Comment:

 To llarevo: thanks for testing, I believe I know what causes this bug and
 I have just posted a patch on ffmpeg-devel mailing list for discussion. As
 Carl suggested, please do not use "-t 300". Also using "-r 25" or not will
 not make any difference since you are capturing from a TV card using the
 PAL standard for which the framerate is fixed at 25fps and cannot be
 changed (you will only get a warning).
