Re: [FFmpeg-user] Setting colour range.

2018-11-27 Thread Martin Vignali

Doesn't seems like prores_ks do something about color_range.
The color difference between prores_ks and aw, have been fixed, by setting
the color prim, trc, space in prores frame header in prores_aw
(already in master, patch on mailing list about this, are only to restrict
the valid values)

As far as i know, quicktime (and prores), doesn't have a way to set as full
or legal range.
need to be interpreted as legal by default, but some app can use the
outside range information (like super white).

Re: [FFmpeg-user] HD MXF SMPTE ST377 Standard Compliance Problem with multiple IndexTableSegments carring Unique ID twins (maybe a bug)

2018-11-12 Thread Martin Vignali 
Hello,

I think this report is interesting.
Creating file for broadcast delivery, is not just about having a file which
play or doesn't play
It's mainly about passing Quality Control.

Even if a file can be play in most of software, if it doesn't pass
broadcaster QC, it will be reject.

In my use i always remux MXF generate by ffmpeg using bmxtranswrap, to have
"clean" mxf.

Mxf is a very complicated format, with very expensive "documentations".
Reason why, few people can improve it inside ffmpeg.

As suggested by Marton Balint, some developers (not me), have more chance
to work on it, with a financial support.
If you can sponsor it, you can try to contact developper who have recently
improve the mxfenc.

@Chris von Görstinger :
If you remux your file with bmx, does it still show warning in the MXF
Analyser ?

If yes, i suggest to create a bug report on trac.
Ideally, using an ffmpeg generator instead of a file as source.

[FFmpeg-user] How to choose pixfmt output for video generator

2018-10-09 Thread Martin Vignali 
Hello,

I would like to use a generator for testing
Some generator, seems to have several pix fmt supported, but can't find the
way to choose one

For example allyuv seems to support yuv444p, gbrp

./ffmpeg -f lavfi -i allyuv=rate=5:duration=1 -pix_fmt yuv444p -f null -
-loglevel debug
==> Output yuv444p

./ffmpeg -f lavfi -i allyuv=rate=5:duration=1 -pix_fmt gbrp -f null -
-loglevel debug
==> Following log, seems to output yuv444p then convert to gbrp

Use a lossy codec instead.

FFmpeg doesn't have an exr encoder yet.
The most difficult part, is to add float/half pixel format in ffmpeg,
before adding an exr encoder.
(for now ffmpeg exr decoder, decode data in 16bit (int) not in float)

Seems like the ffmpeg file is in YUV full range, and the Quicktime output
is in YUV legal range.
Also called jpeg range (= full range), and mpeg range (legal range).

[FFmpeg-user] Audio Meter filter

2018-03-30 Thread Martin Vignali 
Hello,

I would like to show an audio meter from an audio file (something like what
edit software display
or like Audacity display)

I try the showvolume filter, but the result is not what i would like to
have.

My command line :
"C:\ffmpeg-20180329-af043b8-win64-static\bin\ffmpeg.exe" -i
"D:\RefSon100Hz_Son_PCM18_03_30_18h21m17s.wav" -filter_complex
"[0:a]showvolume=w=340:h=5:o=v:f=1.:p=1.:t=0:m=r:v=0[v]" -map "[v]" -c:v
qtrle "D:\resAudioMeter004.mov"

My input test file :
https://we.tl/X6L69kEWAN

Contains : 1000 Hz -12Db, then - 18 db, then 0 Db.

If i use the peak option, i have no difference between -12 and -18 db
And the "scale" is not what i would like to have (would like to have -12 /
- 18 Db more close to the max level

If i use the rms option, the scale is very low for all "level", and no
differences between -12 and -18 Db.

Is there another filter for that ?

Thanks by advance

Hello,

Display window is not correctly support for all case in ffmpeg exr decoder.
Only datawindow < display window is supported, and if i correctly remember,
not for < 0 coordinates.

I begin to work on a patch for this, but i doesn't find time to finish it.
I will probably take a better look on this (but not soon), and it's
probably better to modify the decoder
to use planar format before implementing a full display/data window support.

[FFmpeg-user] How to make CBR AAC

2016-11-03 Thread Martin Vignali 
Hello,

I need to create mp4 file with aac audio with a 256kbits average bitrate.

The problem, is that my file, have lot of silence, but i need to have an
average audio bitrate very close to 256k.


Is there a way, to force the aac encoder to add some "fill" in order to
appear like a cbr bitrate (like X264 can do)

I try to increase the bitrate, but aac encoder seems to have a bitrate
limit, and even if i use the max allowed bitrate, the resulting file is
under 256kb/s (216 in that case)

[FFmpeg-user] Mov : how to set interlaced value of mov muxer

I would like to encode some progressive video to interlace quicktime

I try to use -top 1 and +ildct,
The frames seems to be compressed as interleaved, but the mov muxer, still
think it's a progressive frame. The codec name for xdcam is not the right
one, and the fiel value is not correct for prores or mov xdcam.

Output with prores encoding :

You mean removing --disable-asm or adding this configure option ?

Because i test witth --disable-asm, and same trouble

[FFmpeg-user] Compile ffmpeg on mips-qemu

2016-06-30 Thread Martin Vignali 
Hello,

I would like to compile ffmpeg on mips, in order to test the exr decoder on
it.

I try several configure line, but when i launch ffmpeg, i still have
"Illegal instruction"

I use qemu on mac os x, launch with this command :
qemu-system-mips64 -M malta -kernel ./vmlinux-3.2.0-4-5kc-malta -hda
./debian_wheezy_mips_standard.qcow2 -append "root=/dev/sda1 console=tty0"
-redir tcp:::22



Configure result :
./configure --arch=mips64 --prefix=../build --disable-ffplay
--disable-ffprobe --disable-ffserver --enable-zlib --disable-asm
--disable-videotoolbox --disable-audiotoolbox --disable-vda
--disable-everything --enable-demuxer=image2 --enable-muxer=framecrc
--disable-decoders --enable-decoder=exr --enable-protocol=file
--enable-protocol=pipe --enable-encoder=rawvideo --disable-doc

Re: [FFmpeg-user] converting broadcast wavs strips xml metadata

2015-04-20 Thread Martin Vignali 
Hello,

If i correctly remember you need to use -write_bext 1, in order to create
BWF file.

Best regards

Martin

 Hi Pete,

  ffmpeg supports decoding and encoding of broadcast wavs (bwf format)

  input file has a bext chunk in aXML format
  output file has no bext chunk

 The aXML chunk is intended to contain any valid XML document. The bext
 chunk is a rigid list of fixed length strings and dates. Having a bext
 chunk within an aXML chunk would be very unusual.

 The ffmpeg wav muxer supports bext but does not (yet) support the aXML
 chunk.

  i am using bwfmetaedit (http://bwfmetaedit.sourceforge.net) to verify
 bext data.

 wooo, someone uses that.
