2 source videos in FFMPEG... how to map audio ?
21 juin 2012, par dcoffey3296i am currently placing 2 videos side by side in FFMPEG. Here is the command :
ffmpeg -i input.mov -vf "[in] scale=1280:720, pad=2*1280:720 [left]; movie=right.mov, scale=1280:720 [right]; [left][right] overlay=1280:0 [out]" -b:v 1000k -vcodec libx264 -an sidebyside.mp4
I now need to manage the audio. I keep trying to specify :
-acodec libfaac -ac 2 -map 0:1 -map 0:2
to take the 2 audio channels from the first input and use them. I keep getting the error :
[aformat @ 0x7febf2e01fc0] auto-inserting filter 'auto-inserted resampler 0' between the filter 'src' and the filter 'aformat'
[aresample @ 0x7febf2e02180] [SWR @ 0x7febf40dd000] Input channel layout isnt supported
Error opening filters!I'm looking for the best way to specify which video provides the audio ! Thanks for any advice !

Trying to compile x264 and ffmpeg for iPhone - "missing required architecture arm in file"
11 février 2013, par jtrimI'm trying to compile x264 for use in an iPhone application. I see there are instructions on how to compile ffmpeg for use on the platform here : http://lists.mplayerhq.hu/pipermail/ffmpeg-devel/2009-October/076618.html , but I can't seem to find anything this complete for compiling x264 on the iPhone. I've found this source tree : http://gitorious.org/x264-arm that seems to have support for the ARM platform.
Here is my config line :
./configure —cross-prefix=/usr/bin/ —host=arm-apple-darwin10 —extra-cflags="-B /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.2.sdk/usr/lib/ -I /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.2.sdk/usr/lib/"
...and inside
configure
I'm using the gas-preprocessor script (first link above) as my assembler :gas-preprocessor.pl gcc
When I start compiling, it chunks away for a little while, then it spits out these warnings and a huge list of undefined symbols :
ld : warning : option -s is obsolete and being ignored ld : warning : -force_cpusubtype_ALL will become unsupported for ARM architectures ld : warning : in /usr/lib/crt1.o, missing required architecture arm in file ld : warning : in /usr/X11R6/lib/libX11.dylib, missing required architecture arm in file ld : warning : in /usr/lib/libm.dylib, missing required architecture arm in file ld : warning : in /usr/lib/libpthread.dylib, missing required architecture arm in file ld : warning : in /usr/lib/libgcc_s.1.dylib, missing required architecture arm in file ld : warning : in /usr/lib/libSystem.dylib, missing required architecture arm in file Undefined symbols :
My guess would be that the problem has to do with the "missing required architecture arm in file" warning...any ideas ?

ffmpeg video encoding progress bar
16 février 2017, par Rahul TSWhen I run the conversion in the browser it simply shows the white blank space. Only after the conversion process page will load.
Please suggest how to implement a progress bar which shows the progress to the user when the video conversion takes place.
I have this in my php script
exec("ffmpeg -i filename.flv -sameq -ab 128 -s 640x480 filename.mp4");
so how should I change this script to get the progress details even to a file or directly as ouput in the page. Please can anyone give me a complete script/code to explain it in detail. Because I think I cant get the complete answers and so I am confused on what to do with this
