 |

When I try to use transcode, I get an error message, it can not find codecs: mp4a avc1: | Code: | transcode -i sany0002_1.mp4 -M1 -y ffmpeg --export_prof dvd-ntsc --export_asr 2 -o movie -D0 -m movie.ac3 -J modfps=clonetype=4 --export_fps 29.97

[codecs] Warning: quicktime_decode_audio_stub called
[codecs] Warning: Could not find video Decoder for fourcc avc1

Which package contains these codecs?
Transcode don't have them nor mplayer:

mp4a means audio in an mp4 container, which is most likely aac
avc1 is h.264 video
so enable aac and x264 useflags, and you should be okay
i'd also recommend upgrading to the latest ~arch versions of ffmpeg (0.5) and transcode (1.1.2), while you're at it

I've added these two flags: aac x264 to make.conf upgraded to new ~arch transcode-1.1.2 | Code: | | media-video/transcode-1.1.2 USE="X a52 aac alsa dv dvd iconv jpeg mmx mp3 ogg quicktime sdl sse sse2 truetype vorbis x264 xml xvid -3dnow (-altivec) -imagemagick -lzo -mjpeg -nuv -oss -postproc -theora -v4l2" |
but transcode still fails with: | Code: | transcode -i sany0002_1.mp4 -M1 -y ffmpeg --export_prof dvd-ntsc --export_asr 2 -o movie -D0 -m movie.ac3 -J modfps=clonetype=4 --export_fps 29.97

tovid encountered an error during encoding:
There was a problem with encoding the audio to ac3 format.

Sorry for the inconvenience!

Transcode is enabled with acc and x264 but now it fails only on "x264" with
warning: quicktime codec 'avc1' not supported for RGB!
is it the reason transcode does not work? |

trying to use "transcode" or "tovid" to convert MPEG-4 to MPEG-2 doesn't work
but using "mencoder" works.
Information from:
http://www.linux.com/articles/53702 | Code: | | mencoder -oac lavc -ovc lavc -of mpeg -mpegopts format=dvd -vf scale=720:480,harddup -srate 48000 -af lavcresample=48000 -lavcopts vcodec=mpeg2video:vrc_buf_size=1835:vrc_maxrate=9800:vbitrate=5000:keyint=18:aspect=16/9:acodec=ac3:abitrate=192 -ofps 30000/1001 -o video_OUT.mpg video-IN.mp4 |
However, doesn't matter what package I use I always get errors: "...AVC: Consumed only x bytes instead of ..."
| Code: | ...
[h264 @ 0x12c83a0]AVC: Consumed only 23423 bytes instead of 23428[1909:224]
[h264 @ 0x12c83a0]AVC: Consumed only 25093 bytes instead of 25100[1909:224]
... |
is this a problem with x264 compatibility? |
