Hello!
I just tried out myvcd 1.4, and had the following problem:
startet by that command:
myvcd test -quality best -svcdout -sample /root/myvcd-dist/Ally.avi
I got this output:
*** MYVCD SYSTEM MESSAGE: Beginning Processing.
*** Probing /root/myvcd-dist/Ally.avi, please wait...

I know it's a little long, but maybe someone understands the problem. As I can see something's wrong with mpeg2enc. But WHY??
Thanx a lot.

I'am having problems with myvcd too. It might be something to do with my other problem.
https://forums.gentoo.org/viewtopic.php?p=753132#753132
As far as I know myvcd calls mplayer with the character "&" after it in order to perform it's other functions. |

So did you remove the ampersand (&)? Did that fix your problem?

| Removing the "&" simply stops myvcd doing encoding as it sits waiting for mplayer to stream out the video. Which it doesn't do as its waiting for something to start pulling on the stream (if thats how it works, I have little understanding of pipes and streams). |

I've just set this command going encoding a file I previously encoded using tmpeg encoder on a windows machine. It's taking an insanely long time to encode but once it is done I will compare it to the vcd made with tmpeg. The reason it is taking so long is because I have whacked up all the quality settings. |

Heres a dirty way round the myvcd problem.
Open a virtual terminal put this in it:
| Code: |
cat - < stream.yuv | yuvscaler -v 0 -M WIDE2STD -O VCD -O SIZE_352x240 -n n | mpeg2enc -4 1 -2 1 -N 1 -M 2 -r 32 -v 1 -s -f 2 -b 1152 -B 260 -V 46 -S 840 -g 6 -G 15 -F 1 -n n -4 1 -2 1 -o ./test.mpv
|
Run that and then open another virtual terminal and run this.
| Code: |
mplayer -noframedrop -vo yuv4mpeg -ao pcm -waveheader -v -osdlevel 0 "/path/to/your/video/file"
|
Run that and you should notice your first terminal window saying stuff about encoding files. Once this relatively lengthy (it's geared for very high quality as thats how I like it) process has finished run.
| Code: |
mp2enc -v 2 -b 224 -r 44100 -s -o test.mpa < audiodump.wav
|
Then run.
| Code: |
mplex -f 2 -m 1 -V -b 46 -M -O 0 test.mpv test.mpa -o test.mpg
|
After all that you should have a valid vcd mpeg that you can use vcdimager to make an image of and cdrdao to burn. Note though that the commands I gave you are not generic, they will only work for widescreen ntsc 23.97 fps source files (happened to be the one I was testing on). To make the commands work for other source files read the manpages of mpeg2enc, mplex, mp2enc, yuvscaler and make the neccessary changes to the commands. Good luck. |

Alright, I figured this one out!
Basically, mpeg2enc in mjpegtools-1.6.1+ appears to be buggy or have changed in some way that breaks compatibility with the myvcd script. I rolled it back to version 1.6.0 and the script works perfectly now! Excellent!
The line I used for rolling it back... | Code: | | CFLAGS="-O3 -march=pentium -funroll-loops" USE="-avi" emerge \<mjpegtools-1.6.1 |
I used the -avi flag to stop it trying to rollback avifile to a previous version, because the ebuild kept bombing out. I don't what effect this'll have on the script, but it appears to work with at least some files.
