Summary: [textoverlay] - silent property looks not well
implemented
Classification: Platform
Product: GStreamer
Version: 0.10.x
OS/Version: Linux
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: gst-plugins-base
AssignedTo: gstreamer-bugs at lists.freedesktop.org

GNOME version: ---
The 'silent' property (to hide and display subtitle during playback)
of official gstreamer textoverlay is also not well implemented.
In textoverlay gst_text_overlay_video_chain(), it just push pure video
data but without consuming the text data. Then
gst_text_overlay_text_chain() will blocked to waiting for the text
data consumed.
For subtitle mixed with av in the same file, the demux will block at
the text demuxing since text data not consumed then will not demux any
followed audio and video data.
