    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).

    Code:
    mencoder -oac copy -ovc x264 -o out.avi in.ts
    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.
    Has anyone a simple solution for this problem?

    Thanks a lot,
    Sven

  2. 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
    lead to the wanted result (copying the first two stereo streams, stripping the DD2.0 stream)
    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 #0.1[0xc0](deu): Audio: mp2, 48000 Hz, stereo, 160 kb/s
    Stream #0.2[0xc1](eng): Audio: mp2, 48000 Hz, stereo, 160 kb/s
    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
    Ok, this is out of topic in my own post, but I got a problem configuring the h264 codec. The default settings lead to a really ugly video stream. I used the options from http://rob.opendot.cl/index.php/useful-stuff/ffmpeg-x264-encoding-guide/, but the look of video didn't change a bit. -vcodec mpeg4 leads to a similar ugly result!
    I looking for settings that lead to a result comparable to the original mpeg2 stream.

  4. your version of ffmpeg is OUTDATED!, x264 on 2007 was is early stage...

    add to your repository debian-multimedia

    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.

  6. 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.

  8. thanks for the info, i don't knew of recent "incompatibility", that's another plus to standard debian

    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
    which seems only one person in the google world encountered before.

    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...

  10. for bitrate..

    just edit your ffmpeg string, and add the -b parameter, for bitrate

    ffmpeg -i in.ts out.avi -vcodec h264 -b 1500000 -acodec copy -map 0:0 -map 0:1 -map 0:2 -newaudio

    EDIT: just for learing pourpose you can study the command line produced by WinFF or AutoFF

    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!

    in autoff you can specify the final size, and bitrate will be computed automatically (and applied to whatever video codec selected)

    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...
    I was just writing this replay, when I found the bug!
    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
    does work, but video is still encoded at 500k. It has to be e.g. like this
    Code:
    ffmpeg -i in.ts -vcodec h264 -b 1500000 out.avi -acodec copy -map 0:0 -map 0:1 -map 0:2 -newaudio
    The output file must not be specified before the codec parameters. ffmpeg is very curious about its parameter list, e.g. specifying in this example the output file at the end of the command line, leads to an syntax error
    Code:
    ffmpeg -i in.ts -vcodec h264 -b 1500000 -acodec copy -map 0:0 -map 0:1 -map 0:2 -newaudio out.avi
    Many thanks to buzzqw and GMaq for your help and time!
    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)

    why -newaudio option ? isn't needed afaik.. and.. -map 0:0 ... it's a unneeded plus

    Actually, no... at least not in my version 3:0.cvs20070307-5ubuntu7+medibuntu1

    For the source:
    Stream #0.1[0xc0](deu): Audio: mp2, 48000 Hz, stereo, 160 kb/s
    Stream #0.2[0xc1](eng): Audio: mp2, 48000 Hz, stereo, 160 kb/s
    Stream #0.3[0x80](deu): Audio: ac3, 48000 Hz, stereo, 448 kb/s

    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).

    Seems like ffmpeg doesn't know that it's fed with. could it be that your transport stream is encrypted?

    yes the file is encrypted. it only opens on the TV receiver.

  20. that's your problem
    ffmpeg can't decrypt and thus not do anything with it.
