Description
I'm trying to re-encode a MP4 video with FFMPEG version 3.2.4-1~14.04.york1 (the original video is playable in all Windows players like WMP or MPC):
ffmpeg -re -i /home/clip.mp4 -y -preset ultrafast -crf 35 -c:a aac -threads 2 /home/conv1.mp4
But the converter freezes at the first frame, there are many such identical strings:
frame= 0 fps=0.0 q=0.0 Lsize=
So the output has no video, just an audio track.
And FFProbe says that it seems the video container normally:

Tried converting the video to different formats - still same results, no video.

For future tickets: Don't forget to test current FFmpeg git head and provide both command line and complete, uncut console output of the command line you tested, please don't add ffprobe output, it is useless.

The regression since af1761f7 is a duplicate of ticket #6257 (which seems to have a bad title), the regression since ca6cae73 could be a duplicate of ticket #6138.

See https://trac.ffmpeg.org/ticket/6138#comment:7 . You can use -advanced_editlist=0 to turn off the edit list parsing feature, to make these files pass.
