I don't know.
Actually, the OSGF library attempts to support older versions:
#if LIBAVFORMAT_VERSION_INT < AV_VERSION_INT(52, 100, 0)
if (url_fopen(&oc->pb, filename, URL_WRONLY) < 0) {
#else
if (avio_open(&oc->pb, filename, AVIO_FLAG_WRITE) < 0) {
#endif
So it will use the old API for versions of libavformat prior to
52.100.0.
Presumably that version number should be higher; your error message
suggest that you're using a newer version but which doesn't define the
newer macro.
I have no idea how the package versions (e.g. 5:0.7.15-dmo1)
correspond to ffmpeg's internal version numbers. E.g. here I have
ffmpeg-0.10.3, which has:
Library Version Defined in header
libavutil 51.35.100 libavutil/avutil.h
libavformat 53.32.100 libavformat/version.h
libavcodec 53.61.100 libavcodec/version.h
libavdevice 53.4.100 libavdevice/avdevice.h
libavfilter 2.61.100 libavfilter/version.h
