When I try to run mediafilesegmenter with the following
mediafilesegmenter -iso-fragmented -z frame_index.m3u8 \
-f 720p -i index_720p \
-k key.bin -stream_encrypt -P
-K <url> \
-B seg_720p -t 6 source.mp4
I get the following output
ISO fragmented mode, forcing segments to start with I-Frame
Processing file source.mp4
track 2 of source.mp4 contains more than one valid time mapping
Unable to find any valid tracks to segment.
Segmenting failed (-15650).
What specifically should I be looking for in my MP4 that would be causing this?
