gr_satellites on ogg file never finishes #428

Closed kng closed 1 year ago

kng commented 1 year ago

I stumbled on some ogg files that would never complete and exit when I processed a bunch of observations. The audio from this observation run with gr_satellites 53385 --wavfile satnogs_6857031_2022-12-10T09-43-12.ogg. But converting it to wav with sox makes it run to completion and exit. sox satnogs_6857031_2022-12-10T09-43-12.ogg satnogs_6857031_2022-12-10T09-43-12.wav gr_satellites 53385 --wavfile satnogs_6857031_2022-12-10T09-43-12.wav This points to libsndfile or something else ? Tried running with --dump_path and the files didn't continue to grow. Tested with gr_satellites version v5.2.0-git and v5.1.0-git

Hi, I have been able to reproduce this bug with a flowgraph that only has a Wav File Source followed by a Null Sink: test_ogg.grc.zip This flowgraph doesn't terminate either.

So this seems like a GNU Radio bug. Maybe this particular OGG file is slightly malformed or has some other weirdness that makes the Wav File Source block never return WORK_DONE (which is what would trigger the flowgraph to terminate). With other OGG files, gr-satellites does terminate properly, so I guess this simple test flowgraph also would terminate.

I suggest you open up a bug report for GNU Radio, since there is probably not much that can be done in gr-satellites to fix this.
