Invalid data when converting mp4 to x264 with ffmpeg but fine when converting flv to x264

15 octobre 2018, par Julien

I have a PHP script that converts uploaded videos to x264, it works fine if I upload an FLV, but with an MP4 it doesn’t work, here’s the command and output :

Command :

ffmpeg -y -i ../../flv/rjaRGKzSMtksUJ4kGbsLMYEcr.mp4 -crf 0 -vcodec libx264 -movflags faststart ../../flv/rjaRGKzSMtksUJ4kGbsLMYEcr.mp4 2>&1

As you can see there are some errors, there. I’ve tried with several different mp4 files, from different sources so it’s not a problem of the video files.

I’ve also tried without the -movflags faststart option, also tried with -q:v 0 instead of -crf 0, nothing works, but like stated above, it works from FLV -> MP4, what am i doing wrong here ?

PS : By "Nothing works" I mean the resulting MP4 plays for 1 frame in the browser and stops.

Why this shell command doesn't work ? ('command' works but 'command|cat' doesn't work)

16 octobre 2018, par yabee

Problem

The following code outputs like...

$ ffprobe -show_frames -select_streams v test.mp4 2>/dev/null|grep -A 2 key_frame=1

key_frame=1

pkt_pts=0

pkt_pts_time=0:00:00.000000

--

key_frame=1

pkt_pts=41041

pkt_pts_time=0:00:01.710042

--

key_frame=1

pkt_pts=64064

pkt_pts_time=0:00:02.669333

--

key_frame=1

pkt_pts=87087

pkt_pts_time=0:00:03.628625

--

...

But the folowing one outputs nothing.

$ ffprobe -show_frames -select_streams v test.mp4 2>/dev/null|grep -A 2 key_frame=1|cat

And...

$ ffprobe -show_frames -select_streams v test.mp4 2>/dev/null|grep key_frame=1

key_frame=1

key_frame=1

key_frame=1

key_frame=1

$ ffprobe -show_frames -select_streams v test.mp4 2>/dev/null|grep key_frame=1|cat

# Nothing outputted.

Why ?

Expected result

What actually I want to do is

$ ffprobe -show_frames -select_streams v test.mp4 2>/dev/null|grep -A 2key_frame=1|grep time

pkt_pts_time=0:00:00.000000

pkt_pts_time=0:00:01.710042

pkt_pts_time=0:00:02.669333

pkt_pts_time=0:00:03.628625

...

But its result is

$ ffprobe -show_frames -select_streams v test.mp4 2>/dev/null|grep -A 2key_frame=1|grep time

# Nothing outputted.

Grep works correctory exept it’s after ffprobe.

$ seq 30|grep 1|grep 2

usage: ffprobe [OPTIONS] [INPUT_FILE]



You have to specify one input file.

Use -h to get full help or, even better, run 'man ffprobe'.

What is problem ?

Does grep or ffprobe change its behavior by existence of pipe in this case ?
Thanks.
