Hi To check whether your version of FFmpeg creates m4a files that play nice with the Linn... Create some test files with different durations... 15 minutes, 30 minutes, 60 minutes etc. up to 3 hours. If they all play OK then you can eliminate FFmpeg. This is how to ceate a 15 minute (900 second) test file. ffmpeg -f lavfi -i sine=d=900 -y 900_FFmpeg.m4a =================================================== =================================================== @mint ~ $ ffmpeg -f lavfi -i sine=d=900 -y 900_FFmpeg.m4a ffmpeg version git-2017-01-21-cde007d Copyright (c) 2000-2017 the FFmpeg developers built with gcc 5.4.0 (Ubuntu 5.4.0-6ubuntu1~16.04.4) 20160609 configuration: --enable-gpl --enable-libmp3lame --enable-libvorbis --enable-libx264 libavutil 55. 43.100 / 55. 43.100 libavcodec 57. 75.100 / 57. 75.100 libavformat 57. 62.100 / 57. 62.100 libavdevice 57. 2.100 / 57. 2.100 libavfilter 6. 69.100 / 6. 69.100 libswscale 4. 3.101 / 4. 3.101 libswresample 2. 4.100 / 2. 4.100 libpostproc 54. 2.100 / 54. 2.100 Input #0, lavfi, from 'sine=d=900': Duration: N/A, start: 0.000000, bitrate: 705 kb/s Stream #0:0: Audio: pcm_s16le, 44100 Hz, mono, s16, 705 kb/s Output #0, ipod, to '900_FFmpeg.m4a': Metadata: encoder : Lavf57.62.100 Stream #0:0: Audio: aac (LC) (mp4a / 0x6134706D), 44100 Hz, mono, fltp, 69 kb/s Metadata: encoder : Lavc57.75.100 aac Stream mapping: Stream #0:0 -> #0:0 (pcm_s16le (native) -> aac (native)) Press [q] to stop, [?] for help size= 7765kB time=00:15:00.00 bitrate= 70.7kbits/s speed=51.4x video:0kB audio:7613kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: 1.999211% [aac @ 0x372b8e0] Qavg: 314.807 =================================================== =================================================== @mint ~ $ AtomicParsley 900_FFmpeg.m4a -T 1 ... ------------------------------------------------------ AtomicParsley version: 0.9.6 (utf8) ------------------------------------------------------ Movie duration: 900.024 seconds (15:0.02) - 69.29* kbp/sec bitrate (*=approximate) Low-level details.
