
Adding this here to track progress.

Is there any better way to make a build or get inbuild gl-transition ffmpeg?
[bug] vertical coordinate is inverted from gl-transition expectations
The vertical (y) coordinate appears to be inverted: For example, the heart.glsl transition draws an upside-down heart.
FreeBSD build instructions
Hi,
it's taking me some hours now and I can't get ffmpeg to compile with ffmpeg-gl-transitions on FreeBSD. Did someone succeed and can you share some instructions in what you did?
How to use this with images rather than videos
I'd like to make this compatible with https://github.com/h2non/videoshow, any suggestion?
How Modify So Videos Remain Origin Length With Audio?
Using the example ffmpeg from this source. How can I modify it so it does not remove the audio and trim the video file lengths to 3 seconds? I already have the videos at the correct length.

ffmpeg compilation error
Hi,
Following your instructions on how to build ffmpeg I have encountered an error while running the ./configure command I am getting the following error.
./configure --enable-libx264 --enable-gpl --enable-opengl --enable-filter=gltransition --extra-libs='-
lGLEW -lglfw'
gcc is unable to create an executable file.
If gcc is a cross-compiler, use the --enable-cross-compile option.
Only do this if you know what cross compiling means.
C compiler test failed.If you think configure made a mistake, make sure you are using the latest
version from Git. If the latest version fails, report the problem to the
[email protected] mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "ffbuild/config.log" produced by configure as this will help
solve the problem.
I am running the build from Windows os, my c compiler is configured and present on PATH, I am able to run ./configure successfully without the parameters.

Crash invalid vertex shader, built for Android
Hello,
Finally, I was able to build the library for Android (I needed to change some includes in the vf_gltransition.c) and using this wrapper I can run the ffmpeg using the command line options.
So before I added this library the FFmpeg was working fine, in fact, the FFmpeg is working fine, but when I try to use some of the Transition features it crashes.
Here the crash for: ffmpeg -i path-to/0.mp4 -i path-to/1.mp4 -filter_complex gltransition -y out.mp4
Press [q] to stop, [?] for help

Attached you'll find a zip that contains two files:

Note: I just tried to build for arm64-v8a

Ffmpeg fails with "Segmentation fault (core dumped)"
I followed your instruction and build the ffmpeg in my Ubuntu 16.04 server. I used "Linux with EGL" option. Everything went well and the build was successful.
Then I ran this command with the sample file you gave,
ffmpeg -loglevel debug -i media/0.mp4 -i media/1.mp4 -filter_complex gltransition -y out.mp4
It failed with "Segmentation fault (core dumped)" error and here is the debug log,

For example, I would like to integrate this repo into an FFMPEG tutorial, is there anyway I can do it?
iOS compatibility
Hi, I'm using react-native-ffmpeg. Do you think there's any way of building ffmpeg for iOS with gl-transition filter? If so, can you point me in the direction of how to do it?

concat.sh example has a problem
https://github.com/transitive-bullshit/ffmpeg-gl-transition/blob/master/concat.sh
There are 3 input videos, each of them are 4.00 seconds long.
That means we have 2 transitions. And, each transition is set to 1 second.
The total duration of out.mp4 should be (3 videos * 4 seconds) = 12 seconds.
Instead, the output from concat.sh is 10 seconds long, meaning we have shortened the video.
This doesn't make sense -- transitions logically aren't supposed to reduce the video duration.
Ping @transitive-bullshit
Hi guys, I need some video transitions effects to use in my Android app
Could you tell me how can I compile FFmpeg with ffmpeg-gl-transition ? Has anybody done something like this before?
Thanks.

Bug - Segmantation Error with gltransition
Hello,
I have spent several hours working on this now, and each time I rebuild ffmpeg, it results in a segmentation fault when I attempt to use the filter:
root@host:[/usr/local/src/ffmpeg-latest]: /usr/local/bin/ffmpeg -i /home/procserverjh/public_html/videosly/video/ikl3tkm_ez.mp4 -i /home/procserverjh/public_html/videosly/video/u5e9f3y_ez.mp4 -filter_complex gltransition -y /home/procserverjh/public_html/videosly/video/out.mp4
...
Stream mapping:
Stream #0:0 (h264) -> gltransition:from (graph 0)
Stream #1:0 (h264) -> gltransition:to (graph 0)
gltransition (graph 0) -> Stream #0:0 (libx264)
Stream #0:1 -> #0:1 (aac (native) -> aac (native))
Press [q] to stop, [?] for help
Segmentation fault (core dumped)
This only occurs when I use the gltransition filter. If I remove that option from the processing command, or use a different filter, the output completes successfully.
I have tried rebuilding using different versions of the ffmpeg source, as well as installing various different components needed to compile it. At this point, I am unable to determine the cause of the segfault with the gltransition filter.
[bug] multiple transitions not taking effect in single filter chain
I would like to patch together three segments, and use one type of transition between the first and the second, and another one between the second and the third.
This appears to be impossible. The last "source=" command determines the transition being used for each occurrence of the filter.
EXAMPLE:
ffmpeg
-i file1.mp4
-i file2.mp4
-filter_complex "

This code will result in luma.glsl being applied to both transitions.

Hello Guys
Need a quick help here.
I have build this to be used in js environment.

But on runtime I am getting error as
glReadPixels: format and type incompatible with the current read framebuffer
How can I debug it?
No such filter: 'gltransition'
I installed the dependencies for FFMPEG build(GLU,GLFW,GLVND & GLEW libs) and configured it with EGL.
My configured command is:
./configure --enable-gpl --enable-opengl --enable-filter=gltransition --extra-ldflags="-L/usr/lib/x86_64-linux-gnu -L/usr/local" --extra-libs='-lGLEW -lglfw3 -lEGL -lGLU' --enable-shared --enable-static
After executing this command in Enabled Filter log GLTransition filter is there.
Then I checked for GLTransition filter using command:
./ffmpeg -v 0 -filters | grep gltransition
but it shows nothing.
Then also cross checked using ffmpeg command below:
./ffmpeg -i media/0.mp4 -i media/1.mp4 -filter_complex gltransition -y out.mp4
but it shows error like,
[AVFilterGraph @ 0x1febe80] No such filter: 'gltransition'
Error initializing complex filters.
Invalid argument.
Am I missed something?

C compiler test failed
I have installed FFmpeg in Ubuntu system by building from source and the version installed is
ffmpeg version 3.2.2-2~16.04.york0 Copyright (c) 2000-2016 the FFmpeg developers
built with gcc 5.4.1 (Ubuntu 5.4.1-4ubuntu1~16.04.york1) 20161202
I tried installing this library from the beginning as given in the instruction by cloning FFmpeg from git and all.
While running
./configure --enable-libx264 --enable-gpl --enable-opengl \
--enable-filter=gltransition --extra-libs='-lGLEW -lglfw'
I'm getting the error as C compiler test failed
gcc is unable to create an executable file.
If gcc is a cross-compiler, use the --enable-cross-compile option.
Only do this if you know what cross compiling means.
C compiler test failed.
If you think configure made a mistake, make sure you are using the latest
version from Git. If the latest version fails, report the problem to the
[email protected] mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "ffbuild/config.log" produced by configure as this will help
solve the problem.
How to solve this problem?
how to find also other similar wonderfull transitions?
Are there other wonderfull transitions like this one? Because the https://www.mltframework.org/ transitions doesn't looks so cute..

The libavfilter/allfilters.c is there, so I am not sure what the problem is here.
I am new to patching with git... any advice?
