I've experimented with changing AddTvEncoderFilter in

TvLibrary\Implementations\Analog\Components\Encoder.cs

so that it searches for encoding filters of FilterCategory.MediaEncoderCategory as well as of AMKSEncoder

category (relevant code snippet below).

I use this to enable "MCE-style" software encoder filter (video/audio input , mpeg2 out in single filter) with my

analog SW-encoding card, and it works well on my system.

I'm aware you want to restrict the use of SW-encoding filters to those known to work, but I'm wondering if there's

any particular reason SW/HW-filters are treated differently, i.e. HW-filters in AddTvEncoderFilter and SW-filters in

Add(Audio||Video)Compressor? From the system's point of view, there shouldn't be any difference between the

two types, should there?

To be clear, this is a general question, not really a suggestion for code change.

[CODE]

private bool AddTvEncoderFilter(bool matchPinNames, bool mpeg2ProgramFilter, IFilterGraph2 _graphBuilder, Tuner _tuner, TvAudio _tvAudio, Crossbar _crossbar, Capture _capture)

    {

      Log.Log.WriteFile("analog: AddTvEncoderFilter - MatchPinNames: {0} - MPEG2ProgramFilter: {1}", matchPinNames, mpeg2ProgramFilter);

      bool finished = false;

      DsDevice[] hwDevices;

      DsDevice[] swDevices;

      DsDevice[] devices;

        // first get all hw/sw encoder filters available on this system

      try

      {

          swDevices = DsDevice.GetDevicesOfCat(FilterCategory.MediaEncoderCategory);

        hwDevices = DsDevice.GetDevicesOfCat(AMKSEncoder);

        devices = new DsDevice[hwDevices.Length + swDevices.Length];

        int idx = 0;

        for (int i = 0; i < hwDevices.Length; i++)

        {

            devices[idx] = hwDevices[i];

            idx++;

        }

        for (int i = 0; i < swDevices.Length; i++)

        {

            devices[idx] = swDevices[i];

            idx++;

        }

       

        devices = DeviceSorter.Sort(devices, _tuner.TunerName, _tvAudio.TvAudioName, _crossbar.CrossBarName, _capture.VideoCaptureName, _capture.AudioCaptureName, _videoEncoderDevice, _audioEncoderDevice, _multiplexerDevice);
