            Bug ID: 60512
           Summary: wmvread testcase:
                    IWMReaderAdvanced::GetMaxOutputSampleSize() on the
                    asynchronous WMVCore reader fails with E_NOTIMPL
           Product: Wine
           Version: 10.0
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Keywords: source, testcase

wmvread.c (testcase)

Some video players open WMV/ASF files with the asynchronous WMVCore reader
(WMCreateReader() + IWMReaderCallback) and call
IWMReaderAdvanced::GetMaxOutputSampleSize() on the video output before starting
playback, to size their buffers. In Wine this method of the asynchronous reader
is a stub:

  fixme:wmvcore:WMReaderAdvanced_GetMaxOutputSampleSize (...)->(0 ...)

It returns E_NOTIMPL (0x80004001) and leaves the size at 0. A player that
checks the result stops there and never plays the file, although Wine can open
and decode it: the testcase below plays the same file to the end right after
the failed call.

The synchronous reader already implements the equivalent
IWMSyncReader::GetMaxOutputSampleSize(); only the asynchronous reader
(dlls/wmvcore/async_reader.c) is missing it.

Steps to reproduce:
1. Build the attached wmvread.c: x86_64-w64-mingw32-gcc -municode wmvread.c
-lole32 -luuid -o wmvread.exe
2. Create a small WMV file: ffmpeg -f lavfi -i testsrc=size=640x360:rate=25 -f
lavfi -i sine=frequency=440 -t 3 -c:v wmv2 -b:v 1M -c:a wmav2 test.wmv
3. wine wmvread.exe test.wmv

Expected: GetMaxOutputSampleSize returns S_OK and the maximum size of the video
output samples, as documented for IWMReaderAdvanced::GetMaxOutputSampleSize
(not verified on Windows by me).

Actual:
  IWMReaderAdvanced::GetMaxOutputSampleSize(0) hr 0x80004001, size 0
  ...
  video samples 75, audio samples 65, other 0

Tested with wine-11.16-1379-g5b6b85421c2 (current git, after 11.19, unmodified,
clean prefix, no DLL overrides) and with Wine 10.0 and 11.0: same result.
Complete terminal output attached.

I first saw this with a video application that plays WMV9 (WMV3) streams
through this reader: it stops right after this call and plays nothing.
GStreamer's WMV decoders are installed (gstreamer1.0-libav 1.28.2, avdec_wmv3
available), and the WMV3 stream does get decoded to I420 when the reader runs.

System: Ubuntu 26.04.1 LTS x86_64, GStreamer 1.28.2 with plugins
base/good/bad/ugly/libav.
