Additionally ffmpeg3.4+ failed to decode some mp4a samples, because internal decoder state was not reset after 'gaps' in the audio-stream. These gaps may be caused by network transmission errors. This got fixed with 56aee28f1edf686abaefd31f295130bebd2c9cf1.

Tip When using ffmpeg you can avoid corrupt files by using -f mpegts. This will create .ts instead of .mp4. It also allows you to watch the stream while downloading. Later you can use ffmpeg -i file.ts -c copy file.mp4.

These fixes refer to the untrunc program itself. You have to use untrunc as described here
