mp4hls ignoring DRM signaling #543

Open qchroman opened 4 years ago

qchroman commented 4 years ago

Hello all,

I have noticed that if you run the following command 

python.exe ./mp4-hls.py -f ^
--... ^
--widevine ^
--fairplay ^
--output-dir=./output/hls-fp-wv ^
./input/sintel_trailer-480p.frag.mp4 ./input/sintel_trailer-720p.frag.mp4

To add FP and WV to the HLS output, the output is missing the WV signaling inside the iframe.m3u8 manifest

#EXTM3U
#EXT-X-VERSION:5
#EXT-X-PLAYLIST-TYPE:VOD
#EXT-X-I-FRAMES-ONLY
#EXT-X-INDEPENDENT-SEGMENTS

#EXT-X-MEDIA-SEQUENCE:0

#EXTINF:24.541667,
#EXT-X-BYTERANGE:16920@376

#EXT-X-ENDLIST

And the stream.m3u8 is missing the FP signaling

Tested with 1.6.0-637 version of Bento.

Indeed, the iframes playlist is missing the KEY entry for Widevine. But in a simple test on my system, I can verify that the stream.m3u8 playlist does contain both KEY lines. Ex:

mp4hls -f "--widevine=#CAESEFrhmIc9xxxlIzazFsP2hbCAcKgJIRA==" --fairplay=uri:skd://0fda16c25ae198873dd948cdacc5b01c --encryption-key=00112233445566778899aabbccddeeff000102030405060708090a0b0c0d0e0f video.mp4

Gives:

#EXTM3U

#EXT-X-INDEPENDENT-SEGMENTS
#EXT-X-TARGETDURATION:6
#EXT-X-MEDIA-SEQUENCE:0

I apologize for not using the command right in my initial report, I completely ignored the widevine header value and the fairplay URI value.

Here are my latest tests

python ./1.6.0.637/utils/mp4-hls.py -f ^
--widevine=#CAESEKHfoShqOEkwkq6uVMR7B2MaC2J1eWRybWtleW9zIhCh36EoajhJMJKurlTEewdjKgJIRA== ^

--output-dir=./output/dash-hls-wv-issue ^
./input/sintel_trailer-480p.frag.mp4 ./input/sintel_trailer-720p.frag.mp4

results in the following:
