Limit the cpu usage when converting youtube videos to mp3 using youtube-dl
30 novembre 2015, par KamalI am using youtube-dl & avconv with php on nginx server to convert youtube video into mp3. Using htop I noticed the usage of cpus peak at 100% when couple of avconv processes are running at the same time, and once my server crushed down because of that.
The first solution that I encountered cpulimit but after some research,I’ve found cpu limit is not smart enough to handle multiple simultaneous instances.
From this answer I learned that I can limit the number of cpu threads using
-threads
option.
My basic command :youtube-dl --extract-audio --audio-format mp3 <video url="url"></video>
I wonder if I can add -threads option to the youtube-dl command, I am not sure if that is possible.
I have 2 cores cpu server, I am thinking of upgrading to 4 cores cpu and limit the avconv to use just 2 cores, what do you think ? Is that the best way to go (using thread option) ?

avcodec/ppc/h264dsp : POWER LE support in h264_idct_dc_add_internal() fix vec_lvsl bug
14 mai 2015, par Rong Yanavcodec/ppc/h264dsp : POWER LE support in h264_idct_dc_add_internal() fix vec_lvsl bug
We got defective video when use GCC 4.9.2 instead of GCC 4.9.1 to compile FFMEPG. And further found
that GCC 4.8 and 4.9 need patch to fix the lvsl/lvsr bug on POWER LE, and GCC 5.1 contains
the correct code since its release. The message on gcc-patches requesting approval for lvsl/lvsr
patch is at https://gcc.gnu.org/ml/gcc-patches/2014-10/msg00228.html.The fixed code avoids using lvsl and will not depends on GCC version, also it uses less instructions on POWER LE.
