• encoding by using ffmpeg library

  22 août 2013, par Mustafe

  I am currently developing an application by using ffmpeg library. I have a problem with encoding pcm/raw datas. In ffmpeg/encoding_decoding.c source code, at line 146 in this function :

  buffer_size = av_samples_get_buffer_size(NULL, c->channels, c->frame_size, c->sample_fmt, 0);

  buffer_size is being calculated. My function always returns -22 which states an error. After a little examanation I noticed that in line 1888 at avcodec.h it is stated as following which shows the reason. Since CODEC_CAP_VARIABLE_FRAME_SIZE is set my function returns -22 and my program terminates. In this case the encoding code example in ffmpeg's website also could not work. How can I solve this problem ?

  encoding: set by libavcodec in avcodec_open2(). Each submitted frame except the last must contain exactly frame_size samples per channel. May be 0 when the codec has CODEC_CAP_VARIABLE_FRAME_SIZE set, then the frame size is not restricted. decoding: may be set by some decoders to indicate constant frame size

• Android - Lightweight solution for image video watermarking

  1er décembre 2015, par mtwain

  How to add image on video not using ffmpeg but using some another approach ? What more lightweight solutions exists for simple putting image on video ?

  I know few apps with this functionality that have very small size. What approach do they use ?
