Hi all - I had been using a patch from this mailing list on the FFMPEG source code to enable all audio tracks when encoding QuickTime MOV.
diff --git a/libavformat/movenc.c b/libavformat/movenc.c index b6821d4..136adae 100644 --- a/libavformat/movenc.c +++ b/libavformat/movenc.c @@ -2315,6 +2315,10 @@ static int mov_write_tkhd_tag(AVIOContext *pb, MOVMuxContext *mov, (version == 1) ? avio_wb32(pb, 104) : avio_wb32(pb, 92); /* size */ ffio_wfourcc(pb, "tkhd"); avio_w8(pb, version); + if (track->enc->codec_type == AVMEDIA_TYPE_AUDIO || + track->enc->codec_type == AVMEDIA_TYPE_DATA) /* enable all audio & data tracks */ + avio_wb24(pb, 0xf); + else avio_wb24(pb, flags); if (version == 1) { avio_wb64(pb, track->time); @@ -2335,7 +2339,7 @@ static int mov_write_tkhd_tag(AVIOContext *pb, MOVMuxContext *mov, avio_wb32(pb, 0); /* reserved */ avio_wb32(pb, 0); /* reserved */ avio_wb16(pb, 0); /* layer */ - avio_wb16(pb, group); /* alternate group) */ + avio_wb16(pb, 0x0); /* set alternate group 0 as default ) */ /* Volume, only for audio */ if (track->enc->codec_type == AVMEDIA_TYPE_AUDIO) avio_wb16(pb, 0x0100); However, it seems as though this no longer works as movenc has been modified since it last worked for me with source code from March 25th 2016. Is there a way to enable all audio tracks when encoding a MOV with the current source or does anyone have an updated patch?
