I haven't yet understood it completely though. What I wanted to do was to provide a sink pad to the muxer where the muxer can link its source pad (=the muxed mp4 stream) to. In the pipeline you provided, the filesink has no sink, does it?</div> <div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> <br> Try:<br> <div><br> gst-launch filesrc location=audio.mp3 ! mp3parse ! mp4mux name=mux<br> </div>filesink location=output.mp4 filesrc location=image.jpg ! jpegdec !<br> x264enc ! mux.<br><br></blockquote><div><br></div><div>I've tried it and the pipeline starts! Thanks a lot again! But: after a few dozen "<mpegaudioparse0> invalid sync" it hangs, the generated mp4 file is empty (0 Bytes). What can I do?
