I use ffmpeg to create files to be used in a broadcast system. After much digging, testing, and working with the vendor I've found that the quicktime demuxer of the broadcast server only reads the first megabyte of the stsc atom and if the stsc atom is larger than one megabyte then the audio fails to play.
Looking at QuickTime files from other tools I see that stsc is typically much smaller than 1MB. Are there any commands I could use to reduce the size of the stsc atom? At the moment if I write 55 minutes of stereo PCM audio to QuickTime than I get a >1MB stsc.
