ffdshow tryouts project: Discussion & Development

Here is a test build (32 bits)

Configuration : enable subtitles, and enable vobsub (cosmetic to be done). Indeed, the scaler that is used is the same as vobsubs. Then play a m2ts file (I made all my tests with graphstudio)

Status :

• Working with m2ts files (from blurays). Tried with MPC splitter
• BR subs in MKV : not tested, a mediatype should probably be added if this does not work
• Subtitles are positioned correctly even if the resize filter is enabled
• The subtitles should also be placed correctly if you enabled zooming
• Zooming with smooting modes that are working : none, gaussian swscaler (full does not work yet, didn't tried the others)
• The subtitles edge look a little yellow, don't know why yet
• Subtitles with overlapping timestamps should be handled correctly
• Performances should be checked : I used SSE optimizations but the PGS parser may require some adjustements

It's not working here in MPC-HC. No subtitles show.

Edit: Is ffdshow_rev3254_20100207_dbt_bitstream_trial_beta2.exe the correct file?

Sorry, wrong link (I was really tired)

Here is the right one :

Thx you

I'll try it today of course

Can someone commit an update for Czech translation. It's hanging on the tracker for almost a month already and no one seems to bother with it even though the patches around it were already applied.

[albain]

I have adapted the approximative scaler to RGB32 for PGS subtitles.

There are still the bilinear and the full scaler to be adpated now.

I'll test another build when all the scalers will work and with the modifications on the interface

Hi albain,
nice progress!

I've tested briefly, I think there are some colorspace issues with YV12, because It didn't look so good combined with DXVA.

It also crashed once when I changed the subtitle stream in the middle of playback.

I'll have time to take a look at the code later this week.

Thanks!

Commited at r3275.

Hi Tal,

I have committed my changes : all the scalers work except bilinear, don't know why, it is not very important

I have renamed the Subtitles > Vobsub section to "BluRay & DVD"

The color problem you got may be due to an inversion of red and blue channels. There was a bug in the existing code, I fixed it. Maybe this is the cause.

You can grab the last revision if you want to work on it.

I haven't work yet on the subtitles stream switching issue (crash).

Thanks

Can someone update the ICL project files? I've done it for my needs but it should be in the SVN. BTW, albain I noticed that you removed the post build event of registering ffdshow.ax. I hope you keep it that way.

albain, please do not keep it that way.

[XhmikosR]

I knew you wouldn't agree, maybe I shouldn't mention it and no one would notice it... who knows

This was not wanted. I always remove that option for my personal use

I have issues with ffmpeg-mt decoding. The file loads in MPC-HC but the file does not play. All I get is a still black frame. The time elapsed stays the same but I can seek around but the frame is always a still black frame. Libavcodec works OK.

I haven't tested it much due to lack of time but this was something I encountered on the first test with multiple simultaneous subs.

Please post your sample then, I don't have any simultaneous subs

@Tal : I didn't experience crash while switching subtitle streams

I can't seem to get a screenshot of what it's supposed to look like but the dialog is supposed to be at the bottom and the kanji title translation is supposed to be at the top.

Edit: ffmpeg-mt seems to be working in the recent build on xvidvideo.ru.

[David602]

Any plans to add FFDSHOW DXVA support for the Clarksdale architecture? Intel created an SDK to make it easier to work with.

[Sebastiii]

Hi,

I have tested subs in DXVA and also in non DXVA with FFDshow of course lol.

I have strange issue :
I use MPC Mpeg Splitter for .m2ts and MPC Matroska Filter for MKV.

For .m2ts :
The graph connect subtitle output from MPC to Text input FFDshow for m2ts with sub inside and also m2ts with no sub inside (i can verify if sub is here with mediainfo) -> but even with m2ts with sub, i can't see it and selected it (even if i seek the movie)

For .mkv :
FFDshow find sub (.srt or other and play it) i can select sub if we have multi file in directory but the issue that it didn't choose always the right sub) for example, i have a sample.mkv with sub inside and other files with sample2.srt toto.srt etc. -> FFDshow select sample2.srt (in this case). (DirectVobsub select only the match name).
Also when right clic on FFDshow didn't show embedded sub and to make it appear, i must seek in video and it appear.

I hope that i can explain good lol.

It's a great work but for now i can't see subs arf !.

Ps : To try to select, enable/disable sub, i use MRCremoteplus, i can map this option with MCE remote, i can manage enable/disable but no selection of sub, i think that i didn't find where is configured, i've try to find to show it in OSD screen but no success lol.

Also i've try with in mediaportal but, i think it was necessary to put an remote API like MCERemoteplus in mediaportal code to make it work.

Cheers,
Seb.

I have try the sample and i have put it in my test directory with many .srt.

FFDshow select sample2.srt (not cool lol) and i can't see embedded sub .

Hi again lol,


So this is log from debugview if it help

Trace from .m2ts with mutliple sub inside (no selection possible and no sub renderer)
M2TS_0001_Multisubs(not working even seek)

Trace from .mkv with mutliple sub inside, sub only appear when i seek the video (when i go to right clic on FFDshow icon, i have the choice after but didn't render too.
MKV_[Eng-Jap] Art Of Fighting OVA (Eng-Esp sub)(Seek)

Trace from .mkv with only 1 sub inside, sub only appear when i seek the video and disable and enable sub (when i go to right clic on FFDshow icon), i have the choice after but didn't render too.
MKV_sample(Appear after many seek and disable and enable sub)

I know that it for Bluray but i made all test posible to see why.

Anther issue also is if the OSD is enable, when i play [Eng-Jap] Art Of Fighting OVA (Eng-Esp sub) Graphstudio crash.

Cheers,
Seb.

Convolver filter question: I tried the convolver filter inside ffdshow with impulse files here http://sjeng.org/foobar2000.html . Specifically I tried the Urei 1178 Impulse file inside the tube amps package. With Auto Adjust enabled I have very low volume compared to nearly the same level of volume as original file with foobar convolver component. When I disabled Auto Adjust I have to set the Level bar to maximum to have nearly normal volume. Is this by design?

Tested with ffdshow 3277 x86 build on xvidvideo.ru and foobar 1.0 with latest convolver component. Source audio spec: 48000Hz, 16bit, Stereo; the Urei impulse file: 44100Hz, 16bit, mono. I have tried to resample my source to 44100Hz before sending it over the convolver filter inside ffdshow, same thing happens.
