Media resource could not be decoded, error: Error Code: NS_ERROR_DOM_MEDIA_DECODE_ERR (0x806e0004) Details: virtual mozilla::MediaResult mozilla::FFmpegVideoDecoder<62>::DoDecode(mozilla::MediaRawData*, uint8_t*, int, bool*, mozilla::MediaDataDecoder::DecodedData&): avcodec_send_packet error: Unknown error occurred

i already tried to delete the cookies and cache, but 1 user is still muted for no reason and everyone/everything else works fine, so is there something wrong with the browser ?

i basically got like 2-3 completely different users muted for no reason, but at the moment i can only remember 1 of them and noone else has been added to the bug list ever since... and it basically happened when the Firefox itself got really low on memory again and started to display that red crash button. and even then, many different users crashed, but some did not even get the sound back anymore, while others did with no issue....

ps. i also found the other streamer now and both of them i was following, so that is also really weird, plus i havent noticed anyone else getting muted again, so maybe its just the ones that i followed ??? (and during the red crash button then)

(specs are probably in the other "Firefox memory fail" thread)

Hi,

Audio is not working in my firefox browser. i am using Windows 10 laptop. tried all troubleshooting options, uninstalled and reinstalled firefox application . But the issue exists. Can anyone help to fix this audio issue in my browser?

When I try and access a streaming service (ABC iView) I see the start of the video as a single image which is still and doesn't play - audio is working fine - what is the issue?
