ffmpegX to PSP conversion creates unreadable, Zero KB files

[Peter Sarkisian]

Hello,

I'm trying to use ffmpegX to convert various video clips for viewing on a PSP. The program appears to run perfectly, importing and converting all formats I've tried (MPEG2, MPEG1, MPEG4, MOV etc., etc., etc.!)... however the conversion process takes only about a second to complete, and the resulting files are all zero KB. I cant open any of them in quicktime, and when I transfer them to the PSP they show up in the movies list but don't play, giving me a corrupted file message instead.

I've tried using another program on my old PC but that doesn't work it either. How hard can it be??!!

Can anyone help?

Thanks a mill'

Thought I had it figured out after searching another thread, which points to a problem with audio. The files I'm trying to convert don't have audio, so after unchecking the "encode audio" button under the audio tab, it converted a file that Quicktime can open, but the PSP now says it's unreadable, so my problem continues under a different guise.

Aslo, theres no Thumbnail image for the file on my PSP, just a generic graphic.

Thanks for any insights..

I cant seem to convert anything that works. The PSP (XviD) setting wont play on the PSP, and the PSP H264 just gives me a failed message when converting. Here are several post-conversion info messages:

- "Info" message following unplayable PSP XviD MP4 conversion (note, this file plays fine using quicktime, but wont play on the PSP:

"... 1 video MPEG-4 Unknown Profile(0), 15.081 secs, 0 kbps, 320x240 @ 29.97 fps"


- "Info" message following PSP H264 Failed conversion:

"Could not write header for output file #0 (incorrect codec parameters ?)"

Perhaps the PSP wants movie clips to have a video track and an audio track to see them as valid movie files?
The PSP H.264 preset in ffmpegX surely wants an audio track; it says so in the log:

[psp @ 0x4701fc]PSP mode need one video and one audio stream
Could not write header for output file #0 (incorrect codec parameters ?)

Maybe you could add a silent audio track [1] to your source file, maybe then ffmpegX converts fine and the output will be readable by the PSP?

[1] You could use Audacity to generate silence for the same length as the video, save it as WAV, and add that to your video.

Thanks, Ill try that.

Thanks Case - that fixed the problem! Lesson learned: the PSP needs audio - and that audio needs to be properly mapped.

Thanks again!
