Bug 190045 – [GStreamer][MSE] Use GObject for GST_TRACE_OBJECT

• Component: WebKitGTK
• Status: RESOLVED FIXED

[Alicia Boya García]

Passing a non-GObject object to GST_TRACE_OBJECT() can be
theoretically misunderstood by the GStreamer logging function, so this
patch avoids that.

Should you also give the pipeline a proper name?

Any suggestion for a useful name?

I've chosen to use "append-pipeline-<type>-<container>-<number>", e.g.: append-pipeline-audio-mp4-0; as it's usually useful to know which pipeline handles what thing.

lgtm otherwise.

Increment should probably be atomic.

AppendPipeline can only be constructed in the main thread. There is even an assertion for that. No need for atomics here.

OK, informal r+ here then.
