WebRTC shows that H264 not supported

[Andriy Buchynskyy]

Hello. I have problem with H264 codec. I can't set remote sdp because I have failure. 

As far as I understand from logs it's not supported. But I don't understand why. 

[000:517] [5422] (webrtcvideoengine.cc:609): SetSendParameters: {codecs: [VideoCodec[97:H264]], extensions: [{uri: urn:ietf:params:rtp-hdrext:sdes:mid, id: 3}, {uri: http://www.webrtc.org/experiments/rtp-hdrext/abs-send-time, id: 4}, {uri: urn:ietf:params:rtp-hdrext:toffset, id: 5}], max_bandwidth_bps: -1, }

[000:517] [5422] (webrtcvideoengine.cc:446): Internally supported codecs: {VideoCodec[0:VP8], VideoCodec[0:red], VideoCodec[0:ulpfec]}

[000:517] [5422] (webrtcvideoengine.cc:553): No video codecs supported.

[000:517] [5423] (channel.cc:853): Failure in SetRemoteContent with action 0

If I'm using VP8 everything works fine. Do you have any ideas how I can fix it? 

Thank you

is it a trace from a browser, or from webrtc "standalone"?

if it's the later, you might have copied it with the default flags which do NOT include H264 support

Thank you for your reply. These logs are from native webrtc code. 

I made application where browser is client side and native webrtc 

is server side. I receive logs from server side - native webrtc.  

[Alexandre GOUAILLARD]

did you compile your native webrtc code with support for H264? it s OFF by default.

Try to enable H264 in the code,by default its VP8. IF you still face quality issue ,use VOIP engine in between.

enable openh264 by set 'rtc_use_h264 = true ffmpeg_branding = "Chrome" ', after this you need modify  third_party/ffmpeg/chromium/config/Chrome/android/arm-neon/libavcodec/parser_list.c and third_party/ffmpeg//chromium/config/Chrome/android/arm-neon/libavcodec/codec_list.c files, add h264 parse, like:

This worked for me at M67 release

Hi, i want to open h264 support in M70 release. And i use the arguments like you do, 'rtc_use_h264 = true ffmpeg_branding = "Chrome" '.
But when i build my project, these error log show up.
Could you please take a look?

Hi

I don't known why this mail was not appeared in my inbox, maybe this reply was too late...

According your log, maybe you need pay attention to third_party/ffmpeg/ffmpeg_generated.gni file, it was not support x86 platform by default
