I would recommend to try and write a GStreamer encoder element,
based on the GstVideoEncoder class. This is generally simpler and
less complicated than the FIFO approach, especially for real-time
encoding. If this really is not possible for whatever reason, then
a FIFO could work. Be sure to use the h264parse element to group
input data into frames. Example: gst-launch-1.0 filesrc
location=/tmp/my-fifo ! h264parse ! matroskamux ! filesink
location=encoded-video.mkv<br>

These use the Freescale's VPU wrapper library in order to

You could perhaps use the same aproach.<br>

<br>
I have a proprietary encoder on a SoC that compress with
H264. I am thinking about wrapping the whole encoding
process in a single source that outputs compressed
frames.<br>
<br>
My idea is to have a fifo that is filled by the
proprietary code and that is read by a gstreamer element
that injects nal units in the gstreamer pipeline.<br>
<br>
Do you think is doable?<br>
<br>
Is there any element in gstreamer that can help me do
this?<br>
<br>
Thank you<span class="HOEnZb"><font color="#888888"><br>
