I think I am close (maybe a bit farther than I'd like to admit) to having a working ATSC DTV transcoding "hack" in place.

That being said, I can get ffmpeg to stream video to stdout (which can be piped to mplayer, etc), however I am having a hard time getting Subsonic to handle it.

I've added a custom file handle (.chan) to the video files list, and added a transcoder config for .chan files as the following:

Code: Select all

Name,ConvertFrom,ConvertTo,Step1
flv/h264 video,chan,flv,ffmpeg -i /dev/dvb/adapter0/dvr0 -async 1 -b 1000k -s 480x360 -ar 44100 -ac 2 -v 0 -f flv -vcodec libx264 -preset superfast -threads 0 -

Note: I took the variables out of the equation as I'm only looking to stream one channel/freq which is already tuned via azap.


When I click the file, I get video/jplayer rendered, but see the folllowing:

Code: Select all

Video not found or access denied: /subsonic/stream?id=111285&maxBitRate=1000&timeOffset=0&player=1

Also, the following is logged to /var/subsonic/subsonic.log:

Code: Select all

[2012-07-04 11:52:28,035] WARN StreamController - Unknown duration for KCAL9. Unable to estimate transcoded size.

Note: KCAL9.chan is the name of empty txt file I created.

Of course, video transcoding using ffmpeg works like a charm via other file formats like .avi, etc.


Anyone have any experience with this?
