I am using Darwin Streaming Server (DSS) to stream mpeg4 encoded videofiles.
I create my streamable content with an automated process using ffmpeg for video (mpeg4) and audio (AAC) encoding, and gpac MP4Box for hinting.
Everything resides on a Slackware Linux computer. And Darwin is version 5.5.4.
It works great to stream individual files.
But when I place some of these files in a playlist on DSS. The playlist runs fine for a couple of hours. Then the audio gets cut off when accessing the playlist. The video keeps running. If I stop the stream and play it again. The audio works.
I also have a 3gp playlist, which streams 3gp content. And for this playlist it is the opposite. The video halts, and the audio continues. The 3gp content is also created with ffmpeg (mpeg4/AMR NB).
I have studied the streams with QT Pro, and when this happens. The buffer graph in the statistics goes haywire. So I strongly suspect this is some kind of bufferingproblem.
Also when I stop the malfunctioning playlists in DSS, and then start them again. The problem is gone, for about a couple of hours again.
Has anyone got some ideas what may be causing this?
