[FFmpeg-user] raw input from named pipes, order of frame delivery

[Harald Jordan]

I read the ticket even before writing the first question, but i did not find 
out from the ticket in which build the changes were made. Tried the newest 
version, it writes about the file position after avformat_find_stream_info, 
does that mean it still searches within the pipes?
By the way, i am still trying to figure out wether it works with only audio 
or video.. takes some time to get it done correctly

One day after this version a patch was committed that
claims to fix the hang (ticket #986)
