media-video/transcode-1.1.5-r1 is unable to open the ffmpeg export codec, if x264 is selected as video format, apparently because some configuration file is missing, and ffmpeg uses incompatible default settings: $ transcode -H 10 -a 0 -x vob -i vob/001/ -w 875,50 -F h264 -b 0,1,7 -s 1.463 --a52_drc_off -f 25 -Y 8,4,8,4 -B 22,1,8 -R 1 -y ffmpeg,ogg -m avi/001/BluesBrothers-001-00.ogg -o /dev/null --progress_meter 2 --progress_rate 25 transcode v1.1.5 (C) 2001-2003 Thomas Oestreich, 2003-2009 Transcode Team [transcode] V: auto-probing | vob/001/ (OK) [transcode] V: import format | MPEG 2 program stream in (module=vob) [transcode] A: auto-probing | vob/001/ (OK) [transcode] A: import format | AC3 in (module=vob) [transcode] V: AV demux/sync | (1) sync AV at initial MPEG sequence [transcode] V: import frame | 720x576 1.25:1 encoded @ 16:9 [transcode] V: new aspect ratio | 712x400 1.78:1 (-B) [transcode] V: clip frame (->) | 704x384 [transcode] V: bits/pixel | 0.129 (low) [transcode] V: decoding fps,frc | 25.000,0 [transcode] V: multi-pass | (mode=1) writing data (pass 1) to divx4.log [transcode] V: video format | YUV420 (4:2:0) aka I420 [transcode] A: import format | 0x2000 AC3 [48000,16,4] 384 kbps [transcode] A: downmix | 4 channels -> 2 channels [transcode] A: export format | 0x55 MPEG ES Layer 3 [48000,16,2] 0 kbps [transcode] V: export format | unknown (module dependant) [transcode] V: encoding fps,frc | 25.000,3 [transcode] A: bytes per frame | 7680 (7680.000000) [transcode] A: adjustment | 0@1000 [transcode] A: rescale stream | 1.463 [transcode] V: IA32/AMD64 accel | sse3 sse2 sse 3dnowext 3dnow mmxext mmx cmove asm [transcode] V: video buffer | 10 @ 720x576 [0x2] [transcode] A: audio buffer | 10 @ 48000x2x16 [import_vob.so] v0.6.1 (2006-05-02) (video) MPEG-2 | (audio) MPEG/AC3/PCM | (subtitle) [export_ogg.so] v0.0.5 (2003-08-31) (video) null | (audio) ogg [export_ffmpeg.so] v0.3.18 (2008-11-29) (video) Lavc52.66.0 | (audio) MPEG/AC3/PCM [import_vob.so] tccat -i "vob/001/" -t vob -d 0 -S 0 | tcdemux -M 1 -a 0 -x ac3 -S 0 -d 0 | tcextract -t vob -a 0 -x ac3 -d 0 | tcdecode -x ac3 -d 0 -s 1.000000,1.000000,1.000000 -A 1 [import_vob.so] tccat -i "vob/001/" -t vob -d 0 -S 0 | tcdemux -s 0x80 -x mpeg2 -S 0 -M 1 -d 0 | tcextract -t vob -a 0 -x mpeg2 -d 0 | tcdecode -x mpeg2 -d 0 -y yuv420p [export_ffmpeg.so] Using FFMPEG codec 'h264' (FourCC 'h264', H264 (avc)).

Created attachment 234305 [details, diff] patch adding video preset support Attached patch was submitted to the transcode-devel mailinglist. It adds ffmpeg preset support to transcode, which should fix this issue.
transcode-devel silently discards emails from not subscribed senders. The email now arrived at: http://www.mail-archive.com/transcode-devel@exit1.org/msg01001.html
Posted a bump in transcode-devel, no reply so far.
After reading http://www.mail-archive.com/transcode-devel@exit1.org/msg01003.html i´m thinking maybe we should file a bug against dvd::rip so they patch the call to transcode to make use of the new native api?
Created attachment 256983 [details] modified ebuild including the patch a modified ebuild for the lazy, incorporating daniels patch.
Okay, with the patch applied i get this: [export_ffmpeg.so] Using FFMPEG codec 'h264' (FourCC 'h264', H264 (avc)).

I really don´t know if this is related, the exact same settings used to work before the x264 ffmpeg preset problem appeared. BPP Value = 0.15 2-pass encoding set reuse log set framerate set to 25 zoom to full frame container: ogg
Verified that this patch is included in the 1.1.7 release. So, closing as FIXED
I´ve just merged transcode-1.1.7 and it still fails. Added bonus: it segfaults now. I´m attaching a full log...

Created attachment 317089 [details, diff] Fix invalid free when preset file not found The segfault was occurring because of an invalid free on a constant string right before the program quit anyway. This patch copies the name with av_strdup so it can be freed, which is consistent with the behavior that occurs if the user supplies a preset for ffmpeg in ffmpeg.cfg The patch also changes the error message so the user can tell it was the missing preset file which caused the program to terminate. I've only tested this with ffmpeg 0.11 and my patch in bug 419551
