having trouble converting mkv to avi

unclejed613 · 04-21-2012, 07:22 PM

and the stock mencoder (slack 13.37) doesn't have xvid support(?), so using a command line similar to

Quote:

mencoder abc.mkv -oac pcm -ovc xvid -xvidencopts bitrate=886 -sub ITC0101.srt -subfont-text-scale 3 -o zzz.avi

gives me an error saying -xvidencopts is not a valid option.

Firstly your best bet is either

http://slackbuilds.org/repository/13...imedia/ffmpeg/
Don't forget the dependencies

or

http://alien.slackbook.org/blog/vlc-2-0-1/

Secondly are you sure that it's a xvid codec inside that? A lot of stuff on the Internet now is x264.

it shouldnt matter what the input is as long as the mkv is playable. he is having troubles converting it to xvid.

so i installed VLC from alien bob's slackbuild, and tried converting a file and i got these errors

Code:

[NULL @ 0x8311900] Codec is experimental but experimental codecs are not enabled, see -strict -2
[0x83e6f50] avcodec encoder error: cannot open encoder
[0x9492cf0] stream_out_transcode stream out error: cannot find audio encoder (module:any fourcc:mp4a). Take a look few lines earlier to see possible reason.
[0x9492cf0] stream_out_transcode stream out error: cannot create audio chain
[0x839e470] main decoder error: cannot create packetizer output (mp4a)
x264 [info]: using SAR=181/204
x264 [info]: using cpu capabilities: MMX2 SSE2Slow SlowCTZ
x264 [info]: profile High, level 2.1

i thought the slackbuild (at least this one...)took care of the dependencies

my problem with ffmpeg seems to be it has a latex dependency (??? i thought latex was already part of slack)

Not sure why you installed vlc from the slackbuild Eric has precompiled packages one is capable of encoding while the other is not (make sure you get the encoding one)

As for ffmpeg & latex Slackware has tetex installed by default which is all it needs, as per the comment on slackbuilds.org

XVid is not a separate encoder in ffmpeg (and thus in MPlayer and VLC too).
From http://ffmpeg.org/faq.html#How-do-I-...th-ffmpeg_003f :

Quote:

3.8 How do I encode Xvid or DivX video with ffmpeg?

Both Xvid and DivX (version 4+) are implementations of the ISO MPEG-4 standard (note that there are many other coding formats that use this same standard). Thus, use ’-c:v mpeg4’ to encode in these formats. The default fourcc stored in an MPEG-4-coded file will be ’FMP4’. If you want a different fourcc, use the ’-vtag’ option. E.g., ’-vtag xvid’ will force the fourcc ’xvid’ to be stored as the video fourcc rather than the default.

Mind you it is possible to compile FFmpeg against the external xvid library and use this:

Code:

andrew@skamandros~$ ffmpeg -codecs 2>/dev/null | grep xvid
  EV    libxvid         libxvidcore MPEG-4 part 2

But for the most part it would be better to use x264 to produce h.264 video anyway...

unclejed613 · 04-22-2012, 01:06 PM

well i think i got it figured out.. vlc continued encoding, and i got video but no audio. i tried several common audio formats but vlc would error out saying "your installation of ffmpeg is crippled". i finally settled on AC3 which i hope makes the xbox happy. i'm serving files for an xbox using minidlna.

i just tried playing the file on the xbox, and it doesn't play....

xbox likes AAC but not AC3... vlc's AAC encoder isn't working

Since you are streaming to an XBox, have you tried transcoding to mp4? I have some dvd's ripped with handbrake that I ripped to mp4 and they work fine with the ps3, not sure about XBox as mine doesn't see my server.

unclejed613 · 04-22-2012, 05:14 PM

so here's what i found out in the meantime...

Code:

Xbox 360 console support for AVI

File extensions: .avi, .divx
Containers: AVI
Video profiles: MPEG-4 Part 2 (Simple Profile and Advanced Simple Profile)
Video bit rate: 5 Mbps with resolutions of 1280 × 720 at 30 fps. See the question about max bit rate, resolution, and frames per second.
Audio profiles: Dolby® Digital (2 channel and 5.1 channel), MP3
Audio max bit rate: No restrictions. See the question about max bit rate, resolution, and frames per second.

Xbox 360 console support for H.264

File extensions: .mp4, .m4v, mp4v, .mov, .avi
Containers: MPEG-4, QuickTime
Video profiles: Baseline, main, and high (up to level 4.1)
Video bit rate: 10 Mbps with resolutions of 1920 × 1080 at 30 fps. See the question about max bit rate, resolution, and frames per second.
Audio profiles: AAC, 2-channel, Low Complexity
Audio max bit rate: No restrictions. See the question about max bit rate, resolution, and frames per second.

Xbox 360 console support for MPEG-4 Part 2

File extensions: .mp4, .m4v, .mp4v, .mov, .avi
Containers: MPEG-4, QuickTime
Video profiles: MPEG-4 Part 2 (Simple Profile and Advanced Simple Profile)
Video bit rate: 5 Mbps with resolutions of 1280 × 720 at 30 fps. See the question about max bit rate, resolution, and frames per second.
Audio profiles: AAC, 2-channel, Low Complexity
Audio max bit rate: No restrictions. See the question about max bit rate, resolution, and frames per second.

Xbox 360 console support for WMV (VC-1)

File extensions: .wmv
Containers: ASF
Video profiles: WMV7 (WMV1), WMV8 (WMV2), WMV9 (WMV3), VC-1 (WVC1 or WMVA) in simple, main, and advanced up to level 3
Video bit rate: 15 Mbps with resolutions of 1920 × 1080 at 30 fps. See the question about max bit rate, resolution, and frames per second.
Audio profiles: WMA7/8, WMA9 Pro (stereo and 5.1), WMA Lossless
Audio max bit rate: No restrictions. See the question about max bit rate, resolution, and frames per second.

so these are the file structures the xbox will play, unfortunately my install of vlc, and ffmpeg are limited, so i will get the manual slackbuilds for both, and make sure the proper options are installed.

in order for the xbox to see your media, you need to be running a dlna server such as miniDNLA.

Perhaps you have installed the version of my VLC package which I host on connie.slackware.com. I am not allowed to host software which "infringes" on US software patents on that US-baseded server. Therefor that VLC package is unable to ENcode mp3 and aac audio (although it can DEcode those formats just fine).

For a version of my VLC package which can ENcode to mp3 and aac, see http://taper.alienbase.nl/mirrors/pe...ackbuilds/vlc/

The same holds true for my FFMPEG package.

not a slot in replacement but have a look at xbmc.
