The input file has 1 video stream and 4 identical (as far as the CAPS are concerned) audio streams. I am currently using GStreamer/GES mingw x64 1.18.1 on the Windows platform.<br></div><div><br></div><div>As the documentation suggested, I wrote a signal handler for the GESTimeline's "select-tracks-for-object" signal, and I've verified that it is working as expected with returning a NULL for GESTrackElements that are not the audio stream I want, while returning a GPtrArray with the timeline's audio track when it is the audio stream I want.</div><div><br></div><div>The problem though is that only the 1st audio stream of the input file is ever chosen for the output. I've been looking through the GES source code, and it appears that when
<code><span>ges_source_create_topbin</span> <span></span></code> in GESSource is called for the audio, it will always just look for the first pad created when the "pad-added" signal is on uridecodebin is called; this made me wonder if something in the creation of uridecodebin itself was supposed to be responsible for selecting the correct audio stream. However, the only thing I can find there is the "caps" property which does restrict the streams, but since my 4 audio streams all have identical CAPS, this doesn't end up being a restriction.</div><div><br></div><div>My question is first, am I missing something obvious that would make this work as expected? If not, aside from code changes to GESSource/UriSource/AudioUriSource, is there something tricky I can do like finding the uridecodebin, intercepting the pad-added signal before it gets to the GESSource, and only letting it through when getting to the pad that I want to be connected?</div><div><br></div><div>Thank you, responses are much appreciated.</div><div>--Chris<br></div></div>
