EDL Support about android-tvheadend HOT 4 OPEN

Something like this is what you want for calling out and getting the cutpoints, though it probably needs splitting up a bit, as we would need the addMessageListener just once, but the ability to fetch the cutpoints multiple times:

    HtspMessage message = new HtspMessage();
    message.put("method", "getDvrCutpoints");
    message.put("id", Integer.parseInt(recordingUri.getPath().substring(1)));

    try {
        mConnection.addMessageListener(new HtspMessage.Listener() {
            @Override
            public Handler getHandler() {
                return null;
            }

            @Override
            public void onMessage(@NonNull HtspMessage message) {
                HtspMessage[] cutpoints = message.getHtspMessageArray("cutpoints", null);

                // TODO: Null check...

                for (HtspMessage cutpoint : cutpoints) {
                    Log.d(TAG,"Cutpoint: Type=" + message.getInteger("type"));
                }
            }
        });
        mConnection.sendMessage(message);
    } catch (HtspNotConnectedException e) {
        e.printStackTrace();
    }

As for where it belongs, humm. I suspect TvheadendPlayer is currently the right place for the parsed data to end up - it's the player, and it should be responsible for monitoring the current presentation timestamp, and triggering the seek where necessary. The code above can be called from TvheadendPlayer.buildHtspRecordingMediaSource or maybe TvheadendPlayer.onLoadingChanged.

Looking at the hacky fast forward / rewind code I pushed a few minutes, as well as things like the radio info screens, I'd like to at some point refactor those behavious out of the main player class - but - thats future plans ;)

If you're still stuck, post the code to a PR and I'll see if I can spot anything on Tuesday (holidays until then!)

Awesome, thanks for that. I'll implement EDL support tonight.

I've come across bit of a stumbling block - the Target in #createMessage doesn't seem to get called for me. I suspect this is due to the same issue that means the current time is stuck on 0:00 (the duration seems to be fine). I don't know enough about ExoPlayer to try fixing this though.
