HELP: ffmux_mov question

[Song, Yingsheng]

Hi Nicola, thanks a lot for your valuable information. I had a quick look at the mp4mux and am very interested in it. However we are still using an old gstreamer release (LINUX) without mp4mux element. As there are modifications on some gstreamer elements, it looks like upgrade to new gstreamer release is not an option at this time.
Do you know if the mp4mux rpm has to work with certain gstreamer releases or it may be workable with old gstreamer release, such as 0.10.25?

I saw the faststart property, but don’t fully understand it. I’ll appreciate if someone used it before and could give a bit more description on it.

Sorry for keep sending possible stupid questions.

Thanks again,
Song

Hi,

I am hoping to get some advice from you on the following task.

Basically we are trying to implement a pipeline reading (by a customer GStreamer element) raw frame data from disk, pass to ffmux_mov, which generates mp4, and passes to a fdsink.
If the fdsink is associated with a disk file, we get a mp4 file and everything is fine.

However, we were asked to associate the stdout to the fdsink so that the mp4 is not created under the disk, but directly get outputted to the stdout as an http response to the Client. This doesn’t work. The main issue is that the ffmux_mov tries to send SEEK events to the fdsink to set write-pointers to different positions of the mp4 to handle headers, trailers etc. As the stdout is not a seekable resource, this wouldn’t work.

I wonder has anyone tried this before.
Have I missed something?
Can ffmux_move be modified to work in the above scenario?
Is there other good ways to do the above, such as using other containers instead of mp4?
Any advice is highly appreciated.

try to use mp4mux and set streamable=true, should work,

Nicola



Apologise if I send to the wrong place. I’m new to GStreamer and only registered to the mail-list yesterday.
