Hi All:

My box is CentOS6.5, and FS is 1.6.4

When I use H264 as the video codec.

FS report encoding fail as below.

[ERR] avcodec.c:1117 Encoding Error -1

and x264 report

lookahead thread is already stopped

I checked the source code, I found that

when switch_h264_encode encode is invoked first time, it results that context->got_encoded_output is set to 1.

and after that, if switch_h264_encode is invoked again, it will check context->got_encoded_output , and then pass null frame to avcodec_encode_video2 which will stop the lookahead thread because of the null frame.

switch_h264_encode:

if (*got_output) { // Could be more delayed frames

ret = avcodec_encode_video2(avctx, pkt, NULL, got_output);

Is it a bug of mod_av or how can i solve the problem?

Thanks a lot
