Why h264 file needs transcoding
Posted: Sun Jul 31, 2011 10:18 am
I own a Panasonic TX-P42TV20 TV set. It usually plays h264 avi files just fine as long as the audio format is ok. I have however one file that, despite it being h264, refuses to play. I need to know what makes this file require transcoding and how I can create a transcoding rule that is as narrow as possible to select this file but not others that play fine in their original format.
The ffmpg -i info is:
Without any transcoding the TV says that it doesn't support the file format.
Just changing the container to mpegts (as in the standard Panasonic profile) the TV says it cannot open the file.
Transcoding the video to mpegts and mpeg2vido works:
Transcoding Transcoding to mpegts, mpeg2video and ac3 audio results in no sound (!).
What is is about this file that requires video transcoding? How can I create the appropriate, narrow rule? And why won't audio transcoding work (not required with this file, but I'm just curious)?
The ffmpg -i info is:
