[FFmpeg-user] HTTP Reconnect not Recovering

[Robert Nagy]

I'm unable to get ffplay/ffmpeg to properly wait and reconnect to a http
stream.

1. ffplay -reconnect 1 -i
http://localhost:8000/file/cir7q2zxh00013l5hh0src1fh.mxf
2. Kill file server
3. Start file server
4. ffplay does not recover

I've also tried with a H264 stream with similar results. Am I doing
something wrong here or misunderstanding the reconnect feature?

Given that I'm getting decoder errors after the 3rd reconnect (before the
file server has started) it looks like the decoder is either getting
incomplete data or just continuing without waiting for the complete data.
Do I need to provide some other flag somewhere?

ffplay -reconnect 1 -i
