It's possible caps are not propagated to the encoder if not directly connected to the filesrc. Moreover, I didn't catch where you're setting the blocksize property in your filesrc to "size". ..Snip.. > There is something wrong or missing in this function? How can I make > what I want to work? See my comments above ;) P.S. Maybe you could attach (or better copy to pastebin) the output when setting GST-DEBUG to 2 from the shell prior executing your binary.
