[Libav-user] General concat input to stream output questions

[Deron]

Hello,

I've been a user of ffmpeg for many years, but always managed until now 
to do what I need without diving into libav.

I would like to stream multiple media files (never ending list) to an 
mpegts. Concat doesn't work because (I presume) non-incrementing PTS, so 
I would like to try my hand at an endless video stream and I'd like a 
little guidance or maybe someone has seen something similar done and can 
point me to the project?

Looking at the transcoding example, I'm going to guess I can create the 
output context and then for each input create a context and decode it 
into the filtergraph. With each new video, I presume I would need to 
make some kind of changes to the filtergraph? How much needs to be 
rebuilt, and how much can just be repurposed?

Is there any kind of examples which breaks down ffmpeg parameters to 
libav calls?

As a side note, is there some way to search the archives of this list? 
Seems like a lot of knowledge buried in plain sight.

Thanks in advance for any help,

Deron
