How to add custom configure option with VCPKG when building FFMPEG ?
1er novembre 2024, par NickWuzhDoes anyone know how to enable x11grab format in FFMPEG with VCPKG ?


I'm building FFMPEG in vcpkg manifest mode. Here is my vcpkg.json :


{
 "name": "project",
 "version": "1.0.0",
 "dependencies": [
 {
 "name": "ffmpeg",
 "features": [
 "avcodec",
 "avdevice",
 "avfilter",
 "avformat",
 "bzip2",
 "ffmpeg",
 "lzma",
 "postproc",
 "swresample",
 "swscale",
 "x264",
 "zlib"
 ]
 },
 "iniparser",
 "jsoncpp",
 "spdlog"
 ]
}




And I want to enable x11grab configuration in order to capture screen in Linux, but I found no feature was adapted.
Soon I found that —enable-libxcb was needed in configure and it was autodetect. So I build and install libxcb with source. And pkg-config can find it :


$ pkg-config --modversion xcb
1.17.0



But it doesn't work because in default it is —disable-autodetect in $VCPKG_ROOT/ports/ffmpeg/portfile.cmake :


set(OPTIONS "--enable-pic --disable-doc --enable-debug --enable-runtime-cpudetect --disable-autodetect")



I try to modify $VCPKG_ROOT/ports/ffmpeg/portfile.cmake —enalbe-autodetect, but it doesn't work either. Here is the short message when appling
vcpkg install --triplet x64-linux-release

How to combine 100 video clips with transition using FFMPEG ? [closed]
17 octobre 2024, par Muhammad Lutfi RahmawanI've been working on project which involves FFMPEG to process video. The goal is to produce a video from several clips and combine them with transition to each clips. We've succeeded to create video from 20 clips and 19 transitions are applied to merge each clips. But when it comes to a larger amount of clips, say 50, it becomes be failed.


The first thing we do is split the original video into several clips based on user selection and this command is successful (log splitting). Then we combine the clips with transition using below command.


Here is the sample command of FFMPEG which failed :


ffmpeg -y -i /tmp/0.mp4 -i /tmp/1.mp4 -i /tmp/2.mp4 -i /tmp/3.mp4 -i /tmp/4.mp4 -i /tmp/5.mp4 -i /tmp/6.mp4 -i /tmp/7.mp4 -i /tmp/8.mp4 -i /tmp/9.mp4 -i /tmp/10.mp4 -i /tmp/11.mp4 -i /tmp/12.mp4 -i /tmp/13.mp4 -i /tmp/14.mp4 -i /tmp/15.mp4 -i /tmp/16.mp4 -i /tmp/17.mp4 -i /tmp/18.mp4 -i /tmp/19.mp4 -i /tmp/20.mp4 -i /tmp/21.mp4 -i /tmp/22.mp4 -i /tmp/23.mp4 -i /tmp/24.mp4 -i /tmp/25.mp4 -i /tmp/26.mp4 -i /tmp/27.mp4 -i /tmp/28.mp4 -i /tmp/29.mp4 -i /tmp/30.mp4 -i /tmp/31.mp4 -i /tmp/32.mp4 -i /tmp/33.mp4 -i /tmp/34.mp4 -i /tmp/35.mp4 -i /tmp/36.mp4 -i /tmp/37.mp4 -i /tmp/38.mp4 -i /tmp/39.mp4 -i /tmp/40.mp4 -i /tmp/41.mp4 -i /tmp/42.mp4 -i /tmp/43.mp4 -i /tmp/44.mp4 -i /tmp/45.mp4 -i /tmp/46.mp4 -i /tmp/47.mp4 -i /tmp/48.mp4 -i /tmp/49.mp4 -filter_complex "[0:v][1:v]xfade=transition=circlecrop:duration=0.5:offset=24.474[tv0];[0:a][1:a]acrossfade=d=0.5[ta0];[tv0][2:v]xfade=transition=circlecrop:duration=0.5:offset=31.674[tv1];[ta0][2:a]acrossfade=d=0.5[ta1];[tv1][3:v]xfade=transition=circlecrop:duration=0.5:offset=37.234[tv2];[ta1][3:a]acrossfade=d=0.5[ta2];[tv2][4:v]xfade=transition=circlecrop:duration=0.5:offset=55.348[tv3];[ta2][4:a]acrossfade=d=0.5[ta3];[tv3][5:v]xfade=transition=circlecrop:duration=0.5:offset=76.07[tv4];[ta3][5:a]acrossfade=d=0.5[ta4];[tv4][6:v]xfade=transition=circlecrop:duration=0.5:offset=82.622[tv5];[ta4][6:a]acrossfade=d=0.5[ta5];[tv5][7:v]xfade=transition=circlecrop:duration=0.5:offset=103.122[tv6];[ta5][7:a]acrossfade=d=0.5[ta6];[tv6][8:v]xfade=transition=circlecrop:duration=0.5:offset=114.502[tv7];[ta6][8:a]acrossfade=d=0.5[ta7];[tv7][9:v]xfade=transition=circlecrop:duration=0.5:offset=122.258[tv8];[ta7][9:a]acrossfade=d=0.5[ta8];[tv8][10:v]xfade=transition=circlecrop:duration=0.5:offset=130.094[tv9];[ta8][10:a]acrossfade=d=0.5[ta9];[tv9][11:v]xfade=transition=circlecrop:duration=0.5:offset=134.33[tv10];[ta9][11:a]acrossfade=d=0.5[ta10];[tv10][12:v]xfade=transition=circlecrop:duration=0.5:offset=141.85[tv11];[ta10][12:a]acrossfade=d=0.5[ta11];[tv11][13:v]xfade=transition=circlecrop:duration=0.5:offset=145.59[tv12];[ta11][13:a]acrossfade=d=0.5[ta12];[tv12][14:v]xfade=transition=circlecrop:duration=0.5:offset=154.314[tv13];[ta12][14:a]acrossfade=d=0.5[ta13];[tv13][15:v]xfade=transition=circlecrop:duration=0.5:offset=155.998[tv14];[ta13][15:a]acrossfade=d=0.5[ta14];[tv14][16:v]xfade=transition=circlecrop:duration=0.5:offset=164.924[tv15];[ta14][16:a]acrossfade=d=0.5[ta15];[tv15][17:v]xfade=transition=circlecrop:duration=0.5:offset=168.184[tv16];[ta15][17:a]acrossfade=d=0.5[ta16];[tv16][18:v]xfade=transition=circlecrop:duration=0.5:offset=174.796[tv17];[ta16][18:a]acrossfade=d=0.5[ta17];[tv17][19:v]xfade=transition=circlecrop:duration=0.5:offset=186.724[tv18];[ta17][19:a]acrossfade=d=0.5[ta18];[tv18][20:v]xfade=transition=circlecrop:duration=0.5:offset=191.23[tv19];[ta18][20:a]acrossfade=d=0.5[ta19];[tv19][21:v]xfade=transition=circlecrop:duration=0.5:offset=195.778[tv20];[ta19][21:a]acrossfade=d=0.5[ta20];[tv20][22:v]xfade=transition=circlecrop:duration=0.5:offset=198.118[tv21];[ta20][22:a]acrossfade=d=0.5[ta21];[tv21][23:v]xfade=transition=circlecrop:duration=0.5:offset=201.506[tv22];[ta21][23:a]acrossfade=d=0.5[ta22];[tv22][24:v]xfade=transition=circlecrop:duration=0.5:offset=204.422[tv23];[ta22][24:a]acrossfade=d=0.5[ta23];[tv23][25:v]xfade=transition=circlecrop:duration=0.5:offset=210.243[tv24];[ta23][25:a]acrossfade=d=0.5[ta24];[tv24][26:v]xfade=transition=circlecrop:duration=0.5:offset=215.417[tv25];[ta24][26:a]acrossfade=d=0.5[ta25];[tv25][27:v]xfade=transition=circlecrop:duration=0.5:offset=219.057[tv26];[ta25][27:a]acrossfade=d=0.5[ta26];[tv26][28:v]xfade=transition=circlecrop:duration=0.5:offset=221.277[tv27];[ta26][28:a]acrossfade=d=0.5[ta27];[tv27][29:v]xfade=transition=circlecrop:duration=0.5:offset=224.875[tv28];[ta27][29:a]acrossfade=d=0.5[ta28];[tv28][ta28][30:v][30:a][31:v][31:a][32:v][32:a][33:v][33:a][34:v][34:a][35:v][35:a][36:v][36:a][37:v][37:a][38:v][38:a][39:v][39:a][40:v][40:a][41:v][41:a][42:v][42:a][43:v][43:a][44:v][44:a][45:v][45:a][46:v][46:a][47:v][47:a][48:v][48:a][49:v][49:a]concat=n=21:v=1:a=1[v][a]" -map "[v]" -map "[a]" /tmp/export-clip-94989d271066ace00459-9ba57089-d833-4cef-beb7-3c847e9958af.mp4

It stated that /tmp/0.mp4 has invalid data
moov atom not found


This only occurs when the number of clips > 20


Additional info :


- 

- I can run without any error in my local environment using Windows 11 (FFMPEG version N-114902-g277f051ff6-20240421)
- It fails on AWS Fargate environment using Ubuntu base image docker (FFMPEG version 7.1)






I hope I can get a solutive answer based on my case at least I get what is wrong with my approach
