Re: Video streaming module

I found ffmpeg quite good for producing/capturing video streams. Depending on the Wifi camera, it most likely produces an RTSP stream, and ffmpeg can record these to disk (for later viewing or re-encoding):

ffmpeg -i rtsp://@192.168.241.1:62159 -r 15 C:/DB_Videos/2013-04-30 17
+_18_34.703.mp4
[download]

ffmpeg -i rtsp://@192.168.241.1:62156 -acodec copy -vcodec copy c:/abc
+.mp4
[download]

I haven't found any good abstraction for ffmpeg on CPAN yet, and my attempts haven't crystallized into anything worthwhile yet either.

Not really an abstraction for ffmpeg, but a bit of PDL that can interface with it: PDL::IO::Pic. I can envision (ha!) additional functionality for the `rmpeg` function that could interface to a stream (obviously relying largely on ffmpeg capability). Today, that's a synchronous read rather than a stream. What do people think would some sample (maybe pseudo-)code look like that would solve this? I anticipate a write-stream as well, but don't want to bias people's thinking.	[reply] [d/l]

I wrote VideoLAN::LibVLC which could do the job but the portions I implemented are more focused on playback. An API for ffmpeg would most likely be named "libav".	[reply]
