Um Screencasts unter Haiku zu machen muss man derzeit noch auf die alte BeOS Screencast Software BeScreenCapture zurückgreifen. Ich habe mal aus Neugierde ein Bash-Script geschrieben das ebenfalls im Zusammenspiel mit FFMPEG und dem Screenshot Tool unter Haiku im Stande ist Screencasts zu machen.
Noch nicht berücksichtigt ist hier natürlich Audio. Auch die Bilder pro Sekunde sind noch zu wenig um eine 1:1 Geschwindigkeit darstellen zu können. Alles in allem ist es aber recht brauchbar, wenn man etwas mal schnell zeigen möchte.
Wenn jmd. interesse hat, dass Tool auszubauen oder auf Basis des Scripts eine GUI zu basteln wäre das sehr schön. Aus diesem Grund stelle ich das Script hier auch online :)
Zur Benutzung muss (wie im folgenden Video auch zu sehen) das Script im Terminal gestartet werden. Dazu kann man die Datei direkt ausführbar machen oder ber sh screencast aufrufen.
Achten muss man darauf, das alte Screenshots(mit dem namen screenshot1 usw.) gelöscht werden sollten, da diese sonst mit in das Video eingearbeitet werden. Nach Erstellung des Videos das im /boot/home Ordner unter dem Namen out.mp4 abgelegt wird, werden sämtliche png Dateien im Home Ordner gelöscht.
Die benötigte ffmpeg Abhängigkeit findet ihr hier: http://ports.haiku-files.org/wiki/Downloads
Hier ein Beispielvideo, dass ein weiteres kleines Programm (geschrieben in YAB) demonstriert.
Noch ein kleiner Tipp: Für das erstellen des Screencast keine allzu hektischen Bewegungen aufnehmen. Und vielleicht etwas langsamer arbeiten als man es evtl. gewohnt ist. Damit gelingen bessere Screencasts. Das vertonen der Screencasts kann später auch übernommen werden. Hier sollte man darauf achten das man sich im Zeitrahmen des Videos bewegt. Am besten also bei der Aufnahme des Audios das Video abspielen um so eine mögliche Synchronisation zu bekommen. Später kann die Audiospur mit Hilfe von FFMPEG folgender maßen mit dem Video verschmolzen werden:
ffmpeg -i video.mp4 -i sound.mp3 -sameq videomitsound.mp4
Viel Spaß beim experimentieren mit Screencasts unter Haiku :)

It happens to bе a chef's term for 'a position

Sitting there on your counter, it hardly looks capable of these kinds of wonders, but the primary timers and the seasoned cooks alike will like incorporating that customary taste to their most loved dishes.

Too cool!

A fascinating discussion is definitely worth comment.
I do believe that you should publish more on this subject matter, it may not be a taboo subject
but typically people do not talk about such topics. To the next!
