Good afternoon

i'm very interested in WMS, but actually i recodrd tv from HD channel.I try transcoding of wtv files and the normal channells works well , but HD channel are not visible (black screen).
I think is due to the H264 codec.
Will WMS support this kind of transcoding??

Thanks in advance

If the device supports MPEG Transport Stream and H264, try Settings - Transcoder - Profiles - "Movies - DirectShow - WTV (MPEG-TS)" - Edit
find

Code: Select all

if SameText(sVideoMediaSubType, MEDIASUBTYPE_X264_) or 
     SameText(sVideoMediaSubType, MEDIASUBTYPE_x264) or
     SameText(sVideoMediaSubType, MEDIASUBTYPE_AVC1_) or     
     SameText(sVideoMediaSubType, MEDIASUBTYPE_avc1) or
     SameText(sVideoMediaSubType, MEDIASUBTYPE_H264_) or     
     SameText(sVideoMediaSubType, MEDIASUBTYPE_h264) then

Code: Select all

sVideoTrack := 'V_MPEG-2, "%s"'
uncomment

Code: Select all

sVideoTrack := 'V_MPEG4/ISO/AVC, "%s", level=4.1, insertSEI, contSPS'

I try your suggests and i wasn't able to play them.
I try a test of transcod before play and i noticed that on some files transcod works fine and on other doesn't start.
Any suggests to try to solve it?
I'm a step near perfect for me...i want to make me a gift for Christmas and buy WMS

I made some try and i realize that the problems are inside the wtv file.
Some H264 wtv file works well others don't work.
I think it's an audio problem.How can i check before transcode if file is ok??
I'm tryng to remux them with Videoredo but at now i haven't found a solution.
A possible solution is to set (if possible) audio of hd channel different from Dolby Digital (AC3 i suppose)?!?

Thanks, new version "Movies - DirectShow - WTV (MPEG-TS)"
wmvmpegts.zip
(2.62 KiB) Downloaded 670 times
1. Unzip
2. Settings - Transcoder - Profiles - "Movies - DirectShow - WTV (MPEG-TS)" - Delete
3. Load - wmvmpegts.cfg - "Clear ... ?" - No

Transcoding working, the ability to play depends on the device

Maybe later will be a new version "Movies - DirectShow - WTV (MPEG-PS)" with video transcoding.
