For those interested in which codecs we have used and which resolutions,
here's a list collected from all the TASvideos movies currently available
to
in the MKV, MP4, or AVI header.
| Count | Rate | Channels |
| 764 | 44100 | stereo |
| 564 | 48000 | mono |
| 366 | 44100 | mono |
| 332 | 48000 | stereo |
| 21 | 32000 | stereo |
| 15 | 22050 | stereo |
| 10 | 24000 | stereo |
| 5 | 22050 | mono |
| 4 | 24000 | mono |
| 2 | 32000 | mono |
| 1 | 16000 | stereo |
| 1 | 43931 | stereo |
| 1 | 96000 | mono |
| 1 | 32006 | stereo |
| 1 | 44095 | stereo |
Total: 2088 encodes (total length 929 hours 31 minutes 7.79 seconds)
- Note that most movies having ”DIVX” in their header are actually encoded using the ”FMP4” codec (the ffmpeg variety of MPEG-4 video. For Windows users, it is provided by ffdshow). ”DIVX” fourcc is only used for compatibility.
- Sometimes the ”XVID” fourcc is used for the same purpose, though most of the ”XVID” movies are truly indeed XVid.
- "VP80" fourcc is the VP8 codec.

sgrunt used the following to generate this list (requires
mplayer):
(
for all in *.avi *.mkv *.mp4 *.ogm; do
mplayer -identify -frames 0 $all >mpout
fmt=`grep ID_VIDEO_FORMAT mpout | sed 's@.*=@@'`
width=`grep ID_VIDEO_WIDTH mpout | sed 's@.*=@@'`
height=`grep ID_VIDEO_HEIGHT mpout | sed 's@.*=@@'`
echo $fmt, ${width}x$height
done
)|sort|uniq -c|sort -rn
When this list was maintained by
Bisqwit, he used the following
to create the listing (requires
riffdump and mkvtoolnix):
(
for s in *.avi;do riffdump -nmovi "$s";done | \
grep -a strf.*bits| grep -av 4[48][01]00x | \
sed 's/.*bytes[^(]*(//;s/(.*, /, /;s/(.*//'
for s in *.mkv;do mkvinfo --summary "$s" |head -n 2|grep 'video, codec';done | \
perl -pe 's/.*ID: (.*), def.*pixel width: (.*?), pixel height: (.*?),.*/\1, \2x\3/' | \
perl -pe 's@V_MS/VFW/FOURCC \(FourCC: (.*?), 0x34363268\)@\1@'
) | sort|uniq -c|sort -rn
