Vous devez bénéficier d’un accès SSH à votre serveur et d’un compte "root" afin de l’utiliser, ce qui permettra d’installer les dépendances. Contactez votre hébergeur si vous ne disposez pas de cela.

Seek issue with ffmpeg
1er janvier 2015, par RameshI implemented one audio player using with ffmpeg for playing all format audio files in android.I used following code for seek the song.
int64_t seekTime = av_rescale_q(seekValue * AV_TIME_BASE,
AV_TIME_BASE_Q,
fmt_ctx->streams[seekStreamIndex]->time_base);
int64_t seekStreamDuration =
fmt_ctx->streams[seekStreamIndex]->duration;
int flags = AVSEEK_FLAG_BACKWARD;
if (seekTime > 0 && seekTime < seekStreamDuration)
flags |= AVSEEK_FLAG_ANY;
int ret = av_seek_frame(fmt_ctx, seekStreamIndex, seek_target,
flags);
if (ret < 0)
ret = av_seek_frame(fmt_ctx, seekStreamIndex, seekTime,
flags);
avcodec_flush_buffers(dec_ctx);Its working fine for most of the songs.But some of the mp3 songs getting duration problem.For example if the song length is 2 mins if i seek the song to some position then finally song ends with 2 mins 10 seconds.I get this issue with only mp3 songs.Without seeking the same song ends with exact time. I am using ffmpeg 2.1 The some code working fine with ffmpeg 0.11.1 Please provide any information about this issue.

export PKG_CONFIG_PATH
./configure --prefix="$HOME/ffmpeg_build" --extra-cflags="-I$HOME/ffmpeg_build/include" --extra-ldflags="-L$HOME/ffmpeg_build/lib" --bindir="$HOME/bin" \
--extra-libs=-ldl --enable-version3 --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libvpx --enable-libfaac \
