Hello. I've been testing ffserver and have noticed it crashes a lot. Sometimes crashed when the stop button is pressed while watching a video on VLC. Today I continued testing it and played a video using ffplay on a remote pc running Win7 and at the end of the video this is the error I received:

I think that doubling the % symbol because you are executing from a bat file will help, ie. img%%1d.bmp That said, I prefer using "-pattern_type glob" so your command would look more like this: ffmpeg.exe -framerate 1/10 -f image2 -pattern_type glob -i 'img*.bmp' temp.avi I hope that

Hi Simon / All - Useful to know about "-nostdin" - I need to spend more time rtfm. However, update on my issue: I'm not sure where the bug lies, but I was incorrect about stdin being the problem. It was a coincidence that PAExec crashed near when "Press [q] to stop..." was output from FFmpeg.

In what way does it depend on the formats? The files are streamed to/from in a nut container. I've managed to fake it on the segmenting side by buffering through a file, i.e. the segmenter writes to disk and then I wait for the segment_list items and start uploading and then remove from disk once

I'm using ffmpeg to segment/concat a 120Mbit/s file in 2 second segments to/from a HTTP server. The problem is that ffmpeg only writes/reads one segment at a time which doesn't fully use all available bandwidth. Each request to/from the server has a limit of 10MB/s. However using 5+ concurrent req
