Re: [mythtv-users] CPU for spftware MPEG-4 encoding
*grrr for top posting* The PVR250/350 is MPEG2, not MPEG4 as the poster asked. I transcode from an MPEG2 PVR250 stream at 4mbit/sec, 720x576 to MPEG4 1000kbit/sec 360x288 on my system, and it seems to do about 20 frames per second. This is a P4-2GHz. Playback of the resulting file uses around 20-30% So it is my experience that transcoding is not realtime on my PC, but playback is. Recording from raw frames to MPEG4 might be easier on the PC than transcoding. HTH Mark On Wed, 2005-04-06 at 15:34 +0200, Morten Rønseth wrote: But a PVR-350 both encodes decodes in hardware...
