 Posted: Sat May 12, 2007 4:30 pm Post subject: Dvd-slideshow error |
 |
|
It seems that when dvd-slideshow passes parameters to ffmpeg to multiplex the audio and video together it is not in the correct format.
kmedia factory also generates the same error in ffmpeg.
I believe the issue is when the bitrate for the audio is set as -b 224 it must now be -b 224k or some thing like that.
Anyone know how to approach solving this problem.
THanks |

The following pulls any instance of ffmpeg that uses -b in the dvd-slideshow files and dumps it to screen.
| Code: | | grep "ffmpeg.* \-b " `equery files dvd-slideshow` |
From there you can work out what the sed replace syntax would be to add the "k" after the video bitrate | Code: | grep ffmpeg /usr/bin/dvd-slideshow|grep "\-b "|sed 's/-b $video_bitrate/-b ${video_bitrate}k/g'
grep ffmpeg /usr/bin/dvd-slideshow|grep "\-b "|sed 's/-b 700 -qm/-b 700k -qm/g' |
Check the only instances of what you are going to replace are the ones you want to (they should be but...) | Code: | | grep "\-b 700 -qm\|\-b \$video_bitrate" /usr/bin/dvd-slideshow |
All OK? Now, you can add the two sed expressions together and make
| Code: | | sed -i 's/-b 700 -qm/-b 700k -qm/g; s/-b $video_bitrate/-b ${video_bitrate}k/g' /usr/bin/dvd-slideshow |
which should fix it. Once it's done (assuming it works) save the expressions somewhere, so next time you emerge dvd-slideshow you don't have to do it all again from scratch.
EDIT:You may have to repeat for -maxrate too, I'm not too sure. | Code: | | sed -i 's/ -maxrate\( [0-9]*\) / -maxrate \1k /' /usr/bin/dvd-slideshow |

I was wrong about the -b it was -ab; anyway. I am a little lost with your help.
here is the output of the command you recommended.
| Code: | mythtv@wbrokow1 ~ $ grep "ffmpeg.* \-ab " `equery files dvd-slideshow`
/usr/bin/dvd-encode: nice ffmpeg -i "audio.wav" -y -vn -ab 192 -acodec ac3 -ar 48000 -ac 6 audio.ac3
/usr/bin/dvd-encode:# ffmpeg -i "$filename" -y -vn -ab 192 -acodec ac3 -ar 48000 -ac 6 audio.ac3
/usr/bin/dvd-encode: ffmpeg -i "audio.wav" -y -vn -ab 192 -acodec ac3 -ar 48000 -ac 6 audio.ac3
/usr/bin/dvd-menu: ffmpeg -i "$tmpdir/audio.wav" -vn -y -ab 192 -acodec ac3 -ar 48000 -ac 6 "$tmpdir/audio.ac3" >> "$logfile" 2>&1
/usr/bin/dvd-slideshow: ffmpeg -i "$tmpdir/audio1.wav" -y -vn -ab 192 -acodec ac3 -ar 48000 -ac 6 "$tmpdir/audio1.ac3" >> "$outdir/$logfile" 2>&1
/usr/bin/dvd-slideshow: ffmpeg -i "$tmpdir/audio1.wav" -vn -ab 192 -acodec ac3 -ar 48000 -ac 6 "$tmpdir/audio1.ac3" >> "$outdir/$logfile" 2>&1
/usr/bin/dvd-slideshow: ffmpeg -i "$tmpdir/audio2.wav" -vn -ab 192 -acodec ac3 -ar 48000 -ac 6 "$tmpdir/audio2.ac3" >> "$outdir/$logfile" 2>&1

Now exactly what do I type to get the "k" next to the bitrate ?
Thanks so much. |

| Code: | sed -i 's/-ab 192 -acodec/-ab 192k -acodec/g' /usr/bin/dvd-encode
sed -i 's/-ab 192 -acodec/-ab 192k -acodec/g' /usr/bin/dvd-menu
sed -i 's/-ab 192 -acodec/-ab 192k -acodec/g' /usr/bin/dvd-slideshow |
I'll see if I can make human readable enough to understand | Quote: | | sed(stream editor) -i(edit file in place) 's(substitute)/find this text/replace with this text/g(every occurence)' /file/to/edit |
I don't know what dvd-slideshow version you are using, but mine has a bunch of '$audio_bitrate' used with ffmpeg too. |
