ลองทำสคริปต์แปลงไฟล์ภาพเป็นวิดีโอ
วิธีใช้คือเข้าไปในไดเรคทอรี่ของไฟล์ภาพ แล้วสั่งรันโปรแกรมตรง ๆ
$ sudo aptitude install imagemagick mjpegtools
$ vi d.mkvid

mv $MAINFILE ..

popd

#rm -rf $WORKDIR

$ chmod 755 d.mkvid

ใช้งานได้แล้ว แต่ยังมีข้อเสียอยู่คือ แปลงเป็น avi โดยไม่จำเป็น
ขอศึกษาต่ออีกหน่อยครับ
ท่านใดพอมีความรู้ ช่วยแนะนำด้วยนะครับ :)
