avcodec/mp3 : fix skipping zeros
30 septembre 2015, par wm4avcodec/mp3 : fix skipping zeros
Commits 43bc5cf9 and c5371f77 add code for skipping initial zeros in mp3
packets. This code forgot to report to the user that data was skipped at
all.Since audio codecs allow partial packet decoding, the user application
has to rely on the return value. It will remove the data reported as
consumed by the decoder, and feed it to the decoder again. This resulted
in the mp3 frame after the zero region to be decoded over and over
again, until the zero region was finally skipped by the application.Fix this by including the amount of skipped bytes to the number of
consumed bytes returned by the decode call.Fixes trac ticket #4890.

Could not find tag for codec h264 in stream #0 (mp4)
18 août 2019, par TabsNotSpacesI’ve been using the sickbeard_mp4_converter for a while to convert video files to mp4 by generating a script for ffmpeg. I’m not sure what I changed, but the ffmpeg script it generates no longer works and I’m having trouble debugging it. Can anyone tell from my log what the issue is ? Yes, its supposed to be an mp4 to an mp4, which is typically fine.
I’m at the point where I’m using an mp4 that worked with the same autogenerated script yesterday but it no longer is. I remember updating ffmpeg but downgrading did not resolve the issue, though I may have not downgraded enough.
ffmpeg 4.1.4
