Hi, I get this error:
When trying to decrypt with ffmpeg -i video.mp4 -decryption_key 000:000Code:[mov,mp4,m4a,3gp,3g2,mj2 @ 0x731f900] multiple fourcc not supported Last message repeated 3 times [mov,mp4,m4a,3gp,3g2,mj2 @ 0x731f900] Could not find codec parameters for stream 0 (Video: h264 (avc1 / 0x31637661), none, 426x240): unspecified pixel format Consider increasing the value for the 'analyzeduration' (100000000) and 'probesize' (100000000) options
Is there a way to convert or encode the file before to decrypt ??
Any suggestion to decrypt the mp4?
With mp4decrypt I can get it works but this is slow and load my cpu up.
Thanks in advance

You've basically answered your question yourself. If mp4decrypt works: use mp4decrypt to decrypt the video. It's a one time operation. If it's too slow for you: use a computer with a faster CPU.

When I use mp4decrypt and then remux the segments with ffmpeg the output freeze every 30 seconds.
This is the ffmpeg command to remux the audio and video decrypted files:
ffmpeg -y -v error -hide_banner -nostats -re -i video.mp4 audio.m4a -c copy -hls_flags delete_segments -hls_time 4 -hls_list_size 10 index.m3u8
