| Post subject: | R5.5 breaks h264 codec under transcode |
Hoping someone can help me out. When I attempt to transcode from VOB to H264 using the transcode program: Code: transcode -i filename.vob -I 5 -g 720x480 -f 0,1 -M 2 -y ffmpeg -F h264,null -A -N 0x2000 -o /dev/null --print_status 20 --color 0 -R 1,x264_2pass.log I get the following error: Code: transcode v1.0.2 (C) 2001-2003 Thomas Oestreich, 2003-2004 T. Bitterberg [transcode] (probe) suggested AV correction -D 0 (0 ms) | AV 0 ms | 0 ms [transcode] auto-probing source filename.vob (ok) [transcode] V: import format | MPEG (V=null|A=null) [transcode] V: AV demux/sync | (2) initial MPEG sequence / enforce frame rate [transcode] V: import frame | disabled [transcode] V: de-interlace | (mode=5) interpolate scanlines / blend frames [transcode] V: bits/pixel | 0.000 (unknown) [transcode] V: decoding fps,frc | 23.976,1 [transcode] V: multi-pass | (mode=2) reading data (pass2) from x264_2pass.log [transcode] V: Y'CbCr | YV12/I420 [transcode] A: import | disabled [transcode] A: export | disabled [transcode] V: encoding fps,frc | 23.976,1 [transcode] A: bytes per frame | 0 (0.000000) [transcode] A: adjustment | 0@1000 [transcode] V: IA32/AMD64 accel | sse (sse 3dnowext 3dnow mmxext mmx asm C) tc_memcpy: using sse for memcpy [transcode] V: video buffer | 10 @ 0x0 [import_null.so] v0.2.0 (2002-01-19) (video) null | (audio) null [export_null.so] v0.1.2 (2001-08-17) (video) null | (audio) null [export_ffmpeg.so] v0.3.13 (2004-08-03) (video) Lavc51.11.0 | (audio) MPEG/AC3/PCM [export_ffmpeg.so] Could not find a FFMPEG codec for 'h264'. [transcode] warning : (encoder.c) video export module error: init failed [transcode] critical: failed to init encoder I think the error is in the compliation of ffmpeg under R5.5: Code: sh-3.1$ ffmpeg -version

Is anyone else having this issue? Can I simply download the SVN for ffmpeg, build it using the right flags, and install it, or would I need to rebuild transcode as well with the new libraries? Thx |

You can get x264 by enabling the debian-multimedia apt sources and installing ffmpeg from there. See the following page for some instructions on doing this: http://knoppmyth.net/phpBB2/viewtopic.p ... 0815315699 |

I went back and revisited the process. The following is a condensed version of what I posted in that thread: Edit /etc/apt/sources/conf and uncomment the following lines: Code: deb http://www.debian-multimedia.org unstable main deb-src http://www.debian-multimedia.org unstable main Run the following commands as root: Backup a couple configuration files: Code: cp /etc/ffserver.conf /etc/ffserver.R5.5-orig cp /etc/mplayer/mplayer.conf /etc/mplayer/mplayer.R5.5-orig Perform the upgrade--you have to upgrade ffmpeg, mplayer and transcode together (along with a few dependencies) Code: apt-get update apt-get remove transcode mplayer apt-get install ffmpeg libavcodec51 libavdevice52 libavformat52 libavutil49 transcode mplayer You will be asked if you want to change configuration files for ffserver and mplayer. Press Y to accept and examine changes from backups made above if you find any problems. Finally, check ffmpeg version to confirm change: Code: ffmpeg -v

The directions from Aug.2008 don't work any more. There are dependency errors. I found that if you change the sources to SID rather than UNSTABLE or even STABLE, the dependency problems are fixed. /etc/apt/sources.list Code: deb http://www.debian-multimedia.org sid main deb-src http://www.debian-multimedia.org sid main then Code: apt-get update
apt-get remove transcode mplayer apt-get install ffmpeg transcode mplayer |

I am looking for a what all the lines in R5.5 sources.list should look like now... |
