Logging quality loss events

[oarcas]

Hi all,

I am using VLC to detect (not fix) quality loss in RTP audio streaming. I will use it to automatically score connection quality. The verbose output displays many events, like:

Code: Select all

[000055807da7f730] main audio output warning: playback way too early (-208713): playing silence [000055807da7f730] main audio output debug: inserting 4602 zeroes

For these silences or crackling sounds, it is easy to locate where in the code it happens.

However, there also may appear some popping sounds that have no debug message.

Could somebody give me some hints on how to log (not fix, because they are expected) these additional quality problems? Maybe it is happening at a later stage, like the sound driver (ALSA, etc.)?

Thanks!

Oriol

Hi, popping sound might be underflows in pulseaudio, but I'm not 100% certain. If so, they are logged by the pulseaudio plugin.

Thank you very much!
