AVC passthrough not working

[DVC]

I have h.264/AVC files that have DVI IMA stereo, 44.1 kHz, 354 kbps audio.

I want to pass-through the AVC and convert the audio to 48kHz ACC.

According to the instructions I should be able to select "pass-through" with Encode video checked. The output should be .MP4 or .MOV with the original video and the converted audio.

Nope.

As soon as I select "pass-through" with Encode video checked the output becomes AVI. The video is not moved through. Moreover, the output fails.

Input #0, mov,mp4,m4a,3gp,3g2,mj2, from '/Users/steve/Desktop/EZ-F1_720p.MOV':
Duration: 00:00:17.6, start: 0.000000, bitrate: 8351 kb/s
Stream #0.0(eng), 29.97 fps(r): Video: h264, yuv420p, 1280x720
Stream #0.1(eng): Audio: 0x1100736d, 44100 Hz, stereo
Output #0, mov, to '/Users/steve/Desktop/EZ-F1_720p.MOV.ff.mp4.aac':
Stream #0.0: Audio: aac, 48000 Hz, stereo, 256 kb/s
Stream mapping:
Stream #0.1 -> #0.0 [sync #0.0]
Unsupported codec (id=0) for input stream #0.1


I've tried all the h.264 options and they all fail the same way.

PS: what is the syntax for encode audio using acc stereo at 256kbps? I'd like to try it in VisualHub using its Pass Through option.

Currently, the pass-through function forces AVI output in ffmpegX. Not sure why.

Stream #0.1(eng): Audio: 0x1100736d, 44100 Hz, stereo
Unsupported codec (id=0) for input stream #0.1

You will need a newer version of ffmpeg to convert '0x1100736d' audio. The version of ffmpeg in current ffmpegX 0.0.9y doesn't support this codec yet.

Not sure. It might be something like:

-acodec aac -ab 256 -ar 48000 -ac 2

Downloaded Y version and it will read the audio codec as long as one recodes AVC to AVC.

Is there a dummy codec that could subsitute for the x264 codec?

Is there a way to have ffmpeg generate its code into a buffer that can be edited before being executed.

Sort of. There are ways to get the command line instruction that ffmpegX creates to pass on to the command line executables that it uses. However, if you decide to edit that, you'll have to go command line from there (i.e. use the Terminal shell).

To get the command line instruction, set ffmpegX to "Open Terminal Window" (in the menu bar). Then also install a third party tool that provides a clipboard history (e.g. PTHPasteboard), sometimes called 'multiple clipboards'. After pressing Encode in ffmpegX, the content of the clipboard before the current one, will have the command line instruction.

Thank you.

Before i try this --- has anybody found a way around the passthrough bug?
