If no more comments, I will try to code something to create a pseudo
encoder which run the actual encoding in the separate thread. Thanks

Don't use the functions for searching substrings when all one is
looking for is a char anyway. Given that there is already a standard
library function for "find last occurence of a char in a string" also
allows one to remove a custom loop.

every adaptation set to contain at least one stream, because the loop
exits immediately as soon as the end of the string has been reached,

The WebM DASH manifest muxer uses a loop to parse the adaptation_sets

There is another "return -1" left which might either be invalid data or
an unsupported future extension of the format (e.g. one that does not
have three arrays). I left this as is.

Now we just use one ADTS raw frame to calculate the bit rate, it's
lead to a larger error when get the duration from bit rate, the
improvement cumulate Nth ADTS frames to get the average bit rate.
e,g used the command get the duration like:
ffprobe -show_entries format=duration -i
