I have a set of 12 old Tarzan movies that are MP4 with AAC audio (hope I'm relating this right). All are on my USB stick and play on all computers in the house but on my LG plasma tv there is no sound. I play MP4 movies all the time from USB on this TV but can't figure out this problem. Please help as my grandson really needs to see these.
Compare the audio of one that works and one that doesn't. See what the difference is. http://www.videohelp.com/software/mediainfo
I don't know how to compare the audio, can you explain? I did check to other MP4 movies I have and the original listings are similar to this. The Tarzan movies are listed as : Audio...AAC/2 channel/44.100khz/128 kbs I watch MP4s all the time and have never experienced this. Thanks
I have looked at several MP4s that work and really don't know what to compare, nothing seems remarkably different. Here is the result from one that works followed by one that doesn't Audio: WORKS ID/String : 2 Format : AAC Format/Info : Advanced Audio Codec Format_Profile : LC CodecID : 40 Duration/String : 1h 44mn BitRate_Mode/String : Variable BitRate/String : 96.0 Kbps BitRate_Maximum/String : 127 Kbps Channel(s)/String : 2 channels ChannelPositions : Front: L R SamplingRate/String : 48.0 KHz Compression_Mode/String : Lossy StreamSize/String : 72.0 MiB (10%) Language/String : English Encoded_Date : UTC 2013-01-21 08:37:17 Tagged_Date : UTC 2013-01-21 08:37:18 Audio : No Sound ID : 2 Format : AAC Format/Info : Advanced Audio Codec Format profile : LC Codec ID : 40 Duration : 1h 35mn Source duration : 1h 36mn Bit rate mode : Variable Bit rate : 106 Kbps Maximum bit rate : 131 Kbps Channel(s) : 2 channels Channel(s)_Original : 1 channel Channel positions : Front: C Sampling rate : 44.1 KHz Compression mode : Lossy Stream size : 72.9 MiB (9%) Source stream size : 73.0 MiB (9%) Language : English Encoded date : UTC 2013-06-16 21:33:11 Tagged date : UTC 2013-06-16 21:33:12
The only difference I see is the sampling rates - 48 v 44. If the TV accepts mkv files, try this. Run MkvMerge and load the good and bad videos. Start by selecting only the Video and Audio ( V1 and A1)of the known good file and mux them into a new file and test it on the TV. If that works, select only V1 and A2 and mux them and test. If there is no audio, naturally suspect the second audio is the problem. Try V2 and A1 together. If that works it means the it's video is good and will work with audio that's created the same as the first. MkvMerge is part of MkvToolnix. http://www.videohelp.com/software/MKVtoolnix Image shows selection of V1 and A2.
