HI I use ffmpeg to convert videos to iPod and iPad compatible. To encode I have been using: ffmpeg -i "src.avi" -y -vcodec libx264 -vpre hq -vpre ipod640 -threads 0 -vtag mp4v -b 600000 -acodec libfaac -ac 2 -ab 128000 -f mp4 -s 640x352 "src - x264.mp4" But recently( sometime in the last month or 2) this error now occurs occurs : [mp4 @ 0x198b170]Tag 0x7634706d incompatible with output codec I use gentoo and build from with an ebuild for svn.

Hi all, I cannot compile ffmpeg with libx264. I installed libx264 from compile source code. But when compiling ffmpeg, the compiler complain as below: mobiletv at mobiletv-desktop:~/Desktop/ffmpeg-0.5.2$ make gcc -L"/home/mobiletv/Desktop/ffmpeg-0.5.2"/libavdevice -L"/home/mobiletv/Desktop/ffmpeg-0.5.2"/libavformat -L"/home/mobiletv/Desktop/ffmpeg-0.5.2"/libavcodec -L"/home/mobiletv/Desktop/ffmpeg-0.5.2"/libavutil -rdynamic -export-dynamic -Wl,--warn-common -Wl,--as-needed -Wl,-rpath-link,"/home/mobiletv/Desktop/ffmpeg-0.5.2"/libpostproc -Wl,-rpath-link,"/home/mobiletv/Desktop/ffmpeg-0.5.2"/libswscale -Wl,-rpath-link,"/home/mobiletv/Desktop/ffmpeg-0.5.2"/libavfilter -Wl,-rpath-link,"/home/mobiletv/Desktop/ffmpeg-0.5.2"/libavdevice -Wl,-rpath-link,"/home/mobiletv/Desktop/ffmpeg-0.5.2"/libavformat -Wl,-rpath-link,"/home/mobiletv/Desktop/ffmpeg-0.5.2"/libavcodec -Wl,-rpath-link,"/home/mobiletv/Desktop/ffmpeg-0.5.2"/libavutil -Wl,-Bsymbolic -o ffmpeg_g ffmpeg.o cmdutils.o -lavdevice -lavformat -lavcodec -lavutil -lz -lbz2 -lm -lx264 -lm -ldl -ldl /home/mobiletv/Desktop/ffmpeg-0.5.2/libavcodec/libavcodec.so: undefined reference to `x264_encoder_open_94' collect2: ld returned 1 exit status make: *** [ffmpeg_g] Error 1 I checked function x264_encoder_open_94 as: mobiletv at mobiletv-desktop:~/Desktop/ffmpeg-0.5.2$ grep -R x264_encoder_open_94 /usr/local/lib/ Binary file /usr/local/lib/libx264.so matches Binary file /usr/local/lib/libx264.a matches Binary file /usr/local/lib/libx264.so.94 matches I don't know how to resolve this problem.
