avutil : Fix linking x86 asm constants with Clang in MSVC mode
12 juin, par Martin Storsjöavutil : Fix linking x86 asm constants with Clang in MSVC mode
This fixes building with Clang in MSVC mode, for x86, which was
broken in 6e49b8699657b808b7dc80033f2c3f2d0e029fa3 (in Nov 2024) ;
previously it failed with undefined symbols for the constants
defined with DECLARE_ASM_CONST, accessed via inline assembly.Before 57861911a34e1c33796be97f2b2f44e05fffd647, there was an
#elif defined(__GNUC__) || defined(__clang__)
case before the
#elif defined(_MSC_VER)
case for defining DECLARE_ASM_CONST, which included av_used.
(This case included the explicit "defined(__clang__)" since
f637046d3134a331e4b5a7243ac3dfb92735b8a5.)After 57861911a34e1c33796be97f2b2f44e05fffd647, it used the
generic definition of DECLARE_ASM_CONST that also included
av_used - which also worked for Clang in MSVC mode. But after
6e49b8699657b808b7dc80033f2c3f2d0e029fa3, Clang in MSVC mode
ended up using the MSVC specific variant which lacked the
av_used declaration, causing linker errors due to undefined
symbols.Signed-off-by : Martin Storsjö <martin@martin.st>

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

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
