Hi
We are investigating the possibility of using ffmpeg to record and
playback video
Could anyone tell me if it is possible to play back and seek within a
file that is recording
at the same time.
So
If we have a program that starts capturing video from an external
source, encodes and records to disk
and at the same time, play the video to screen and (most importantly)
seek within it.
(jog/shuttle/ffw etc).
Is this possible?
Any caveats?
I did something similar a few days ago. I used the Live555 library to
dump an mpegts stream into a local temp file from an RTSP server. Then I
used libav to play that file at the same time on different threads and
everything worked fine. I guess you just have to be sure of not crossing
the boundaries of the temporary file.
