You can't have a generic pipeline which handles all cases, because if there is only one audio stream but you specified multiple audio transcoding paths, then gst-launch will hang/wait forever for the other audio pads. In other words: you need to write code to handle this. <div><div></div><div class="Wj3C7c"> > I get the following warning messages while running the above pipeline: > > Setting pipeline to PAUSED ... > Pipeline is PREROLLING ... > WARNING: from element /GstPipeline:pipeline0/GstURIDecodeBin:d: No > decoder available for type 'application/x-mpegts-private-section'. > Additional debug info: > gsturidecodebin.c(589): unknown_type_cb > (): /GstPipeline:pipeline0/GstURIDecodeBin:d > WARNING: from element /GstPipeline:pipeline0/GstURIDecodeBin:d: No > decoder available for type 'application/x-mpegts-private-section'. > Additional debug info: > gsturidecodebin.c(589): unknown_type_cb > (): /GstPipeline:pipeline0/GstURIDecodeBin:d > WARNING: from element /GstPipeline:pipeline0/GstURIDecodeBin:d: No > decoder available for type 'application/x-mpegts-private-section'. > Additional debug info: > gsturidecodebin.c(589): unknown_type_cb > (): /GstPipeline:pipeline0/GstURIDecodeBin:d > WARNING: from element /GstPipeline:pipeline0/GstURIDecodeBin:d: No > decoder available for type 'application/x-mpegts-private-section'. > Additional debug info: > gsturidecodebin.c(589): unknown_type_cb > (): /GstPipeline:pipeline0/GstURIDecodeBin:d > WARNING: from element /GstPipeline:pipeline0/GstURIDecodeBin:d: No > decoder available for type 'application/x-mpegts-private-section'. > Additional debug info: > gsturidecodebin.c(589): unknown_type_cb > (): /GstPipeline:pipeline0/GstURIDecodeBin:d > WARNING: from element /GstPipeline:pipeline0/GstURIDecodeBin:d: No > decoder available for type 'private/teletext'. > Additional debug info: > gsturidecodebin.c(589): unknown_type_cb > (): /GstPipeline:pipeline0/GstURIDecodeBin:d </div></div>I don't think those are fatal or related to your problem. You can probably ignore them.
