[Bug 901711] Re: No audio when exporting to MOV with AC3 codec
No there will be none version of MLT in our repository.
Anyway, the 1.4.1 will be out soon (I hope), the 1.5.0 is ready but on stand-by because it misses us a function for an optimal utilisation of GTK3.
And after, we will work on the big 2.0.0 which will come with our own library libopenshot so we won't use MLT after.
I don't know if you should wait or use this one that you have currently. I must said that I don't know when I see all problems that I have with Oneiric and the 0.7.x serie on the French community. If it is working for you,............

Title:
No audio when exporting to MOV with AC3 codec
Status in OpenShot Video Editor:
New
Bug description:
OpenShot 1.4.0
Installed from OpenShot PPA
Ubuntu 11.10 (completely up to date)
FFmpeg compiled from source, version 5:201112071053-git-1
SUMMARY:
An MP3 that was originally encoded with pcm_s16le in FFmpeg plays in
the preview of the OpenShot project, but when OpenShot exports a video
using the ac3 audio codec, the audio from the pcm_s16le encoded MP3
fails to carry over into the newly exported video.
However, when exporting to MOV using pcm_s16le, the audio is re-
encoded without a problem.
WHAT HAPPENED:
I exported a .mov with the following settings:
Video Format: mov
Video Codec: libx264
Bit Rate: 5Mb/s
Audio Codec: ac3
Sample Rate: 44100
No. of Channels: 2
Bit Rate : 128 kb/s
And the video came out fine, but there was NO AUDIO.
WHAT HAPPENED NEXT:
I exported exactly the same project as .mov with these settings:
Video Format: mov
Video Codec: libx264
Bit Rate: 5Mb/s
Audio Codec: pcm_s16le
Sample Rate: 44100
No. of Channels: 2
Bit Rate : 128 kb/s
And the AUDIO WAS OK.
POSSIBLY RELEVANT:
When I recorded the original webcam + audio MKV in ffmpeg, the audio
codec used was pcm_s16le.
