XVID example - start guide

[radone]

For anyone who is staring with X-VID source code - here is some hints that could make it easier to start:

(Compiling of source codes is out of scope here)

At first dowload any video file (they are very often read from some device in so called YUV420 format) http://www.tkn.tu-berlin.de/research/evalvid/cif.html

They are all in CIF format: 352x288 pixels.
uzip downloaded file
bunzip filename.bz2

How to encode it:
./xvid_encraw -type 0 -w 352 -h 288 -i yuv_multiple.yuv -o out.mp4

how to decode it:
./xvid_decraw -i out.mp4 -f pnm -d

At first download any video file Per forum rule 6, we do not discuss downloaded files. Please don't do it again.

Per forum rule 6, we do not discuss downloaded files. Please don't do it again.

Huh? Rule 6 doesn't apply at all here. These are freely available video test sequences that have been used for research and testing for years. They're also hosted on xiph: http://media.xiph.org/video/derf/ along with the freely available vqeg test sequences: http://media.xiph.org/vqeg/TestSeqences/ and the University of Munich's: http://www.ldv.ei.tum.de/liquid.php?page=70

All of which are referenced often in these forums.

Said any video, not any of these videos. Still yeah, I wouldn't say rule 6. Post does seem rather pointless though.

I didn't follow the link. I just have radar for references to downloaded files.

Radone's post provides specific help on how to encode and decode the samples hosted at http://www.tkn.tu-berlin.de/research/evalvid/cif.html to/from XviD via CLI. Though the post seems somewhat unmotivated I see no harm in it. :)

Suggestion: don't use .mp4 as the filename extension. People might be misled.
