Recording pipeline which works on CMD does not in Python

[dgoiko]

This is the bin that actually works to display video/audio on screen for
debugging purposes:

def _bin_stdout(nombrebin="bin-stdout", ignorar_video=False):
    bin_autosink = Gst.Bin.new(nombrebin)
    if not ignorar_video:
        cola = Gst.ElementFactory.make("queue", "cola-video-debug")
        bin_autosink.add(cola)
        ghostpad_video = Gst.GhostPad.new("video-sink",
cola.get_static_pad("sink"))
        bin_autosink.add_pad(ghostpad_video)
        videosink = Gst.ElementFactory.make("autovideosink")
        bin_autosink.add(videosink)
        cola.link(videosink)
    cola2 = Gst.ElementFactory.make("queue", "cola-audio-debug")
    bin_autosink.add(cola2)
    ghostpad_audio = Gst.GhostPad.new("audio-sink",
cola2.get_static_pad("sink"))
    bin_autosink.add_pad(ghostpad_audio)
    audiosink = Gst.ElementFactory.make("autoaudiosink")
    bin_autosink.add(audiosink)
    cola2.link(audiosink)
    return bin_autosink

It's made in the same way than the others, so I guess the problem is within
BIN  creation, and not with the envelope. It's very similar to the playbin
python
tutorial:https://brettviren.github.io/pygst-tutorial-org/pygst-tutorial.pdf,
just using uridecodebin (pads are added properly!)


THIS manually created bin doesnt work either:

def _bin_record_v2(path, nombrebin="bin-grabacion", formato="mkv",
intervalo=600):
    bin_record = Gst.Bin.new(nombrebin)
    nanosegundos = intervalo * 1000000000  # Convertir los segundos en
nanosegs
    # Creamos y preparamos el splitmuxsink.
    # TODO: Lo ideal seria streamearlo direco a otro Gstreamer con
recepción, y que este lo grabe con tranquilidad en el disco duro.
    #splitmuxsink = Gst.ElementFactory.make("splitmuxsink",
"splitmuxsink-grabacion")
    splitmuxsink = Gst.ElementFactory.make("filesink",
"splitmuxsink-grabacion")
    #splitmuxsink.set_property('max-size-time', nanosegundos)
    extension_file = "mkv"
    encoder_video = Gst.ElementFactory.make("x264enc")
    encoder_audio = Gst.ElementFactory.make("opusenc")
    muxer = Gst.ElementFactory.make("matroskamux")
    splitmuxsink.set_property('location', path + "." + extension_file)
    # Añadir el encoder al bin
    if encoder_video is not None:
        cola_video = Gst.ElementFactory.make("queue",
"cola-video-grabacion")
        bin_record.add(cola_video)
        ghostpad_video = Gst.GhostPad.new("video-sink",
cola_video.get_static_pad("sink"))
        bin_record.add_pad(ghostpad_video)
        videoconvert = Gst.ElementFactory.make("videoconvert",
"converter-video-grabacion")
        bin_record.add(videoconvert)
        cola_video.link(videoconvert)
        bin_record.add(encoder_video)
        videoconvert.link(encoder_video)
    if encoder_audio is not None:
        cola_audio = Gst.ElementFactory.make("queue",
"cola-audio-grabacion")
        bin_record.add(cola_audio)
        ghostpad_audio = Gst.GhostPad.new("audio-sink",
cola_audio.get_static_pad("sink"))
        bin_record.add_pad(ghostpad_audio)
        audioconvert = Gst.ElementFactory.make("audioconvert",
"converter-audio-grabacion")
        bin_record.add(audioconvert)
        cola_audio.link(audioconvert)
        bin_record.add(encoder_audio)
        audioconvert.link(encoder_audio)
