choppy MP4 playback with MP3, ASP and TTXT

[Hobojobo]

Probably not the right place:
I muxed xvid video with a vbr-mp3 audio and subtitle stream into a mp4-container with your great tool.

The playblack is sort of choppy.
How can I make the subtitles show up?

I use:
Media Player Classic
Haali Medi Splitter
ffdshow-20050303

Try different mpeg4 asp decoder filters.

Media Player Classic should be in "VMR9 renderless" mode.
You need to activate the subs by right-clicking on the splitter icon.

Question:
Which icon do you mean. And where can I find it?

The playblack is sort of choppy. try if its choppy with the nero parser filter too

and/or upload the .mp4 files somewhere plz so i can have a look

[bond]

splitted to an own thread

so, Hobojobo, any news on this?

[Hobojobo]

It works.

I uninstalled ffdshow, version 20050328 :o and installed 20050303, I think that has caused the trouble.

Now I have my xvid clips with subs in a mp4 container. Great.
:)

One question:
I can choose srt or ttxt files as format to mux in mp4.
Which way is smarter, in order to produce a 100% conform playable mp4 (for a stand alone device with mp4 support)? ;)

the latest ffdshow version is from 6.4, which you can get here (http://www.aziendeassociate.it/cd.asp?dir=/ffdshow)

Which way is smarter, in order to produce a 100% conform playable mp4it doesnt matter, as mp4box converts srt to ttxt while importing "on the fly"

(for a stand alone device with mp4 support)? none of the existing standalones supports ttxt, only vobsub subs as placed in .mp4 with nero recode

[Hobojobo]

Thanks for the quick answer.

I tried another clip.

After muxing the video into mp4 MPC tells me "MP4: sample_descriptor_index in stsc !=1" and refuse to playback the clip.

gSpot is saying something about "DivX Style "packed bitstream" AVI.

Is there something I can do ?

[bond]

which mp4 muxer did you use?

[Hobojobo]

Yamb 1.2.1 comes along with MP4BOX. That's what I used.

[bond]

make sure you use the latest version of mp4box and haali here
http://haali.cs.msu.ru/mkv/ and
http://www.aziendeassociate.it/cd.asp?dir=/gpac/dev

[Hobojobo]

I updated MP4Box.

I did some tests.
The subtitle file in causing the trouble.
When I untick the subtitles in Yamb, then the mp4 clip is playing fine.

I have tried to mux the subs in srt format directly, then I tried the converted subs, did not make a difference.
I checked the subtitle file in Subtitle Workshop. No errors.

So, somehow the Haali splitter is tripping over the subtitle file.
Interesting.

[bond]

did you upate the haali splitter to the last version?

[Hobojobo]

Yep.

Running on my system:

Haali Medi Splitter 2005/05/03
ffdshow 2005/03/03
MP4Box 2005/05/16

I report back after running some more tests.

And thanks for your help.

[Hobojobo]

I figured out the problem.:D

The splitter does not like italic subtitles.

When I switch the subtitle to plain style, without any tags, the resulting clip with embedded subs is playing fine.

Is it a known limitation?

Great.
I do not really need italic subtitles.
So, I am fine with the workaround.

[Hobojobo]

I am confused.
The subtitle problem came back. :(

I cleaned up my system, new w2k install.
I installed:

ffdshow 20050303
Haali's MediaSplitter 20050503
MPC 6.4.8.4 (directshow video VMR9 renderless)

mp4 clips are playing fine, but the subs are gone.
The icon of the Haali's splitter does not show up in the task bar. show tray icon: yes.
Under filter (in MPC) there is only GPAC Audio and Video Handler.

Does the order in which I install the filters has got to do with it?
Any suggestions?

[bond]

i assume the haali splitter isnt used, but another mp4 splitter, like nero

[Hobojobo]

Strike.

I installed Nero Burning Rom Demo.
After deinstallation Haali's Splitter took the con.;)

Is there a way to force the use of Haali's splitter ?

[bond]

give haali a higher merit as the nero parser with the radlight filter manager:
