> Does MP4 "streaming text format" or 3GPP TS 26.245 Timed Text allow any formatting? No the foggiest idea. Now, if I extract the srt from the output mp4, it shows that it lost all its font formating. In a 2nd attempt, I tried to convert from mkv to mp4, but I failed. ffmpeg -i out.mkv -c:v copy -c:a copy -c:s srt outConverted.mp4 ... Stream mapping: Stream #0:0 -> #0:0 (copy) Stream #0:1 -> #0:1 (copy) Stream #0:2 -> #0:2 (subrip (srt) -> subrip (srt)) Could not write header for output file #0 (incorrect codec parameters ?): Invalid argument So the question being indeed: 1/ does mp4 supports it? (As separated mp4 and srt it does). 2/ does ffmpeg implements it? 2015-05-25 21:16 GMT+02:00 Lou <[email protected]>: > On Mon, 25 May 2015 10:35:50 -0700 > jamie <[email protected]> wrote: > > > Hi, You have to use the Advanced Substation format (*.ass) to control the > > look to that level - can't be done with just an (.srt) to the best of my > > knowledge with the current version of ffmpeg. > > I believe SRT will allow you to set the text color. > > However, the questions here are: > > * Does MP4 "streaming text format" or 3GPP TS 26.245 Timed Text allow > any formatting? > > * If it is supported, does ffmpeg implement it? > > * If yes, does the user's player support it? > > I don't know the answer to any of these questions. > > Also, please avoid top-posing on this mailing list. > _______________________________________________ > ffmpeg-user mailing list > [email protected] > http://ffmpeg.org/mailman/listinfo/ffmpeg-user > _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user
