The VideoLAN Forums

Hi there,
First of all, I would like to thanks every one to keep up with improving this s/w. I starts using it with version 2.2.6 and some features do not work as expected. However, those are work well with the 3.0.4 version.

With this version, I have an issue when trying to add a hardcoded subtitle srt file to my video clip (avi).
I did it with "convert/save" option with Video - H.264 + MP3 (MP4) profile, it only converts the avi to mp4 without hardcoding the subtitle to the file. The size of the file increase about 1 mb from the original file.

The message shows

main info: playlist is empty
main error: subpicture heap full
main error: subpicture heap full
. . .
main error: subpicture heap full

Then, I tried with the "stream" option with the same profile and with selecting subtitle overlay to true, command shows below,

:sout=#transcode{soverlay}:file{dst=C:\\A.srt.mp4,no-overwrite} :no-sout-all :sout-keep

The message log shows as below without any file created.

stream_out_standard error: no mux specified or found by extension
main error: stream chain failed for `transcode{soverlay}:file{dst=C:\\A.srt.mp4,no-overwrite}'
main error: cannot start stream output instance, aborting

This is the first time I try this feature . I try searching for a clue from many posts in the forum but not seem to found the way out. Have I missed something to make it work ? Advices are welcomed. Thank you.

ps. I've tried the other option available i.e. check "stream all element", change the subtitle type from DVB to T.140

See this tutorial on the subject.

Hi Hithchhiker, thanks for the link, unfortunately, this version, 3.0.4, does not provide the same command as the prior version. As you may see in the original message that the command is generate with only the overlay option, it already does not have the "scodec=dvb" option in the generated command.

However, Thanks anyway for suggestion.

I'm try to find the command line to do the stream, yet not find the right one. All suggestions are welcome to try.

Then edit the transcoding profile, disable the "[ ] Keep original video track" option and set appropriate video parameters there ({vcodec=h264,soverlay}). It is all in the tutorial that Hitchhiker has mentioned.

Hi Hithchhiker/mederi, thanks it's work now and sorry for not completely understand the tutorial.
There's more to learn.
