Precise syncronized stream Recording
15 octobre 2020, par LuckyLuke1984I have multiple streams from cameras and I would like to capture an event from different point of views. My program opens at the moment X at once for each of these streams a different process that is calling an instance of ffmpeg to record the stream.
The problem is that the moment Y where the event happens is not exactly after Z seconds in each recorded file. There is a mismatch between each stream, resulting from different starting times of the videos.


How can I trigger the start of the recording more precisely ?

Redact parts of an audio file using python (FFMPEG)
18 août 2020, par K3rn3l5I have a use case where I need to dynamically redact parts of an audio file using python. For example sometimes I may have to remove between timestamps 10 to 15 and other times between 5 to 7, 12 to 16 and 21 to 26 . I have tried looking at FFMPEG and think it may be possible with filters or chaining filters, but I am having trouble figuring out which ones to use and the combination. Any help or pointers will be highly appreciated. TIA !
