12 mars 2010, parEn fonction de la configuration de la plateforme, l’utilisateur peu avoir à sa disposition deux méthodes différentes de demande de création de canal. La première est au moment de son inscription, la seconde, après son inscription en remplissant un formulaire de demande.

Seeking to Start Time in Piped FFMPEG Input
18 septembre 2020, par Trevor BallardI am trying to convert a series of videos into a livestream with FFMPEG. To do this, I have a program which copies video files to stdout and have configured ffmpeg to read from a pipe input.


The only issue is I cannot seek to a particular start time with
-ss
. I can specify duration with-t
, but the output will always begin at the start of the input stream. For example :

cat input.ts | \
ffmpeg -ss 00:01:15 \
 -t 30 \
 -i pipe: \
 -c:v copy \
 -c:a copy \
 output.ts



FFMPEG reports
pipe:: could not seek to position XXXX.XX
and begins from the start of the stream, but I am wondering if there is some other way to accomplish this without trimming the files before piping.

Get waveform data from audio file using FFMPEG
16 septembre 2020, par LutandoI am writing an application that needs to get the raw waveform data of an audio file so I can render it in an application (C#/.NET). I am using ffmpeg to offload this task but it looks like ffmpeg can only output the waveform data as a png or as a stream to gnuplot.



I have looked at other libraries to do this (NAudio/CSCore) however they require windows/microsoft media foundation and since this app is going to be deployed to azure as a web app I can not use them.



My strategy was to just read the waveform data from the png itself but this seems hacky and over the top. The ideal output would be a fix sampled series of peaks in an array where each value in the array is the peak value (ranging from 1-100 or something, like this for example).
