deinterlace generic error: doubling the frame rate ...

I'm using Ubuntu 9.10 Server and VLC 1.0.5 compiled by me + FFMPEG SVN-r19352.
I'm trying to use the deinterlace video filter for transcoding in realtime with several modes, however only discard,blend,mean,x modes work ok.
The rest of modes : bob,linear,yadif,yadif2x don't work and send the error "deinterlace generic error: doubling the frame rate is not supported yet" Segmentation fault.
How can I use bob or yadif modes to deinterlace (mabbe piping) ?
Thanks and regards

Please retry with 1.1.0.

Nope, the same problem with 1.1.0-pre1 from Git repository.
I have seen at vlc/modules/video_filter/deinterlace.c this code:
Code: Select all
case DEINTERLACE_BOB:
#if 0
RenderBob( p_vout, pp_outpic[0], p_pic, 0 );
RenderBob( p_vout, pp_outpic[1], p_pic, 1 );
break;
#endif
case DEINTERLACE_LINEAR:
#if 0
RenderLinear( p_vout, pp_outpic[0], p_pic, 0 );
RenderLinear( p_vout, pp_outpic[1], p_pic, 1 );
#endif
msg_Err( p_vout, "doubling the frame rate is not supported yet" );
picture_Release( p_pic_dst );
picture_Release( p_pic );
return NULL;
And this code is the same at versions 1.0.x, so these modes are apparently not supported yet. The code is from Sam Hocevar, the Debian leader.
Rémi, do you know if this modes are going to be activated in 1.1.0 stable ?
Thanks and regards

Frame rate doubling modes involve extra intricacies that are not resolved this far. That won't get fixed before 1.2.0 at the earliest. YADIF modes should work though.

this is still a prob with vlc 1.1.9
at the moment my source is 50fps i use 50fps as the frame rate and its doing this
main debug: looking for video blending module: 1 candidate
blend debug: chroma: YUVA -> I420
main debug: using video blending module "blend"
which im sure is for 25fps? i did try bob and yardif they just crashed my vlc on all versions i have tested none of the doubler deinterlace modes work!

1.1.x is no longer supported. Please use 2.0.
