    nuvexport dramatics

    Using a clean install of mythbuntu 9.10 - I had nuvexport working with mencoder. I'd like to use ffmpeg for xvid but it doesn't do that anymore

    Then two days ago, after an update, I think, nuvexport/mencoder started this with every file processed:

    Waiting for mythtranscode to set up the fifos.
    Starting mencoder.
    processed: 38312 of 39161 frames (97.83%), 25.13 fps
    mythtranscode finished.
    processed: 39114 of 39161 frames (99.88%), 25.09 fps

    mythtranscode died early.Please use the --debug option to figure out what went wrong.
    As you can see it doesn't quite finish the job and exits. That means I can't batch process.

    I've tried the --debug option and then executing the commands.
    mkdir -m 0755 /tmp/fifodir_10768/
    The second command
    /usr/bin/nice -n19 /usr/bin/mythtranscode --showprogress -p '0' -c '1002' -s '2009-10-24T22:10:00' -f "/tmp/fifodir_10768/" --honorcutlist 2>&1
    seems to hang at this point:

    2009-10-26 08:32:21.861 Using runtime prefix = /usr
    2009-10-26 08:32:21.862 Using configuration directory = /home/guiguy/.mythtv

    2009-10-26 08:32:22.004 Using protocol version 50
    Essentially I now cannot archive any recording since ffmpeg and transcode won't do xvid etc. Unless there is a more practical way to archive recordings?

    Can any one help?

    Re: nuvexport dramatics

    The second command seems to set up pipes for the third command, so I believe this is expected behaviour (Notice how the output from using the --debug option says "forking").

    That said, when I execute the third command (while the second is still running), I get:

    /usr/bin/nice -n19 transcode -V --print_status 16 --import_asr 3 --export_asr 3 --export_fps 25.000,3 -Z 160x96 -k -i /tmp/fifodir_8774/vidout -p /tmp/fifodir_8774/audout -H 0 -x raw -g 704x576 -f 25.000,3 -n 0x1 -e 48000,16,2 -j 8,10,8,10 -J smartyuv -J yuvdenoise=mode=2 -y xvid,null -N 0x55 -b 128,0,2,0 -R 1,/tmp/xvid.8774.log -w 100 -o /dev/null 2>&1
    [transcode] critical: bad argument for -V/--video_format, should be one of: yuv420p (default), yuv422p, rgb24
    However, if I set the -V argument to yuv420p and remove the "--print_status 16" then it starts processing.... still waiting to see if it turns out ok.

    Edit: It completed and created the output file as expected, but there were some audio warnings and NO audio in the exported file. Output was:

    Re: nuvexport dramatics

    Got mine working for xvid4

    Made the following edits to /usr/share/nuvexport/export/

    • Remove ".' -V'" from line 87 (no longer an option in transcode)
    • Remove ".' --print_status 16'" from line 88 (no longer an option in transcode)
    • Remove "$transcode .= ' -k';" from line 223 (this was making faces have a bluish tinge)
    • Change ".' -H 0 -x raw'" on line 243 to ".' -H 0 -x raw,raw'" so that the audio input is processed
