Other interesting software
13 avril 2011, parWe don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
We don’t know them, we didn’t try them, but you can take a peek.

FFmpeg Centos Compile Error - caused by libwebp (error : implicit declaration of function ‘libwebp_error_to_averror’)
2 septembre 2022, par fvid1I'm trying to compile FFmpeg on Centos 7.9. I followed the official instructions : https://trac.ffmpeg.org/wiki/CompilationGuide/Centos


I need support for WebP images, so I installed
libwebp
andlibwebp-devel
via YUM, and used the option--enable-libwebp
.

But at the ffmepg "make" stage, the following error is returned :


CC libavcodec/libwebpenc_common.o
libavcodec/libwebpenc_common.c: In function ‘ff_libwebp_get_frame’:
libavcodec/libwebpenc_common.c:283:17: error: implicit declaration of function ‘libwebp_error_to_averror’ [-Werror=implicit-function-declaration]
 ret = libwebp_error_to_averror(pic->error_code);
 ^
cc1: some warnings being treated as errors
make: *** [libavcodec/libwebpenc_common.o] Error 1



Does anyone know why this error is occuring and how it can be corrected ?


I've tried compiling without using
--enable-libwebp
and it works fine.

Stream to youtube using Hardware Encoding
28 août 2021, par Renan F.I'm currently streaming to youtube using NVIDIA hardware encoding to reduce the load on the CPU, with this code :


ffmpeg -framerate 30 -f gdigrab -i desktop -f lavfi -i anullsrc -c:v h264_nvenc -f flv "rtmp://a.rtmp.youtube.com/live2/KEY"



My screen resolution is 2560x1080, but this is the result i get in youtube :



There are huge empty spaces on both sides, and the resolution is not so good, even selecting "HD" on youtube.


I tried to specify in the last parameter before
flv
,
-s 2560x1080
but I could not see any difference.

Also would like to ask if someone knows what
-qp 0
does, I could not find it in the documentation, it does appear here :

https://trac.ffmpeg.org/wiki/Capture/Desktop


Under hardware encoding.


Looking for any advice, taking in mind I'm trying to reduce the CPU usage and keep a normal/good resolution.
