Hi All, I have a live stream that's being received (as an input) with the following parameters:
Input #0, mpegts, from 'http://10.0.0.1/hdmi': Duration: N/A, start: 53055.748056, bitrate: N/A Program 1 Stream #0:0[0x44]: Video: h264 (Main) ([27][0][0][0] / 0x001B), yuv420p, 720x480, 25 fps, 25 tbr, 90k tbn, 180k tbc Stream #0:1[0x45]: Audio: aac (LC) ([15][0][0][0] / 0x000F), 44100 Hz, stereo, fltp, 137 kb/s I'm currently using FFServer with the following settings: <Feed livestream.ffm> File /tmp/livestream.ffm FileMaxSize 50M ACL allow localhost </Feed> <Stream livestream> Feed livestream.ffm Format webm # Video Settings VideoFrameRate 25 VideoSize 720x480 AVOptionVideo flags +global_header # Audio settings AudioCodec libvorbis AudioSampleRate 48000 AVOptionAudio flags +global_header StartSendOnKey </Stream> And I'm calling 'ffmpeg' with the following command: ffmpeg -i http://10.0.0.1/hdmi -c:v libvpx -an -b:v 512K -b:a 128K -cpu-used 4 -threads 8 -s 720x480 http://localhost:8090/livestream.ffm The problem I'm having is that if I change virtually any setting at all, the stream won't work anymore. I'm wanting to have ffmpeg re-encode the stream to a max video bandwidth of 512K and audio bandwidth of 128k in stereo, but if I change these parameters, it won't work. Say I add in ffserver the parameter 'AudioBitRate 128' and 'AudioChannels 2' ffserver then complains with: Wed Oct 25 23:56:23 2017 127.0.0.1 - - [GET] "/livestream.ffm HTTP/1.1" 200 4175 Wed Oct 25 23:56:23 2017 [NULL @ 0x1c00ec0]Failed to read extradata of size 4261 Wed Oct 25 23:56:23 2017 127.0.0.1 - - [POST] "/livestream.ffm HTTP/1.1" 200 4096 And ffmepg dies with: Input #0, mpegts, from 'http://10.0.4.7/hdmi': Duration: N/A, start: 53640.811844, bitrate: N/A Program 1 Stream #0:0[0x44]: Video: h264 (Main) ([27][0][0][0] / 0x001B), yuv420p, 720x480, 25 fps, 25 tbr, 90k tbn, 180k tbc Stream #0:1[0x45]: Audio: aac (LC) ([15][0][0][0] / 0x000F), 44100 Hz, stereo, fltp, 117 kb/s [tcp @ 0x19547c0] Connection to tcp://localhost:8090 failed (Connection refused), trying next address [tcp @ 0x199abe0] Connection to tcp://localhost:8090 failed (Connection refused), trying next address [libvpx @ 0x199a160] v1.3.0 Output #0, ffm, to 'http://localhost:8090/livestream.ffm': Metadata: creation_time : now encoder : Lavf56.25.101 Stream #0:0: Audio: vorbis (libvorbis), 48000 Hz, stereo, fltp, 128 kb/s Metadata: encoder : Lavc56.26.100 libvorbis Stream #0:1: Video: vp8 (libvpx), yuv420p, 720x480, q=-1--1, 64 kb/s, 25 fps, 1000k tbn, 25 tbc Metadata: encoder : Lavc56.26.100 libvpx Stream mapping: Stream #0:1 -> #0:0 (aac (native) -> vorbis (libvorbis)) Stream #0:0 -> #0:1 (h264 (native) -> vp8 (libvpx)) Could not write header for output file #0 (incorrect codec parameters ?): Connection reset by peer What am I missing here? I seem to be able to read the stream properly, but somewhere between ffmpeg and ffserver it's getting lost in translation. Can anyone help out here? What am I missing? Thanks Steve. _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
