Hi,
I've created 5.1 channel aac-lc audio from 5.1 channel ac-3 audio.
However, the sample entry of "mp4a" box show channel_count as "2", not "6".
Howerver, the MPEG-4 elementary stream descriptor in "esds" box describes
channel count as 6.
Command
ffmpeg -loglevel debug -i source.mp4
Hi,
Thanks for the suggestion. Forgot to tell that Line 1 is the real output
whereas Line 2 is a silenced source for nullifying front channels. I use
two cables separately for rear and front jacks, with earphones attached to
front one's extension and stereos to the rear's; Would try the quad

Hi everyone,
I'm an amateurish sound artist and my personal English alias is Thomas. New
and nice to be with you.
Let us get to know my purpose here with one line of Windows script created
on my own:
ffmpeg -f dshow -rtbufsize 4 -i audio="Line 1 (Virtual Audio Cable)" -f

MPlayer is a media player with a guy. I think it uses ffmpeg? I would say
MPlayer is to a film projector and screen what ffmpeg is to a large darkroom
with all of its equipment.

It’s just two videos stitched side by side. You can crop out the
FFmpeg and MPlayer (differences and similarities)
Hi. Congratulations for FFmpeg. It is an excellent software.
I have been thinking about installing or FFmpeg or MPlayer, but not both.
I apologize, but I do not follow neither FFmpeg nor MPlayer developing.
I think FFmpeg is similar to MPlayer.
Thank you for your answer.
We are using a custom player and we need to have the option to show or not the
subtitles.
If the subtitles must not be encrypted, as stated by Apple, I am thinking in
encode video and audio with encryption in one ts file and do the same (without
encryption) in

Burning the subtitles into the video would be the only way with his.

Indeed, you {recall, remember} correctly! RAWcooked by Jérôme

What created the hls stream with dvbsub subtitles that you
used to test the player?
Please avoid top-posting here, Carl Eugen
At this time I use a vlc lib to play the stream.
I am able to change audios and enable/disable subtitles with it.

First of all, I am glad to be here.
Thanks fo your patience.
I am working in a project where I have to encrypt a hls stream with AES-128.
I have made it using ffmpeg, in a test mp4 file, but without the subtitles,
wich are in dvbsub format.
As, in the input stream, the subtitles are in dvbsub

So your question is not if FFmpeg
Hi Sir/Madam,
I have downloaded a half SSB 3D video from YouTube. I want to extract 2 videos
(Both Left & Right View Separately) from Source File. How can I do that? I
intend to use ffmpeg or x264 libraries.Please provide me assistance
Regards,Shivraj
Dear list,
we have issues with wrapping a image sequence consisting of dpx version 2
pictures into ffv1 mkv. After unwrapping we get the images as dpx version 1
pictures. Is it because ffmpeg can't handle dpx version 2?
This is the console output:
C:\temp>ffmpeg -i "L:\a5595_Filme aus
Thanks you for your suggestion, I will try with a more recent version.
