 Summary of the bug:

 As stated above, attempting to generate encrypted HLS segments in the fmp4
 format results in a segfault.


 How to reproduce:

 Take the sample snippet below, which generates encrypted HLS variants of
 the format fmp4:

 {{{
 /home/lin/bin/ffmpeg -stream_loop -1 -loglevel debug -threads 4 \
 -init_hw_device cuda=cuda -hwaccel cuda -filter_hw_device cuda \
 -filter_complex_threads 4 -vsync 1 -i '/home/lin/Desktop/src/sowdtow.webm'
 -filter_complex \
 "['v:0']split=2[s0][s1]; \
 [s0]hwupload,scale_npp=w=1920:h=1080:interp_algo=lanczos:format=yuv420p[v0];
 \
 [s1]hwupload,scale_npp=w=1280:h=720:interp_algo=lanczos:format=yuv420p[v1]"
 \

 /home/lin/Desktop/src/test.keyinfo \
 "/home/lin/Desktop/dest/vs%v/manifest.m3u8"
 }}}

 Now comes the console output:
