 Hello,

 using the ffmpeg library as part of an SDL application to play ogv video
 files, I face memory leaks at the end of the video. Ogv videos are
 generated with ffmpeg2theora.
 {{{
 $ ffmpeg2theora
 ffmpeg2theora 0.27 - Xiph.Org libtheora 1.1 20090822 (Thusnelda)
 }}}

 FFmpeg version :
 {{{

 }}}

 Commands called at the end of each frame decoding :
 {{{
 av_free_packet(&packet);
 SDL_DestroyTexture(bmpTex1);
 av_free(pFrame);
 av_free(pFrame_YUV420P);
 av_free(buffer_YUV420P);
 }}}

 At the end of the video :
 {{{
 av_free_packet(&packet);
 avcodec_close(pCodecCtx);
 av_close_input_file(pFormatCtx);
 }}}

 Using the same code, playing an avi video file it doesn't show any memory
 leak.
