Re: [PATCH v2 0/4] MR10864: winegstreamer: Rebase PTS values so the stream starts at zero.

[Elizabeth Figura (＠zfigura)]

```
+    /* Make sure every stream has a buffer. */
+    for (i = 0; i < parser->stream_count; ++i)
+    {
+        GstBuffer *buffer;
+        struct wg_parser_stream *stream = parser->streams[i];
+        buffer = wait_parser_stream_buffer(parser, stream);
+        if (stream->enabled && !stream->eos && !buffer)
+        {
+            GST_ERROR("Failed to get a buffer, stream #%d.", stream->number);
+            goto out;
+        }
+    }
+
```

That's not quite what I meant; rather we should be altering the existing condition so that it just looks like "while (!parser->error && !stream->has_buffer)".
