Ive used many pieces of code found through searching google/ stack overflow to get to this point as is. The file has a good size but comes up as length 0.04 tells me that my time stamping must be broken between the frames / pkts, but I am unsure on how to fix this issue.
I tried inspecting the file with ffmpeg.exe using ffmpeg -i and outputting to a regular TS. It seems my code works more then I originally intended however, I am simply trying to output a bunch of all white frames.

Join two ISMV files
18 février 2015, par Violeta GrigorovaI am currently working on a project involving some task with ismv and ismc files. First of all let me give a brief explanation for the current situation. We are using windows based products only. We are getting some ismv and ismc video files from standard CCTV server. The ouput is only ismv in beggning but after indexing we get ismc file too. For each one hour long stream we are getting one ismv file and one ismc file.
What i need to do now is figure out a way to join multiple one hour streams. For example having a four hour long video will consist of 4 ismv video files.So far I tried ffmpeg codec, but without any success. The same goes for mp4split.
The error for ffmpeg is the following :
Could not find codec parameters for
stream 0 (Video : h264 (avc1 / 0x31637661), none, 586x480, 500 kb/s) : unspecifie
d pixel format
Consider increasing the value for the ’analyzeduration’ and ’probesize’ options
[concat @ 000000000436bd60]Executed with the following command :
ffmpeg.exe -f concat -i F.txt -c copy outputHere is the codec of the video taken with Media Info : http://tinypic.com/r/ff0h8z/8
I did not manage to find a version of mp4split to use. Can you please help me solve this problem ?
The final result should be one video only. This video should be a join between the videos given as input.

Build FFMPEG on MAC with my own license
16 février 2015, par AshishI am new in ffmpeg world. I want to build the ffmpeg exe on MAC os using its binary source. I have tried to build the exe and infact i succeeded in compiling exe but when i run that exe i got this line :

While surfing on internet i got an exe with different copyright holder. I also want to change that "the FFmpeg developer" with with my name. Please help me out how to do this ?
