[Ffmpeg-devel] Video compression and quality of codecs.
Wed Apr 5 12:44:42 CEST 2006
I have tested the H263 codec in order to achieve best compression and
quality (an utopia, I know).
After playing around with bitrates, resolutions and framerates I
obtained something like:
Framerate: 10 fps
Keyframe: 1/s (one keyframe at a second)
(KiloBytes per second)
The problem was that I was getting some small (and sometimes bigger)
squares (done probably by the super-sampling).
Now, someone showed me a live streaming at the same resolution , at 15
fps using a WMV proprietary codec and RTSP streaming and obtained the
Framerate: 15 fps
KB/s 15 (!!)
What astonishes me is the quality which was so much better on the WMV
codec and only the buffering times were way to big (~2-3 seconds at
encoding and decoding, resulting a cumulative delay of ~4-6 seconds).
That means there is room for improvement.
Anyway, regarding strictly compression, the question that wonders me is:
which is the best codec that still keeps a good quality in FFmpeg not
regarding CPU consumption, memory or other factors, simply compression?
Have a nice day anyone,
