RTP player when built with portaudio V18
After ironing out a cmake build issue with the older portaudio V18[1], I can
see that the lines are drawn "correctly" over time. It is not entirely correct
since it does not clear the old lines.
As for the value of idx with portaudio V18, it varies. I have seen 44.9k,
39.8k, etc.:
917 idx = Pa_StreamTime( pa_stream ) - rtp_channels->pause_duration
- rtp_channels->out_diff_time - start_index;
(gdb)
924 if ( (rtp_channels && (!rtp_channels->stop) &&
(!rtp_channels->pause)) && (idx > rtp_channels->max_frame_index) ) {
(gdb) p idx
$1 = 44906
In the V19 code, it is always -265. To fix this bug:
1. Investigate the calculation of idx.
2. Investigate why the old line is not cleared.
