mp4 not generated for some rebuilds

[akhtarkamal1-ed]

Hello

For new recordings of short duration the mp4 is created.

Did a Rebuild on an existing BBB recording and the mp4 was not generated.

Looked into /var/log/bigbluebutton/download/meetingid.log

Looked liked the log had what FFmpeg was trying to do when converting the recording and here is the error at the end of the log.

bbb_version: 2.1.0
Traceback (most recent call last):
File "/usr/local/bigbluebutton/core/scripts/post_publish/download.py", line 288, in
main()
File "/usr/local/bigbluebutton/core/scripts/post_publish/download.py", line 267, in main
dictionary, length, dims = prepare(bbb_version)
File "/usr/local/bigbluebutton/core/scripts/post_publish/download.py", line 183, in prepare
dictionary, length = extract_timings(bbb_version)
File "/usr/local/bigbluebutton/core/scripts/post_publish/download.py", line 57, in extract_timings
temp = float(out_times[len(out_times) - 1])
ValueError: could not convert string to float:

Would appreciate if you could point in the right direction.

You can fix this problem with this patch:

diff --git a/src/download.py b/src/download.py

             total_length = temp

or change:
temp = float(out_times[len(out_times) - 1])

with:

try:
      temp = float(out_times[len(out_times) - 1])
 except:
     continue
