Here are some more missing dependencies i found thanks to Mans' --enable-random option.

./configure --disable-everything --enable-encoder=amv

fails with

LD      ffmpeg_g.exe
libavcodec/libavcodec.a(utils.o): In function `avcodec_get_name':
D:\msys\1.0\home\jamal\ffmpeg/./libavcodec/codec_names.h:221: undefined reference to `ff_amv_encoder'
libavcodec/libavcodec.a(allcodecs.o): In function `avcodec_register_all':
D:\msys\1.0\home\jamal\ffmpeg/libavcodec/allcodecs.c:75: undefined reference to `ff_amv_encoder'
collect2: ld returned 1 exit status
make: *** [ffmpeg_g.exe] Error 1

The amv encoder has no entry in libavcodec/Makefile.
It uses the same files as the mjpeg encoder so it's a matter of duplicating the mjpeg entry for it:

OBJS-$(CONFIG_AMV_ENCODER)             += mjpegenc.o mjpeg.o           \
                                          mpegvideo_enc.o motion_est.o \
                                          ratecontrol.o mpeg12data.o   \

Also, like the mjpeg encoder it needs to enable aandct in the configure script:


./configure --disable-everything --enable-muxer=jacosub
./configure --disable-everything --enable-muxer=latm

Fail with

LD      ffmpeg_g.exe
libavformat/libavformat.a(jacosubenc.o):jacosubenc.c:(.data+0x34): undefined reference to `ff_raw_write_packet'
collect2: ld returned 1 exit status
make: *** [ffmpeg_g.exe] Error 1


LD      ffmpeg_g.exe
libavformat/libavformat.a(latmenc.o): In function `latm_write_packet':
D:\msys\1.0\home\jamal\ffmpeg/libavformat/latmenc.c:153: undefined reference to `ff_raw_write_packet'
collect2: ld returned 1 exit status
make: *** [ffmpeg_g.exe] Error 1

Both the latm and jacosub muxers need rawenc.c to be compiled.
On libavformat/Makefile

OBJS-$(CONFIG_JACOSUB_MUXER)             += jacosubenc.o
OBJS-$(CONFIG_LATM_MUXER)                += latmenc.o

Should be

OBJS-$(CONFIG_JACOSUB_MUXER)             += jacosubenc.o rawenc.o
OBJS-$(CONFIG_LATM_MUXER)                += latmenc.o rawenc.o

./configure --disable-everything --enable-decoder=dirac

fails with

LD      ffmpeg_g.exe
libavcodec/libavcodec.a(diracdec.o): In function `svq3_get_ue_golomb':
D:\msys\1.0\home\jamal\ffmpeg/libavcodec/golomb.h:132: undefined reference to `ff_interleaved_dirac_golomb_vlc_code'
D:\msys\1.0\home\jamal\ffmpeg/libavcodec/golomb.h:128: undefined reference to `ff_interleaved_golomb_vlc_len'
D:\msys\1.0\home\jamal\ffmpeg/libavcodec/golomb.h:135: undefined reference to `ff_interleaved_dirac_golomb_vlc_code'

D:\msys\1.0\home\jamal\ffmpeg/libavcodec/golomb.h:122: undefined reference to `ff_interleaved_ue_golomb_vlc_code'

[Another few dozen golomb errors here from different functions]

libavcodec/libavcodec.a(dwt.o): In function `ff_dwt_init':
D:\msys\1.0\home\jamal\ffmpeg/libavcodec/dwt.c:994: undefined reference to `ff_snow_inner_add_yblock'
libavcodec/libavcodec.a(dwt.o): In function `ff_spatial_idwt_init2':
D:\msys\1.0\home\jamal\ffmpeg/libavcodec/dwt.c:1504: undefined referenceto `ff_spatial_idwt_init_mmx'
libavcodec/libavcodec.a(dwt.o): In function `ff_dwt_init':
D:\msys\1.0\home\jamal\ffmpeg/libavcodec/dwt.c:997: undefined reference to `ff_dwt_init_x86'

This shows that the Dirac decoder depends on dwt and golomb, and that dwt needs snow.c

dirac_decoder_select="dwt golomb"

To the configure script, and making

OBJS-$(CONFIG_DWT)                     += dwt.o


OBJS-$(CONFIG_DWT)                     += dwt.o snow.o

in libavcodec/Makefile fixes this.

Also, you can remove dwt.o from the dirac decoder dependencies in libavcodec/Makefile now that dwt will be enabled with the configure addition.

./configure --disable-everything --enable-decoder=iac

fails with

LD      ffmpeg_g.exe
libavcodec/libavcodec.a(imc.o): In function `imc_decode_close':
D:\msys\1.0\home\jamal\ffmpeg/libavcodec/imc.c:933: undefined reference to `ff_fft_end'
libavcodec/libavcodec.a(imc.o): In function `imc_decode_init':
D:\msys\1.0\home\jamal\ffmpeg/libavcodec/imc.c:140: undefined reference to `ff_sine_window_init'
D:\msys\1.0\home\jamal\ffmpeg/libavcodec/imc.c:188: undefined reference to `ff_fft_init'
collect2: ld returned 1 exit status
make: *** [ffmpeg_g.exe] Error 1

This is the new Indeo Audio decoder added a few days ago. It simply needs a line in the configure script:

iac_decoder_select="fft mdct sinewin"

Which is a copy of the imc decoder one, given that both share the same functions.
I'm not sure why mdct is in there, though, since it doesn't seem to be used by these decoders.

Sorry for taking a few days reporting these, since now they wont make it to ffmpeg 0.11.1
I had this ready but got sidetracked with the dirac crash from the other ticket.

  • Resolution set to fixed
  • Status changed from new to closed

All issues should be fixed, iac works fine here with only "sinewin" enabled.

Thank you for the report!
