Hi:

I have a newbie question about the DXVA feature of elecard's AVC filter. Does it work with all graphic cards with DXVA? if not, what are the brands/lines that have been tested with the filter?

Another question is, how many instances of players (with DXVA support) can be launched at the same time? say, if we have an application with 6 players, can they all benefit from DXVA? if DXVA can only be used in one instance, then what would happen to the rest of the players?

Thanks in advance.

Hi:

My company has licensed mpeg2 and avc filters from Elecard. we need to support a customer who requires closed caption.

1. Does elecard avc plugin support closed caption with ITU T.35 standard?

2. Both "Elecard MPEG-2 Video Decoder" and "Elecard AVC Video Decoder" have ~CC Out pin exposed even when there's no cc data in the video stream. Since I do not want to render the ~CC pin when it is not necessary, is there a way to detect if closed caption is present so that i can decide whether to include line21 filter in the graph?


Thanks in advance.

i have a h264 over mpeg transport file, the audio is AAC. i can build a filtergraph with "Elecard MPEG Demultiplexer", but for some reason, when i tried to connect my push source filter to "Moonlight MPEG Push Demultiplexer", only the video pin is exposed at the demux filter.

but the push demuxer works well with the other h264 files which audio is  mp3.

is there a limitation that the push demuxer cannot parse the AAC audio stream?
