Transcode H.264 material
Hi,
my serviio system runs on a DualCore with 2,8Ghz and a Geforce 9400GT.
I have problems when transcoding h.264 to my grundig tv.
The movie can be played, but after a short time it began to stutter.
Here is my ffmpeg configuration:
ffmpeg version 1.2 Copyright (c) 2000-2013 the FFmpeg developers
built on Apr 30 2013 10:58:48 with gcc 4.4.7 (GCC) 20120313 (Red Hat 4.4.7-3)

libavutil 52. 18.100 / 52. 18.100
libavcodec 54. 92.100 / 54. 92.100

libavfilter 3. 42.103 / 3. 42.103

libswresample 0. 17.102 / 0. 17.102
libpostproc 52. 2.100 / 52. 2.100
Iam not sure about gpu hardware acceleration. Can it be used for decoding? FFMpeg is compiled with vdpau support.
Or is it only useful when directly playing the movie on the server?
Here is the problematik file:
