Gstreamer Filter

[bra...@collabramusic.com]

I'm trying to create a gstreamer filter using the following code:

pipeline.create('GStreamerFilter', {command: 'videorate ! video/x-raw,framerate=25/1'}, (err, videorateFilter) => { });

However doing so generates the following error:

{ [Error: GStreamer filter cannot be created: no element "video"] code: 40001, data: { type: 'MARSHALL_ERROR' } }

I tried to do so using two different filters as well, like below, but that didn't work either.

pipeline.create('GStreamerFilter', {command: 'videorate ! video/x-raw,framerate=25/1'}, (err, videorateFilter) => { });

pipeline.create('GStreamerFilter', {command: 'video/x-raw,framerate=25/1'}, (err, videoFilter) => { });

We're using the RecorderEndpoint to record the video, and I'm trying to make sure the created video has a consistent framerate becuase we were running into issues with Chrome playing back .webm's with drastically changing frame rates.

Any input is much appreciated. Thanks!

Check that command in GStreamer, as that error is what the library spits to us. Probably the syntax is wrong.

Hi,

First of all, you only can create one GStreamer element in a GStreamerFilter.

If you would like to create a videorate you should use command: 'videorate'. 

If you would like to modify the GStreamer caps, you should use a capsfilter element, e.g  command: 'capsfilter caps=video/x-raw,framerate=25/1'

Regards.

David.

Did you ever figure this out? I'm having a similar problem. Thanks. David
