[QUOTE="tanstaafl, post: 410215, member: 62622"] I've experimented with changing [B]AddTvEncoderFilter[/B] 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); // tanstaafl: no changes beyond this point [/CODE] [/QUOTE]
