Description
Hello.
I have an issue when using "asyncts" audio filter:
ffmpeg command line
ffmpeg -i /tmp/flv.flv -vn -af asyncts=compensate=1 -acodec libfaac -f mpegts -y /tmp/xxx.ts
ffmpeg -i /tmp/flv.flv -vn -af asyncts=compensate=1 -acodec libfaac -f mpegts -y /tmp/xxx.ts

Everything seems to be OK until source runs out of data (EOF and connnection close are tested) or user decides to abort ffmpeg execution (hits ctrl+c).
In both cases ffmpeg does not terminate and starts to produce huge amount of messages (thousands per second) to stderr:
...

until kill or ctrl+c is issued by user.
Problem occurs only when asyncts filter is used:

Is the problem also reproducible with current git head?
comment:3 in reply to: ↑ 1 ; follow-up: ↓ 6 Changed 12 months ago by lvm
Replying to cehoyos:
Is this only reproducible with libfaac or also with the native aac encoder?
ffmpeg -i /tmp/flv.flv -strict -2 -vn -af asyncts=compensate=1 -codec:a aac -f mpegts -y /tmp/xxx.ts
Produce the same.

I've just tried 0.11.1. Same results.

Please test current git head, if you cannot use git, please download a snapshot, see http://ffmpeg.org/download.html

Hi guys, I believe I have the same issue with current git head
Command line :
ffmpeg -v debug -i ./sample.ts -vn -af asyncts=compensate=1 -acodec pcm_s16le -sn -y out.wav
(see full log at the bottom of this comment)
Sample file is available to grab here : http://ey3ball.net/ffmpeg/sample.ts
Result : data is encoded properly, but when ffmpeg exits, it hangs indefinitely (CPU going up to 100% usage)
Looking at what happens in gdb, it seems that ffmpeg is stuck in an infinite loop in poll_filters because the asyncts filter won't return AVERROR_EOF.
I looked at the filter code and the only function that seem to matter for EOS is request_frame.
In this function AVERROR_EOF is detected, however in the event of an EOS, the request_frame function will always return 0 instead of forwarding the EOS to the caller.
I made the very simple following fix :
diff --git a/libavfilter/af_asyncts.c b/libavfilter/af_asyncts.c
index 6322b24..1b10dd4 100644
--- a/libavfilter/af_asyncts.c
+++ b/libavfilter/af_asyncts.c
@@ -131,7 +131,7 @@ static int request_frame(AVFilterLink *link)
nb_samples, NULL, 0, 0);
buf->pts = s->pts;
ff_filter_samples(link, buf);
- return 0;
+ return ret;
}
return ret;
Which seem to work.
As I have no experience whatsoever with the ffmpeg codebase, can someone more familiar with it please confirm this is correct ?
Thank you

No more inputs to read from, finishing.

I'm experiencing the same issue with current git head (N-43520-gd8c3170).
Input is a raw DV stream with 2 audio channels (32kHz PCM).
Uncut commandline and console output:
ffmpeg -i input.dv -vcodec copy -acodec pcm_s16le -filter_complex "asyncts=compensate=1" output.avi

- Keywords libfaac, removed
- Status changed from new to closed
- Resolution set to fixed
Replying to ey3ball:
Command line :
ffmpeg -v debug -i ./sample.ts -vn -af asyncts=compensate=1 -acodec pcm_s16le -sn -y out.wav
The problem is fixed in current git head (and 1.0).
Please note that asyncts is a deprecated filter, aresample is recommended instead.
Note: See
TracTickets for help on using
tickets.
Is this only reproducible with libfaac or also with the native aac encoder?
