Sync and Encoding audio: AAC and muxing
by Nicolas Hesler 10 May '08

10 May '08

Up until recently, I've used mencoder to encode and mux MPEG-2. Now I've begun trying to encode h.264 with AAC in AVI and then remux with mp4box. There are a couple of reasons behind my not wanting to mux with lavf in mencoder: - all of the reasons outlined on this list and in the docs (including b frames problem) - to be able to remux for bluray (because, as I understand it, I'd have to remux anyway) I'm fine with the whole process except for audio encoding. I think there is something fundamental that I don't understand about encoding audio or the way that audio is muxed into a stream. I've hit a road block in understanding how AAC is encoded and how it is synced in a stream. In all of my tests, I can't seem to get AAC audio to match the exact length of the video it is paired with. Here is an example: ** Note that all of my attempts are based on uncompressed avi files or wav files and/or raw audio/video coming from a Framesserver. I've got a video source with 305 frames with audio that lasts exactly 305 frames at 24 fps = 12.7083333 seconds. For instance, when I encode using the following command line: mencoder -vf harddup -ovc x264 -x264encopts bitrate=8000 -oac faac -faacopts mpeg=4:object=2:br=224 -channels 2 -srate 48000 -ofps 24 export.avs -o h264.avi I get an h.264 encoded video track with 304 frames (12.667s )(because one frame is skipped) and an audio track that is (12.651s). Why the discrepency in length??? This is 16 ms difference. If I add -mc 0 to the command line, I get back the original 305 frames of video (12.708s), but the audio is still (12.651s). This is a 57 ms difference. Obviously mencoder compensated for the difference in the first example and tried to keep the sync close, but shouldn't I be able to get back the full 305 frames of video along with the full 12.708s of audio? So I did a lot more testing of the audio track. I grabbed the WAV file and encoded it with command line encoders to AAC using ffmpeg, faac, neroaac. In the case of ffmpeg I tried encoding to mp3 as well. In all cases, with no video to worry about, the duration of the encoded audio was always different from the duration of the WAV audio. Why is this? I want to be able to get back the original full length of the video and audio so I don't have to worry about sync issues. Is this possible and under what circumstances?? Would I still have to worry about sync issues if my audio length and video length were the same?? Someone please point me in the right direction. Thanks!

Mencoder usage on the Grid
by Jens Buysse 09 May '08

09 May '08

Hi, I'm new on this mailing list so sorry if I ask a question which has already been answered. My problem is concerning mencoder usage on a resource node on a Grid setup. (http://en.wikipedia.org/wiki/Grid_computing) The idea is to split up a video file in different chunks, send them to different worker nodes to get transcoded en than merged back together. We want to use mencoder for this purpose: splitting, transcoding and merging back together. The problem we encounter is that we do not find a standalone version of the mencoder to send to these nodes... We are not permitted to install software on these resources, though we can send our software to it to work as a standalone version. Now my question: where can I find a downloadable version of mencoder to send to these worker nodes? Or does anybody have a better idea? Kind regards Jens

All video files must have identical fps, resolution, and codec for -ovc copy.
by Vince Gatto 08 May '08

08 May '08

This might be a better post for the developer list, but hopefully someone reading this is geeky enough to help out. So I'm having a problem joining two files using a pretty normal command: mencoder -oac pcm -ovc copy -o joined.mp4 1.mp4 2.mp4 And I'm getting the error "All video files must have identical fps, resolution, and codec for -ovc copy". I've pasted the output below, though I doubt it will be much help. I'm 100% certain that these files have the same fps, resolution and codec. I went so far as to edit the source code to dump some additional data about how mencoder determines that two files are not encoded identically. If you check out mencoder.c, you'll find a section that compares the BITMAPINFOHEADER structures of the files byte-for-byte. As far as the useful information in these structures are concerned, my files are identical, except that they differ in structure size (the first member, biSize). Both of the files in question are using the avc1 codec, and were created by the same ffmpeg command (using libx264). Snooping around the code some more, this extra data in the structure is being added by demux_mov.c and is referred to as "stream header data". Does anyone know what that is or what it is used for? When I modify mencoder to check only the standard parts of BITMAPHEADERINFO, my files join and play without a problem, but I'm worried that I've removed or subverted something I don't really understand and that could cause a problem with other files somehow. And here's the output: MEncoder 1.0rc2-4.0.1 (C) 2000-2007 MPlayer Team CPU: Intel(R) Core(TM)2 Duo CPU T7700 @ 2.40GHz (Family: 6, Model: 15, Stepping: 11) CPUflags: Type: 6 MMX: 1 MMX2: 1 3DNow: 0 3DNow2: 0 SSE: 1 SSE2: 1 Compiled for x86 CPU with extensions: MMX MMX2 SSE SSE2 WARNING: OUTPUT FILE FORMAT IS _AVI_.

Problem with embedding subtitles
by Андреев Максим 07 May '08

07 May '08

I want to embed subtitles in video file to watch it on hardware device, that doesn't support "soft"-subtitles. I try do it 3 days, but i never got any result. I'm using FreeBSD-7.0 and latest mplayer with mencoder from FreeBSD port collection (MPlayer 1.0rc2-4.2.1) I try use "o" option in expand filter config - it's doesn't change anything... Commands i use (now without expand filter config, else add "-vf expand=::::1"): [hint@hint ~/avi]% mencoder -o out.avi -oac lavc -ovc lavc -sub 2.srt -ss 300 -endpos 20 -v 2.avi >> log.txt log.txt: http://paste.org.ru/?94484s Can anyone help me in my problem?

How to avoid A/V synchronisation pb
by Philippe MONROUX 05 May '08

05 May '08

Hi, First I apologize for my poor english. My goal is to x264 2-pass encode one dvd title to one 700 M cd with ogg vorbis sound (not very original...) So in first I need to rip sound to know its size (SoundSize) to have better bitrate calculation (700-SoundSize)*1024^2*8/t/1000 I've read the doc but I'm not sure about my method to avoid A/V synchronisation pbs. Here is my method : 1) rip audio to audio.ogg --> SoundSize --> bitrate 2) pass 1 : mencoder dvd://1 -aid 128 -oac copy -vf [filters] -ovc x264 -x264encopts [options-pass1]turbo=2:pass=1 -o /dev/null 3) pass 2 : mencoder dvd://1 -aid 128 -oac copy -vf [filters] -ovc x264 -x264encopts [options-pass2]:pass=2 -o out.avi 4) mkv creation... My question is about "-ovc copy" in pass-1 and pass-2. Is it a good choice to A/V synchronisation pbs or is there a better choice (I read nosound is not a good choice). Thanks in advance -- Mxph

A/V sync problem when encoding TS stream into MPEG4
by Jiri Hofman 05 May '08

05 May '08

Hello I am experiencing a mencoder problem which appeared during development. I am not sure if this is a duplicate report, however, I will describe it. MEncoder 1.0pre8-4.1.2 encodes TS stream (DVB stream stored by Kaffeine, I can provide a sample if neccessary) prefectly -- A/V sync is just great. After I upgraded to latest version or SVN, A/V sync is lost. When you try to seek in generated AVI, video seeks but sound plays from beginning of file. Do I do anything wrong? This command I use: mencoder "$1".m2t -edl "$1".edl -hr-edl-seek -aspect 16:9 -vf scale=1024:-2 -ovc lavc -oac lavc -channels 2 -lavcopts acodec=ac3:abitrate=128:vcodec=mpeg4:vbitrate=1500:mbd=2 -o "$1".avi Thanks for any help. Best regards, Jiri

Segmentation fault when embedding subtitles and rotating
by Yørn de Jong 05 May '08

05 May '08

Dear developers I have a linux box with an E2160 @ 1.80GHz processor. I Fedora 8 and the mencoder delivered by livna. I'm trying to convert a .mkv file with embedded subtitles to an rotated avi file (my portable player likes it that way) Therefor I wrote a shellscript (with some copy/pasting), which contains the following command: mencoder "${file}" -idx -noodml -ofps 20 \ -font /usr/share/fonts/liberation/ LiberationSans-Bold.ttf -slang und -mc 0 \ -vf scale=320:-2,expand=: 240:::1,crop=320:240,rotate=1 \ -ovc lavc -ffourcc XVID -lavcopts \ vcodec=mpeg4:vbitrate=$ {VBITRATE}:vmax_b_frames=0:vhq \ -sws 9 -srate 44100 -oac mp3lame -lameopts \ cbr:br=128:mode=0 -ss ${ENC_START} -endpos 0:$ {LENGTH}:00 \ -o "${TARGET}${PARTEXT}.avi" As you can see I have hardcoded the subtitle part for now, it's "-font /usr/share/fonts/liberation/LiberationSans-Bold.ttf -slang und -mc 0" ("und" is the name of the language) This causes a segfault. When I remove the rotate part, it works fine. Without the subtitle line and with the rotate, it works fine as well. The error i'm getting when I try to run this as given here is: Pos: 5.3s 126f ( 0%) 108.81fps Trem: 0min 0mb A-V:0.000 [64:128] Skipping frame!

The subtitles are placed where i'd expect them; at the left side. However, the moment the first subtitle appears, some green vertical lines appear, and with the 2nd subtitle the whole movie is green. Then the file ends. I've tried a lot of combinations, one of them using another font, nothing appears to work. Because this case crashes when using two features at the same time (embedding subtitles and rotating a movie) which work fine when used seperately, I think this might be a bug in mencoder. Can someone else please give some feedback on this? I really have no idea how to fix this. Thanks! Yørn de Jong

MEncoder SVN-r26664 interlaced AVCHD decoding issues, sample PF24 M2TS clip available
by Werner Johansson 04 May '08

04 May '08

Hi all, I understand that AVCHD h.264 container support in MPlayer/MEncoder is a recent addition and there seems to be some odd behavior. What I try to accomplish with this setup is to extract true 24p footage for editing from a Canon Vixia HF10 camcorder writing "PF24" AVCHD files in a 1920x1080i container (hard telecined, no flags present). The first odd thing is that the framerate of the video cannot be automatically detected but needs to be forced. I tried setting it to 30000/1001 which would be the logical value, but the video then runs at half speed. I googled some and found others having the same issue and they solved it by using 60000/1001 and got the correct video length. To extract true 24p the detc or filmdint filters seems like a logical choice. I have spotted two issues so far with this setup though: 1: For some reason the clips from the camcorder have 4 initial bad frames with "B picture before any references, skipping" errors, must be an issue with the Canon firmware - why would it create a file with B-frames _first_ in a stand-alone clip? In the end I end up with a video stream that is slightly shorter than the audio. Anyone else seen this? Searching for this error didn't turn up anything AVCHD related, only DVB stuff. 2: There are some blocky artifacts in the decoded video that I can't spot when playing back the original file in Nero8 ShowTime or using the component video terminals on the camcorder itself. Anything that gets lost in demux/decode? Most of the frames look good but some goes slightly bad (not all over the screen, just small portions). In my example clip there's garbage in frame 62 in the resulting 24p file for example. The garbage can be seen when decoding the original file in MPlayer as well, so it's not a result of broken detc or filmdint filtering. If anyone's interested the source clip (of a side-scrolling Nevada desert) it is available here: http://xnk.nu/pf24/00028.mts . It's a fairly short clip (~10 seconds / ~20MB), but it immediately shows any broken 24p conversion! :) This is a sample command line of what I try to do, accompanied by the corresponding output (changing the video filter chain to softskip,detc,scale=960:540,harddup will make the resulting file substantially smaller, suitable as a proxy clip for faster editing) : [root@rofs ~]# mencoder 00028.mts -noaspect -noskip -o 28ffvhuff.avi -fps 60000/1001 -ofps 24000/1001 -oac pcm -ovc lavc -vf softskip,detc,harddup -lavcopts vcodec=ffvhuff MEncoder dev-SVN-r26664-4.1.2 (C) 2000-2008 MPlayer Team CPU: AMD Athlon(tm) 64 Processor 4000+ (Family: 15, Model: 39, Stepping: 1) CPUflags: Type: 15 MMX: 1 MMX2: 1 3DNow: 1 3DNow2: 1 SSE: 1 SSE2: 1 Compiled for x86 CPU with extensions: MMX MMX2 3DNow 3DNowEx SSE SSE2 success: format: 0 data: 0x0 - 0x1434000 TS file format detected.

DTS Passthrough encoding. Lots of dropped frames.
by Mark Hackett 04 May '08

04 May '08

I've got a good rip in vob format that has DTS audio information within it. Encoding with selecting the AC3 information works fine, apart from a couple of skipped frames once every now and then (often only just a couple right at the beginning). However, when I use "-aid 137" to select the DTS audio in mencoder, I get LOTS of dropped frames. Like one or more each second. Sychronisation of the audio stream falls down quickly and the video has a lot of very noticeable skips in it. I can get rid of the skipping (I think, it works on short sections) by using "-mc 0" but that seems to be doubling the size of the file produced and because of that I haven't actually encoded a full movie with it. So anyone got ideas about why this is happening and how to stop it? E.g. is it just that DTS is acting up, or should I use a different container format? Ta.

audio encoding problem from tv

I tried the following command after downloading and compiling 1.0rc2 from mplayerhq (it is a pitty, but I was not able to compile the svn source): mencoder -endpos 60 -o zzz.avi tv://\ -tv driver=v4l2:normid=0:input=1:width=720:height=576:\ alsa:adevice=hw.1:amode=1:immediatemode=0\ -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=1200:autoaspect\ -oac lavc -lavcopts acodec=ac3:abitrate=96:threads=2 -af volnorm\ -vf crop=688:560:16:8,pp=lb -ffourcc XVID The problem is that when trying to skip frames (pressing right/up arrow) during playing the obtained zzz.avi, the sound playback starts over. Furthermore, there is some A/V syncing problem (the sound is in late relative to the video) even without skipping. I have attached the output... no idea what the problem is.
