[FFmpeg-user] "ffserver" stream has audio but no video after upgrading
Hello Everyone, Good morning. I use FFmpeg in my home surveillance system. Prior to upgrading to recent versions, I am using "*FFmpeg 2.4.3*". I use "ffserver" to stream multiplexed video stream (from network cameras) and audio stream (from desktop PC microphone). Using "*FFmpeg 2.4.3*", I can successfully access the streams. Meaning I can see video from the network camera and hear audio from the common microphone. To illustrate: ffmpeg -i network_camera1_video_stream -i desktop_microphone_audio_stream ---> ffserver ffmpeg -i network_camera2_video_stream -i desktop_microphone_audio_stream ---> ffserver ffmpeg -i network_camera3_video_stream -i desktop_microphone_audio_stream ---> ffserver *CASE 1: Upgrade to FFmpeg 3.0* I decided to upgrade to recent versions of FFmpeg. I tried FFmpeg 3.0. There is no change in "ffserver.conf". In the "ffmpeg" command line, I only added "*-thread_**queue_size 256*" to fix the warnings about increasing the thread queue size. The result is that there are no streams accessible (i.e. no video/audio), though I don't see any issue with the logs. *CASE 2: Upgrade to FFmpeg 2.8.6* I then backtracked and tried "*FFmpeg 2.8.6*". Again, the only difference is the added "*-thread_queue_size 256*" option to fix the warnings. This time, there is audio, but there is no video. The following are the logs for 2.8.6: *ffserver.conf* == HTTPPort 8090 HTTPBindAddress 0.0.0.0 RTSPPort 8554 RTSPBindAddress 0.0.0.0 MaxHTTPConnections 2000 MaxClients 1000 MaxBandwidth 1 File /tmp/828222942.ffm FileMaxSize 500K ACL allow localhost Feed 828222942.ffm AudioBitRate 128 AudioChannels 1 AudioSampleRate 48000 AVOptionAudio flags +global_header NoVideo File /tmp/1663648364.ffm FileMaxSize 500K ACL allow localhost Feed 1663648364.ffm Format mpegts AudioBitRate 128 AudioChannels 1 AudioSampleRate 48000 AVOptionAudio flags +global_header == *# /usr/bin/ffserver -loglevel debug -f ./ffserver.conf* == ffserver version 2.8.6 Copyright (c) 2000-2016 the FFmpeg developers built with gcc 4.7.2 (Sourcery CodeBench Lite 2012.09-62) configuration: --enable-cross-compile --cross-prefix=/home/marc/ENVIRONMENT/bsp/output/host/usr/bin/i686-pc-linux-gnu- --sysroot=/home/marc/ENVIRONMENT/bsp/output/host/usr/i686-buildroot-linux-gnu/sysroot --host-cc=/usr/bin/gcc --arch=i686 --target-os=linux --extra-cflags=-fPIC --enable-static --enable-shared --prefix=/usr --enable-avfilter --disable-doc --enable-gpl --disable-nonfree --enable-ffmpeg --disable-ffplay --enable-ffserver --disable-postproc --enable-swscale --enable-indevs --enable-indev=alsa --enable-outdevs --enable-pthreads --enable-zlib --disable-armv6 --disable-armv6t2 libavutil 54. 31.100 / 54. 31.100 libavcodec 56. 60.100 / 56. 60.100 libavformat56. 40.101 / 56. 40.101 libavdevice56. 4.100 / 56. 4.100 libavfilter 5. 40.101 / 5. 40.101 libswscale 3. 1.101 / 3. 1.101 libswresample 1. 2.101 / 1. 2.101 [ffm @ 0x94c1e00] Format ffm probed with size=2048 and score=101 [NULL @ 0x94c3680] Setting entry with key 'b' to value '128000' [NULL @ 0x94c3680] Setting entry with key 'ac' to value '1' [NULL @ 0x94c3680] Setting entry with key 'ar' to value '48000' [NULL @ 0x94c3680] Setting entry with key 'flags' to value '+global_header' [AVIOContext @ 0x94b8be0] Statistics: 32768 bytes read, 0 seeks [ffm @ 0x94c1e00] Format ffm probed with size=2048 and score=101 [NULL @ 0x94c3680] Setting entry with key 'b' to value '128000' [NULL @ 0x94c3680] Setting entry with key 'ac' to value '1' [NULL @ 0x94c3680] Setting entry with key 'ar' to value '48000' [NULL @ 0x94c3680] Setting entry with key 'flags' to value '+global_header' [AVIOContext @ 0x94b8be0] Statistics: 32768 bytes read, 0 seeks AUDIO INITIALIZING [ffm @ 0x94c8520] Format ffm probed with size=2048 and score=101 [NULL @ 0x94c9da0] Setting entry with key 'b' to value '128000' [NULL @ 0x94c9da0] Setting entry with key 'ac' to value '1' [NULL @ 0x94c9da0] Setting entry with key 'ar' to value '48000' [NULL @ 0x94c9da0] Setting entry with key 'flags' to value '+global_header' writing recommended configuration: b=128000,ac=1,ar=48000,flags=+global_header [AVIOContext @ 0x94b8be0] Statistics: 40960 bytes read, 2 seeks [NULL @ 0x94c9da0] Setting entry with key 'b' to value '128000' [NULL @ 0x94c9da0] Setting entry with key 'flags' to value '0x0040' [NULL @ 0x94c9da0] Setting entry with key 'ar' to value '48000' [NULL @ 0x94c9da0] Setting entry with key 'ac' to value '1' [NULL @ 0x94c9da0] Setting entry with key 'frame_size' to value '1152' [NULL @ 0x94c9da0]

Hi Everyone, Good morning. I would like to follow-up if there are other solutions I do based on the logs and information I have provided? Thanks!
