this sample has been created with mkvmerge, which is known to not create correct native asp mkv files ___from avi or raw sources___ my tests have shown that mkvmerge creates correct native asp from .mp4 sources xvid_encraw and the haali mkv merger create correct native asp samples, but videolan also...

i have been doing a comparison of various avc decoders/players available here

in mplayer its possible to measure the maximum decoding speed (without displaying any video) via the -vo null -benchmark option

is there something similar in videolan?

this empire.mp4 files is not a correct .mp4 file

this has been discussed here:

The DJ, there seems to be a small problem described here:

does vlc take things like subtitle positioning into account? Yes: settings>preferences>input/codecs>other codecs>subtitles>subtitles justification> change position to your preferable position. no, i meant the positioning of the subs stored in .mp4 (yeah when creating a timed text stream in mp4 you ...

Should be working now btw in the development tree (since today) great stuff, thx a lot! i have some questions: - does vlc support any of the more advanced features, like color, font, italic aso...? you can find a list of what all is possible here - does vlc support timed text in .3gp? i have the 3g...

apple's quicktime only supports timed text placed in .3gp! yeah, .3gp is nearly the same as .mp4, but still they dont support timed text in .mp4 why? dunno. they also support 6channel aac only in .mov, but not in .mp4, altough mov and mp4 is also very similar using the same standard in both 3gpp and...

3gpp timed text and mpeg-4 timed text are identical. the mpeg-4 standard document basically only refers to the 3gpp one from what i remember

just for completeness: vlc already has some incompliant and unfinished support for CREATING mpeg-4 times text streams if i recall it correctly afaik these vlc created streams already also play in vlc so what would be needed would be to adopt the already existing implementation (written by fenrir afa...

mode2form2 (as used by "xcd") is nothing really fancy and used for example in vcd

after all getting 800mb on a 700mb disc is a nice thing

very important:

make sure that you use the uptodate libavcodec cvs source

...this version of VLC requires ffmpeg 0.4.9-pre1 or later. ffmpeg's last stable release 0.4.8 will not work.

thats what i meant...
0.4.9-pre1 is far to outdated

very important:

make sure that you use the uptodate libavcodec cvs source when compiling, as when using old versions you will get a very weak avc/h.264 decoding support

use search

afaik fenrir already implemented support for dvd vobsubs placed in .mp4 (as done in nero recode2)

afaik vlc currently doesnt produce 100% spec compliant .mp4 files (dunno about mpg) when used for muxing raw h.264 streams you can also try the mp4creator tool from the mpeg4ip project on sourceforge for muxing raw h.264 streams into .mp4 atm it seems as if most commercial h.264 developers place h.2...

for me videolan (one of the latest nightly builds) doesnt show an error when i try to play .mp4 files with mpeg-4 part17 subs (as you pointed to), but it simply doesnt display the text (altough the subs are choosable in the vlc menu) afaik fen once worked on implementing mpeg-4 timed text to vlc but...

i saw that your description "envivio"! how did you create your .mp4 file? afaik the tools from envivio are not totally spec compliant
