Hi all,
I have some ts files directly recorded from the sat receiver to the hard disk, which I now want to encode with mencoder to an avi container using x264 as video codec (2GB / hour is way too big).
This works pretty fine, but if a ts file has more than one audio stream, the option -oac copy takes only the first audio stream. I am searching now the net a few days for a simple solution (without demuxing the ts file), without a result.Code:mencoder -oac copy -ovc x264 -o out.avi in.ts
Has anyone a simple solution for this problem?
Thanks a lot,
Sven

humble suggestion, try with AutoFF (NOTE COPY AUDIO ISN'T WORKING ACTUALLY, only encoding it)
thanks!

Thanks for the tips!
It was not easy to figure it out of the ffmpeg documentation but finally the command line
Code:ffmpeg -i in.ts out.avi -vcodec h264 -acodec copy -map 0:0 -map 0:1 -map 0:2 -newaudio
Input #0, mpegts, from 'in.ts':
Duration: 00:41:55.7, start: 1288.327522, bitrate: 7694 kb/s
Stream #0.0[0xe0]: Video: mpeg2video, yuv420p, 720x576, 6800 kb/s, 25.00 fps(r)

Stream #0.3[0x80](deu): Audio: 0x0000, 48000 Hz, stereo, 448 kb/s
Output #0, avi, to 'out.avi':
Stream #0.0: Video: mpeg4, yuv420p, 720x576, q=2-31, 200 kb/s, 25.00 fps(c)
Stream #0.1: Audio: mp2, 48000 Hz, stereo, 64 kb/s
Stream #0.2: Audio: 0x0000, 48000 Hz, stereo, 160 kb/s
Stream mapping:
Stream #0.0 -> #0.0
Stream #0.1 -> #0.1
Stream #0.2 -> #0.2
I looking for settings that lead to a result comparable to the original mpeg2 stream.

Hello,
With all due respect to buzzqw, if you are using Ubuntu you certainly do not want to use the ffmpeg from debian-multimedia, it has numerous dependency conflicts with mjpegtools, mencoder, avidemux and especially libfaad2. Go to www.medibuntu.org and follow the instructions on adding their repo to get a fully enabled ffmpeg with a version of x264 that works great with AutoFF in Ubuntu. Judging by the version you have posted it would appear to be the stock one that comes with Ubuntu and is very limited in use.My Site: http://www.bandshed.net/AVLinux.html
My Guide: https://forum.videohelp.com/topic330839.html -
well i must admit that i use debian sid.. so dependency are all resolved.. automagically by aptitude/dpkg...
thanks GMaq, i will pay more attention next time

buzzqw,
Well it should be that way, Ubuntu and Debian share a common base but little else any more, debian-multimedia used to be very compatible with Ubuntu up until 7.10, Unfortunately that is no longer the case.My Site: http://www.bandshed.net/AVLinux.html
My Guide: https://forum.videohelp.com/topic330839.html -
thanks for the info, i don't knew of recent "incompatibility", that's another plus to standard debian
BHHHDConvertToX, AutoMen, AutoMKV Developer -
First, thanks for all replies!
I tried the ffmpeg version from debian-multimedia, which is actually not working. It returned these strange[mp2 @ 0xb7d739f0]encoding 0 channel(s) is not allowed in mp2
Error while opening codec for output stream #0.1 - maybe incorrect parameters such as bit_rate, rate, width or height
As recommended I switched to www.medibuntu.org (thanks for that tip!!!), and ffmpeg works again!
But the video using h264 or mpeg4 still looks just awful! No wonder, the video gets encoded at 500kBit... -

sven_911,
If you don't specify a bitrate ffmpeg will just apply whatever default, which in the case of x264 is 500kb. Are you using AutoFF to do this or the commandline? I am not at my computer with AutoFF installed right now but I'm certain you can change the bitrate to whatever you like, there is a tab that is specifically for x264 in ffmpeg.
**EDIT** Buzz typed faster!My Site: http://www.bandshed.net/AVLinux.html
My Guide: https://forum.videohelp.com/topic330839.html -
@GMaq
in autoff you can specify the final size, and bitrate will be computed automatically (and applied to whatever video codec selected)
BHHHDConvertToX, AutoMen, AutoMKV Developer -
I tried the -b parameter already some time ago, but the codec insists on the 500k limit. I used AutoFF to get a more complex set of parameters...
The command line
Code:ffmpeg -i in.ts out.avi -vcodec h264 -b 1500000 -acodec copy -map 0:0 -map 0:1 -map 0:2 -newaudio
Code:ffmpeg -i in.ts -vcodec h264 -b 1500000 out.avi -acodec copy -map 0:0 -map 0:1 -map 0:2 -newaudio
Code:ffmpeg -i in.ts -vcodec h264 -b 1500000 -acodec copy -map 0:0 -map 0:1 -map 0:2 -newaudio out.avi
Hope this helps some of the frustrated ffmpeg command line users (wild guess) out there. -
Sven_911,
Glad you got it to work, many versions of ffmpeg including the current medibuntu one will also honor bitrate flags by adding "k" to the bitrate (ie: -b 1500k instead of 1500000)My Site: http://www.bandshed.net/AVLinux.html
My Guide: https://forum.videohelp.com/topic330839.html -
@sven_911
why -newaudio option ? isn't needed afaik.. and.. -map 0:0 ... it's a unneeded plus

ffmpeg -i in.ts out.avi -vcodec h264 -acodec copy is equal to
ffmpeg -i in.ts out.avi -vcodec h264 -acodec copy -map 0:0 -map 0:1
both lead to
Output #0, avi, to 'out.avi':
Stream #0.0: Video: mpeg4, yuv420p, 720x576, q=2-31, 200 kb/s, 25.00 fps(c)
Stream #0.1: Audio: mp2, 48000 Hz, stereo, 64 kb/s
Stream mapping:
Stream #0.0 -> #0.0
Stream #0.1 -> #0.1
If you want to add a second audio stream, you have to provide the full mapping info
-map 0:0 -map 0:1 -map 0:2".
But this alone leads to the error
Number of stream maps must match number of output streams.
For each audio stream beyond the first, you have to add -newaudio (1 video + 1 audio stream is default).
So, the correct mapping for two audio streams is
-map 0:0 -map 0:2 -map 0:3 -newaudio (stripping stream 0:1),
for all three
-map 0:0 -map 0:3 -map 0:2 -newaudio -map 0:1 -newaudio (inverted audio stream order). -
my receiver created 3 files 000.dvr 000.ts info3.dvr
it's a coded video and I can't open it.
please help. how to break the coding?

yes the file is encrypted. it only opens on the TV receiver.
-
there must be some way. how to remove encryption?
