Here is my benchmark results for MPEG2 decoders and deinterlacers, avaliable in GStreamer.
GStreamer compiled from sources, the versions of the software are:
gstreamer-0.10.36
gst-plugins-base-0.10.36
gst-plugins-good-0.10.31
gst-plugins-bad-0.10.23
gst-plugins-ugly-0.10.19
gst-ffmpeg-0.10.13
Orc acceleration is enabled, the testing CPU is AMD Athlon(tm) 64 X2 Dual Core Processor 4200+ (2,2Ghz). The input image dimensions are 720x576.
| MPEG2 Decoder | Resolution | CPU Usage |
|---|---|---|
| ffdec_mpeg2video | halfres | 7...8 % |
| ffdec_mpeg2video | fullres | 10...11 % |
| mpeg2dec | fullres | 15...17 % |
| Deinterlacer | Mode | CPU Usage |
|---|---|---|
| ffdeinterlace | none | 3...5 % |
| deinterlace | 0-tomsmocomp | 32...34 % |
| deinterlace | 1-greedyh | 30...32 % |
| deinterlace | 2-greedyl | 8...9 % |
| deinterlace | 3-vfir | 8...9 % |
| deinterlace | 4-linear | 7...8 % |
| deinterlace | 5-linearblend | 8...10 % |
| deinterlace | 6-scalerbob | 7...8 % |
| deinterlace | 7-weave | 7...8 % |
| deinterlace | 8-weavetff | 6...8 % |
| deinterlace | 9-weavebff | 7...9 % |
| Scaler | Mode | CPU Usage |
|---|---|---|
| videoscale | 0-nearest-neighbour | 1...2 % |
| videoscale | 1-bilinear | 5...6 % |
| videoscale | 2-4-tap | 10...11% |
TODO: benchmark for ffvideoscale (it must be faster than gstreamer's scaler).
