error when converting mts to mp4
6 janvier 2015, par Chan KimI have many video files that I want to convert to mp4.
so I installed ffmpeg on my win7 PC (64 bit) which is using shared library.
I tried to convert an MTS file to MP4 and I get this error.
What is the problem ?$ ffmpeg -i 20140806114251.MTS 20140806114251.mp4

Error while opening encoder for output stream #0:1 - maybe incorrect parameters such as bit_rate, rate, width or heightEDIT : I thought I solved this problem by using
ffmpeg -i filename1.mts filename1.mkv
my Samsung LED TV supports mkv file and during the conversion, it shows
Stream #0:0 -> #0:0 (h264 (native) -> h264 (libx264))
Stream #0:1 -> #0:1 (ac3 (native) -> vorbis (libvorbis))But Alas ! my TV doesn’t support vorbis codec. It only supports mp3, ac3, lpcm, and ADPCM when using mkv container. So the question is : How do people select output audio codec ?

Decoding h264 in mp4 fragment from IIS Smooth Streaming
30 novembre 2013, par JulianSo I've decided to try and make my own client for IIS's Smooth Streaming as a learning exercise and I'm struggling to decode the mp4 fragments.
I have the following fragment :

part 1.mp4: could not find codec parametersAfter reading I found the PPS/SPS comes from the CodecPrivateData in the manifest that IIS gives me, which I have as :
000000016764001eacd940a03da10005161501312d000f162d960000000168ebe3cb22c0
Binary : http://www.mediafire.com/download/hm3av6h3i1g7ojf/CodecPrivateData
Which I think is annex b 00000001[SPS]00000001[PPS] but I have no idea what to do with it, I've tried putting it at the beginning of the file but get the same error, I also tried taking just the data in the mdat and sending that to ffmpeg but I get

part 1 - Copy.mp4: could not find codec parametersI seem to be missing something to get this to decode and I'm just not sure what so I'm hoping someone knowledgeable with h264 can help me out ! Ultimately I want to get this working in DirectShow but even getting it to work in ffmpeg would be a massive help !
