Out of curiosity, I tested your code and it does produce files with data in them (~53MB each).</div><div class=""><br class=""></div><div class="">2. I don’t see any MP4 container in your code, so even though the files are suffixed with .mp4, this is actually raw data. I.e: if I attempt to read the file manually I actually see a valid image:</div><div class=""><br class=""></div><blockquote style="margin: 0 0 0 40px; border: none; padding: 0px;" class=""><div class=""><font color="#606060" class="">gst-launch-1.0 filesrc location= PATH3.mp4 ! videoparse width=320 height=240 format=ayuv64 ! videoconvert ! autovideosink</font></div></blockquote><div class=""><br class=""></div><div class="">The format in your setup will likely be different. I assume the code missing the container is because of the simplification you did of your original code.</div><div class=""><br class=""></div><div class="">3. MP4 files __need__ to receive an EOS event in order for them to be playable. In your code, you may send the EOS event in the unlink_cb and wait for it to be received on the bus, before tearing everything down. A simpler alternative is to use another container which doesn’t need the EOS, like Transport Stream (mpegtsmux).</div><div class=""><br class=""></div><div class="">Hope this helps,</div><div class=""><br class=""></div><div class="">Michael</div><div class=""><a href="http://www.ridgerun.com" class="">www.ridgerun.com</a></div><div class=""><br class=""></div><div class=""><div><blockquote type="cite" class=""><div class="">On 9 Apr 2021, at 09:31, stanisbouts <<a href="mailto:stan@scentronix.com" class="">stan@scentronix.com</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div class="">Hi,<br class=""><br class="">I have multiple rtsp sources that are connected to a input-selector object<br class="">with a 'on_pad_added' callback function.
