Add support for camera with realtime source timestamp.

[ThibaultBee]

On device with realtime source timestamp, it is not possible to read stream from ffmpeg.
On ffmpeg side, the following errors happen:

See #11 (comment)

[ThibaultBee]

@RobbieEllias can you test #13?
I assume that a phone camera sources are either realtime either unknown. It can't have one camera with a realtime ts source and another with an unknown ts source.

[RobbieElias]

Just tested, it doesn't work.

[ThibaultBee]

Ok, I must have missed something.
I added a commit with a lot of logcat trace. Can you test it and send me your logcat content?

[RobbieElias]

Here you go: logcat.txt

[ThibaultBee]

Audio timestamp source is also odd.
Sorry, you will have to retest https://github.com/ThibaultBee/StreamPack/tree/feature/camera_realtime_ts_source.

[RobbieElias]

Here you go: logcat.txt

The video played, but the audio was a little out of sync.

[ThibaultBee]

Yeah :) the stream is working!

This look likes another issue (maybe SRT configuration?) but your logcat seems alright. Do you have error on ffmpeg logs?
What do you mean by a little out of sync? Few ms? 1-10 seconds? Is it always the same time shift ?

By the way, I also removed Log.i from the branch, because it might generate issue in A/V sync.

[RobbieElias]

It's only off by a few ms. I get a lot of errors in ffplay:

[RobbieElias]

If I set the audio sample rate to 44.1 kHz, the A/V sync issues are fixed. So there's an issue with converting the sample rate I guess.

[ThibaultBee]

At least, timestamp issue is resolved. I merged #13.
They are no sample rate conversion in StreamPack. The only thing that could be wrong is the way AAC ADTS is built. I will check what could be wrong with the audio sample rate and I might open another issue.
Thanks for your help!
