Escape character "|" error (Linux command)
22 mars 2013, par user1812668I'm trying to run a Linux command in Java.
This is the command :
"ffmpeg -i rtmp ://192.168.1.112/garage/stream26g -f mpegts -acodec libmp3lame -ar 48000 -ab 64000 -s 480x320 -r 30 -vcodec libx264 -b 544k -flags +loop -cmp +chroma -partitions +parti4x4+partp8x8+partb8x8 -subq 5 -trellis 2 -refs 0 -coder 0 -me_range 16 -keyint_min 25 -sc_threshold 40 -i_qfactor 0.71 -bt 200k -maxrate 544k -bufsize 544k -rc_eq 'blurCplx^(1-qComp)' -qcomp 0.6 -qmin 10 -qmax 30 -qdiff 4 -level 30 -aspect 480:320 -g 30 -async 2 - | vod - 10 stream/stream26g/sample stream/stream26g/stream.m3u8 http://www.tshizerbia.com//video/ 5" ;
But it gives me an error :
Unable to find a suitable output format for |
And I don't know what is the problem
I used this to run the command
Process p = Runtime.getRuntime().exec(command);
If I put
\\|
in the string the message error is :Unable to find a suitable output format for |
How can I escape this character ? Any ideas ?

ffmpeg : How to make -vf "movie=..." point to another folder [closed]
21 mars 2013, par evilheinzI'm trying to watermark a video with another video placed in a different folder.
Source video [video.mov] is placed in a folder like
x :\test1
Overlay video [overlay.mov] is placed in
x :\test2
I'm using this command :
ffmpeg.exe -y -i x:\test1\video.mov -vf "movie=x:\test2\overlay.mov [watermark]; [in][watermark] overlay=0:0 [out]" x:\test3\video_overlay.mov
But I'm getting an error saying
Missing key or no key/value separator found after key 'test2overlay.mov'
When placing all files in the same folder and using this :
ffmpeg.exe -y -i video.mov -vf "movie=overlay.mov [watermark]; [in][watermark] overlay=0:0 [out]" video_overlay.mov
everything works fine...
So how do I get the video filter to load the overlay file from a different folder on Windows ?
