Dat is de nagel aan de doodskist van elke bereidwillige forumhelper. Het ontgaat me nog steeds hoe mensen denken geholpen te kunnen worden door uitlatingen als 'het werkt niet' ... en dan verwachten dat iemand helderziende is om te weten hoe dat komt.
Maar ...
Je screenshot brengt me wel naar de kern van het probleem denk ik : ik zie nl dat het om een M4V bestand gaat !!!
En :
"The M4V file format is a video container format developed by Apple and is very similar to the MP4 format. The primary difference is that M4V files may optionally be protected by DRM copy protection. Apple uses M4V to encode video files in its iTunes Store. Unauthorized reproduction of M4V files may be prevented using Apple's FairPlay copy protection. A FairPlay-protected M4V file
can only be played on a computer authorized (
using iTunes) with the account that was used to purchase the video.
The format
without DRM can also be played in the webOS Video Player for use on the Palm Pre, Palm Pixi smartphones. It is also playable by the Android operating system with its video player. It is used as the default video conversion format for HandBrake and Air Video Server on the Macintosh.
Some other video players can also recognize and play M4V files if the file extension is changed from ".m4v" to ".mp4"...
Zou dat je probleem kunnen zijn ?
indien Eng probleem - gooi het dan even in Google Translate !
