 |
|
I've in the middle of copying my movie collection onto hard disk, and on some movies something goes wrong while encoding/decoding the video. When playing the files, around halfway through the movie the image goes crazy and I get the following in xterm:
mplayer:
[h264 @ 0xc4f520]warning: first frame is no keyframe

....etc
has anyone got any idea whats going on? is it something wrong with the encoding or decoding?

| When was the last time you updated x264-svn? If not recently, I would recommend trying that to rule out a decoding issue (the svn-ebuild is the only one in Portage, and it's reasonably stable anyway, never had any issues with it). |

And I can't encode with the newest version:
Movie-Aspect is 1.78:1 - prescaling to correct movie aspect.
[swscaler @ 0xb95480]SwScaler: using unscaled yuv420p -> yuv420p special converter
x264 [error]: width or height not divisible by 2 (576x1)
x264_encoder_open failed.
FATAL: Cannot initialize video driver.

Do you have x264-svn and x264-svn-encoder installed? They separated the enconding/decoding libraries into two ebuilds. |

I'm using mencoder, which just has a dependancy on the .so library (which x264-svn provides...)

Regardless of what it _says_ the dependencies are, have you tried installing x264-svn-encoder? Otherwise, I'm not sure how mencoder is going to encode something in a format that it doesn't have the encoder for... |

x264-svn-encoder has a program that does stand-alone programming. It links against the library in x264-svn that mencoder also links against, that both mencoder and x264 (program) use to encode stuff. I've had a look, and the x264 program takes raw input - since I'm encoding dvds, the size of the raw input would be prohibitively large...

That's strange... I've been using transcode to encode DVDs into H264 with ffmpeg, but it doesn't work without x264-svn-encoder installed (complains about being unable to load a library). I thought that mplayer used ffmpeg where available? Or am I thinking of something else?
In any case, with reference to the original problem, it sounds like the original files weren't encoded correctly, if the latest x264-svn doesn't play them. |

I've got a similar problem with the newest version 20070325 (masked ~x86), which worked fine on the first DVD I tried encoding, but not the second one so far:
[swscaler @ 0x8600508]SwScaler: BICUBIC scaler, from yuv420p to yuv420p using MMX2
[swscaler @ 0x8600508]SwScaler: using 4-tap MMX scaler for horizontal luminance scaling
[swscaler @ 0x8600508]SwScaler: using 4-tap MMX scaler for horizontal chrominance scaling
[swscaler @ 0x8600508]SwScaler: using n-tap MMX scaler for vertical scaling (YV12 like)
[swscaler @ 0x8600508]SwScaler: 720x480 -> 752x320
x264 [error]: width or height not divisible by 2 (320x1)
I don't really know what to tell you about the other problem though, just to say that you're not alone in problems with the newer driver. |
