Re: [Commited] [Core] SSA burn-in support

Thanks sneaker,

I've added these samples to the Trac items most likely to be related:
* SSA: Strange shadowing on some descender-letters (j,p,q)
* SSA: Kanji sometimes renders as squares

Now I just need to find some time to fix them...

Re: Concatenate overlapping UTF-8 subtitles

If I recall correctly, the subtitle pipeline isn't synchronized as aggressively as the video/audio pipelines. I think I remember running into some code that just assumed that the subtitles for a given frame were decoded by the time that the appropriate video frame rolls around. That is, it assumes t...

Concatenate overlapping UTF-8 subtitles

This topic is moved from the ReviewBoard system. https://reviews.handbrake.fr/reviewboard.fcgi/r/50/ Each sample in an MPEG4 text track fixes the displayed text for the duration of the sample. I think a good way to handle this is to treat each line in the source srt/ssa track as specifying two even...

[Fixed] Unusual MP4 playback in QuickTime after r3839

Already started discussing this with John, but I figured others might be interested as well. At exactly r3839, one of my test videos encodes to an MP4 that QuickTime has a lot of trouble playing. Associated commit is: * Add parameter parsing and b-frame support to ffmpeg mpeg-4 encoder Notes: * MKV...

Glad to hear it can be reverted for power users. But the gray might make us look boring for new users. Would be better to have lively-looking brand instead of a dull one.

Re: Interested in burn-in of Mpeg2 PS subtitles

Sounds like you want to burn SRT subtitles. There is already support for external SRT import, but not SRT burn-in. To do SRT burn-in (which I think is a Trac enhancement request), you would need to either (1) convert SRT to SSA and let the SSA burn-in logic do the heavy lifting. Or you might want to...

the subtitles do not show up completely in the finished video Could you be more specific? Ideally, could you provide screencaps of (1) a frame from the original source file that displays a subtitle and (2) approximately the same frame in the HandBrake output file that shows the incorrectly rendered...

Re: Burned Subtitle Font Size

We only generate TTXT tracks when soft subbing to MP4 files. If you want to boost the size of SSA hardsubs, you need to feed in a different parameter to: > ass_set_font_scale( pv->renderer, 1.0 ); This is in decssasub.c. Since this isn't a personally useful feature for me, I welcome other adventurer...

Re: [Patch] [Core] Simultaneous subtitle support

Reran some of my input files on this change and saw a lot of lag in the subtitle syncing (over 1000ms). Did some investigation and traced the problem to a bug in the 'sub->sequence > cur->sequence' logic. Subtitle lag times are now around 20-40ms on average. Will be hammering on this changelist with...

Re: [Patch] [Core] Simultaneous subtitle support

Since I have received no additional comments, I will be committing this on Wednesday. This will fix the most glaring SSA issue at present.

Re: [Commited] [Core] SSA burn-in support

In case anyone is wondering, I'm still alive. I am, however, highly distracted.

Signed myself up to do an iPhone project for a client on top of my full-time job, and there's not much time left on the side for HandBrake. Probably won't see much out of me for several months. :(

Soft VOBSUB subtitles (i.e. DVD subtitles) are now supported in MP4. However most players (i.e. iDevices, iTunes, QuickTime) do not recognize them. VLC does.

Who's taking bets on the first bug that will come up in a forum every week for the next year? Think 0.9.4 6ch AAC, VC1, FAS, etc. If we get more new anime users, I'm betting the SSA tickets will keep coming up. Still some kinks that need to be worked out there. For all other users?

Ho boy... Now with 0.9.5 out the door, there'll be a flood of people banging on the new SSA support.

For new users that want to report SSA issues, please check the Trac to see whether the problem you are seeing is already known. All SSA-related tickets are prefixed with "SSA:"
