Plz help, VP6A mkv only plays in avidemux!

[poisondeathray]

I have no idea what the dF pF etc...stand for

%%~dF = drive letter
%%~pF = path
%%~nF= file name (not including the extension)

The sequence builds the drive letter, path, and file name without the extension -- so that a new extension can be appended.

Thanks .

I have this list of "things to learn"; this topic along with a bunch of dos stuff is on that list (and lots of crazy avisynth stuff ugggh)

I had your recursive batch audio post bookmarked for when I had time to learn in the future

thx for your reply, yes i tried a few of the recommended players ... they won't play on my android phone ...

So I did a search for "avidemux android preset" and very quickly found this:

https://help.ubuntu.com/community/AndroidVideoEncoding

That may be a ubuntu link but I don't see why it wouldn't work in the windows version of avidemux. I use avidemux or handbrake in linux and that's what I used to use in windows and the codec libraries are the same. And neither needs stupid codec packs.

can you plz write a script for a similar but different set of files? thx

p.s. i removed -map 0:2 from previous script because it gave error, it did encode but the final file had no audio!

^
^ Wrong question

[UnD3R0aTh]

what?! xD

similar codec, different group of files, that has only one video stream!

p.s. i removed -map 0:2 from previous script because it gave error, it did encode but the final file had no audio!

You need to figure out which stream has the audio you want and change the -map specifier to that stream. Probably -map 0:1.

[UnD3R0aTh]

i set map to map 0:1, now it gives mp4 files containing audio only!

edit i think i figured it out, map 0:0 for video, map 0:1 for audio cheers

[jagabo]

edit i think i figured it out, map 0:0 for video, map 0:1 for audio cheers

Yes, that's what I meant. -map 0:0 means file 0, track 0. -map 0:1 means file 0, track 1.

[UnD3R0aTh]

guyz the file sizes i'm getting are big, how can i get equal or less sizes?

[jagabo]

Use a lower bitrate.

[UnD3R0aTh]

which command, what number?



for /F "delims=;" %%F in (mkv.txt) do "ffmpeg.exe" -i "%%F" -map 0:0 -map 0:1 -c:v libx264 -profile:v baseline -b:v 500k -x264opts nal-hrd=vbr:vbv-bufsize=2500:vbv-maxrate=2500 -c:a copy "%%~dF%%~pF%%~nF.mp4"

[poisondeathray]

-b:v 500k

this means bitrate encoding for video stream is 500kb/s

filesize = bitrate * running time

So if you decrease bitrate by 1/2 (e.g. -b:v 250k), the video stream filesize will be reduced by 1/2 compared to if you had encoded with 500kb/s (note that doesn't include audio , because you have to add up both audio & video bitrates , plus accessory streams and container overhead)


There might be something else going on, it would be better if you posted a sample
