Does VLC play M4F? Also trying to get a IPcam to work.

For questions and discussion that is NOT (I repeat NOT) specific to a certain Operating System.

Does VLC play M4F? Also trying to get a IPcam to work.

Postby r3volution11 » 11 Apr 2007 16:13

I am trying to play a video stream through the net for a Sony SNC-P1 using VLC (.8.6a) on Windows Vista.

From what I've discovered it looks like the Sony transmits the video in m4f format which is MPEG-4 in a nice candy shell (darn you Sony!).

When I try to load the stream VLC will download it but nothing will appear.

If you think it's required I can give a link to one of the cameras web URL's and the actual directory where the camera stores the streaming format locally. I'd rather not if possible due to bandwidth issues (DSL stinks, where's my Comcast cable?!).

Thanks!

Update:: I changed the camera to JPG mode and VLC now just gives me a black screen. What the dilly? :)

Is there any extra information that might help in helping figure out a solution to this problem?

I'm pretty good with tech stuff but this has me stumped. Codec's are a pain. :(

m4f file

Postby vikram » 16 Apr 2007 15:40

Hi
this is sony cam transmitted file.
Before transmit video it attach some it own heders. it is RIFF file. U can open this file in RIFF viewer. there you can see structure of file. this is some sort of GOP(group of pictures)
M4f file contains mpeg-4 or jpeg videos. find it then crop that video. then it will play(i think so...). but it is not just plane video file.
the user data starts after "00 00 01 B2" HEX code.

if u success to play let me know.
cheers
