Hi Soopafresh,

Thanks! This are the most extensive descriptions I've seen so far. As you know FFmpeg info is scarce.

Tried a few of the examples and was amazed MPEG-2 muxing worked. Up to now I considered FFmpeg unusable for muxing. Always had out of sync audio. It's simply the "1" after -copyts and the position where to put it, but you have to know it first.

Also thanks to Baldrick for preserving this valuable information for the future.

Chris.

Me too. When I read the muxing syntax I thought - "that actually works?". Also found some ffmpeg scripts from

http://eugenia.gnomefiles.org/2007/08/11/from-dvhdvavchd-to-ps3xbox360appletv/

Thanks to Eugenia Loli-Queru. http://osnews.com/img/vegas/ffmpeg-templates.zip They cover some rarer formats (h264 encoding) that ffmpeg supports as well, although I found they work best with celtic_druid's 8000 series builds from 2007.

Hi Soopafresh,

I attached a template adaption for Avanti from the IPHONE example. It's x264 in mp4 and it's 16:9.
Please can you give me your opinion? I think I like "Eugenia Loli-Queru".

Chris.

Hmm, maybe the options are a bit out of date - the latest ffmpeg builds from http://ffdshow.faireal.net/mirror/ffmpeg/ have some different renamed options
Refer
http://forum.doom9.org/showthread.php?t=130587
eg
-acodec libmp3lame
-vcodec libx264
etc

I can't find a complete list for the new builds, so... where to from here ?

[45tripp]

ffmpeg -formats

[halsboss]

ffmpeg -formats

Yes, that showed the new versions replacement codes up under "codecs" alright (D=decode, E=encode ?) for the latest ffmpeg version from http://ffdshow.faireal.net/mirror/ffmpeg/

Thanks 45tripp.

Also, a prompter for upgraders, the newer versions of ffmpeg have also changed the bitrate setting terminology eg from "9400" to "9400k" ... and the newer "MP2" may possibly have some "playback choppiness" issue, try for yourself.

Supported file protocols:
file: http: pipe: rtp: tcp: udp:
Frame size, frame rate abbreviations:
ntsc pal qntsc qpal sntsc spal film ntsc-film sqcif qcif cif 4cif

Note, the names of encoders and decoders do not always match, so there are
several cases where the above table shows encoder only or decoder only entries
even though both encoding and decoding are supported. For example, the h263
decoder corresponds to the h263 and h263p encoders, for file formats it is even
worse.

Now, if only there was a way to list the abbreviations for presets, like "pal-dvd", in a commandline like this, which converts an extracted PAL HDTV interlaced 1080i video stream into a DVD-compatible PAL SD interlaced 576i video stream ready for DVD authoring...

"C:\SOFTWARE\ffmpeg\ffmpeg.exe" -y -i inputfile.mpv -target pal-dvd -ilme -ildct -flags +ildct+ilme -top 1 -sameq -maxrate 9400k -dc 10 -s 720x576 -aspect 16:9 -an outputfile.mpv

Be careful. The ffmpeg user mailing list confirms what I subsequently found out by testing and examining the bitrate in a btrate viewer... ffmpeg produces s bitrate spikes in the resulting output file which go outside the DVD spec.

Back to the ever-trusty HC !

could I impose on someone to help with what I'm thinking should be a simple command line?

I just need this:
ffmpeg.exe -i "q:\6 uncompressed.avi" -vcodec copy -acodec pcm_s16le -y "e:\dv conversions\6 uncompressed.mov"

but I want it to do this to all files in the source directory and I want it to save them all with the same source filename to a new directory.

Is there a simple way to do this?

thanks in advance!!!

[hydra3333]

Sure you want .mov and not .mp4 ? You'll need to be sure beforehand that the .AVI content (video and audio encoding codecs used) are valid inside the destination container you choose otherwise it'll just break.

have you considered a batch file ? if XP, something like this .BAT file in the source folder ...

@echo on
REM SETLOCAL ENABLEDELAYEDEXPANSION

set srcPATH=.\
set dstPATH=e:\dv conversions\

FOR %%A in ("%srcPATH%*.avi") DO ( 
REM ffmpeg.exe -i "%%A" -vcodec copy -acodec pcm_s16le -y "%dstPATH%%%~nA.MP4"
)
pause

I've REM'd out the code so you can just double-click on it to see what it would do ...

[thomasj]

Can ffmpeg mux in soft subtitles? I've tried but can't get the syntax right. Not really sure if it's possible or not...

To what container? mp4,mkv,avi,etc?

[thomasj]

Oops, MPEG2 or VOB.

[charlesdem]

thanks Hydra3333. Forgive my ignorance, but when I substitute my directories in your bathc file and run it, it shows shows me the lines. It doesn't seem to try to execute anything. And the reason I'm not going to mp4, is I'm trying to remux these as quicktime dv files instead of avi dv files. I just need the .mov extension. I don't want any recompression.


can I do something like:
ffmpeg.exe -i "q:\*.avi" -vcodec copy -acodec pcm_s16le -y "e:\dv conversions\*.mov" ??

will that work. Or, what would be the way to do this? I just need to convert a lot of files and leave the room.

thanks!

Didn't you read what hydra3333 said:

You want to delete the REM in front of the ffmpeg.exe line.

can I do something like:
ffmpeg.exe -i "q:\*.avi" -vcodec copy -acodec pcm_s16le -y "e:\dv conversions\*.mov" ??

No, that won't work. You need to call ffmpeg on each file individually. That's what hydra3333's script does.

[charlesdem]

Thank you. I know it's annoying when it seems someone didn't read the answer. I'm just under deadline and wasn't sure how to execute it. It's been a long time since I've worked with any kind of code. Thank you for your help.

[charlesdem]

so, I replaced the call to the internet version to the one in the local directory, and it seems to work but it's giving me an error message about the output directory. It seems to be adding c:\ to the output directory, even though I assigned k:\<directory name> to the destination directory. Any ideas why? Here's what it says exactly:

Stream #0.1: Audio: pcm_s16le, 32000 Hz, 2 channels, s16, 1024 kb/s
Could not open 'k:\uncompressed .DV files\c:\Audio Projects\DV Capture\251 - Cli
p 001.MP4'

it should just say k:\uncompressed .DV files\251 - Clip 001.mp4

thanks again

[hydra3333]

call to the internet version ? what internet version ?

copy'n'paste the script here exactly as you've edited it. Exactly - double-check it too. Can't diagnose what's happened without seeing what you've done with it 1st hand. For future reference, just about everyone will ask you this same thing in this situation.

(Also, in that script, you need the trailing \ on the foldernames don't forget.)

[charlesdem]

Sorry - here it is. Hope you're still online!
thanks!

@echo on
SETLOCAL ENABLEDELAYEDEXPANSION

set srcPATH=h:\
set dstPATH=e:\dv conversions\

FOR %%A in ("%srcPATH%*.avi") DO (
ffmpeg.exe -i "%%A" -vcodec copy -acodec pcm_s16le -y "%dstPATH%%%~dpnA.mov"
)
pause

[hydra3333]

Hmm, sorry a bug on my part, I'm too old for this. To squash it,

 "%dstPATH%%%~dpnA.mov"

should instead be

 "%dstPATH%%%~nA.mov"

That leaves off the drive and path from the %%A in the substitution and only retains the name portion.

Oops

Hence your new script should be

@echo on
SETLOCAL ENABLEDELAYEDEXPANSION

set srcPATH=h:\
set dstPATH=e:\dv conversions\

FOR %%A in ("%srcPATH%*.avi") DO ( 
ffmpeg.exe -i "%%A" -vcodec copy  -acodec pcm_s16le -y "%dstPATH%%%~nA.mov"
)
pause

Now, the final thing you need to worry about is the "ffmpeg.exe" statement.
Should it be something like "C:\SOFTWARE\ffmpeg.exe" or the bin folder underneath wherever you've placed the latest beta ffmpeg folder tree you extracted from the latest beta 32 bit static download at http://ffmpeg.arrozcru.org/autobuilds/ ?

Hi,

Sorry for asking a question on an old thread but i m hoping someone here might be able to help me.

I have an MPEG2-TS. I want to convert it to a different bit rate. What would be the command for that. currently I use the following:

ffmpeg -i <in file> -f mpegts -vcodec mpeg2video -qscale 1 -qmin 1 -acodec copy -intra output.ts

the problem with this is that even though the input TS has random_access_indicator set in some packets, no packets in the output have random_access_indicator set to 1.

[Farish]

Please let me know if there is something wrong in the command or some other option which i need to enable so that the output TS also has random_access_indicator set in the packets where it should be.

I have also tried using -g 30 in place of -intra but this doesnt help with the random_access_indicator.
