I am able to play m4a files up to 30 minutes duration when muxed with mp4creator program. Create a 30 minute "raw aac" test file with FFmpeg... ffmpeg -f lavfi -i sine=d=1800 -y 1800_testfile.aac Mux it into m4a with mp4creator... mp4creator -create=1800_testfile.aac 1800_testfile.m4a See if it plays OK. mp4creator is here ---> https://sourceforge.net/projects/mp4creator/files/mp4creator/version%201.6.1e-pre/ It works with Linux and Wine too... ~ $ wine ./mp4creator.exe -version Z:\home\user\mp4creator.exe - mpeg4ip version 1.6.1e-pre _______________________________________________ get_iplayer mailing list [email protected] http://lists.infradead.org/mailman/listinfo/get_iplayer
