custom graph for playout

[logicom]

Hi,

I have made custom graph for playout, and it works from graph studio.

Is there a way that I could make windows media player to use it, or is there a way to make custom ds filter out of this graph
with the highest merit value so that every time content is being played correctly/on a desirable way either by the system or any other player ?

Regards.

It depends on the graph, what elements are connected. If it's just a simple decoder swap, then adjusting merits should work.

If it's complex, the only way I know of is saving a graph (.grf) and using that in avisynth, and playing the .avs directly in the media player

ok, this is the case:

there is a as02-2011 mxf op1b material. I managed to play audio part by just calling essence file, from mphc and certain demultiplexer.
All audio channels are shown as separate and I can shift with ctr+a for example.

I can also separately play video with mainconcept decoder by opening stream 0 from media folder.

this is similar file structure:

Directory

    MXF_AS02_MPEG2_CBR_1920x1080_25Mbs.mxf
    extra
        MXF_AS02_MPEG2_CBR_1920x1080_25Mbs.xml
    media
        MXF_AS02_MPEG2_CBR_1920x1080_25Mbs_0.mxf
        MXF_AS02_MPEG2_CBR_1920x1080_25Mbs_1.mxf
        MXF_AS02_MPEG2_CBR_1920x1080_25Mbs_2.mxf
        MXF_AS02_MPEG2_CBR_1920x1080_25Mbs_3.mxf
        MXF_AS02_MPEG2_CBR_1920x1080_25Mbs_4.mxf

How I could have this in all in one being able to play from media player ?
this one works:

http://www.avobjects.com/products/splitters/mxf_demultiplexer.html

however, it is deadly expensive, and it provides all audio channels to stereo output - no channel splitter

Any suggestions ?

Regards.

What does mediainfo (view=>text) say about the mxf ?

Did you try another generic non directshow player like VLC ? It should be able to access separate streams

on the top of this I try with professional players like Drastic Preview and it doesn't go fine except with the method I described here.

Did you try another player like vlc, mplayer based like smplayer ?

Since you were able to access each separate audio directly in MPCHC , this suggests there is a free / opensource MXF splitter that can access this particular MXF for audio (either that or you have another MXF splitter installed that it is using). You should be able to look around and construct a graph for audio


So if you have selectable audio working in the graph, and video working in the graph, you can do it with the avisynth workaround

A separate .grf has to be saved for the audio and video (1 video, 1 audio), and the last render pin has to be disconnected

vid=DirectShowSource("video.grf", audio=false)
aud=DirectShowSource("audio.grf, video=false)
AudioDub(vid,aud)

I don't know of any media player that can play .grf files directly

[logicom]

none of the players is working. I will have to look into work around first, and eventually for a solution.

thx poisondeathray

[poisondeathray]

Is this a client thing again, or can you upload a sample ?

OP-1b isn't the common MXF variant, OP-1a is more common as a single package - so it's highly probable that most common tools will have problems

[vhelp]

you can run a simple test to rule out it being an issue with the source material by setting up the scripts outlined above by PDA with a regular video clip, i.e., flv mpg ts avi mp4 and see if they go through. if they do then the problem is with your source video as PDA hinted.

[logicom]

no issue with the source video what so ever. It is just a story with the broadcast formats, not home video, but in a meantime I think I am closer to the solution.
The thing is that mxf have to be read/decoded , split and demux its constituents correctly and respectively to its version. Its constituents, might or might not require recursive demuxing, such as DV with multiplexed audio on the top of other separate mxf audio streams -> video being sent for decoding, while all audio streams/including previously multiplexed , decoded, to be sent to the channel selector and then rendered.

Thanks.
