[FFmpeg-user] -movflags faststart revisited

I retried to use this flag as it was indicated in a previous response by a
user.
Sorry that I was unable to continue on the original thread, because the
gmail web
interface deletes original message sent to this list by the OP, when the OP
deletes the
response from the list.

So, even though I corrected the usage of the flag, I am still unable to
play the output
file before ffmpeg finishes the transcoding :( :(
