How do you play 3gp video files?

[WPWoodJr]

I copied some .3gp videos from my phone to the Subsonic server and added a 3gp > flv transcoding and enabled that transcoding for my Android player. It didn't help. My player still can't see the .3gp files.

Help!

Hmmm... this is not intuitive but I renamed my .3gp videos to .mp4 and now Subsonic can play them.

OK, so I found under Settings...General where you set the video and the audio file extensions. So, I can add .3gp as a video file type and then add a transcoding command for it.

Also make sure you enable the new type in the players too.

Yes, I realized I need to do that. However, it isn't working. It works fine when I rename the .3gp files to .mp4, but not when I try to do it "right".

Maybe ffmpeg doesn't recognize the file properly when its extension is .3gp?

Here's what it says in the log:

Code: Select all

[2/14/11 10:19:24 PM EST]   DEBUG   InputStreamReaderThread   (c:\subsonic\transcode\ffmpeg) Invalid duration specification for ss: %o

The duration isn't being interpreted properly for some reason.

So I took off the -ss %o command from the ffmpeg transcoding command line and still got an error "Incorrect frame size":

Subsonic seems to be able to read .mp4 files to find out the values of parameters to pass to ffmpeg such as the frame size. It is not able to do this for .3gp files even though they are a form of mp4 format. That's why I'm getting the frame size and other errors.
