Hi, all, I am doing a project to port the gstreamer framework to a target board, which is running linux 2.6.24 on ARM 9, and the RAM on the board is 32Mbyte. When I tried to use the gstmad and alsalink plugin to play a MP3 file ( "gst-launch location = abc.mp3 ! mad ! alsasink"), I found there is constant audio underrrun reported from the ALSA driver and thus there are on/off in the audio output. I've also tried other MP3 demux/decoders such as ffdemux_mp3 and ffdec_mp3 but the result is same. After I enabled the debugging on the filesrc plugin, I noticed there is a break/pause sometimes (happening randomly) during the playback. I suspect this could be the reason of the audio underrun but I don't know why this break/pause happens. Anyone has any idea? Please help. regards, Jianfeng -------------- next part -------------- An HTML attachment was scrubbed...
