Hi, In my lab we do research on speech recognition. Lately we have been transcribing lots of broadcast radio news automatically with our system. A way to present the results that allows many users to view them is to combine the audio track with subtitles (.srt format generated from the speech recognition output). With QuickTime Pro I managed to produce a video starting from a single .png image that is looped as long as necessary to match the length of the audio (thus with a static background). Many movie players then are capable to load and show the subtitle file along with this video. But I want to generate this video with mplayer instead of QuickTime Pro because this process ideally should run on Linux and not on a Mac and it should be possible to easily script it. I've been searching with google to find the correct mplayer options but was unsuccessful. I have been using commands such as mencoder mf://test.png -mf type=png:fps=0.01 -ovc lavc -lavcopts \ vcodec=mpeg4 -ofps 25 -audiofile test.mp3 -of mpeg -oac copy -o test.mp4 and several variants but this is not successful. I also would like to get rid of the fps=0.01 specification because I don't want a 100 sec video but one that is exactly as long as the audio track. The resulting video should also contain all frames from the start to the end and not just a single frame with the instruction to repeat it until the end. I am a newbie here, so I am expressing myself maybe not good enough here - with the video generated by QuickTime Pro I initially had problems of VLC or mplayer not showing the subtitles, until I exported the video as a DV stream (effectively containing all frames - all identical), and then later converted it to mpeg4 to decrease it's size. Can anyone point me to the right options for mplayer? Thanks in advance Patrick
