<html> <head> <style></style> </head> <body class='hmmessage'><div dir='ltr'> Hi all,<br> <br>I know that someone has already asked for this, but I can't find a solution.<br>I need to introduce in the audio stream of one branch of my pipeline a variable delay.<br>I try using an audiofirfilter but I think it's not a good solution since the kernel of the filter could have even thousands of elements, but only the last of them is different from zero. So it seems a waste of resources, and also sometimes I get an error while playing. Could the error be because the kernel is too big? Or because I modify the kernel while playing?<br>Could a solution be use a data buffer probe or an identity element in order to modify the timestamp of the buffer? But there are two problems: <BR>gst_buffer_is_metadata_writable tells me that the data is not writable, and anyway even if I modify the timestamp I don't get any effect.<br><BR>is there anybody who has had the same problem and has solved it in some way?<BR><br><BR>Thank you for your help in advance,<br>Stefano </div></body> </html>
