Hi, Using transcode 1.1.0 with no great skill I am attempting to extract an ac3 stream directly from title 1, chapter 1 of a DVD. Can I ask some guidance on my obvious failure? I drew most of the syntax from the Transcode FAQs: How can I save the audio track of a DVD directly to a WAVE file suitable for burning onto an Audio CD? http://www.transcoding.org/cgi-bin/transcode?Transcode_FAQ +------------- andrew@skamandros~$ transcode -x null,ac3 -i /dev/dvd -T1,1,1 -a 1 -A -y ac3 -o test.ac3 transcode v1.1.0 (C) 2001-2003 Thomas Oestreich, 2003-2009 Transcode Team libdvdread: Using libdvdcss version 1.2.10 for DVD access libdvdread: Using libdvdcss version 1.2.10 for DVD access [dvd_reader.c] DVD title 1/37: 38 chapter(s), 1 angle(s), title set 2 [dvd_reader.c] title playback time: 02:11:20.10 7881 sec libdvdread: Using libdvdcss version 1.2.10 for DVD access libdvdread: Using libdvdcss version 1.2.10 for DVD access [dvd_reader.c] DVD title 1/37: 38 chapter(s), 1 angle(s), title set 2 [dvd_reader.c] title playback time: 02:11:20.10 7881 sec [transcode] V: auto-probing | /dev/dvd (OK) [transcode] V: import format | MPEG 2 program stream in DVD PAL (module=null) [transcode] A: auto-probing | /dev/dvd (OK) [transcode] A: import format | AC3 in DVD PAL (module=ac3) [transcode] V: AV demux/sync | (1) sync AV at initial MPEG sequence [transcode] V: import frame | disabled [transcode] V: bits/pixel | 0.000 (unknown) [transcode] V: decoding fps,frc | 25.000,3 [transcode] V: video format | YUV420 (4:2:0) aka I420 [transcode] A: import format | 0x2000 AC3 [48000,16,2] [transcode] A: export format | 0x55 MPEG ES Layer 3 [48000,16,2] 128 kbps [transcode] V: export format | unknown (module dependant) [transcode] V: encoding fps,frc | 25.000,3 [transcode] A: language | en [transcode] A: bytes per frame | 7680 (7680.000000) [transcode] A: adjustment | 0@1000 [transcode] V: IA32/AMD64 accel | sse3 sse2 sse mmx cmove asm [transcode] V: video buffer | 10 @ 0x0 [0x2] [transcode] A: audio buffer | 10 @ 48000x2x16 [import_ac3.so] v0.3.2 (2002-02-15) (audio) AC3 [import_null.so] v0.2.0 (2002-01-19) (video) null | (audio) null [export_ac3.so] v0.1 (2003-02-26) (video) null | (audio) ac3 [encoder.c] warning: audio codec not supported by export module [transcode] critical: failed to init export modules [transcode] critical: plug-in initialization failed +---------------- Thanks for your trouble, Andrew -- Do you think that's air you're breathing?
