 Summary of the bug:
 I'm using ffmpeg to convert files to HLS format and found a file where
 audio seems to be corrupted after convertion.
 How to reproduce:
 {{{
 % ffmpeg -i https://lp-us-vod-
 com.storage.googleapis.com/directUpload/7c5a68zgc5s6gmsl -c:a copy -c:v
 copy -f hls -hls_list_size 0 -hls_playlist_type vod -hls_segment_type
 mpegts -hls_time 10 -y index.m3u8
 }}}
 {{{
 % ffprobe -loglevel warning -show_format -show_streams -print_format json
 index0.ts
 {
 [mpegts @ 0x13de04490] start time for stream 1 is not set in
 estimate_timings_from_pts
 [mpegts @ 0x13de04490] stream 1 : no TS found at start of file, duration
 not set
 [mpegts @ 0x13de04490] Could not find codec parameters for stream 1
 (Audio: aac ([15][0][0][0] / 0x000F), 0 channels): unspecified sample
 format
 Consider increasing the value for the 'analyzeduration' (0) and
 'probesize' (5000000) options
