[PATCH v5 0/4] MR2387: Draft: winegstreamer: Use codec format in stream_props_GetMediaType.
According to the tests in 23b72ad, when we are reading a compressed stream, the type returned by `stream_props_GetMediaType()` should reflect compressed format even if we finnally output uncomressed data. For example, if we use wmvcore reader to read a WMV3 stream and output RGB24, the format information returned by `stream_props_GetMediaType()` should be WMV3, not RGB24.
This patch set is marked as draft now, because PATCH 2 and PATCH 3 is affected by 3e8936a2 in MR !2258. So I'll submit a newer version of this after !2258 get merged.
-- v5: winegstreamer: Use codec format in stream_props_GetMediaType. winegstreamer: Implement amt_from_wg_format_video_wmv. winegstreamer: Implement wg_format_from_caps_video_wmv. winegstreamer: Implement wg_parser_stream_get_codec_format.

@zfigura `amstream:amstream` and `quartz:avisplit` failures are fixed in V5. This patch is ready to be reviewed now.
The winegstreamer API seems fine, but I don't think that approach of retrieving the stream format is quite what we want. I believe the right approach to actually outputting uncompressed data is to use autoplug-continue, so we should use the same signal to find out what the uncompressed format is; that way we know the logic matches. By contrast, this patch could retrieve a compressed format that isn't the "initial" compressed format, or (theoretically?) fail to retrieve a compressed format altogether.
The trick there is matching the pad from autoplug-continue with the pad from pad-added. I've given this some thought and I have two potential ideas here:
(1a) Keep track of pads returned from autoplug-continue in a list, adding a reference to each one. When we get pad-added, walk the list of pads upwards until we find a pad in the autoplug list.
(1b) Keep track of pads returned from autoplug-continue in a list, adding a reference to each one. Install a pad probe on each one as well. When we get pad-added, send a custom query to the downstream pad, and catch it with the pad probe.
(2) Always return FALSE from autoplug-continue for recognized compressed formats. If the format is compressed and we are configured to return uncompressed data, append a second decodebin. Unsurprisingly, GStreamer is designed so that this is actually a pretty reasonable thing to do. There's a (negligible) bit of overhead from the extra bin, but the configuration of elements shouldn't actually change at all. Worth noting is that decodebin will *not* add a multiThat aside, a few extra comments on this queue if there's no parser and use-buffering isn't configured to TRUE; both of these will be the case here and that's what we want (we already have the multiqueue earlier). This also might allow us to toggle compression without recreating the entire wg_parser (by detaching the stream's decodebin), though I haven't fully thought this through and it's not like it matters that much anyway.
The more I think about it, the more I like (2). (1a) seems conceptually ugly and is probably a pain to implement; (1b) is less bad but honestly (2) just seems simpler, both practically and architecturally.

We should create a extra bin for each stream, is that correct? For example, for a ASF file contains both video and audio streams, the first decodebin demux it into video and audio. Then we should create two extra decodebins, one for the video stream, and another for the audio. Is that true?

That's the idea, yes. Note that we'd only create an extra bin for a stream which we recognize the compressed type of, though. If we don't recognize the type we should return true from autoplug-continue, and not hook up an extra decodebin.
