Everywhere (for me) is defined as: Samsung Galaxy S3 - to S7 (Android
4+), Chromebook (preferably), iPhone (4S)+, iPad 2+ (Apple iOS),
MacBook (Mac OS X), Windows 7+ (10), and Debian Linux. (Windows XP
also needed, and it works with 3rd party codecs).
What you want is out of control of the encoders. When players refuse to support 
a standard then there is nothing the encoders can do about it.


Most people skip right past the default players and install VLC. VLC runs on all 
the platforms you've mentioned (and more). It supports the latest and best video 
& audio standards, comes with the same user interface and nobody needs to make 
any compromises with regards to quality or versatility (except for having to 
install it). It's been the perfect solution to this problem and the reason for 
its popularity, but it's also likely not the solution you were expecting to find.

so what is the problem of ffmpeg? guess what - you are supposed to use

Encode any file into *.mov and try to play it. Either from Samsung
File Manager or Samsung Video Player or from Android Gallery. (tested
on Samsung Galaxy S7, but I'm pretty sure same will happen on every
other Galaxy; If you need I can also test on Galaxy S3 and Galaxy Note
10.1 tablet and Galaxy Tab S2 tablet, which I also have in my family)

*But* if you change the file extension of the encoded *.MOV file to
*.mp4, it plays perfectly with both players.
Moreover, the Android video file scanner refuses to detect and to add
MOV files to the video library (which works great for WebM and MP4
files).
What happens is that Android refuses to recognize MOV as a video file.
(until you install VLC for Android or some 3rd party video player)

Basically MP4 and MPEG-4-AVC, being a standard, gives some advantages.

Yes, I read this table and I consider it a good job. But it doesn't
mention "timebase" and not a pee about "-video_track_timescale"
parameter.
Perhaps this info should be added.

What I see is that iPhone 4S (and above) as well as iPad 2+ are fairly
good. They can decode H.264 Full HD 1080p video @ 30 fps (8-bit)
perfectly. Because I require Full HD 1080p videos, older devices like
iPhone 1 or iPad 1 can't play those, and are unsupported by Apple
anyway, they can be removed from "compatible 1.0" profile.

Yeah, maybe.
But I don't know how-to write a wrapper around ffmpeg. Can I extract
information like timebase and fps and duration from input video file ?

Best wishes,

Wow, you're opening a can of worms in a world of incompatibility. Have
you seen this (perhaps outdated, perhaps slightly incorrect) table,
just for iOS?
https://trac.ffmpeg.org/wiki/Encode/H.264#iOS
(Other sources for this information can also be found.)

And then check for websites which recommend how to encode for the web
for compatibility with iOS AND other mobile devices AND desktop, and tell you 
how
many variants of your video you need to provide, for "sufficient"
coverage. (Perhaps those days are over since a few years? Dunno.)

With iOS obsoleting itself every few years, few << 5. ;) (May be
exaggerated, I don't have enough data.)

I think you're deep into "wrapper" land, which needs to maintain
knowledge (and requirements like yours) outside of an encoder.

Just my $0.02,
Moritz

Are you sure it's checking the static library you just built (and
installed to /home/torstein/mpv-build/build_libs)?

Anyway, looks like an mpv problem to me.

Let's call my wish " -compatible 1.0" (targeting current-gen hardware)

[FFmpeg-user] Tee muxer and rtmp parameters

[Reuben Martin]

I’m trying send rtmp connections to 2 separate destinations using the tee
muxer, but I haven’t been able to find a way to set rtmp_conn values
separately for each rtmp slave. Is this even possible using the tee muxer?

I’m currently using 3.1.4. (can build head of master if that makes any
difference)

This is the second comment today that could be misinterpreted:
Please remember that not everybody is a native speaker and
be more careful.

Allow me a question:
Did you test with any non-QT based player?
If your analysis were right, nothing could play the sample, so I
believe it is safe to say that your analysis cannot be correct.

You are of course right that isom is based on mov but you
are missing two (important) things:
There is a difference between mov and isom.
Alexey told us that he needs QT compatibility but he told
FFmpeg that he absolutely doesn't care about QT, he
requested an isom file (and that's why FFmpeg did not try
to create a QT-compatible file and did not warn that the file
is not QT-compatible).

The mdhd atom in the file is version 1 and has 64bit time and
duration fields and is therefore twelve bytes larger than a
version 0 mdhd atom.

Thank you for finally solving the question why QT fails!

The fact that these files don't work with one of the world's most popular 
players is a problem.
You can argue about whether it's a bug or not, but at some point no user is 
going to sit there happily not watching a video, thinking "aren't ffmpeg's 
developers experts."
Priority one is that things work. All else is secondary.

Upon closer inspection, there is definitely a problem. The 1000 you are
referring to is in the wrong place in the video track's mdhd atom. mdhd
should be 32 bytes, according to the Apple specification for QuickTime,
which the MP4 file format is based upon. The mdhd in Alexey's file is 44
bytes. mdhd should look like this:

[] //size
[] //'mdhd'
[0]//version
[000]  //flags
[] //creation time
[] //modification time
[] //time scale
[] //duration
[00]   //language
[00]   //quality

The mdhd atom in question is located at offset 12065154
in BrokenVideo-8min.mp4. The 1000 is actually where language and
quality should be, and spans both fields. Then there's an extra 12 bytes at
the end of the atom.

I double checked this with a properly encoded MP4 file, and sure enough
mdhd for the video track was 32 bytes.

Just look at mdhd and you'll see what I'm talking about.

ffmpeg -r 25 -i  -af=atune=25/24  

Just a heads-up: on a test clip, looks like using -ss and -r before -i
causes frame-sync issues, so if you were wanting to skip forward into your
test clip, make sure to use -ss after -i .

Now, can you look at the command which is to generate a video with blend

Only one line is printed to stdout.
An alternative is to use -loglevel warning or error or fatal.

[FFmpeg-user] essence MD5

[Ganesh.Irelan]

Hello,

Non-developer here...

I want to generate an essence MD5 for WAV files and then populate that value 
into a field in a DAM system.  I have tested two commands to generate the 
essence MD5 hash.

ffmpeg -i INPUT -map 0:a -f md5 OUTPUT.md5
ffmpeg -i "INPUT" -map 0:a -f md5 -hash md5 -

Neither of these is ideal.  The first one puts the value in a separate file.  
The second puts it amongst other info in the console making it difficult to 
parse out as in the following example.  (The value I want is the fourth line 
from the bottom.)  Is there an FFMPEG command that will give a cleaner console 
output than this?

Thank you,
Kevin

Iiuc, mpv uses libavformat to demux isom (but I didn't mention
FFmpeg above), I used the old MPlayer mov demuxer for testing.

Why isn't ffmpeg being used to just fix the broken files in Alex's collection?

According to him is it 3 videos out of 700, which have this issue. Why can't 
these be fixed?

Then use the setpts filter, the input option -r tends to be unreliable.
Although using setpts means you have to take care if audio and
video start at the same time.

Or to say it differently: setpts is recommended, if r works for you,
all the better!

Since you change the video length, you have to change audio
speed, I don't know if asetpts is an alternative to atempo.

Re: [FFmpeg-user] Why FFmpeg provides it's own decoder, but relies on 3rd party encoders?

Everything?
Like mpeg2video, mpeg4 asp, msmpeg4, mp2, ac-3, e-ac-3 and
hundreds more?

External decoders like libopenjpeg exist though.

> Why so ?

lame is older than FFmpeg, libvpx was written by a company to
support their video format (it wouldn't have made sense for them
to implement an FFmpeg-based encoder) and x265 is a direct
successor of x264.

At the time x264 was started, FFmpeg still tried to implement all
encoders themselves (and the saying was "first write a working
encoder, then start with the decoder implementation").
There is a very old post somewhere that explains why x264 was
written as an independent project, in retrospect this was a large
advantage for the single developers.

The main reason is that nobody sent patches for the mentioned
encoders so far...

I believe it is possible to write a (not top-quality) mp3 encoder on
top of FFmpeg (just needs a bitstream filter), but nobody cared.

Thanks for your response Carl Eugen,.

Up until now i only had to deal with image sequences and didn't
convert them myself. Therefore i wasn't sure if the results could
have been better with other options. Thanks for your feedback.

This is old and unsupported, if you don't want to compile yourself,
you can download a binaries that other users provide from external
sites linked from our download page:
http://ffmpeg.org/download.html

> Not all the images I use have the same resolution, can FFmpeg

It will automatically scale them to the output resolution (that defaults to
the resolution of the first input frame).

[FFmpeg-user] Create a video using images and audio with blend and zoom filters using FFmpeg

[Nikhil M Ranka]

Note: I have a few days ( 3-4 ) of experience with using FFmpeg, and I do
not fully understand the commands I mention here ( most of them are from
stack overflow forums - I do not have those links bookmarked ).

I wanted to generate a 30-second video, with 16:9 aspect ratio, from a set
of images and an audio with blend + zoom and pan effect.

Started this by just generating slide show of images from the video

**Slideshow of images**

ffmpeg -framerate 1/4 -start_number 1 -i 164470_%d.jpg -c:v libx264 -r
> 30 -pix_fmt yuv420p -vf scale=16:9 out.mp4


Then, tried adding an audio to the video, and this is the command I used.

ffmpeg -framerate 1/4 -start_number 1 -i 164470_%d.jpg -i audio.wav
> -c:v libx264 -tune stillimage -c:a aac -strict experimental -b:a 192k
> -pix_fmt yuv420p -shortest outWithAudioNew.mp4


With this command, I was able to create the video with zoom and pan
effects. It did not cycle through the images, though.

ffmpeg \
> -framerate 1/4 -start_number 1 -i 164470_%d.jpg \
> -vf "zoompan=z='if(lte(zoom,1.0),1.5,max(1.001,zoom-0.0015))':d=125" \
> -c:v libx264 -t 30 -s "800x450" outWithZoom.mp4



**To add in a blend effect I used this command:**

The uploaded file BrokenVideo-8min.mp4 has a video track timescale of
1000, exactly as the input file from the conversion.

(If I set it to 0, playback fails with every software.)

The file works fine with every software tested so far except QT,
this includes vlc, MPlayer, xine, GStreamer and WMP (which
contrary to what was claimed here all use different demuxers
afaik).

I cannot really comment on your issue but your input file has 30bpp,
your h264 output file only 12, so there has to be a difference wrt the
colour representation.

[FFmpeg-user] dpx to prores & h.264 - color shift

[Andreas Hummel]

Hi there,

i'm struggeling with the conversion from dpx files via ffmpeg to prores and
h.264 movie files on a windows machine. In the past days i read a lot about
the different flags and options but couldnt figure out what the 'best'
conversion technique is.
At the moment i'm getting a slight hue shift in the encoded videos and i
don't know where it's coming from. Probably i'm using too many options or
false flags but i thought, this list might give me a hint to solve the
problem at it's core.

Somehow i always get the color shift, regardless which options i try with
ffmpeg on the command line. The only way to obtain a 1:1 color
representation in a prores file was via Nuke from TheFoundry.

For h.264 i've got almost the same issue plus settle banding artefacts in
dark areas with a gradient. I tried to minimize the artefacts in the
gradient but couldn't find a suitable option yet.

Here you may find a comparison image:
http://www.directupload.net/file/d/4506/satnse88_jpg.htm

Full resolution can be found here:
http://uploaded.net/file/e02zd4ct

Zoom is at 100%. The left image shows a frame from the dpx sequence, 2nd is
the ffmpeg prores and 3rd picture shows a crop of my best attempt to encode
it with h264.

Or is that already the 'best' output i can get?

Thanks in advance for your help.

Cheers,
Andreas

Has anyone actually looked at the MP4 file, BrokenVideo-8min.mp4? It was
written with a video track timescale of 0, a track duration of 0 and due to
that, outrageous packet durations. Regardless of the quality of input
(which I'm sure was bad), the muxer should still be able to detect that
something is obviously wrong. In this case, the muxer should probably just
fail with an error. No reasonable person should expect MP4s written this
way to work correctly. Based on the fact that ffmpeg is writing timescale 0
and duration 0, I'd say this should probably be considered a bug. But
that's just my opinion.

MP4 files are specified by a standard. If a player can not handle some file
adhering to that standard, that is its fault. Bugs in third-party software
should not restrict FFmpeg users from creating valid files they want, and it
is not FFmpeg's task to document third party's bugs.

FFmpeg may document a well known bug in a well known third party software,
but this this would be a service offered as a convenience, not a duty.

[FFmpeg-user] Embedding cover artwork in video files

[Joe Dickerson]

I'm trying to embed cover artwork into my video files (all .mp4 format).  I
haven't been able to find any definitive answer on whether or not ffmpeg
can accomplish this or not.  Some people said they have successfully
accomplished this and provided code that worked (from forum posts dated a
year or much later ago), but unfortunately none of them have worked for
me.  As a work around I decided to use mp4art (I understand many programs
can embed, but I'm specifically looking for CLI) and it worked
beautifully.  I created a .bat file to make ffmpeg copy a video/audio and
mux external .srt file, then call mp4art and embed poster.jpg.  The bat
file was integrated into my right click menu via registry.  Here is the bat
file:


@echo off
for /F %%i in ('dir /b *.srt') do (
   goto :external
)
setlocal ENABLEDELAYEDEXPANSION
set fName=%1
set ffmpeg="F:\Apps\Media\FFMPEG\bin\ffmpeg.exe"
set mp4art="F:\Apps\Media\FFMPEG\MP4art\mp4art.exe"
for /f "tokens=* delims= " %%F in ('echo %fName%') do (
%ffmpeg% -i "%%~fF" -f srt -i "%%~fF" -c:v copy -c:a copy -c:s mov_text
-metadata:s:s:0 language=eng "%%~dpnF_new.mp4"
%mp4art% -f --add folder.jpg "%%~dpnF_new.mp4"
pause
)
exit
:external
setlocal ENABLEDELAYEDEXPANSION
set fName=%1
set ffmpeg="F:\Apps\Media\FFMPEG\bin\ffmpeg.exe"
set mp4art="F:\Apps\Media\FFMPEG\MP4art\mp4art.exe"
for /f "tokens=* delims= " %%F in ('echo %fName%') do (
%ffmpeg% -i "%%~fF" -i "%%~dpnF.eng.srt" -c:v copy -c:a copy -c:s mov_text
-metadata:s:s:0 language=eng "%%~dpnF_new.mp4"
%mp4art% -f --add folder.jpg "%%~dpnF_new.mp4"
)
exit



As stated before, this works great.  I would really love to remove mp4art
and just stick with ffmpeg.  Is there any way to embed cover art?  I seem
to find plenty of examples for music, but the movie examples I've found
don't work.

Thanks in advance and thank you for this amazingly flexible and strong
program!!
