I have some video files (.avi and .swf) & I need to convert them to the following format:
Stream #0.0(eng): Video: mjpeg, yuvj422p, 320x240, 30 tbr, 30 tbn, 30 tbc
Stream #0.1(eng): Audio: pcm_u8, 8000 Hz, mono, s16, 64 kb/s
how to do this with mencoder or ffmpeg?
How do you loop a video a number of times in ffmpeg or mencoder? I made a ogv out of a gif. It loops 1 time, so it's less than a second.
View 4 Replies View RelatedI'm wondering if anyone distributes mplayer, mencoder, and ffmpeg, up-to-date builds of each and their associated dependencies (x264, faac, xvid, etc).I had to compile all that stuff myself and fought with it, and finally got it working.
If no one distributes latest builds, then I was thinking of going further with what I've done to help others: virtualbox lenny and automated compiles of all packages and putting up the builds, with latest revisions of mplayer and ffmpeg from their source code repos. Using LD_LIBRARY_PATH to isolate the build so any modern linux can run the produced binaries, with only glibc as a dependency.
I am trying to use ffmpeg and mencoder to slice a portion of my video out but the audio is always 2 seconds out of sync.
ffmpeg -i bird.avs.MP4 -acodec copy -vcodec copy -ss 00:08:40 -t 00:01:00 test.mp4
mencoder -ss 00:08:40 -endpos 00:01:00 -oac copy -ovc copy bird.avs.MP4 -o test.mp4

I have a MKV file and need to convert it down to XVID to allow some of my other streamers to use the file. However, when I try I get the following errors:

Maybe you are playing a non-interleaved stream/file or the codec failed?2:128] For AVI files, try to force non-interleaved mode with the -ni option.
The file details are :

and the command I am using to run the conversion is:

mencoder "Test 1080p.mkv" -channels 6 -ovc xvid -oac mp3lame -xvidencopts pass=1 -o /dev/null -lameopts cbr:br=128
I presume that it has something to do with the 6 channel DTS audio and the conversion to mp3 because if I change the command to just copy the audio all progresses fine.
I'm trying to convert a .MTS video file to .mov, and I need to use ffmpeg, because I want it to be scriptable.I managed to convert the file to .avi using this command:Code:ffmpeg -i INPUT.MTS -vcodec libxvid -b 18000k -acodec libmp3lame -deinterlace -ab 192k -s 1280x720 -r 50 OUTPUT.avi
View 3 Replies View RelatedI've got a bunch of HD files in .mkv format that I want to convert to a format that the 360 will read (currently just trying .avi files) so I can stream the media to my xbox360. I'd rather avoid transcoding the entire file, so I tried unpacking the .mkv file into audio and video (and subtitle if necessary) and repacking said file into avi using ffmpeg. The repacking is where I am having the problem. Here's the commands I tried at first (it might look familiar):
Code:
mkvextract tracks file.mkv 1:temp_video.avi 2:temp_audio.ogg 3:temp_sub.srt
ffmpeg -i temp_video.avi -i temp_audio.ogg -vcodec copy file.avi
However, I keep getting this annoying error:
Code:
Error while opening codec for output stream #0.1 - maybe incorrect parameters such as bit_rate, rate, width or height Where stream #0.1 is the output audio stream to the .avi file. I think I have narrowed it down to the fact that the input streams are all 6 channel (5.1 surround sound) which mp2 doesn't support (the ffmpeg audio default) so I did this instead:
Code:
ffmpeg -i temp_video.avi -i temp_audio.ogg -vcodec copy -acodec libmp3lame file.avi
I'm still getting the same error, but when I use
Code:
ffmpeg -i temp_video.avi -i temp_audio.ogg -vcodec copy -acodec libmp3lame -ac 2 file.avi
to change the sound to stereo it works. Problem is I'd like to keep my media in surround sound. Any thoughts on how to get all 6 channels in the new mp3 file? I'm fairly certain that mp3s support 5.1. And after some messing around, I haven't found that my ffmpeg can transcode audio format from 5.1 back to 5.1. So since (I think) the 360 can play .ac3 files I decided to just copy both the video and audio file to the .avi file sans transcoding using
Code:
ffmpeg -i temp_video.avi -i temp_audio.ogg -vcodec copy -acodec copy file.avi
however now about halfway through, I run into this error:
Code:
NULL @ 0x22f3a00]error, non monotone timestamps 62562 >= 62562
av_interleaved_write_frame(): Error while opening file I can't seem to find any solution to this problem anywhere online, does anyone know how to get around this? I'd prefer to use ffmpeg for this if possible. (so I can write a script and just attack an entire directory at once) For what it's worth, I'm using the latest ffmpeg in the ubuntu (karmic) default repositories.

I have a .mkv container with proper video (h264/~6000kbps) and audio (DTS/1500kbps). For some reason I want to have similar quality but with another video and audio codecs. For video it goes well and ffmpeg is very helpful here, no problems. Also, I want DTS to become AC3/320-448kbps/5-6 channels. Commands like this:
Quote:
ffmpeg -i in.dts/mkv -acodec ac3 -ac 5 -ab 448k out.ac3
gives me not proper reordered sound in channels, so I hear center on the right, music on the left, etc.
Is there a way to make that properly with ffmpeg?
Also, I have a question about multi core encoding cause I have a quad processor. Ffmpeg seems not using them in all the way, I get something like 25% of CPU usage while encoding. Command -threads, even using the h264, does not make any extra load of cpu.
I'm making little animated bits in GIMP with the gap package. I can only get GIMP to encode the files as .avi. Problem here is that when I try to use any converter, it compresses 80MB files down to 1MB-4MB files and, unsurprisingly, the video quality is terrible. WinFF and ffmpeg (via terminal) output at a drastically reduced size. Is there some way to keep the files big/big-ish? I don't want to lose any detail.

I am looking for an option to convert .vob file to mp4 format. Command "ffmpeg -i S.vob x.mp4" is giving error message "[libfaac @ 01cac110] Unable to load libfaac.dll". I tried to convert in other formats like .avi with the same command and got success. Conversion is decreasing the quality like hell. Though size of the file after conversion is as big as original then why this bad quality.

i am using Ubuntu 11.04 on my computer system. I urgently need a good video converter for converting videos.I have already installed FFmpeg and men-coder,Winff etc. The problem is each has its own drawback.For instance ffmpeg cannot convert a .avi to .3gp with audio working. My preferences are the converter should be user friendly, should support all popular video formats.
