ffmpeg mux problem

[hippy2000]

Hi

I am trying to combine a video and audio stream from youtube with ffmpeg on a linux (kubuntu) box. I run the command

"ffmpeg -i _mediumDarktable_Equalizer_module -i Darktable_Equalizer_module_hd1080.mp4 -vcodec copy -acodec copy darktablefinal.mp4"

but all I get is a small file that only has the audio. Have tried it with the 720 video stream and same result. Terminal output is listed below.

Anyone have any ideas? Am I missing a library or something?

Cheers

[Baldrick]

The video seems a bit different. Have you converted them yourself with exact same settings?

You can also try join with mp4box.

[Selur]

have you tried adding '-map 0:1' and '-map 1:0'

[hippy2000]

tried this command (I presume that is the right way to use '-map 0:1' and '-map 1:0' ?)

ffmpeg -i _mediumDarktable_Equalizer_module -i Darktable_Equalizer_module_hd1080.mp4 -vcodec copy -acodec copy -map 0:1-map 1:0 darktablefinal.mp4

and it gave the error

"Unable to find a suitable output format for '1:0'"

Video file is as downloaded, nothing has been changed with it.

[Selur]

there need to be a space, also I would rearrange the parameters

ffmpeg -i _mediumDarktable_Equalizer_module -i Darktable_Equalizer_module_hd1080.mp4 -map 0:1 -map 1:0 -vcodec copy -acodec copy darktablefinal.mp4

Video file is as downloaded, nothing has been changed with it.

You downloaded audio&video separately?

[hippy2000]

Yep, realised the need for a space as soon as I commented haha

Using the above command I get the error

"Could not find input stream #0.1"

[Selur]

try:

ffmpeg -i _mediumDarktable_Equalizer_module -i Darktable_Equalizer_module_hd1080.mp4 -map 0:0 -map 1:0 -vcodec copy -acodec copy darktablefinal.mp4

[hippy2000]

Not sure if that was the whole command you posted? It gives the error "Missing argument for option 'vcode'"

[Selur]

fixed,..

[hippy2000]

thanks - now I get the error "Codec type mismatch for mapping #0.0 -> #0.0".

Full terminal output is as follows -

rob-carly@rob-carly-P5KR:~/Downloads$ ffmpeg -i _mediumDarktable_Equalizer_module -i Darktable_Equalizer_module_hd1080.mp4 -map 0:0 -map 1:0 -vcodec copy -acodec copy darktablefinal.mp4

[hippy2000]

Changing the command so the video file is first

"ffmpeg -i Darktable_Equalizer_module_hd1080.mp4 -i _mediumDarktable_Equalizer_module -map 0:0 -map 1:0 -vcodec copy -acodec copy darktablefinal.mp4"

doesn't throw an error but it doesn't create a file with any video either, just an audio file.

[Selur]

as a side note:
since audio&video length differ by 20 seconds you output will be asynchronous.
Why did you download audio and video separately?
---
Strange, just tried:

ffmpeg -i test.264 -i test.aac -vcodec copy -acodec copy -map 0:0 -map 1:0 "test.mp4"

and the output is a file with audio&video
and according to your the ffmpeg output you posted both audio&video get copied.

Have you tried playback with ffplay?
What does

ffmpeg -i darktablefinal.mp4

output?

btw. to make your posts more readable: use code- and/or quote-tags

[hippy2000]

as far as I can tell, youtube 1080 clips are seperate video and audio clips now - would be very happy to proved wrong on this as it means I wouldn't have to try and mux them! (clip is at https://www.youtube.com/watch?v=zzVXK4eAM5E&list=PLmvlUro_Up1NBX7VK8UUuyWo1B468zEA0&index=16)

Have only tried playback with VLC - the output file is very small as well - 15 meg when the original video file is 177 meg.

running

ffmpeg -i darktablefinal.mp4

gives

using 'DownloadHelper' inside Firefox I can download a normal mp4 with audio and video in it,...

-> you might want to switch you download method,..

----

Also as a general note:
Do not use ffmpeg for mp4 (or mkv) multiplexing use MP4Box or L-SMASH (or mkvmerge in case of mkv files) for multiplexing.
Only use ffmpeg for multiplexing (mp4/mkv files) if:
a. you only use something that is libav based for playback
b. you can't avoid it since you are doing a live capture (in that case if possible, the output should be remuxed with NMP4Box/..)

[hippy2000]

Yes, I think that is the 720p version not the 1080p version.

YouTube uses Dynamic Adaptive Streaming over HTTP (DASH) for delivering videos and along with that, it serves the audio and video in two separate streams for some resolutions/formats. For instance, resolutions like 1080p and 480p are available only with separate audio and video streams. (from http://www.webupd8.org/2014/02/video-downloader-youtube-dl-gets.html)

I can grab the 720 version as well using flashgot for firefox, now I'm just kind of puzzled as to why I cant grab the 1080p video and audio and mux it back together

[Selur]

Ah, didn't know the switched to DASH for 1080p clips.

[hippy2000]

What command do I need to feed to MP4Box to mux these two files?

[Selur]

mp4box -add "path to video" -add "path to output" -new "path to output.mp4"

[hippy2000]

mp4box -add Darktable_Equalizer_module_hd1080.mp4 -add _mediumDarktable_Equalizer_module -new darktable.mp4

gives the output

mp4box: command not found

Not having much luck!!

[hippy2000]

Actually, think I will stick with the 720p clip - thanks for all your help Selur

[Selur]

depending on the distribution it might be MP4Box instead of mp4box,..

[hippy2000]

BINGO!! Yup - that was it (not sure why I didn't check that, it's late at night here in Australia)

Files combined ok using the following command.

MP4Box -add Darktable_Equalizer_module_hd1080.mp4 -add _mediumDarktable_Equalizer_module.aac -new darktable.mp4

Again, many thanks, much appreciated

[Baldrick]

No problem.

Hello,

Im new to all this so here goes:

Im using ffmpeg to convert mkv to mp4 for personal use. Im trying to take my son favorite movies for use on his dlna player. The dlna server is an Iomega personal Cloud running Twonky 7.2.6-2. The player is a LG BP620c latest update applied. The player can't pause, fast forward, rewind mp4. The ones I have got from friends created with mp4box I think, do. The ones I create not at all but they do play. Here is my batch file
