The VideoLAN Forums

I'm trying to figure out if it's possible to use VLC for MKV to TS remuxing with the MKV containing a h264 video and AC3 or DTS audio.

Basically what I need is to change the container from MKV to TS to be able to play the files on the new TVIX 4100/5100 media player. It supports h264 fully, it's just the mkv container that it doesn't support.

I've tried to Stream/Save the MKV into a TS, trying out different options (without transcoding), but I always end up with a ts file with the audio but no video. The file size match however (i.e the ts file is basically the same size as the mkv file).

Could I get a hint on how to properly do this, if possible?

Thanks in advance.

Paste your command line.

Thanks for the quick reply.

I'm not using the command line directly, but the MRL is:

:sout=#duplicate{dst=std{access=file,mux=ts,dst="test.ts"}}

also tried with "Select all elementary streams":

:sout=#duplicate{dst=std{access=file,mux=ts,dst="test.ts"}} :sout-all

and if you transcode ?

Even if my purpose isn't to transcode, I did try this and then there is video. However the resulting video is always very blocky and there's a lot of color bleeding (some parts are even solid colors, like green).

I tried different variants, one was for example:
I did also try setting fps= manually just in case, no difference.

I realize now that the video bitrate when transcoding was quite low, since it was a 720p resolution video. That might have counted for the blockyness, but not for the color issues.

In any case, any ideas on why a direct remux does not work?

@ j-b: As a straight copy (MKV to TS) I get this error

packetizer_h264 warning: waiting for SPS/PPS

This would be a MPEG TS error for h.264

The rest of the reporting seems correct.

I thought this was fixed. The DJ did it, as I recall! Deja Vu, I know I have been here before.

@DJ: Well, I have not read and understand the packetizers things in VLC yet.

What is the output of vlc -vvv, btw ?

You want me to do it again? I just cleaned up and put everything away! Ask The DJ, perhaps he will remember as it was during the tests for 0.8.6

Should I do something more here, like submitting some logs?

Would really be cool if this could work

Nope that is fine. I know that some changes were made on the trunk version too.

Should I try with a trunk version or are you planning on changing things further?

I tried to do this with today's (24th of may) trunk, but I'm having problems even saving the file.

Select Convert/Save:


Select the file I want to convert and then Convert in the Convert/Save drop down box:


Tick the file checkbox and then blick on Browse. Here when I enter a filename to save to I get the following:


I tried to enter a filename directly (without browsing), but nothing really happens when I press Convert/Save in the second image. It just starts to play the file.

Thanks in advance.

Phunge have you gotten anywhere with this? I'm looking to get this done as well for my set top but there is no info anywhere on a working system, unless I transcode the AC3 audio to AAC and then remux it.... but that I hope to skip.

ok. Sorry, I haven't seen that thread. The new GUI transcoding is not ready.
Use the old GUI, an old VLC, or the command line.

j-b, so we need the newest trunk to do this transcoding? Or how old of a version do we need to try? CLI would be ideal for me... but I am not very familiar with the VLC architecture.

Well, you shouldn't need a new one, but well, this is a bit unsure.
However you can launch the old GUI with the nighlties with the -Iwx swicth

Interesting.

J-B, I tried the latest nightly with the old GUI, and it indeed remuxed straight from MKV but it broke the video, I have audio but no video, any way to rectify this?

What is the video codec used ?

h264 (x264)

Well, what are the messages ?

This is the call line I'm using with latest VLC nightly + -Iwx switch for the old GUI:

:sout=#duplicate{dst=std{access=file,mux=ts,dst="c:\ooo.ts"}} :sout-all

It encodes to a video ooo.ts, which has audio, but no video, however it does have a source height, width defined, FPS defined etc, but nothing is rendered. It's just black.. is there a way to find out how to fix a TS file or edit a TS file?

It also recognizes that the video codec in the .ts file is H264... but again, no video?

Excellent! Thanks DJ! I'll keep an eye on that... this will make my life so much easier if it works!
