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 says : "option framerate not found"
16 juillet 2013, par JasonGood afternoon.
I've been trying to use ffmpeg to split a .mpeg into a sequence of .jpeg images. Please note that this is the inverse problem of the one specified here, but the problem I'm facing is not the same as the problem the author of that thread is facing.
Specifically, I have tried all the following mpeg codecs available in my ffmpeg installation :
DEV D ffv1 FFmpeg video codec #1
DEVSD ffvhuff Huffyuv FFmpeg variant
DEVSDT mpeg1video MPEG-1 video
D V DT mpeg1video_vdpau MPEG-1 video (VDPAU acceleration)
D V D mpeg2_crystalhd MPEG-2 Video (CrystalHD acceleration)
DEVSDT mpeg2video MPEG-2 video
DEVSDT mpeg4 MPEG-4 part 2
D V D mpeg4_crystalhd MPEG-4 Part 2 (CrystalHD acceleration)
D V DT mpeg4_vdpau MPEG-4 part 2 (VDPAU)
D VSDT mpegvideo MPEG-1 video
D V DT mpegvideo_vdpau MPEG-1/2 video (VDPAU acceleration)
D VSDT mpegvideo_xvmc MPEG-1/2 video XvMC (X-Video Motion Compensation)
DEVSD msmpeg4 MPEG-4 part 2 Microsoft variant version 3
D V D msmpeg4_crystalhd MPEG-4 Part 2 Microsoft variant version 3 (CrystalHD acceleration)
D VSD msmpeg4v1 MPEG-4 part 2 Microsoft variant version 1
DEVSD msmpeg4v2 MPEG-4 part 2 Microsoft variant version 2I've tried supplying ffmpeg with all different codecs to try to split an input .mpeg video file with 2548 frames into 2548 .jpegs, by using the -vcodec option :
ffmpeg -r 2548 -i frames.mpeg frames_%06d.jpg -vcodec $codecwhere
$codecis any codec among the ones listed above, e.g.ffv1,mpeg4, etc. However, all my efforts result in the following error :[NULL @ 0x1948f20] Value 4707126720094797824.000000 for parameter 'probesize' out of range

Option framerate not found.Which is weird, because I've actually specified the frame rate parameter through the -r switch. I googled a bit and it appears that this error was mentioned approximately a year and a half ago on the ffmpeg bug tracker but that information makes little sense to me because it's relevant to the devs. Curiously, if I interchange the position of the parameters and put -r after -i or even after -vcodec, the error message changes to :
