Now the erizo server is not crashing anymore even there are multiple  
streams being recorded. Great work! By the way, I see errors as below from  
the erizo controller log. When I am transcoding the recorded files, ffmpeg  
keeps complaining for the corrupted data and dropping a lot of frames, and  
I was wondering if it is caused by these buffer errors. Any advise will be  
appreciated.

Hi,

Recently we changed the buffer in ExternalOutput to protect from this kind of errors. We will fix it asap.  
Thanks for the heads up!–
