Deploying ffmpeg from Windows Machine using Cpanel
24 février 2017, par BBobA site developed on a Windows machine using WAMP employs ffmpeg.exe to convert videos. The site will be deployed on a server running Linux. All of the links I have seen seem to require ffmpeg to be compiled and linked on the host machine. How can ffmpeg be deployed from Windows system to a Linux site thru CPanel ?

The
[Parsed_subtitles_0 @ 0x6000229c0] Neither PlayResX nor PlayResY defined. Assuming 384x288
warning is not a part of the problem, as converting the subtitles to.ass
viaffmpeg -i file.srt file.ass
and specifying the PlayResX and Y values makes the warning disappear without solving the original issue.I know that the libass library, which provides the subtitles filter to ffmpeg, uses fontconfig, which is known not to work out-of-box under windows. However, the lack of any fontconfig warnings makes me believe that this is not the problem here. Any leads as to what might the cause of the problem be ?
EDIT : I have downloaded and compiled ffmpeg myself :
$ git clone git://source.ffmpeg.org/ffmpeg.git ffmpeg
$ cd ffmpeg
$ ./configure --enable-static --disable-shared --enable-libass
$ makeThe output of the conversion
./ffmpeg -i file.mp4 -vf subtitles=file.srt file.ts
is identical except for the fact that no warning messages get printed this time around. I’m looking into whether the fontconfig library configuration could be the culprit.
