Ok, let see, I have finally made it work. However, I have another drawback. Since I am using the audio stream to be multiplexed with video with ffmpeg, I have noticed that when sending audio, ffmpeg works at a normal codifying rate. However, when having silence, it works at a slower rate, and then, the final result is a bit unpleasant, since the final video image goes "by jumps" - this is, the codifier just codify each 2 seconds or so, so the image just changes after 2 secs -. I don't know if it has to do with pulseaudio or ffmpeg, I have started looking in ffmpeg, but if u know there's a problem in pulseaudio, please let me know!!! Regards.
