0001592: PAL 4:3 VOB 2 pass Error: Unable to parse option value "dv_pal": undefined constant or missing (

Notes
(0005149) espinosa_cz (reporter) 2010-05-19 00:08	Same problem here :( Unable to parse option value "dv_pal": undefined constant or missing ( Last message repeated 1 times AC EOB marker is absent pos=71 AC EOB marker is absent pos=64 Kdenlive Profile "PAL 4:3 VOB 1 pass" from a Raw DV files project. Mandriva 2010, Kdenlive 0.7.7

(0005150) espinosa_cz (reporter) 2010-05-19 01:48	When option 'profile=dv_pal' is removed it crashes with this exception on the roughly same place: Rendering of /home/espinosa/kdenliveworkspace/render/foo.vob crashed AC EOB marker is absent pos=64 Last message repeated 1 times AC EOB marker is absent pos=65 AC EOB marker is absent pos=64 Last message repeated 13 times AC EOB marker is absent pos=71 AC EOB marker is absent pos=66 AC EOB marker is absent pos=64 Last message repeated 11 times AC EOB marker is absent pos=93 AC EOB marker is absent pos=64 AC EOB marker is absent pos=68 AC EOB marker is absent pos=64 Last message repeated 3 times AC EOB marker is absent pos=67 AC EOB marker is absent pos=64 Last message repeated 1 times AC EOB marker is absent pos=66 AC EOB marker is absent pos=64 ..so this is a ffmpeg raw DV encoding issue

(0005151) espinosa_cz (reporter) 2010-05-19 01:50	And I also tried to play with 'error resilience' parameter to ffmpeg but with to no effect: f=dvd vcodec=mpeg2video acodec=ac3 b=5000k maxrate=8000k minrate=0 bufsize=1835008 mux_packet_s=2048 mux_rate=10080000 ab=192k ar=48000 s=720x576 g=15 me_range=63 trellis=1 er=0 I tried er=0, er=4, er=1 (default) - no difference

(0005235) Espinosa (reporter) 2010-05-29 21:27	OK, confirmed, this is not a Kdenlive or MLT bug. This is caused by old ffmpeg version in your distribution. Last stable release of Ffmpeg 5.0 (=libavcoded 5.2 ??) is simply too old :( but many distributions are reluctant to ship svn based ffmpeg versions. You have to build ffmpeg from svn (and ideally mlt and kdenlive too). I did today and now I am able to render the affected part without problems. See: http://lists.mplayerhq.hu/pipermail/ffmpeg-user/2007-July/010125.html [^] ..strange, it is reported as fixed in July 2007 and the fix did not get to the 5.0 final!?!?! Or 5.0 release is really sooo old? Or they have a regression unfortunately in the same time when distributions prepare their versions. @Administrator: you can mark this issue as not relevant to kdenlive/mlt. However there is still a minor cosmetic bug in MLT profile, the "dv_pal": undefined constant - the dv_pal option is somewhat incorrect in newer (?) ffmpeg versions but it is harmless message appearing only when something ELSE fails. Please fix the profile.
