I just installed Mythbuntu 9.04 and i am using a separate partition to store recordings and other media on the same hard drive. I'm also going to use this same partition as the Mytharchive temp directory. I went through all the settings that would pertain to Mytharchive and changed them accordingly. When i want to create a DVD from a recording, i get these error messages;

ERROR: Failed while running ffmpeg to re-encode video.
Command was ffmpeg -v 1 -i "/MythMedia/tivo/Modern Family - 2009-10-14 - 08:00 PM Wednesday.avi" -r ntsc -target dvd -b 4771k -s 720x480 -acodec ac3 -ab 192k -ac 2 -copyts -aspect 4:3 "/MythMedia/mytharchive/work/1/newfile2.mpg" -map 0:0 -map 0:1
************************************************** **********

chmod: changing permissions of `/MythMedia/mytharchive/': Operation not permitted

Any ideas as to why these errors are showing up would be greatly appreciated. thanks.

Did you install the updates?

Looks like there was a bug about this against Karmic before they decided to use 0.22:

I downloaded and installed Mythbuntu on July 15th. It was a fresh machine. There was a temp directory specified in in the settings (/var/lib/mytharchive/temp/), but the directory did not actually exist and I had to create it before MythArchive would work.

Later, Seeker

Ok since my last post i figured out my permissions problem...apparently the solution was too obvious for me to figure it out...i changed the group permissions and everything worked fine.


I also fixed the ffmpeg re-encoding error. I copied the code that Mytharchive was trying to execute:


ERROR: Failed while running ffmpeg to re-encode video.
Command was ffmpeg -v 1 -i "/MythMedia/tivo/<MyVideoHere>.avi" -r ntsc -target dvd -b 4771k -s 720x480 -acodec ac3 -ab 192k -ac 2 -copyts -aspect 4:3 "/MythMedia/mytharchive/work/1/newfile2.mpg" -map 0:0 -map 0:1

I pasted that command into a terminal and got the following error:


Seems stream 0 codec frame rate differs from container frame rate: 30000.00 (30000/1) -> 29.97 (30000/1001)

Unknown encoder 'mpeg2video'

I did a quick search using the Google for Unknown encoder 'mpeg2video' and i found a few threads in a Medibuntu bug tracking forum (https://bugs.launchpad.net/medibuntu/+bug/269997). There was talk of installing some unstripped libraries (libavcodec-unstripped-51, libavdevice-unstripped-52, and others), i did a search for the libraries in the synaptic package manager i and installed them and now it seems to work.

Update #2:

Since my last post, i tried to create a dvd with a recorded show and i got this error message:


drivestatus = ioctl(f,CDROM.CDROM_DRIVE_STATUS, 0)
IOError: [Errno 25] Inappropriate ioctl for device

any ideas?
