How Can I extract mp4 from http live streaming m3u8 file? I Tried this command below:
ffmpeg -i {input file} -f rawvideo -bsf h264_mp4toannexb -vcodec copy out.mp4
I took this error:
[NULL @ 0000000002f07060] Packet header is not contained in global extradata, corrupted stream or invalid MP4/AVCC bitstream Failed to open bitstream filter h264_mp4toannexb for stream 0 with codec copy: I

Your command is completely incorrect. The output format is not rawvideo and you don't need the bitstream filter h264_mp4toannexb which is used when you want to convert the h264 contained in an mp4 to the Annex B format used by MPEG-TS for example. What you want to use instead is the aac_adtstoasc for the AAC streams.
ffmpeg -i http://.../playlist.m3u8 -c copy -bsf:a aac_adtstoasc output.mp4

Aergistal's answer works, but I found that converting to mp4 can make some m3u8 videos broken. If you are stuck with this problem, try to convert them to mkv, and convert them to mp4 later.
