requested to merge vjaquez/gst-plugins-base:dont-break-stream-no-audio into master
There's a sample in Khronos WebGL conformance test which is a webm container that expresses two streams:
container format: Matroska
language code: en
Nonetheless, the audio stream contains zero frames.
This configuration makes the audio decoder to raise an error in the bus. Using
playbin2 the stream cannot be played at all. With
playbin3 the stream is played and the error is raised at the end.
This MR proposes a change in the audio decoder from raising an error in the bus, to a warning.
