Hello,

 

 

It would be great to have also recording available for GStreamer integrated into Enigma2.

 

I think (in theory) this can be done directly in GStreamer by dynamically changing the pipeline.

 

When recording enabled then a filesink will be injected on the pipeline, when recording ends then filesink will be removed from pipeline.

 

I would like to hear your ideas on the matter or see good patches ;)

 

Thanks.

Hi athoik,

 

yes, that would be great.

In the gstdvbvideo- and gstdvbaudiosink you can get the demuxed data. But I guess storing demuxed data is not really good, because of sync and playback problems. As you said dynamically adding a filesink right at the beginning of the pipeline should be possible, but then you cannot watch and store the stream at the same time (or??). Or you'll have to open a second pipeline for that.

 

Sorry, I have no time to build patches for it  :( Perhaps in some weeks/months...

Hi,

Actually i was thinking about tee and filesink.

So tee will send one queue to filesink in order recording to occur.

It might work.

Here is an example of tee and filesink https://gist.github....endlers/4113512

Hello,

 

Playbin2 already provides this: http://docs.gstreame...ssive streaming It's like progressive download buffering, but you don't limit file size, so whole media will be downloaded.

 

It's sufficient for simple cases when you only want to watch and download video from the beginning. It's also possible to get progress of downloading file. But if you want to be more flexible, then its not an option.

 

I tested this solution and it worked.

BTW I suppose you'd need to either record the complete stream (not demuxed) or remux it to e.g. a transport stream (if the codec is supported in a ts). There is no use in recording seperate a/v streams.
