Description (last modified by )
Summary of the bug:
When decoding a 7h DolbyE 5.1 + 2.0 stream with the DolbyE decoder, it reaches 6h 30m and then it crashes with the following error:
"Dolby E data size 1037087 in SMPTE 337M is not implemented".
Expected result:
The decoder goes on to decode the whole stream.

How to reproduce:
Step 1:
Download the original .ts sample from here https://gofile.io/d/dGfiBO
Step 2:
Demux CH.5-6 (i.e audio track 3) to extract the DolbyE 5.1 + 2.0 track
ffmpeg.exe -hide_banner -non_pcm_mode copy -i "Isle of Wight Festival (21-6-24) (1080i) (Feed) (Dolby-E).ts" -map 0:3 -c:a pcm_s24le -f s24le -y "Isle of Wight Festival (21-6-24) (1080i) (Feed) (Dolby-E)_stream1_CH56.wav"
Step 3:
Try to decode the stream.
ffmpeg.exe -hide_banner -i "Isle of Wight Festival (21-6-24) (1080i) (Feed) (Dolby-E)_stream1_CH56.wav" -c:a pcm_s24le -ar 48000 -rf64 always -f wav -y "Isle of Wight Festival (21-6-24) (1080i) (Feed) (Dolby-E)_stream1_CH56_Decoded_51_20.wav"
and you'll see the error message after 6h 30m instead of being able to decode the whole stream.
