Audio glitches when converting from speex in flv/f4v - regression from previous verisons

Version: git-master Keywords: regression speex

Analyzed by developer: no

Description

Summary of the bug:
There're audio glitches when converting from f4v file that was recorded by FMS in source format h264/speex to mp4:h264/aac (or any other audio codec + container (tested with mp3 too).
There was no such problem with previous version of ffmpeg. I'm using ffmpeg from Zeranoe static 32 builds. I was able to to find the period of time when this bug was introduced into these builds. It happened between 2.10.12 N-44998-gdf82454 (this build is working fine) to 5.10.12 N-45080-gd9dfe9a (have glitches from there on). Git's history shows that there was refactoring of audio sampling between these dates.

How to reproduce:
In the attached files you may find sample video that makes problem after convert. You may also find there conversion results of both builds and logs of all attempts.
BTW December builds of Zeranoe fails to convert file at all with error "[graph 0 input from stream 0:1 @ 02217fa0] Invalid sample format '(null)'
Error opening filters!" (Full output in the files)

Thanks for a fast resolution. Was it already committed in to the master?
I downloaded latest Zeranoe build (January 6th N-48513-gcaee85b) and I can't convert same movie yet. I have an error that is similar to what I got when I used December builds:
"Invalid sample format '(null)'
Error opening filters!"

Here's a full output;

If it's a different issue I can open a new ticket.

To decode speex audio you need a FFmpeg binary that was compiled with --enable-libspeex.

comment:7 Changed 5 years ago by mikhailov

Reference to #2085

comment:8 Changed 5 years ago by mikhailov

@cehoyos do you know which exactly commit relate to the bugfix?

comment:9 Changed 5 years ago by cehoyos

This ticket was fixed in f3c9d66, there is not the slightest indication that it is related in any way to ticket #2085: This ticket is about an audio decoding problem, ticket #2085 about a video muxing problem.

Note: See TracTickets for help on using tickets.
