Comment (by isasi):

 sample count , sample duration
 688128 , 0
 0, 0

 The sample duration of in stts atom is zero . I don't know if we need to
 support such file?
 The problem is that there are 688128 audio samples with zero timestamp in
 the audio stream index. With edit list patch we are seeking to timestamp
 zero for the editlist entry, using av_index_search_timestamp which does a
 binary search and lands somewhere in the middle. So half the audio samples
 are removed from the index. Its easy to fix the search function, but don't
 know if we need to support such file which seems to be corrupt ?
