Since 155508c6e925f4f2f5e77087a7e1925b3de735ff specifying multiple
bsfs for different streams was broken:
"[bsfs/a=h264_metadata:bsfs/v=h264_metadata]out.mp4|..."
This incorrectly only parsed the first bsfs specification. The reason
for this is that the dictionary is modified in the iterator, hence
invalidating the iterator. The simplest fix for this is to simply
iterate from the beginning in each loop given that the previous entry
is removed.
