Hi ejurgensen,

I'm trying to use forked-daapd on Odroid-C2 board based on armbian distrib.

Here is the behaviour I'm observing: 1/ Starting playback on Airplay speaker is okay 2/ after 4 seconds, playback stops 3/ If I try to play mp3 network stream with a remote PC it starts, but stops also after 4 seconds with following errors (from vlc):

main error: ES_OUT_SET_(GROUP_)PCR is called too late (pts_delay increased to 1000 ms)
main error: ES_OUT_RESET_PCR called

4/ If I try again the mp3 network stream, I get the same result as point 3 5/ After 9 minutes playback stops

Here are some log I'm getting in forked-daapd during playback:

I tried with different formats (http mp3/local flac/pipe using avconv) with the same result.

If you have some advices where to look for debugging?

Regards,

Loic

A few questions: What version of forked-daapd? The log output appears to be from a http stream - could you attach the log from a normal file, and with just regular Airplay?

LoloVTS commented 8 years ago

I've updated from today master branch.

Find attached logs for a mp3 file playback.

forked-daapd.log.txt

I did another test: when trying to output to a shairplay based device, instead of only few second playing, the file is playing but at a slower rate. The 4:24 long song lasts 5:28.

Regards

Could be an issue with the system clock resolution? If the resolution is longer than 7981859 ns then this might happen. Forked-daapd tries to detect the system resolution, but it is not always reliable.

Here is an experiment you could try: Remove line 3996 in player.c ("#if defined...") and the "endif" on line 4002. Then test if it makes a difference. Please take care to actually test with the modified binary! You could add a little log message or something to make sure of that.

Awsome, this is working fine with the modification!
