Well, In case someone is interested in the problem, the files are here: http://delio.homelinux.com/mjpeg/ teste.m2v is 3.2MB and teste.mpg is 3.5MB
---------- Original Message ---------- Date: Wednesday 15 November 2006 16:02 Well, it's a problem hard to describe and hard to believe. Where it all began: 1) Capturing in kino from (old) VHS tape. VHS -> composite video/audio -> DV Camcorder -> firewire -> kino 2) Sliced out unwanted material (beginning and ending of tape, etc) and saved as smil. Size is 0:40:46.177 3) Encoded the above generated smil, like this: smil2yuv $1.smil | mpeg2enc -H -v 0 -n n -I 1 -a 2 -b $2 -f 8 -q 4 -4 1 -2 1 -r 32 -g 6 -G 18 -B 260 -K tmpgenc -o vid_$1.m2v > log1_$1.txt 2> log2_$1.txt smil2wav $1.smil | mp2enc -e -o aud_$1.mp2 >> log1_$1.txt 2>> log2_$1.txt mplex -f 8 -R -V -o $1.mpg vid_$1.m2v aud_$1.mp2 >> log1_$1.txt 2>> log2_$1.txt 4) Opened in qdvdauthor, but size was only 0:32:28 (I think my qdvdauthor uses mplayer). 5) Opened mpg in xine, same result. Opened in kino, by importing the mpg file, same result (32 min). ******************************* * long long long time testing * ******************************* I decided to slice the dv file to only 170 frames to do the tests, of course. The only hint I have came from importing the mpg file to kino. It uses mencoder and ffmpeg to convert mpg to dv, so I picked up his script and joined after encoding, like this: ============================== cat teste.smil smil2yuv teste.smil | mpeg2enc -H -f 8 -o teste.m2v smil2wav teste.smil | mp2enc -e -o teste.mp2 mplex -f 8 -R -V -o teste.mpg teste.m2v teste.mp2 mencoder -o /home/delio/teste.mpg.avi -oac pcm -ovc lavc /home/delio/teste.mpg lavinfo teste.mpg.avi ============================== results of this script is attached as mpeg_script_results.txt ============================== During mencoder run, this is what happens: ... 1 duplicate frame(s)! Pos: 0.7s 22f ( 9%) 0fps Trem: 0min 3mb A-V:0.070 [0:1536] Skipping frame! Pos: 1.5s 47f ( 9%) 0fps Trem: 0min 3mb A-V:0.067 [60:1536] Skipping frame! Pos: 5.6s 170f (100%) 51fps Trem: 0min 2mb A-V:0.016 [1811:1536] Flushing video frames ... Out of lavinfo (that should be 170 frames): ... video_frames=167 ... 6) More information when importing files to kino: Importing file teste.mpg results in 166 frames Importing intermediate video file teste.m2v results in 168 frames 7) After much of testing, one last tool in my system: Avidemux! 8) Opened in Avidemux, great! 0:40:46.179 ! The question is: What is wrong? It seems xine and mplayer can not deal with this mpeg stream. Is it some kind of outdated libs? ************************************ * Information: System and Versions * ************************************ model name : AMD Athlon(TM) XP1800+ stepping : 2 cpu MHz : 1544.717 cache size : 256 KB Main memory: 256 MB DDR OS (Fedora Core 4): 2.6.17-1.2142_FC4 mjpegtools: 1.9.0 (2.2.6) xine: v0.99.4. mencoder: 1.0pre7-4.0.2 dvdauthor: version 0.6.11. qdvdauthor: 0.1.0 avidemux: 2.1.2 ------------------------------------------------------- ------------------------------------------------------------------------- Take Surveys.
