<html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> </head> <body> Hi, I expect you should be able to create a MJPEG from JPEG buffers in memory if you write an application with an appsrc in order to feed your buffers in. Simply for MJPEGs you should be able to do something like this: <code>videtestsrc ! <SRC_CAPS> ! queue ! videoconvert ! jpegenc ! avimux ! filesink location=<LOCATION></code> Once you have that working you can change into feeding your own frames in with an appsrc: <code>appsrc ! <SRC_CAPS> ! queue ! avimux ! filesink location=<LOCATION></code> Look into the appsrc tutorials for how to feed data into it. I don't really know much about MP4 so I cannot help there. But I don't expect you can get around decoding the JPEG and encoding to H264.

I have jpeg files in memory (byte[] in terms of C#), how to transform them into mjpeg file? Can you help me with pipeline for that? Can it be done in memory, without dumping jpeg files? to disk? ? Same problem, but now I need mp4 file.?At least I can see way to transcode mjpeg into mp4, but maybe it ?could be done in a more straight way ??from jpegs to mp4? ? Thanks in advance.</pre> </blockquote> <pre class="moz-signature" cols="72">-- Best regards / Med venlig hilsen “Marianna Smidth Buschle”</pre> </body> </html>
