Script d’installation automatique de MediaSPIP
25 avril 2011, parAfin de palier aux difficultés d’installation dues principalement aux dépendances logicielles coté serveur, un script d’installation "tout en un" en bash a été créé afin de faciliter cette étape sur un serveur doté d’une distribution Linux compatible.
Vous devez bénéficier d’un accès SSH à votre serveur et d’un compte "root" afin de l’utiliser, ce qui permettra d’installer les dépendances. Contactez votre hébergeur si vous ne disposez pas de cela.

The final lib was created successfully, no error message in log file,
but when I import the lib to my Xcode Project,
the linker give me tons of errors(missing symbols like :
Undefined symbol: _pjsua_vid_codec_set_priority).
I found thepjsua_vid.ois very small(200Bytes) compare to my pjsip+openh264 build file(was 47KB), perhaps this is the reason cause the link error.

Here is my build log :

ffmpeg headphone convolution audio filter with non standard channel layouts
4 février 2021, par dts350zI am successfully using ffmpeg's headphone convolution audio filter (see ffmpeg filters documentation section 8.78) to make binaural versions of surround sound with up to 16 channels. As long as the channel layouts are recognized by ffmpeg.


I have 32 IRs (16 stereo pairs) in one file and can use it for :


Stereo
5.1,
7.1,
and
7.1.4.4 (16 channels).


The order of the pairs in the IR file is :


FL|FR|FC|LFE|BL|BR|SL|SR|FLC|FRC|TFL|TFR|BC|TC|TBL|TBR


So all of those formats are subsets of the IR file, and in order.


Surround input files, with more than 8 channels, have channels assigned in their headers by previously applied ffmpeg commands.


Such as :


ffmpeg.exe" -y -i %%x -acodec pcm_s24le -af "pan=7.1+TFL+TFR+TBL+TBR|FL=c0|FR=c1|FC=c2|LFE=c3|SL=c6|SR=c7|BL=c4|BR=c5|TFL=c8|TFR=c9|TBL=c10|TBR=c11" "%%~nx_12ch_mapped.wav"


for 12 channels and :


ffmpeg.exe" -y -i %%x -acodec pcm_s24le -filter_complex "pan=FL+FR+FC+LFE+BL+BR+SL+SR+FLC+FRC+TFL+TFR+BC+TC+TBL+TBR|FL=c0|FR=c1|FC=c2|LFE=c3|BL=c4|BR=c5|SL=c6|SR=c7|FLC=c8|FRC=c9|TFL=c10|TFR=c11|BC=c12|TC=c13|TBL=c14|TBR=c15" "%%~nx_16ch_mapped.wav"


for 16 channels.


So here is a working convolution command. Again it works for stereo, 5.1, 7.1 and 16 channel surround input files (only the gain needs changing for the different channel count inputs) :


ffmpeg.exe" -hide_banner -y -i "%%~nx_48KHz.wav" -i "%parent%\My-IR.wav" -filter_complex "[1:0]pan=stereo|c0=c0|c1=c1[fl];[1:0]pan=stereo|c0=c2|c1=c3[fr];[1:0]pan=stereo|c0=c4|c1=c5[fc];[1:0]pan=stereo|c0=c6|c1=c7[lfe];[1:0]pan=stereo|c0=c8|c1=c9[bl];[1:0]pan=stereo|c0=c10|c1=c11[br];[1:0]pan=stereo|c0=c12|c1=c13[sl];[1:0]pan=stereo|c0=c14|c1=c15[sr];[1:0]pan=stereo|c0=c16|c1=c17[flc];[1:0]pan=stereo|c0=c18|c1=c19[frc];[1:0]pan=stereo|c0=c20|c1=c21[tfl];[1:0]pan=stereo|c0=c22|c1=c23[tfr];[1:0]pan=stereo|c0=c24|c1=c25[bc];[1:0]pan=stereo|c0=c26|c1=c27[tc];[1:0]pan=stereo|c0=c28|c1=c29[tbl];[1:0]pan=stereo|c0=c30|c1=c31[tbr];[0:a][fl][fr][fc][lfe][bl][br][sl][sr][flc][frc][tfl][tfr][bc][tc][tbl][tbr]headphone=gain=32:map=FL|FR|FC|LFE|BL|BR|SL|SR|FLC|FRC|TFL|TFR|BC|TC|TBL|TBR[fh]" -map [fh]:a "%%~nx_h_binaural.flac"


Which gives results :

However for channel layouts that need to skip some of the IRs, such as 4.0, 5.0, and 7.1.4 (12 channels) I can't figure out how to make it work. In the 12 channel case, I even cut the IR file down to 24 channels (12 pairs) and tried this :


ffmpeg.exe" -hide_banner -y -i "%%~nx_48KHz.wav" -i "%parent%\IR-Files\A16_12ch_IR 12_Pairs_A16_Order.wav" -filter_complex "[1:0]pan=stereo|c0=c0|c1=c1[fl];[1:0]pan=stereo|c0=c2|c1=c3[fr];[1:0]pan=stereo|c0=c4|c1=c5[fc];[1:0]pan=stereo|c0=c6|c1=c7[lfe];[1:0]pan=stereo|c0=c8|c1=c9[bl];[1:0]pan=stereo|c0=c10|c1=c11[br];[1:0]pan=stereo|c0=c12|c1=c13[sl];[1:0]pan=stereo|c0=c14|c1=c15[sr];[1:0]pan=stereo|c0=c16|c1=c17[tfl];[1:0]pan=stereo|c0=c18|c1=c19[tfr];[1:0]pan=stereo|c0=c20|c1=c21[tbl];[1:0]pan=stereo|c0=c22|c1=c23[tbr];[0:a][fl][fr][fc][lfe][bl][br][sl][sr][tfl][tfr][tbl][tbr]headphone=gain=10:map=FL|FR|FC|LFE|BL|BR|SL|SR|TFL|TFR|TBL|TBR[fh]" -map [fh]:a "%%~nx_h_binaural.flac"


But it gives the following output :

and I can't figure out where to put the suggested aformat=channel_layouts=something.


Suggestions ?

format dav not convert [closed]
5 décembre 2020, par Raphael FigueiredoI have this file that comes from of an unknown brand, however when I use the code that I am used to normally use in other models it does not work, appears format dav detected only with low score of 1 misdetection possible.
I use the following code :


forfiles / s / M * .dav / C "cmd / c ffmpeg -i @file -vf setpts = 2.0 * PTS @ fname.avi -n"
