I'd like to see how an working MP4 with G726 look like and if I can play this sample. Has anyone got an mp4 sample with G726 audio plus any video (H264/Mjpeg/.) that could share with me? I have tried to find a MP4 sample with G726 audio from the internet but was't successful so far. The FOURCC code for the audio is 0圆D730045 (ie "ms" plus the WMP code "0045".Īnyone any idea why I can't play G726 in the MP4 file? I also got the mediaInfor from the MP4 as follows:Ĭomplete name : \pathtomp4\videoaudio.mp4
17514ĭMO WMSpeech Decoder DMO 000A, 000B WMSPDMOD.DLL. 17514ĭMO WMAPro over S/PDIF DMO 0162 WMADMOD.DLL. Here is what I got from WMP Technical Support Information page (only audio codec part):ĪCM Microsoft CCITT G.711 A-Law and u-Law CODEC 0007ĪCM Fraunhofer IIS MPEG Layer-3 Codec (decode only) 0055ĪCM Fraunhofer IIS MPEG Layer-3 Codec (professional) 0055ĭMO WMAudio Decoder DMO 0160, 0161, 0162, 0163 WMADMOD.DLL. I can convert the mp4 file to an AVI file which can be played OK with WMP/VLC/QT without any issue (I did get audio!). MP4 files created by our code with other audio codec were played OK without any problem.
I also tried to install the Sharp G.726 Audio Codec 1.1.0.1, but WMP still plays the MP4 without audio. I tried to install the K-Lite Mega codec pack, but it made no difference. Currently when I play the MP4 with WMP, VLC or QT, I got video, but no audio (G726). The MP4 is created by our code from frame data recorded from a camera. I'm struggling to play G726 in MP4 with WMP and hope someone here could provide some ideas on it.
