Hello, I use Icecast with the CentovaCast running on Centos when it is switched between live and autoDJ ffmp3 the player keeps crashing (plays about 2 seconds and stopped 2/2). I've tested the same player the same songs on another service and the transition occurs without problem, so I guess it could be an option that is not configured properly.
Note: apologies if this subject has been approached but have not found and sorry for my english, I am Brazilian.

obviously a crash is something the ffmp3 guys have to deal with. As for something that icecast is doing to trigger it, well it's hard to say. Assuming the format settings are the same, you did not say, then check with an alternate player so see if the same transition has some disruptive effect, the alternate player may not crash but could reconnect for example.

Thanks for the quick answer, as I tested the same player on another installation of icecast (a streaming company) is not assumed that the problem is something with my setup icecast, I realized that my installation uses version 2.3.2 and version used by the company is 2.3.2-kh30, it could have been corrected in this subversion?

It is possible that ffmp3 is sensitive to the frame alignment over a switchover. As icecast 2.3.2 does not align on mp3 frames then the switch over point is usually not on a frame boundary, in the later kh builds the input is aligned on boundaries and therefore would not require a re-sync for the player.
