Hello! I get the same error when sending vocal messages, ffmpeg can’t overwrite a temporary file.

Here is the log: WRN File '/tmp/mautrix_ffmpeg_1992569585/input.m4a' already exists. Overwrite? [y/N] Not overwriting - exiting

I asked tulir, creator of mautrix bridges, about it, here is his answer:

tulir fluffychat doesn't send voice messages correctly actually that error shouldn't happen if fluffy just sent normal audio files, which makes me think fluffy is actively violating the spec rather than just sending audio files

I think there is a link with issue #926

For me it has worked normally for a long time, but since about a month it does not anymore and it’s very anoying. I tried rolling back to previous versions of Fluffychat but it didn’t fixed anything.

You can ask if you need anymore information or log.

I have the same Problem. Is there a workaround? bridged speech notes work with Element and Schildi Chat, but i prefer Fluffy Chat

I can confirm, it's because fluffy chat uses video/mp4 as mimetype instead of audio/ogg. mautrix-whatsapp returns "⚠ Your message was not bridged: unsupported media type "video/mp4" in audio message"

So solving #926 would be the solution to this problem too.
