Compilation error when compiling libvpx for FFMPEG
29 septembre 2014, par Flock DawsonI’m compiling FFMPEG on my 64bit Ubuntu 14 machine. Everything compiled well, except for the libvpx library, which keeps throwing errors :
[AS] vp9/common/x86/vp9_subpixel_8t_ssse3.asm.o
vp9/common/x86/vp9_subpixel_8t_ssse3.asm:856: warning: label alone on a line without a colon might be in error

vp9/common/x86/vp9_subpixel_8t_ssse3.asm:1002: error: invalid combination of opcode and operands
make[1]: *** [vp9/common/x86/vp9_subpixel_8t_ssse3.asm.o] Error 1
make: *** [.DEFAULT] Error 2I followed this guide : https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu
I don’t know what this error means, but read somewhere that compiling libvpx with NASM is broken, but I don’t know how to compile it otherwise. Installing version 1.2 or 1.1 makes no difference whatsoever. Any ideas ? -
Video Filters like Instagram and save in SDCARD
7 mai 2018, par Harsh BhavsarColor Channel Mixer (Info.)
https://ffmpeg.org/ffmpeg-filters.html#colorchannelmixerI am trying to creating video filters using FFMpeg and OpenCV just like Instagram Video filters.
So if I want to create Sepia Effect Then I have to use color channel mixer for that with RGBA values
ex. colorchannelmixer=.393 :.769 :.189:0 :.349 :.686 :.168:0 :.272 :.534 :.131 (This code for Sepia Effect)
Now I want to create more effects like Instagram. So need different color channel mixers for that
How to create them ?Ref. — https://github.com/krazykira/VidEffects/wiki/Permanent-video-effects
I got only 2 filters
Sepia
colorchannelmixer=.393 :.769 :.189:0 :.349 :.686 :.168:0 :.272 :.534 :.131Grayscale
colorchannelmixer=.3 :.4 :.3:0 :.3 :.4 :.3:0 :.3 :.4 :.3I need more filters.
private void initVideoRecorder(String path) {
try {
filter = new F FmpegFrameFilter("colorchannelmixer=.393:.769:.189:0:.349:.686:.168:0:.272:.534:.131", VIDEO_GRABBER.getImageWidth(), VIDEO_GRABBER.getImageHeight());
videoRecorder = FFmpegFrameRecorder.createDefault(path, VIDEO_GRABBER.getImageWidth(), VIDEO_GRABBER.getImageHeight()); videoRecorder.start();
}
catch (FrameRecorder.Exception e) {
e.printStackTrace();
}

I only have two presets for ffmpeg x264 in ubuntu 11.04
17 octobre 2012, par Mr X ColombiaI'me trying to install (compile) ffmpeg for ubuntu 11.04 by following this guide :
https://ffmpeg.org/trac/ffmpeg/wiki/UbuntuCompilationGuide
Overall it works. Except for some errors with checkinstall due to numbering, which i resolved with this :
I'd say it was installed ok.
But when trying to encode some video with -vpre lossless_slow i get this error :
File for preset lossless_slow not found.
And in fact it doesn't exists. All i have is this :
/usr/local/share/ffmpeg:
libvpx-1080p50_60.ffpreset
libvpx-1080p.ffpreset
libvpx-360p.ffpreset
libvpx-720p50_60.ffpreset
libvpx-720p.ffpreset
libx264-ipod320.ffpreset
libx264-ipod640.ffpresetWhere are all the other presets ? in google usually people have many more presets than i do. What did i do wrong ?
From this post i'd say that they shopuld be there : http://git.videolan.org/?p=ffmpeg.git ;a=commit ;h=4b82e3cedcfc9871671bb613cd979de6995dcb4e
Thanks a lot !
