That solve it only partly. Both players play it with the wanted duration, but they display a file length of 0 seconde. I get the same problem with the following command line: gst-launch-1.0 audiotestsrc is-live=1 ! flacenc ! filesink location=generated.flac But I get the correct duration display with: gst-launch-1.0 -e audiotestsrc is-live=1 ! flacenc ! filesink location=generated.flac Another issue is that ideally, I want to be able to use such a pipeline with gambas: gst-launch-1.0 -e audiotestsrc is-live=1 ! audio/x-raw,channels=2,rate=48000 ! flacenc ! filesink location=generated.flac and if I try something like: $hAudio["is-live"] = "1" $hRaw = New MediaControl($hPlayer, "audio/x-raw") $hConv = New MediaControl($hPlayer, "flacenc") $hOutput["location"] = "wavegenerator.flac" $hOutput["append"] = "1" $hAudio.LinkTo($hRaw) $hRaw.LinkTo($hConv) $hConv.LinkTo($hOutput) it fail at $hRaw = New MediaControl($hPlayer, "audio/x-raw") How I can get it to work? If I comment out $hRaw = New MediaControl($hPlayer, "audio/x-raw"), the line '$hOutput["append"] = "1"' make the content of the generated file to survive when quitting the program, but as alsaplayer still display a duration of 0, I am not sure it is the right fix. It look more like a workaround.
