I saw the example decoding_encoding.c that generates a video from dummy pictures... but how do I replace this part and read and encode my video? Can you help me, there are other examples or books available? Thanks!!! 2013/10/14 Dolevo Jay <[email protected]> Hi all, I have encoder and decoder application in separate projects. I use x264 to encode the incoming frames and use libav to decode them. If the frame has a specific resolution like 1366 x 768, the decode frame contains extra black border at the right side of the frame. I have debugged it and realized that the av_pic.linesize[0] is 50 more than the linesize during the encoding. Here is the code: lengthDec = avcodec_decode_video2(c1, av_pic, &pic, &pkt); if (pic) { avpicture_fill((AVPicture *)rgbFrame, RGBimg, PIX_FMT_RGB32, w, h); sws_scale(ctx, av_pic->data, av_pic->linesize, 0, h, rgbFrame->data, rgbFrame->linesize); } So, in this code, I decode the packet and convert the decoded data into the rgb. Why does the avcodec_decode_video2 returns a padded linesize? Could anyone tell me how I can eliminate the black border?
