Странно, при таких же параметрах ffmpeg у меня в stsc получилось:
stsc
size = 28
type = stsc
entry_count = 1
first_chunk = 1, samples_per_chunk = 1, sample_description_index = 1
У тебя:
stsc
size = 40
type = stsc
entry_count = 2
first_chunk = 1, samples_per_chunk = 426, sample_description_index = 1
first_chunk = 2, samples_per_chunk = 183, sample_description_index = 1
Попробуй файл в приложении.
