'''key benefits / fields of application:''' (1) Exporting first frame of each scene as an image effectively creates generates a storyboard ... (2) ... which in turn would be an enormous help in identifying added and deleted scenes when comparing the content of two videos. (3) Alternatively, when storing the timestamps in a text file, this text file could then be fed to a video editor to automatically split a long recording into individual scenes. (4) Using I-frame upon scene change for improving compression ratio.

#1404(avcodec:new): Several problems with prores decoders/encoders during compilation

#1404: Several problems with prores decoders/encoders during compilation ---------------------------------+-------------------------------------- Reporter: jamal | Type: defect Status: new | Priority: normal Component: avcodec | Version: git-master Keywords: prores | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | ---------------------------------+-------------------------------------- Some problems i found with the different prores decoders and encoders. First, the following configuration fails when linking the executables: {{{ ./configure --disable-everything --enable-decoder=prores }}} The error is as follows: {{{ LD ffmpeg_g.exe libavcodec/libavcodec.a(proresdec2.o): In function `decode_init': D:\msys\1.0\home\jamal\ffmpeg/libavcodec/proresdec2.c:73: undefined reference to `ff_proresdsp_init' collect2: ld returned 1 exit status make: *** [ffmpeg_g.exe] Error 1 }}} The problem is that libavcodec/Makefile is not compiling proresdsp.c when this decoder is enabled alone. {{{ OBJS-$(CONFIG_PRORES_DECODER) += proresdec2.o }}} should be {{{ OBJS-$(CONFIG_PRORES_DECODER) += proresdec2.o proresdsp.o }}} ---- Second, when for example configuring with {{{ ./configure --disable-decoders --enable-decoder=prores_lgpl }}} The compilation succeeds, but both ffmpeg and ffprobe crash when trying to read a file with a prores stream. The problem is that proresdsp.c contains two functions used by the prores_lgpl decoder that only consider "CONFIG_PRORES_DECODER" but not "CONFIG_PRORES_LGPL_DECODER" during compilation. In both cases {{{ #if CONFIG_PRORES_DECODER }}} should be {{{ #if CONFIG_PRORES_DECODER | CONFIG_PRORES_LGPL_DECODER }}} Since the other prores decoder also uses these functions. ---- Third, when compiling for example with {{{ ./configure --disable-encoders --enable-encoder=prores_kostya }}} The compilation succeeds as well, but ffmpeg crashes when trying to encode using said encoder. The problem is once again in proresdsp.c where two functions needed by the prores_kostya encoder checks for CONFIG_PRORES_ENCODER when it should check for CONFIG_PRORES_KOSTYA_ENCODER instead. In both cases {{{ #if CONFIG_PRORES_ENCODER }}} should be {{{ #if CONFIG_PRORES_KOSTYA_ENCODER }}} Since the other prores encoder doesn't use functions from proresdsp.c at all. ---- I presume most of these problem were introduced after the decoders/encoders got a name change in one of the merges from libav. The prores and prores_anatoliy encoders are exactly the same thing for example, yet for some reason are two separate encoders. Once again, found this thanks to Måns' --enable-random feature. -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/1404> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker
