Choppy audio/video while transcoding
Posted: 31 Mar 2010 11:16
Hi!
I`m transcoding from a RTSP source (QVidium hardware encoder) to http (in flv format using x264 codec). rtsp caching is set to 5000, sout caching is set to 12 000 ( --rtp-caching=5000 --sout-mux-caching=12000). After a day or two, audio/video begin choppy and vlc show this:
Is there any possibility to get rid out of this?
I`m sure, CPU is capable to transcode video in x264 in realtime, so this is not the root of the problem
