Comment (by ryanwilliams):

 In my experience, problem is caused by trim seeking the copy of the stream
 created by the split filter.

 As a work around I suggest you remove the split filter and simply add the
 same input file a second time.

 Alternatively you can experiment by including the fifo filter first on
 each leg of the split.
 warning: This will consume lots of memory.
