ffmpeg supports decoding and encoding of broadcast wavs (bwf format) but in my tests it strips the bext chunk from the input broadcast wav when copying it, so not outputting a valid bwf file. is this a bug or is it a configuration issue? i would be grateful for any advice.
input file has a bext chunk in aXML format output file has no bext chunk i am using bwfmetaedit (http://bwfmetaedit.sourceforge.net) to verify bext data. ffmpeg -i MAVISwithISRC.wav -acodec copy -map_metadata 0 -write_id3v2 1 -id3v2_version 3 -strict -2 out.wav ffmpeg version 2.2.1 Copyright (c) 2000-2014 the FFmpeg developers built on Apr 13 2014 13:00:18 with gcc 4.4.6 (GCC) 20120305 (Red Hat 4.4.6-4) configuration: --prefix=/usr --libdir=/usr/lib64 --shlibdir=/usr/lib64 --mandir=/usr/share/man --enable-shared --enable-runtime-cpudetect --enable-gpl --enable-version3 --enable-postproc --enable-avfilter --enable-pthreads --enable-x11grab --enable-vdpau --disable-avisynth --enable-frei0r --enable-libopencv --enable-libdc1394 --enable-libgsm --enable-libmp3lame --enable-libnut --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libopenjpeg --enable-librtmp --enable-libspeex --enable-libtheora --enable-libvorbis --enable-libvpx --enable-libx264 --enable-libxavs --enable-libxvid --extra-cflags='-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64 -mtune=generic -fPIC' --disable-stripping libavutil 52. 66.100 / 52. 66.100 libavcodec 55. 52.102 / 55. 52.102 libavformat 55. 33.100 / 55. 33.100 libavdevice 55. 10.100 / 55. 10.100 libavfilter 4. 2.100 / 4. 2.100 libswscale 2. 5.102 / 2. 5.102 libswresample 0. 18.100 / 0. 18.100 libpostproc 52. 3.100 / 52. 3.100 Guessed Channel Layout for Input Stream #0.0 : stereo Input #0, wav, from 'MAVISwithISRC.wav': Metadata: date : 2015-04-18 creation_time : 10:15:33 time_reference : 0 coding_history : A=PCM,F=44100,W=16,M=stereo,T=Sonoris ISRC Editor Duration: 00:04:48.39, bitrate: 1411 kb/s Stream #0:0: Audio: pcm_s16le ([1][0][0][0] / 0x0001), 44100 Hz, stereo, s16, 1411 kb/s Output #0, wav, to 'out.wav': Metadata: ICRD : 2015-04-18 creation_time : 10:15:33 time_reference : 0 coding_history : A=PCM,F=44100,W=16,M=stereo,T=Sonoris ISRC Editor ISFT : Lavf55.33.100 Stream #0:0: Audio: pcm_s16le ([1][0][0][0] / 0x0001), 44100 Hz, stereo, 1411 kb/s Stream mapping: Stream #0:0 -> #0:0 (copy) Press [q] to stop, [?] for help size= 49680kB time=00:04:48.39 bitrate=1411.2kbits/s video:0kB audio:49680kB subtitle:0 data:0 global headers:0kB muxing overhead 0.000197% _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user
