ffmpeg - av_interleaved_write_frame() unknown error when streaming WebM -


i'm following a guide live webm streaming through ffmpeg / ffserver , running interesting error. have tried using directshow webcam source, , existing webm (finite length) video using -vcodec copy. initially, both manage connect ffserver (i can see post 200 oks /feed1.ffm), , maybe send frame or two, ffmpeg crashes av_interleaved_write_frame(): unknown error. (meanwhile, ffserver appears fine.)

this appears unusual variant of error - it's more common get, say, av_interleaved_write_frame(): i/o error (which indicates file corruption). has seen error, , better yet, can tell me how fix it?

ffmpeg commands

  • ffmpeg -re -i univac.webm -vcodec copy -acodec copy -f webm http://[my server]/feed1.ffm
  • ffmpeg -f dshow -i video="[my dshow source]" -f webm http://[my server]/feed1.ffm

ffserver command

ffserver -f ffserver.conf

ffserver.conf

this slight variation in 1 provided in aforementioned guide.

ffserver logs

avserver version 0.8.6-6:0.8.6-1ubuntu2, copyright (c) 2000-2013 libav developers

built on mar 30 2013 gcc 4.7.2

avserver started

[current time] - [get] "/feed1.ffm http/1.1" 200 4149

[current time] - [post] "/feed1.ffm http/1.1" 200 4096

this caused using different versions of ffmpeg , ffserver. try use same version. should work without problem. in addition, use libav or ffmpeg, because not quite compatible each other.

this question has answer here: illegal use of register in indirect addressing 1 answer i writing 8086 assembly program needs compile through tasm v3.1. running error can not seem fix. my data segment has following set purposes of keyboard input: parao label byte maxo db 5 acto db ? datao db 5 dup('$') what trying first character entered, first byte of datao: lea dx, datao mov bl, [dx] however, when attempt compile, error: **error** h5.asm(152) illegal indexing mode line 152 "mov bl, [dx]" any appreciated. if matters, running tasm through dosbox (my laptop running 64-bit win7) google hasn't come helpful answers. can post entirety of code if necessary. pretty sure reason can't use dx register pointer. try instead using [si], [di] or [bx]: lea bx, data0 mov al, [bx]
