Re: I downloaded NF videos in HD, I can play off line,need a little help W/.key file


I don't think it's the crypt0.key. When it says invalid data found when processing input I think it means this.

If you look at the sample with a hexeditor, you will see it starts
with 65536 characters that are not part of the video stream
(nearly all of them are "0").

You can either cut them away with (for example)
dd if=001ST_4Q_MA4_HC_11_L1.264 of=test.264 bs=65536 skip=1
or force ffmpeg to read a h264 stream:
ffmpeg -f h264 -i 001ST_4Q_MA4_HC_11_L1.264

It could be argued that FFmpeg should search harder for the begin
of a usable stream but there will always be a file that has more
trash at the begin and for some inputs, it is very undesirable
to initially read a lot of data.
This could be the answer to my problem but, I don't understand any of what it means. Would someone please help by clarifying these instuctions for me?
