Batch video conversion

[panteragstk]

I've been looking for a way to convert .mov files to .ts or .m2ts for use in sagetv. The reason I want to be able to do this is sage splitter and .mov don't get along so well. I can easily convert with tsmuxer, but it doesn't support batch operations. The automatic trailer downloader on the mymovies.dk site supports "post processing" which I need a program that supports batch. Does anyone know of any software that will do what I'm asking?

I wrote this a while back to remux Apple Trailers into mkv with AC3 audio, using only tools that come with Sage, aside form MKVMerge. Just paste it into notepad and save it as a .bat file.

@echo OFF
cd d:\test\
set input=%1
set output=%input:.mov=.mkv%

if EXIST %output% GOTO EXISTS

D:\sageserver\sagetv\sagetvtranscoder.exe -i %input% > d:\test\fmt.txt 2>&1 
findstr /R "Audio.*5\.1" d:\test\fmt.txt
echo. %errorlevel%
if %ERRORLEVEL% EQU 0 GOTO DD

findstr /R "Audio.*stereo" d:\test\fmt.txt
echo. %errorlevel%
if %ERRORLEVEL% EQU 0 GOTO ST

goto ERR

Works quite well, just drop a file on top of it. You'll have to fix the paths of course, and you can remove the "REM" from "REM del %input%" and it will delete the source file for you.

Thanks. I'll give that a try. I don't know why the sage splitter makes .mov files play so blocky, but this might help.

[panteragstk]

That didn't work. MKV's use the same splitter as .mov files. If I convert to .m2ts or .ts it uses a different splitter and the playback issues go away.

[stanger89]

Interesting, the MKV's play fine on the extenders (though mov's don't).

Though it would be pretty easy to replace mkvmerge in that with tsmuxer.

It would except for the fact that tsmuxer requires a .meta file that contains the command line. I can't find any simple software that will do what I want. This is frustrating.

If I could find a way to automatically create the .meta file I would be in business.

I suck at creating batch files or even using command line .exe's. It's been too long since my dos days.

Here is the manual if anyone would like to help me out with this.

looking into this more it would seem that mencoder or ffmpeg could accomplish the same thing.

"mencoder.exe -oac copy -ovc copy"

the above would keep the audio and video in tact, but I have no idea how to get the file to output a .m2ts file. I would like to be able to run the batch file in the directory with the trailers and have it change all to .m2ts then send them to another directory after deleting the original files. How do I make that happen?

echo "V_MPEG4/ISO/AVC, D:\media\test\stream.h264, fps=25" >> temp.meta
echo "A_AC3, D:\media\test\stream.ac3, timeshift=-10000ms" >> temp.meta
tsmuxer --blah --blah --blah
del temp.meta

Of course that relies on you being able to parse out any extra info you need (timeshift, fps, etc) from elsewhere.

Thanks, I'm still trying to figure out a simple way to accomplish this task with ffmpeg now.

this are the parameters I have now " -i %1 -vcodec copy -acodec copy %1.m2ts" but nothing happens.

if I'm correct %1 is like having *.mov right? I'm starting to remember how to create these files, but it is taking a while.

[panteragstk]

ffmpeg doesn't support .m2ts. That answers that question.

[Spectrum]

You won't be able to use wildcards like *.mov due to the way the command interperter will expand things. You would have to call the .bat fiile once for each .mov. That can be accomplished using a for statement from the command line

for %i in (*.mov) do myconverter.bat %i

Remember that if you use a for statement from inside a batch file to double the % on the vars, so %i would be %%i

Also the way you have that written it would expand to

ffmpegenc -i mov1.mov -vcodec copy -acodec copy mov1.mov.m2ts

If you want to use a for loop from outside the batch file to catch all the .movs in a directory and not get the .mov.m2ts extenion concatenation, you could have the encoder parms like

ffmpegenc -i %1 -vcodec copy -acodec copy %2

then call batch file from a for loop

for %i in (*.mov) do myconverter.bat %i~ni.m2ts

That would encode movie1.mov to movie1.m2ts.

There are other ways to skin that cat, but that's the first one that comes to mind

You might also check out VLC from videolan.org. It does support command line work, and has many options. Getting everything figured out might be tricky, but once you get it done, it should be smooth.
